Three-dimensional sectional measurement approach for serial volume changes in shoulder muscles after arthroscopic rotator cuff repair.

Purpose: This study assessed the serial volume changes in multiple shoulder muscles simultaneously following arthroscopic rotator cuff repair (ARCR) by a three-dimensional (3D) modeling-based sectional measurement. These volume changes were correlated with background preoperative factors. Methods: Four consecutive magnetic resonance imaging scans (preoperatively and postoperatively at 3, 6, and 12 months) of 33 shoulders from 31 patients who underwent arthroscopic rotator cuff repair were examined. We focused on the sectional volume differences of the supraspinatus, infraspinatus, teres minor, and subscapularis between preoperatively and 3 months postoperatively (Dif.pre.3mo) and between 3 and 12 months postoperatively (Dif.3.12mo). The correlation between volume differences and clinical/demographic parameters was determined by a multivariate analysis. Results: No statistically significant differences were observed for most serial changes in the shoulder muscle volumes. The tear-site muscles (supraspinatus and infraspinatus) showed similar tendencies for volume changes, whereas the non-tear-site muscles (teres minor and subscapularis) differed. A negative correlation was observed between Dif.pre.3mo and Dif.3.12mo for the supraspinatus, infraspinatus, and teres minor. These perioperative volume differences might correlate with tear size and symptom duration in the supraspinatus, as well as with a history of steroid injections and work and sports activity levels in the infraspinatus and teres minor. Conclusion: The serial volume changes in multiple shoulder muscles after ARCR measured using our 3D sectional approach exhibited different tendencies and clinical implications depending on the primary and non-primary site of tears. Our method may serve as a potential indicator to facilitate muscle recovery and prevent the progression of postoperative muscle atrophy.

Outcomes comparison of elastic bandage versus lower-leg cast immobilization after anterior talofibular ligament repair.

PURPOSE: The aim of this study was to compare the clinical outcomes between patients with chronic ankle instability (CAI) undergoing arthroscopic anterior talofibular ligament (ATFL) repair who received elastic bandage treatment and those who received lower-leg cast immobilization. METHODS: CAI patients with isolated ATFL injury undergoing arthroscopic ATFL repair from January 2017 and August 2019 were included in the study. The visual analogue scale (VAS) at rest and during activities, American Orthopedic Foot and Ankle Society (AOFAS) score, Karlsson Ankle Functional Score (Karlsson score), and time of returning to walk, walk normally, work and sports were evaluated preoperatively, and at 6 months and 12 months follow-up. RESULTS: A total of 41 patients were included in this study. Among them, 24 patients accepted lower-leg cast fixation, and the other 17 patients were immobilized with elastic bandage. Compared to patients with lower-leg immobilization, patients with elastic bandage fixation had significantly lower VAS during activities (P = 0.021) and higher AOFAS score (P = 0.015) at 12 months follow-up. The Karlsson score at 6 months follow-up were significantly higher in elastic bandage group than those in lower-leg group (P = 0.011). However, no significant difference was observed in time of returning to walk, work and sports between the two groups. CONCLUSION: Elastic bandage treatment was better than lower-leg cast immobilization in terms of eliminating pain symptom at 12 months follow-up, and improving ankle functional outcome at 6 months follow-up. Moreover, the present study emphasized that lower-leg cast immobilization offered no advantages in arthroscopic ATFL repair postoperative immobilization. STUDY DESIGN: Cohort study; Level of evidence, 3.

The Subscapularis Healing Index: A New Scoring System for Predicting Subscapularis Healing After Arthroscopic Repair.

