ABSTRACT

INTRODUCTION: Arthroscopic revision anterior shoulder instability repair has been proposed, and early clinical results have been promising. However, long-term results after this procedure and the probable risk factors for failure have not been sufficiently discussed in the literature. MATERIALS AND METHODS: Thirty-eight patients who were diagnosed with recurrent anteroinferior shoulder instability after failed Bankart repair, treated with ACRR between September 1998 and November 2003 and able to be contacted were included. Of these patients, 2 were excluded from the study due to the use of SureTak anchors for fixation, and 5 other patients refused to participate in the study due to lack of interest (3 patients) or lack of time (2 patients). The remaining shoulders were clinically examined at a minimum of ten years after surgery via the ASES, Constant, AAOS, Rowe, Dawson and VAS scores for pain and stability. Degenerative arthropathy was assessed with the modified Samilson-Prieto score. RESULTS: All 31 remaining shoulders were evaluated at a mean time of 11.86 years (142.4 months) after surgery. Six patients (19.35%) reported redisolcation after the revision procedure, 4 of whom were affected by a new significant shoulder trauma. The ROWE and Constant scores improved significantly. Moderate to severe dislocation arthropathy was observed in 19.4% of patients. Five patients (16.2%) were not satisfied with the procedure. CONCLUSION: Long-term follow-up after ACRR shows predictable results, with a high degree of patient satisfaction, good to excellent patient-reported outcome scores and minimal radiological degenerative changes. However, with an average recurrence rate of 19.3% after 11.86 years, the redislocation rate appears high. With careful patient selection, recurrence rates can be significantly reduced.

ABSTRACT

Injury to the sternoclavicular joint (SCG) is very rare, accounting for 3% of shoulder injuries and < 1% of instabilities. Consequently, both the treatment of acute instabilities and their subsequent states (chronic instabilities/SCG arthrosis) are controversial. While treatment has so far been mostly conservative, in recent years there has been a trend towards surgical therapy.Considerable violence, such as that found in traffic accidents or contact sports, can tear the extremely stable ligaments between the medial clavicle and sternum. While anterior dislocation is easier to reduce in most cases, instability remains in up to 50% of cases. In most cases, posterior instability requires rapid reduction, particularly due to the anatomical proximity to important cardio-pulmonary structures. If this succeeds, the rate of persistent instabilities is low. For chronic instability, reconstruction/augmentation of the ligament apparatus with tendon grafts in the "Figure of 8 configuration" has proven to be the standard technique in recent years.

ABSTRACT

INTRODUCTION: The purpose was to compare the arthroscopic rod technique to stress ultrasound in the dynamic assessment of lateral elbow instabilities. MATERIALS AND METHODS: Fifteen elbows of eight specimen with a mean age of 66.4 ± 13.3 years were assessed in a prone position following a defined dissection setup. After evaluation of the native status, an arthroscopic dissection of the radial collateral ligament (RCL) or lateral ulnar collateral ligament (LUCL), and finally of entire capsuloligamentous structures was performed. Three raters examined each state (native, RCL or LUCL lesion, complete lesion) with the arthroscopic rod technique in 90° flexion and with stress ultrasound in 30 and 90° flexion. The intra-class correlation coefficient (ICC) was calculated to assess the interrater reliability as well as test-retest reliability for each testing modality (arthroscopy and ultrasound). RESULTS: The arthroscopic rod technique showed a superior interrater and test-retest reliability of 0.953 and 0.959 (P < 0.001), respectively, when compared to stress ultrasound with an ICC of 0.4 and 0.611 (P < 0.001). A joint space opening during arthroscopy of > 6 mm humero-ulnar or > 7 mm humero-radial was indicative for a lateral collateral ligament lesion. However, a differentiation between an isolated RCL or LUCL tear was not possible. A lateral joint opening of ≥ 9 mm was only observed in complete tears of the lateral capsuloligamentous complex. CONCLUSIONS: The arthroscopic rod technique showed a superior interrater and test-retest reliability when compared to stress ultrasound. Arthroscopic assessment for radial elbow instability was found to be reliable and reproducible. A joint gapping ≥ 9 mm in the arthroscopic evaluation is a sign for a complete insufficiency of the radial capsuloligamentous complex. However, it is not possible to precisely distinguish between a lesion of the RCL or LUCL by arthroscopy. On the basis of our results, dynamic ultrasound testing may be inappropriate to objectify lateral elbow instability.