BACKGROUND: Previous research has emphasized the effect of prognostic factors on arthroscopic rotator cuff repair (ARCR) success, but a specific focus on subscapularis (SSC) tendon repair healing is lacking. PURPOSE: To identify prognostic factors for SSC healing after ARCR and develop the Subscapularis Healing Index (SSC-HI) by incorporating these factors. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: This was a retrospective study using prospectively maintained data collected from patients with isolated or combined SSC tears who underwent ARCR between 2011 and 2021 at a single institution with a minimum 2-year follow-up. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), and visual analog scale (VAS) pain scale. SSC tendon healing was evaluated via ultrasound at the final follow-up. Multivariate logistic regression analysis was performed to determine the factors affecting SSC healing, and based on these factors, the SSC-HI, which ranges from 0 to 15 points, was developed using odds ratios (ORs). RESULTS: Among 1018 ARCR patients, 931 met the inclusion criteria; 279 returned voluntarily for postoperative SSC ultrasound assessment. The overall healing failure rate was 10.8% (30/279). Risk factors for healing failure included female sex (P = .008; OR, 3.119), body mass index (BMI) ≥30 (P = .053; OR, 2.323), supraspinatus fatty infiltration ≥3 (P = .033; OR, 3.211), lower SSC fatty infiltration ≥2 (P = .037; OR, 3.608), and Lafosse classification ≥3 (P = .007; OR, 3.224). A 15-point scoring system comprised the following: 3 points for female sex, 2 points for BMI ≥30, 3 points for supraspinatus fatty infiltration ≥3, 4 points for lower SSC fatty infiltration ≥2, and 3 points for Lafosse classification ≥3. Patients with ≤4 points had a 4% healing failure rate, while those with ≥9 points had a 55% rate of healing failure. Patients with a healed SSC reported significantly higher ASES (healed SSC: ΔASES, 44.7; unhealed SSC: ΔASES, 29; P < .01) and SSV (healed SSC: ΔSSV, 52.9; unhealed SSC: ΔSSV, 27.5; P < .01) and lower VAS (healed SSC: ΔVAS, -4.2; unhealed SSC: ΔVAS, -3; P < .01) scores compared with those with an unhealed SSC. CONCLUSION: The SSC-HI scoring system integrates clinical and radiological factors to predict SSC healing after surgical repair. Successful SSC healing was found to be associated with enhanced functional outcomes, underscoring the clinical relevance of SSC healing prediction in the management of these tears.

Long-term clinical outcomes of arthroscopic supraspinatus tendon repair using the single anchor tension band technique - Minimum 5-years follow-up.

Background: The primary aim of this study was to assess the long-term patient reported outcomes of arthroscopic rotator cuff tear (ARCR) using a single anchor tension band (TB) technique for small and medium supraspinatus tears at minimum 5-years follow-up. Methods: A retrospective cohort study of consecutive ARCRs of small and medium supraspinatus tears using a knotless single anchor TB technique with minimum 5-year follow-up was carried out. Outcomes of interest included: range of motion (ROM) on examination under anaesthesia (EUA), visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) scores, Oxford Shoulder Score (OSS) and Short-Form (SF-12). Results: From 243 consecutive ARCR procedures, 82 patients with a mean age of 55 ± 9.5 years met the inclusion criteria at 6.7 ± 1.5 years follow-up. There were significant improvements in VAS (5.5 ± 2.2 vs. 0.7 ± 1.5), ASES (47.6 ± 16.8 vs. 92.8 ± 13.0), OSS (31.3 ± 7.2 vs. 45.3 ± 3.5) and SF-12 (37.6 ± 7.6 vs. 50.3 ± 7.7) post-operatively (all p < 0.001). Conclusions: The single anchor TB ARCR technique has excellent patient reported outcomes at a minimum of 5 years and is suitable for supraspinatus tears smaller than 20 mm in the sagittal plane. Level of evidence: Level IV; Consecutive Case Series.

Hypermobile lateral meniscus: A systematic review of current treatment options.

PURPOSE: The reliable data on the incidence of hypermobile lateral meniscus (HLM) and its clinical manifestations, diagnostic methods and therapeutic approaches are limited. This systematic study aimed to review available treatment options for HLM and the outcomes of each approach. METHODS: A systematic search was performed in four electronic databases (PubMed, EMBASE, Scopus, Web of Science) to identify studies in which arthroscopically confirmed cases of HLM were treated surgically or nonsurgically, and the required data comprising study characteristics, patient data, treatment approaches and outcome measures were extracted from eligible studies. RESULTS: Twenty studies with a total of 212 patients (138 males and 74 females) and 219 knees were included. The most frequently reported symptoms were locking sensations, knee pain, giving way and snapping. Treatments used by the studies were: radiofrequency energy in two studies; arthroscopic partial meniscectomy in one study; open surgery in two studies; and arthroscopic meniscal repair in 17 studies. Eleven studies used an all-inside repair method and an inside-out meniscal repair was reported in eight studies. Three studies reported the usage of posterior arthroscopy for therapeutic or diagnostic approaches. Evaluation of symptom resolution was the main outcome measurement for which almost all of the studies stated relief of symptoms after intervention. CONCLUSION: Despite the lack of definite consensus about the most appropriate intervention for HLM, therapeutic preference was directed towards arthroscopic all-inside and inside-out repair techniques. Although the surgeon's decision remains the key factor in choosing the most suitable treatment option for each individual, posterior arthroscopic meniscal repair may be considered as a better option for HLM treatment according to the findings of this review. LEVEL OF EVIDENCE: Level IV.

Arthroscopic double row partial articular supraspinatus tendon avulsion bridge repair technique for shoulder: A transtendinous approach.

Partial articular supraspinatus tendon avulsion (PASTA) lesions, a subset of partial rotator cuff tears, pose a surgical challenge, disrupting the integrity of the supraspinatus tendon. Transtendinous repair is the preferred choice in young individuals for limiting tear progression and preserving intact, high-quality cuff tissue, thus preventing tendon shortening, as compared to the tear completion and repair technique. Our approach leverages these advantages, specifically those indicated for Ellman's Grade 3 tears and cases where conservative treatments have failed. In our technique, we employ progressive dilation, anchor drill sleeve insertion to facilitate medial row anchor placement, followed by percutaneous spinal needles for suture shuttling, and finally locking sliding knots for compressive medial row repair, followed by lateral row fixation for additional stability. This method accelerates rehabilitation and restores optimal shoulder function.

All-arthroscopic versus mini-open double row rotator cuff repair - A prospective randomised control study based on functional and radiological outcomes.

Purpose: In an era where arthroscopic rotator cuff repair is dominant in the United States (77.9 % preference) compared to open surgery (53.33 %), a shift towards minimally invasive All-Arthroscopic (AA) techniques over classical Mini-Open (MO) repair is emerging. This study explores current trends in shoulder procedures in India and compares functional outcomes and radiological repair integrity between AA and MO techniques, which are understudied in the Indian context. Methodology: In this prospective study, 60 patients (30 in the AA group and 30 in the MO group) with rotator cuff tears underwent assessment. Pre/post-operative clinical evaluations and 12-month follow-ups using UCLA and Oxford Shoulder Score, along with preoperative MRI and postoperative USG, were conducted. Results: At one-year follow-up, the AA group showed better functional outcomes (53.3 % excellent/good vs. 30.0 % in MO). No significant radiological differences (Sugaya grading) were found. Tear size was comparable with no association with functional/radiological outcomes. Conclusion: The AA group demonstrated favourable functional outcomes, matched to MO group findings, which is in accordance with global studies. Despite higher costs, the increasing popularity of AA in India is justified by enhanced results and reduced postoperative discomfort.

Medial Patellofemoral Ligament Reconstruction: A Case Report for an Integrated Rehabilitation Approach.

Medial patellofemoral ligament (MPFL) reconstruction is a surgical treatment, primarily indicated for patients grappling with recurrent patellar instability stemming from traumatic injury or underlying anatomical anomalies. This abstract aims to elucidate the indispensable role of physiotherapy in the post-operative rehabilitation trajectory for individuals subjected to MPFL reconstruction. Physiotherapy emerges as a linchpin in securing a triumphant outcome, fostering the healing of patellar stability, augmentation of range of motion (ROM), and bolstering muscular strength while concurrently mitigating potential complications. The abstract accentuates salient facets of a physiotherapeutic regimen, encompassing prompt post-operative mobilization, meticulously tailored exercise paradigms, adept utilization of manual therapy modalities, and comprehensive patient education. Notably, this collaborative endeavor between orthopedic surgeons and physiotherapists is pivotal in optimizing patient convalescence, restoring them to their pre-injury functional acumen. A paramount emphasis is placed on individualized rehabilitation strategies, gradual and systematic exercise protocols, and patient adherence, thereby underscoring how the harmonious synergy between surgical and physiotherapeutic interventions augments the prospects of achieving a successful MPFL reconstruction outcome.

Knotted or knotless double-row rotator cuff repair retear rates: a systematic review and meta-analysis.

Background: Arthroscopic rotator cuff tear repair techniques used to rely on knot-tying double row techniques, but the advent of knotless transosseous equivalent procedures introduced a new variable to the debate. The purpose of this study is to determine which technique is associated with lower retear rates. For its' biomechanical advantages, the authors' hypothesis is that knotless techniques would have lower retear rates. Methods: A systematic literature search was performed via PubMed and Google Scholar by two independent reviewers following PRISMA guidelines. Papers reporting retear rates after rotator cuff arthroscopic repair using knotted double-row or knotless transosseous equivalent techniques, evaluated by magnetic resonance imaging at least 6 months after surgery, were retrieved. Studies that do not differentiate between techniques and nonclinical reports were excluded. Eligible data was analyzed with Review Manager 5.4.1 using Mantel-Haenszel statistics with a fixed effect model. Results: The authors' initial literature search retrieved 511 reports. After the selection process, 24 articles were available for this review, and 9 were eligible for meta-analysis. A comparison of 1888 subjects from noncomparative reports and a meta-analysis of reports in which both techniques were studied could not show a statistically significant difference in technique retear rates. Discussion and conclusion: The current report revealed no significant difference in retear rates between the two arthroscopic repair techniques. Studies' quality was a limitation. Only two reported level 1 evidence. This review could not control variables such as cuff tear size, tissue quality, or individual comorbidities. Larger and longer follow-up studies could be helpful to further investigate this topic.