ABSTRACT

BACKGROUND: Since the introduction of stemless anatomic shoulder arthroplasty, many studies have been published on anatomic implants. For reverse stemless implants, however, there are only a few clinical follow-up studies available. The current clinical case series aims to present clinical and radiological outcomes of a new stemless reverse prosthesis system (Lima Shoulder Modular Replacement stemless). METHODS: We prospectively evaluated the outcome of 56 stemless total shoulder arthroplasties in 56 patients with a mean age of 61.2 years (46-76 years) at the time of implantation at a minimum follow-up of 24 months (range 24-41 months). All patients were physically and radiologically examined. Clinical outcomes were evaluated by using the Constant-Murley Score and the Subjective Shoulder Value. RESULTS: The mean Subjective Shoulder Value was 84.27% at the latest follow-up. Significant improvements from preoperative to latest follow-up were documented for Constant-Murley Score (34.9 pts to 74.43 pts, P < .001) and active range of motion (abduction 72° to 130°, flexion 36° to 138°, and external rotation 16°to 28°). There was one complete loosening of the humeral component without reoperation. Radiolucency lines were observed in anteroposterior or axial radiographs at the humeral component in 23% of the cases, most of them in anteroposterior view at the calcar region. Radiolucency line findings did not affect clinical outcomes. Major complications or revisions did not occur so far. CONCLUSION: At short-term follow-up, stemless reverse shoulder systems show comparable clinical and radiological outcomes compared to stemmed reverse implants in the literature.

ABSTRACT

BACKGROUND: While supraspinatus atrophy can be described according to the system of Zanetti or Thomazeau there is still a lack of characterization of isolated subscapularis muscle atrophy. The aim of this study was to describe patterns of muscle atrophy following repair of isolated subscapularis (SSC) tendon. METHODS: Forty-nine control shoulder MRI scans, without rotator cuff pathology, atrophy or fatty infiltration, were prospectively evaluated and subscapularis diameters as well as cross sectional areas (complete and upper half) were assessed in a standardized oblique sagittal plane. Calculation of the ratio between the upper half of the cross sectional area (CSA) and the total CSA was performed. Eleven MRI scans of patients with subscapularis atrophy following isolated subscapularis tendon tears were analysed and cross sectional area ratio (upper half /total) determined. To guarantee reliable measurement of the CSA and its ratio, bony landmarks were also defined. All parameters were statistically compared for inter-rater reliability, reproducibility and capacity to quantify subscapularis atrophy. RESULTS: The mean age in the control group was 49.7 years (± 15.0). The mean cross sectional area (CSA) was 2367.0 mm2 (± 741.4) for the complete subscapularis muscle and 1048.2 mm2 (± 313.3) for the upper half, giving a mean ratio of 0.446 (± 0.046). In the subscapularis repair group the mean age was 56.7 years (± 9.3). With a mean cross sectional area of 1554.7 mm2 (± 419.9) for the complete and of 422.9 mm2 (± 173.6) for the upper half of the subscapularis muscle, giving a mean CSA ratio of 0.269 (± 0.065) which was seen to be significantly lower than that of the control group (p < 0.05). CONCLUSION: Analysis of typical atrophy patterns of the subscapularis muscle demonstrates that the CSA ratio represents a reliable and reproducible assessment tool in quantifying subscapularis atrophy. We propose the classification of subscapularis atrophy as Stage I (mild atrophy) in case of reduction of the cross sectional area ratio < 0.4, Stage II (moderate atrophy) in case of < 0.35 and Stage III (severe atrophy) if < 0.3.