Clinical Outcomes and Tendon Healing After Arthroscopic Isolated Subscapularis Tendon Repair: Results at Midterm Follow-up.

Background: Few studies have reported clinical outcomes and tendon healing rates after arthroscopic isolated subscapularis (SSC) repair (AISR). Purpose/Hypothesis: The primary purpose of this study was to evaluate clinical outcomes and tendon healing after AISR. It was hypothesized that AISR would result in satisfactory clinical outcomes along with a high rate of tendon healing at the midterm follow-up. The secondary purpose was to assess the influence of tear size and muscle atrophy on SSC tendon healing and patient-reported outcomes. It was hypothesized that both would be negatively correlated with healing but would have no effect on clinical outcomes . Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was conducted on prospectively collected data for 77 patients who underwent primary AISR between 2011 and 2021 at a single institution, with a minimum 2-year postoperative follow-up for all patients. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, the Subjective Shoulder Value (SSV), and the visual analog scale for pain. Repair techniques and concomitant procedures were also collected. SSC tendon healing was evaluated via ultrasound at the final follow-up. Linear regression analysis was performed to determine factors affecting SSC healing. Results: The mean follow-up was 58.1 ± 3.3 months. ASES scores significantly improved from 41.5 to 81.6, and the SSV improved from 38.2 to 80.5 (P < .01 for both). Among the 40 patients (51.9%) who underwent postoperative ultrasound, 87.5% showed complete tendon healing. There were no significant differences in outcome scores between healed and unhealed tendons. Increased muscle atrophy and larger tears were correlated with failure of SSC healing (ß = -0.285 [P = .015] and ß = -0.157 [P = .045], respectively). Conclusion: Improved clinical outcomes and an overall high rate of tendon healing were seen at the midterm follow-up after AISR. Smaller tear sizes with less muscle atrophy were correlated with improved tendon healing. However, even when the tendon incompletely healed, the procedure improved functional outcomes.

A Comparative Analysis of Complication Rates in Arthroscopic Repair of the Lateral Ankle Ligament and the Brostrom-Gould Technique: A Systematic Review.

Injury to the lateral ligament is the most common cause of chronic lateral ankle instability. Lateral ankle instability is usually managed through conservative management, but surgery is indicated if this fails to relieve the symptoms. Surgical repair of the lateral ligament involves many surgical techniques including the arthroscopic repair technique and the modified Brostrom-Gould technique. Due to the minimal research on the complication rates of both techniques, this systematic review aims to establish the complication rates. To obtain articles, a detailed systematic search of MEDLINE, PubMed, Embase, Web of Science, and Cochrane Library was performed. The articles found using the keywords "arthroscopic," "Brostrom," and "Brostrom-Gould" were reviewed by two independent authors. The authors then selected the articles according to our predetermined eligibility criteria. The articles that met our inclusion were then chosen for data extraction. Specific details obtained from the study included the author's details, the setting of the study, and the complications of the study. The online search yielded 975 articles, but only 44 met our inclusion criteria and were included in the review. The total sample size for the review was 2041 patients, the modified Brostrom technique was performed on 760 patients while on the remaining 1281 patients, arthroscopic repair was performed. On the characteristics of the sample, the age of the samples ranged from eight years to 83 years, while the mean BMI ranged from 21.0 kg/m² to 25.3 kg/m². The various complication rates included superficial peroneal nerve injury (2.3% in arthroscopic Brostrom and 0.65% in the Brostrom-Gould), wound infections (1.3% in arthroscopic Brostrom and 1.8% in the Brostrom-Gould), persistent pain (1.5% in the arthroscopic Brostrom and 1.1% in the Brostrom-Gould), and lastly recurrent instability (0.31% in arthroscopic Brostrom and 3.0% in the Brostrom-Gould). Overall, the complication rates of the arthroscopic repair were 11.00%, while those of the modified Brostrom-Gould were 10.65%. The study demonstrated that although the arthroscopic technique had higher complication rates than the modified Brostrom technique, the difference was insignificant. Therefore, we concluded that surgeons performing the arthroscopic Brostrom technique should have good arthroscopic skills to minimize complications.

A new arthroscopic repair technique for triangular fibrocartilage complex using an intracapsular suture: an outside-in transfer all-inside repair.