ABSTRACT

PURPOSE: Management of the subscapularis tendon during anatomic total shoulder arthroplasty (TSA) remains controversial. In our unit, subscapularis tenotomy is the preferred technique; however, the potential for tendon gapping and failure is recognised. The purpose of this study is to describe and provide early clinical results of a novel, laterally based V-shaped tenotomy (VT) technique hypothesised to provide greater initial repair strength and resistance to gapping than a transverse tenotomy (TT), with both clinically and radiologically satisfactory post-operative tendon healing and function. METHODS: A retrospective study of patients who underwent primary TSA with VT over a three year period was performed using shoulder and subscapularis-specific outcome scores, radiographs, and ultrasound. A separate cohort of patients who underwent TSA using a subscapularis sparing approach was also reviewed to provide comparative clinical outcomes of a group with TSA and an un-violated subscapularis. RESULTS: Eighteen patients were reviewed at mean 30.4 months (± 11.7). Constant (78.2 ± 12.3), UCLA (8.4 ± 1.5), pain VAS (2.3 ± 2.8), and strength in internal rotation were no different from the comparison group. Likewise, neither were the clinical outcomes of range-of-motion, belly-press, lift-off, and shirt-tuck tests. One patient (5.5%) was found to have a failed subscapularis repair on ultrasound. CONCLUSION: VT during TSA appears to provide healing rates at least equal to those reported for TT, and not dissimilar from those of lesser tuberosity osteotomy. Clinical outcomes are comparable to reported results in the literature for alternative techniques, and not different from those observed here in a comparison cohort with TSA performed without violating the subscapularis tendon. VT therefore potentially offers a more effective and secure tendon repair than a traditional TT, with at least comparable clinical outcomes.

ABSTRACT

BACKGROUND: Anterior shoulder instability is a debilitating condition that can require stabilization via a Latarjet procedure. PURPOSE: The aim of this study was to characterize the histological composition of the articular-sided surface of the coracoid bone graft after Latarjet procedure. Specific features of cells isolated from the coracoid and graft tissues were assessed. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Tissue samples were harvested from 9 consecutive patients undergoing arthroscopic debridement and screw removal after arthroscopic or open Latarjet procedure. Tissues were processed histologically. In 2 patients, the samples were analyzed to assess specific cellular properties. RESULTS: Safranin O staining indicated that glenoid tissues contained variable amounts of glycosaminoglycan (GAG) and round chondrocytic cells mainly organized in clusters. Graft tissues contained less GAG and were more cellular but were not organized in clusters and had variable morphological features. An association appeared to exist between the cartilage quality of glenoid tissues and that of the graft tissues. Cells isolated from glenoid and graft tissues exhibited similar proliferation capacity. CONCLUSION: The results of our analysis show that cells located at the articular-sided surface of transferred coracoid grafts demonstrate fibrocartilaginous properties and may have the capacity for chondral proliferation. Further studies are needed to confirm this observation and future application.

ABSTRACT

BACKGROUND: Proximal humeral fractures (PHFs) are the third most common fracture in older patients. The purpose of the study was to prospectively evaluate the outcomes of PHF fixation with a locking blade nail (LBN) or locking plate (PHILOS) osteosynthesis in a homogeneous elderly patient population. METHODS: Inclusion criteria were an age > 60 years and the capacity to give informed consent. Patients with isolated tuberosity fractures, previous trauma or surgery, advanced osteoarthritis, fracture dislocation, pathological fractures, open fractures, neurological disorders, full-thickness rotator cuff tears, fracture line at the nail entry point or severely reduced bone quality intra-operatively were excluded. Eighty one patients with PHFs were randomised to treatment using LBN or PHILOS. Outcome measures comprised Constant score, age and gender adjusted Constant score, DASH score, VAS for pain, subjective overall condition of the shoulder (1-6) and active shoulder range-of-motion in flexion and abduction. Plain radiographs were obtained in two planes. All data were collected by an independent observer at 3, 6 and 12 months postoperatively. RESULTS: Thirteen patients were excluded intra-operatively due to rotator cuff tears, fracture morphology or poor bone-quality. Of the remaining 68 patients, 27 in the LBN and 28 in the PHILOS group completed the full follow-up. Mean age at surgery was 75.6 years and the majority of PHFs were three-part fractures (49 patients). Baseline demographics between groups were comparable. All outcome measures improved between assessments (p < 0.001). The LBN group showed improved DASH scores as compared to PHILOS at 12 months (p = 0.042) with fewer incidences of secondary loss of reduction and screw cut-out (p = 0.039). A total of 29 complications (in 23 patients) were recorded, 13 complications (in 12 patients) in the LBN group and 16 complications (in 11 patients) in the PHILOS group (p = 0.941). No significant inter-group difference was observed for any other outcome measures, nor was fracture morphology seen to be associated with clinical outcome or complication rate. CONCLUSIONS: At short-term follow-up, LBN osteosynthesis yielded similar outcomes and complication rates to PHILOS plate fracture fixation in an elderly patient population, though with a significantly lower rate of secondary loss of reduction and screw cut-out. REGISTRATION TRIAL: No. DRKS00015245 at Deutsches Register Klinischer Studien, registered: 22.08.2018, retrospectively registered.

ABSTRACT

Distal humerus fractures show increasing incidence with age. Due to preexisting osteoporosis, the surgeon is regularly confronted with complex comminuted intraarticular fractures. The maintenance of autonomy in daily life and avoidance of permanent care dependency is a dogma in the care of geriatric patients. Accordingly, a stable post-operative situation that allows early functional post-operative treatment is mandatory, especially in the elderly patient. Open reduction and stable internal fixation using double plate osteosynthesis are the current osteosynthetic standard of treatment. Modern precontoured systems with angular stability facilitate stable fixation and reduce surgery time. However, complication rates are high, despite the good functional outcomes in the few available studies which use modern plate systems in a geriatric patient population. Due to the high rate of primary stability, elbow arthroplasty has become an established treatment option for complex distal humerus fractures in elderly patients. Consequently arthroplasty registry data report a growing number of elbow replacements for fracture in recent decades. The standard implant design in the fractures in geriatric patients is the cemented "semi-constrained" total elbow arthroplasty. The disadvantages of total elbow replacement are the lifelong stringent weight restriction patients must adhere to, as well as potential long-term complications associated with arthroplasty, such as aseptic loosening and periprosthetic fractures. Comparative studies with short- and medium-term follow-up show overall comparable functional results for elbow arthroplasty and double plate osteosynthesis, with fewer complications and revisions as well as a shorter duration of surgery within the arthroplasty group. However, long-term outcome studies are necessary to identify potential long-term complications associated with arthroplasty and are pending. Therefore, in reconstruction of fractures of the distal humerus which allow stable fixation and early functional post-operative treatment, open reduction and double plate internal fixation with modern locking plate systems remains the gold standard even for geriatric patients.

ABSTRACT

PURPOSE: To analyze and compare patient expectations of primary and revision shoulder stabilization and to assess the factors associated with patients' expectations. METHODS: Pre-operative patient expectations after shoulder instability repair were prospectively assessed using a self-designed questionnaire. The survey included questions on the expected level and type of return to sports, instability, pain, risk of osteoarthritis, and overall shoulder condition. RESULTS: One-hundred and forty-five patients (99 primary; 46 revision repair) were included. A return to sport at the same level with slight to no restrictions was expected in 95%, a return to high-risk activities in 34%, to moderate in 58%, and to low-risk activities in 9%. No pain [instability] independent of the activity level was expected by 71% [79%] and occasional pain [instability] during contact and overhead activities by 25% [19%]. 61% expected to have no risk of glenohumeral osteoarthritis, 37% a slight, and 2% a significant risk. The overall expectation for the post-operative shoulder was indicated to be normal or nearly normal in 99% of patients. The revision group did not differ from the primary repair group in any variable. High pre-operative sport performance was positively correlated with post-operative sport expectations. The number of dislocations, the duration of instability, and the subjective instability level were negatively correlated with return to sport expectations. CONCLUSION: Patient expectations for primary and revision shoulder instability repair are high. Realistic patient expectations regarding the surgical procedure are necessary to avoid low patient satisfaction, especially in pre-operatively highly active and demanding athletes. The surgeon must not solely base the treatment on the pathology and possible risk factors for failure but should also take the individual expectation of the patient into account. LEVEL OF EVIDENCE: III.