BACKGROUND: Arthroscopic repair is a promising, minimally invasive surgical technique for patients with Palmer type 1B peripheral triangular fibrocartilage complex (TFCC) tears. Although several arthroscopic techniques are effective for repairing Palmer type 1B TFCC tears, some shortcomings remain. So, we report an arthroscopic repair technique for the treatment of Palmer type 1B Atzei class 1 TFCC tears using an intracapsular suture: an outside-in transfer all-inside repair. METHODS: A retrospective analysis of 38 Palmer type 1B TFCC injury patients admitted to our hospital were randomly divided into 2 groups. The group A was sutured from the outside to the inside, with a total of 21 cases; the group B was sutured with the new arthroscopic repair technique, with a total of 17 cases. Observe and compare the VAS scores and modified Mayo wrist function scores of all patients before 3, and 6 months after the operation and evaluate the incidence of thread knots in patients with different treatment methods. The methodology was performed an arthroscopic intracapsular suture using an outside-in transfer, all-inside repair technique, which is a modified method of the outside-in and all-inside technique using the needle of a 10-mL sterile syringe, for Palmer type 1B TFCC tears. A No. 2 polydioxanone suture was threaded through the needle and entered the wrist joint. Next, the needle was withdrawn carefully along the suture to the proximal tear ulnar surface of the TFCC and penetrated the TFCC, exiting the articular cavity surface of the ulnar side of the torn TFCC. Finally, arthroscopic knotting was performed. RESULTS: This new treatment was as effective as the previously arthroscopic techniques and had the advantages of no additional incision and decreased risk of operation-related complications. The incidence of thread knots in the group A (28.57%) was significantly higher than that in the group B (0%), and the difference was statistically significant (P = 0.024). There was no significant difference in VAS score and modified Mayo wrist function scores between the two groups (P > 0.05). CONCLUSIONS: The outside-in transfer, the all-inside repair technique is suitable for Palmer type 1B Atzei class 1 TFCC tears. We recommend this technique as a useful alternative to the conventional methods of repairing Palmer type 1B TFCC tears.

A study on Subscapularis augmented Bankart repair (SB) vs capsulo-labral Bankart repair (CB) for recurrent anterior shoulder dislocation with moderate glenoid bone loss (< 20 %) in non-athletepopulation.

Introduction- Subscapularis augmented Bankart repair (SB) is a novel arthroscopic technique of tenodesis of upper 1/3rd fibers of subscapularis tendon to capsulo-labral repair of Bankart lesion. Treatment of Bony Bankart lesion with glenoid bone loss % (GBL%) 10%-20 % is still a grey zone where bone augmentation procedures are an overtreatment and capsulo-labral repair is associated with high recurrence. Methodology: A retrospective study of 30 patients with h/o anterior instability with GBL%<20 % were classified into two groups. SB group included patients managed with arthroscopic subscapularis augmentation while CB group included patients managed with arthroscopic capsulo-labral repair. These patients were followed up after a minimum of 24 months post-surgery and functional outcomes evaluated using WOSI, ASES and ROWE scores. Results: Patients in the SB group showed superior functional outcomes for WOSI and ROWE scores. Considering postoperative shoulder pain, the median ROWE-P (pain) score was better for SB group (10/10) when compared to CB group (5/10). Patients under SB group were more comfortable with physical symptoms of their shoulder (WOSI-P average 60/1000) and were more likely to continue their recreational sports activity (WOSI- sports for SB 63.7 and CB 119.5. In our study, none of the 15 SB patients had any restriction in range of shoulder movements [ROWE-M score of 10]. Subscapularis augmented Bankart repair is associated with minimal restriction of shoulder range, better pain relief, better acceptability and smoother return to daily living and occupation and can be considered as a routine for every patient with GBL<20 %.

Quantitative evaluation of calcaneofibular ligament injury on the oblique coronal view of magnetic resonance imaging in chronic lateral ankle instability.

BACKGROUND: In the treatment of chronic lateral ankle instability (CLAI), the repair of the calcaneofibular ligament (CFL) and anterior talofibular ligament (ATFL) is still being discussed, possibly due to the difficulty in assessing CFL injuries. In particular, it is challenging to evaluate the extent of CFL deficiency quantitively. We hypothesized that CFL tension change would alter morphology of the CFL on magnetic resonance imaging (MRI) and that measuring this morphological change allows assessing CFL injury quantitatively. Thus, this study aimed to analyze the feasibility of quantitatively assessing CFL injuries using MRI. METHODS: Sixty-four ankles with CLAI were included and divided into two groups: with (ATFL and CFL group, 31 ankles) or without CFL repair (ATFL group, 33 ankles) in addition to arthroscopic ATFL repair. The angle between the CFL and calcaneal axis (CFLCA) and the bending angles of the CFL was defined as the flexed CFL angle (FCA) were measured on the oblique CFL view of preoperative MRI. The diagnostic abilities of these angles for CFL injury and correlations between these angles and stress radiographs were analyzed. RESULTS: The sensitivity and specificity of CFLCA were 86.7 % and 88.7 %, and those of FCA were 63.3 % and 77.4 %, respectively. The combination of CFLCA and FCA improved the sensitivity to 93.3 %. The cutoff points of CFLCA and FCA were 3.8° and 121.2°, respectively. There were significant moderate and weak correlations between the talar tilting angle and CFLCA or FCA (rs = -0.533, and rs = -0.402, respectively). The CFLCA and FCA were significantly smaller in the ATFL and CFL group than those in the other groups. CONCLUSIONS: Measurement of CFLCA and FCA in oblique CFL view on MRI could be useful for the quantitative evaluation of CFL injury in patients with CLAI． LEVEL OF EVIDENCE: Level IV. case-control study.

A Comparative Analysis Between Conservative Treatment, Arthroscopic Repair, and Biceps Tenodesis in Superior Labral Anterior-Posterior (SLAP) Lesions.

Background "Throwing shoulder" hinders athletes' shoulder functions, causing pain, weakness, and performance reduction due to anatomical, physiological, and biomechanical factors. Anatomical issues include superior labral anterior-posterior (SLAP) injuries, rotator cuff injuries, and glenohumeral instability. Methods This study compared arthroscopic labral repairs in patients under 40 years old with shoulder injuries between 2015 and 2017. Sixty eligible patients were divided into three groups: conservative treatment, arthroscopic repair, and tenodesis. Measures included pain, functional scores, and the range of motion pre-/post-operation. Results At the last follow-up, pain relief and functional improvement were most significant with tenodesis (97% pain relief, 95% functional improvement), followed by repair (85% pain relief, 70% functional improvement), and least in conservative treatment (45% pain relief, 40% functional improvement). While all treatments significantly reduced pain and improved function (p<0.001), tenodesis demonstrated the highest effectiveness, suggesting it as a potentially preferred method. Significant improvements in pain relief and function were observed across all methods; however, surgical options suggested improved outcomes. Conclusion Our study compares conservative treatment, arthroscopic labral repair, and biceps tenodesis (BT) for SLAP lesions, highlighting significant pain relief and functional improvement across all. Conservative treatment suits patients with milder symptoms, while arthroscopic repair addresses larger tears. As the effectiveness of arthroscopic treatment is not inferior to conservative one, BT excels in cases of substantial bicep involvement.

Arthroscopic repair with transosseous sling-suture technique for acute and chronic bony Bankart lesions.

Background: Failure to fix the fractured fragment can result in bony fragment resorption and consequent glenoid bone loss. Current arthroscopic repair techniques might lead to insecure fixation and refracture. The purpose of this study was to evaluate the effectiveness of the transosseous sling-suture technique for bony Bankart lesions, and to compare the clinical outcomes for acute and chronic bony Bankart lesions treated with this technique. Methods: A retrospective case series consisting of 46 patients with bony fracture of the glenoid rim following traumatic injury was identified from May 2015 to August 2020. The patients were divided into the acute lesion group and the chronic lesion group according to the time from first injury to surgery. The size of bone fragment was used to group the patients into the small and the medium sized fragment groups. All the patients underwent arthroscopic repairs using the transosseous sling-suture technique. Preoperative and postoperative evaluations including Rowe score, West Ontario Shoulder Instability Index (WOSI), Visual Analogue Scale (VAS) for pain scores, ROMs and number of dislocations were recorded. No significant differences were found in the comparisons of postoperative ROMs ang functional outcomes regarding between the small and the medium sized fragment groups. Results: No dislocations occurred for both groups postoperatively. At the last follow-up, all the ROMs (including anterior flexion, abduction, external rotation and internal rotation at the side), the Rowe score, the WOSI score and the VAS score for pain in the both groups were significantly improved compared to the preoperative evaluations (all Ps < 0.001). In the comparisons between the acute and the chronic lesion groups, significantly greater anterior flexion (158.9 ± 8.9° vs. 153.0 ± 6.4°, P = 0.037), abduction (167.7 ± 10.1° vs. 161.0 ± 7.0°, P = 0.035) and external rotation at the side (88.3 ± 6.4° vs. 83.5 ± 5.5°, P = 0.024) were found in the acute lesion group. The comparisons of the Rowe score (86.0 ± 7.5 vs. 87.5 ± 10.6, P = 0.319), the WOSI score (223.5 ± 56.3 vs. 185.0 ± 79.9, P = 0.062), the VAS score for pain (0.4 ± 0.2 vs. 0.3 ± 0.2, P = 0.324) and the internal rotation at the side (74.6 ± 13.2° vs. 80.5 ± 11.1°, P = 0.116) between these two groups did not demonstrate significant differences between the two groups. Conclusion: This arthroscopic transosseous sling-suture repair technique for shoulder anterior instability with acute and chronic bony Bankart lesion can restore joint stability, improve clinical outcomes and range of motion postoperatively. The acute bony Bankart lesion using the current technique can produce better range of motion compared to the chronic lesion. Study design: Retrospective case series; Level of evidence, 4.