ABSTRACT

PURPOSE: To prospectively monitor health-related quality of life and return to work after arthroscopic anterior cruciate ligament (ACL) reconstruction in patients with isolated ACL tears. METHODS: Sixty consecutive patients with isolated ACL tears who underwent arthroscopic ACL reconstruction were prospectively monitored using the "Questions on Life Satisfaction Modules" (FLZM) and "Short-Form 12 (SF-12)" quality-of-life outcome measures. The Lysholm score and Tegner activity index were used as functional outcome measures. Additionally, return to work (months) together with level of physical workload was analysed. Outcome measures were assessed the day before surgery and at 6, 12 weeks and 6, 12, and 24 months post-operatively. Quality-of-life outcomes were correlated with functional outcome scores. RESULTS: Satisfaction with health (FLZM) significantly improved within the first 2 years (p < 0.05), and the physical component scale (SF12) showed a significantly higher score after 3, 6, 12 and 24 months as compared with preoperative values (p < 0.05). "General life satisfaction (FLZM)" was initially decreased at 6 weeks (p < 0.05) but increased during the further follow-up period, reaching a score not significantly different from preoperative values. Mean Lysholm score improved from 66 preoperatively to 89 post-operatively (p < 0.05) and the median Tegner activity index improved from four to six points (p < 0.05) at final follow-up. Mean time to return to work was 7 weeks (range 1-34 weeks), and it strongly depended on physical workload. A positive correlation between quality of life and functional outcome (Lysholm score) was observed. CONCLUSION: General life satisfaction is impaired during the early post-operative course, but returns to preoperative values after 2 years. Satisfaction with health reaches higher values after 6, 12 and 24 months post-operatively, and the SF-12 physical component scale was seen to improve during the follow-up period. Improved functional outcomes were observed to correlate with quality-of-life measurements. Thus, patients can preoperatively be informed that they will benefit from ACL reconstruction in terms of an improved knee function and satisfaction with health. Heavy physical workload must be considered as a risk factor for prolonged time lost to return to work. These patients have to be identified and informed about realistic expectations.

ABSTRACT

BACKGROUND: The glenoid track concept describes the dynamic interaction of bipolar bone loss in anterior glenohumeral instability. Initial studies have successfully demonstrated this concept's application in clinical populations. In clinical practice, the Latarjet procedure is commonly the preferred treatment in addressing "off-track" Hill-Sachs lesions. The effectiveness of this procedure in restoring such lesions to an "on-track" state, however, has not yet been evaluated or described in the literature. HYPOTHESIS: The Latarjet procedure would transform "off-track" Hill-Sachs lesions to "on-track" lesions. Lesions would remain "on-track" during follow-up, despite glenoid remodeling. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients with "off-track" Hill-Sachs lesions treated with the arthroscopic Latarjet procedure between March 2013 and May 2014 were included. Glenoid track and coracoid graft contact surface area measurements using 3-dimensional computed tomography (3D-CT) were performed preoperatively and at 6-week, 6-month, and at least 12-month (final) follow-up. The mean final follow-up was 23 months. The glenoid diameter, as a percentage of the native glenoid, was also calculated from this imaging. RESULTS: Twenty-six patients met the inclusion criteria. 3D-CT scans were available for all patients preoperatively and postoperatively, with 21 patients (81%) undergoing 6-month follow-up CT and 19 patients (73%) undergoing final follow-up CT. Hill-Sachs lesions remained "on-track" at all follow-up time points. The mean glenoid diameter changed significantly from 84.6% preoperatively to 122.8% at 6 weeks ( P < .001) and from 120.5% at 6 months to 113.9% at final follow-up ( P = .005). This was also reflected in significant remodeling seen in the coracoid graft articular contact area (6 weeks to 6 months, P = .024; 6 months to final follow-up, P = .002). This persisting glenoid arc enlargement at final follow-up avoided "off-track" Hill-Sachs lesions in 6 of 19 patients (32%), which would otherwise have occurred had the coracoid graft remodeled to native glenoid dimensions. CONCLUSION: The Latarjet procedure provides an effective treatment for "off-track" engaging Hill-Sachs lesions, despite an evident glenoid remodeling process. At a mean of 23 months postoperatively, a mean persisting enlargement of the glenoid arc of 14% beyond native dimensions remained, avoiding a recurrent "off-track" lesion in 32% of patients, which would otherwise have occurred with complete remodeling.

ABSTRACT

BACKGROUND: Fractures of the humeral greater tuberosity (GT) are a frequent injury progressively treated with arthroscopic suture anchor repair. Yet, no biomechanical study has been performed comparing fixation strength of arthroscopic single- (SR) vs. double row (DR) fixation. METHODS: Standardized fractures of the greater tuberosity were created in 12 fresh frozen proximal humeri. After random assignation to the SR or DR group the fixed humeri were tested applying cyclic loading to the supraspinatus and infraspinatus tendon. Load to failure and fragment displacement were assessed by means of an electrodynamic material testing machine using an optical tracking system. RESULTS: Load to failure values were higher in the DR group (649 N; ±176) than in the SR group (490 N; ±145) however without statistical significance (p = .12). In greater tuberosity displacement of 3-5 mm surgical treatment is recommended. The fixing constructs in this study did not reach displacement landmarks of 3 or 5 mm before construct failure as shown in previous studies. Thus the applied traction force (N) at 1 mm displacement was analyzed. In the SR group the load at 1 mm displacement was 277 N; ±46 compared to 260 N; ±62 in the DR group (p = .65). CONCLUSION: The results suggest that both techniques are viable options for refixation of greater tuberosity fractures. LEVEL OF EVIDENCE: Laboratory study.