The effect of biceps tenotomy on superior humeral migration in arthroscopic repaired full-thickness supraspinatus tears.

Background: Lesions of the long head of the biceps (LHB) tendon are a prevalent injury that frequently coexists with rotator cuff injuries. This study aimed to assess the effect of supraspinatus (SST) repair with concurrent LHB tenotomy on superior migration of the humeral head. The acromiohumeral distance (AHD) was determined via ultrasound to evaluate the superior migration of the humeral head. Methods: The study population was retrospectively recruited from patients who underwent unilateral arthroscopic repair of isolated degenerative full-thickness SST tears between January 2017 and December 2019. Patients were divided into 2 subgroups based on whether they underwent LHB tenotomies during arthroscopy. While 37 patients underwent arthroscopic single-row SST repair, the other 33 patients underwent arthroscopic single-row SST repair with LHB tenotomy. The subject group consisted of people who had undergone arthroscopic shoulder surgery. Contralateral shoulders without rotator cuff injuries were included in the control group. The AHD and SST thicknesses of patients were examined via the ultrasound in both groups and subgroups. Results: The mean age in the SST repair group was 55.52 ± 4.58 years (range, 46-63 years), whereas it was 58.24 ± 3.98 (range, 52-73 years) in the SST repair + LHB tenotomy group. In the SST repair group, 57.6% of patients were female and 42.4% were male, whereas 56.8% and 43.2% were in the SST repair + LHB tenotomy group, respectively. The mean body mass index was 28.06 ± 1.31 kg/m2 (range, 25.7-31.2 kg/m2) in the SST repair group and 28.95 ± 1.79 kg/m2 in the SST repair + LHB tenotomy group. Groups were not different for sex, surgery side, dominant side, tear size, and follow-up time; however, the SST repair + LHB tenotomy group had significantly higher mean age and body mass index than the SST repaired group. The mean AHD value and SST thickness were significantly less in both the rotator cuff repair group and the rotator cuff repair + LHB tenotomy group compared to the healthy shoulder. The mean AHD value was significantly lower in the SST repaired + LHB tenotomy group than in the SST repair group (P = .02). Conclusion: The AHD was narrowed in patients who underwent LHB tenotomy and radiologically demonstrated the depressor effect of the LHB tendon on the humeral head. As a secondary outcome, we demonstrated that regardless of tenotomy, AHD could not be restored in patients who underwent arthroscopic single-row SST repair.

One-stage rotator cuff repair in stiff shoulders shows comparable range of motion, clinical outcome and retear rates to non-stiff shoulders: a systematic review.

BACKGROUND: One-stage treatment involving rotator cuff repair and shoulder capsule release is mainly used to treat patients with rotator cuff tears (RCTs) and concomitant shoulder stiffness. Despite the increasing attention to the efficacy and safety of one-stage treatment, controversy still remains. Therefore, this systematic review aims to summarize the indications, operation procedure and rehabilitation protocol, and compare the range of motions (ROMs), functional outcomes and retear rates of one-stage treatment for RCTs in stiff shoulders and non-stiff shoulders. METHODS: Multiple databases (PubMed, the Cochrane Library, Embase and MEDLINE) were searched for studies that investigated outcomes after one-stage treatment for RCTs concomitant with shoulder stiffness compared with rotator cuff repair for RCTs alone, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Descriptive statistics, including range of motion, patient-reported outcome and retear rate, are presented without meta-analysis due to the heterogeneity and low levels of evidence. RESULTS: A total of 9 cohort studies were included, with 305 patients treated with one-stage treatment involving rotator cuff repair and simultaneous shoulder capsular release and 1059 patients treated with rotator cuff repair alone. Patients in both groups had significant symptom improvement and functional recovery after the one-stage treatment for the stiffness group and standard repair for the non-stiffness group, and most patients could return to normal life and work within 6 months after the operation. The retear rate in the one-stage treatment group was not higher than that in the rotator cuff repair group. No statistically significant differences between the two groups were observed in terms of range of motion and patient-reported outcomes in the vast majority of studies at the final follow-up, including the visual analog scale for pain, the Constant score, the American Shoulder and Elbow Surgeons score, the University of California Los Angeles Shoulder Score, the Oxford shoulder score and the Simple Shoulder Test. CONCLUSION: One-stage treatment for RCTs in stiff shoulders provides comparable ROM and patient-reported clinical outcomes as rotator cuff repair for non-stiff RCTs. In addition, the rate of postoperative retear in stiff shoulder treated with one-stage treatment was not higher than in non-stiff shoulders.

AMR Sign - An Arthroscopic S-shaped Fold Signifying Adequate Medial Meniscus Repair.

Introduction: The preferred management of medial meniscus tears has notably moved from meniscectomies towards repair. With a higher volume of meniscal repairs being done all across the world with every passing day, the lack of an objective and definitive sign suggesting the adequacy of its repair is daunting. The purpose of our study was to introduce a unique and novel arthroscopic sign formed after adequate repair of the medial meniscus, the AMR (Adequacy of Medial meniscus Repair) sign. We hypothesised that it is not only the objective end point for repair, but can also form the indicator for excellent clinical, functional, and radiological outcome even in the long term. Materials and methods: This was a multicentric, prospective study initiated by the corresponding author, and the findings validated subsequently by the other authors. Overall, it included 804 patients of isolated medial meniscus tear operated with arthroscopic all-inside technique between January 2014 and December 2017. Patients were segregated into three groups based on whether an S-shaped curve in the free, inner edge of the medial meniscus sign was formed post-repair, lost after further tightening, or not formed upon subjective completion of repair. All the patients were followed-up and evaluated based of medial joint line tenderness, McMurray's test for medial meniscus, IKDC score, WOMET score, and radiologically using an MRI at the terminal follow-up. Results: The mean terminal follow-up was 42.34±4.54 months. There was significant (p<0.01) improvement in all patients at the terminal follow-up post-surgery, irrespective of the group. The group in which AMR sign was formed and maintained showed a significantly better functional outcome on terminal follow-up as well as lower failure rates compared to the other two groups. Conclusion: AMR sign is an S-shaped fold at the inner, free edge of medial meniscus, formed after an adequate repair of isolated medial meniscus tear, as viewed on arthroscopy. It is an objective sign denoting regained integrity of the collagen architecture of the medial meniscus following repair. It is also a reliable indicator of excellent long term functional, clinical, and radiological outcome and also lower failure rates in patients after arthroscopic medial meniscus repair.

Subacromial Balloon Spacer Versus Partial Rotator Cuff Repair in the Treatment of Massive Irreparable Rotator Cuff Tears: Facility Personnel Allocation and Procedural Cost Analysis.

Background The subacromial balloon is a novel technology that has shown promise in managing a select patient population with massive irreparable rotator cuff tears. The purpose of this study was to quantify the true facility cost difference between subacromial balloon placement (SBP) and partial rotator cuff repair (PCR). Methodology A prospective cohort of patients with massive irreparable rotator cuff tears randomized to SBP versus PCR between 2015 and 2018 was retrospectively reviewed. Demographic variables, medical comorbidities, and range-of-motion (ROM) outcomes for all patients were recorded. True facility costs with respect to personnel were calculated using a time-driven activity based-costing (TDABC) algorithm and were classified into personnel costs and supply costs. Results Seven patients were treated with PCR compared to nine treated with SBP. No significant differences were observed with respect to demographic characteristics. Postoperative mean external rotation was 37° in SBP patients significantly higher than that of PCR patients at 8° (P = 0.023). Personnel time and cost differences while in the operating room (OR) were significantly less for the SBP ($605.58) compared to PCR ($1362.76) (P < 0.001). Implant costs were higher for SBP when compared to PCR, whereas disposable equipment costs were higher for PCR when compared to SBP. The total mean true facility cost was $7658.00 for SBP, significantly higher than that of PCR at $3429.00 (P < 0.001). Conclusions Despite the substantial reduction in personnel costs seen with SBP, the true facility cost of SBP was significantly higher than that of PCR. As this novel technology is used more ubiquitously and its price is negotiated down, the cost savings seen in personnel and OR time will become more significant. Future prospective cost analyses should follow up on the changes in implant costs and account for potential anesthesia cost savings.