ABSTRACT

PURPOSE: To report general life and health satisfaction after arthroscopic Bankart repair in patients with post-traumatic recurrent anterior glenohumeral instability and to investigate postoperative time lost to return to work at 2-year follow-up. METHODS: Between 2011 and 2013 patients treated with arthroscopic Bankart repair in the beach chair position for acute shoulder instability were included in this study. Questions on Life Satisfaction Modules (FLZM) and the Short Form 12 (SF-12) were used as quality-of-life outcome scales. Oxford Instability Score (OIS), Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), and self-reported American Shoulder and Elbow Surgeons (ASES) shoulder index were used as functional outcome scales. Return to work (months) was monitored and analyzed depending on physical workload. Data were assessed the day before surgery and prospectively monitored until 24 months postoperatively. Quality-of-life outcome was correlated with functional shoulder outcome and compared with normative age-adjusted data. Paired t-test, Wilcoxon test, Mann-Whitney U-Test, and Spearman's correlation coefficient were used for statistical analysis. RESULTS: Fifty-three patients were prospectively included. The mean age at surgery was 29.4 years. Satisfaction with general life and satisfaction with health (FLZM) as well as physical component scale (SF-12) improved significantly to values above normative data within 6 to 12 months after surgery (each P < .001). OIS, QuickDASH, and ASES improved significantly from baseline until 24 months after surgery (each P < .001). For ASES, improvement above minimal clinically important difference was shown. There was a positive correlation between quality of life and functional outcome scores (P < .05; rho, 0.3-0.4). Mean time to return to work was 2 months (range, 0-10; standard deviation, 1.9), with significantly longer time intervals observed in patients with heavy physical workload (3.1 months; range, 0 to 10; standard deviation, 2.4; P = .002). CONCLUSIONS: Following arthroscopic Bankart repair, quality of life was impaired during early course after surgery and increased significantly above preoperative levels within 6 to 12 months after the procedure. A steady state of excellent quality-of-life and functional outcomes was noted after 12 months of follow-up. Quality-of-life outcome scales correlated significantly with the functional outcome. Heavy physical workload must be considered as a risk factor for prolonged time lost to return to work. LEVEL OF EVIDENCE: Level III, prospective noncomparative therapeutic case series.

ABSTRACT

INTRODUCTION: According to the expected demographical changes, the number of elderly trauma patients will increase exponentially over the next decades. Different models of an interdisciplinary orthogeriatric care have been developed. But there is only limited evaluation of their benefit without clear and evidence-based results. In 2011, we monitored the results of our orthogeriatric combined management by conducting a 1-year follow-up. METHODS: We treated 231 patients presenting a proximal femoral fracture on our orthogeriatric ward. We obtained the epidemiological data and the geriatric assessments from all these patients. One year after discharge, we sent them a written questionnaire. Primary end points were the mortality and the functional outcome, measured by Barthel score, the requirement of care, and the residential status. RESULTS: One hundred sixty-seven (72%) of the 231 patients completed the follow-up. The average age at admission was 81.5 years (70-99 years). The mortality rate was 2.4% during hospital stay and 31.4% after 1 year. The average Barthel score was 44 points at the time of admission, 55 points at discharge, and 72 points after 1 year. Forty-five percent of the patients were in requirement of care at the time of their admission. At the 1-year follow-up, 63% of the patients had some form of care, thus showing an increase of 18%. At the moment of the fracture, 77% of the patients were living in their own home and 23% in a nursing home. After 1 year, the surviving patients show nearly unchanged conditions (75% own home vs 25% nursing home). Eighty-six percent of the patients coming from their own home were able to continue living there independently. CONCLUSION: The orthogeriatric care is successful in reducing the short-time mortality without showing any effect on 1-year mortality. But the surviving patients seem to benefit from an improved functional outcome.

ABSTRACT

BACKGROUND: Although some reports have presented short- to midterm results after arthroscopic repair of isolated subscapularis (SSC) tendon tears, long-term evaluation is still lacking. HYPOTHESIS: Long-term results after arthroscopic repair of isolated SSC tears are comparable with the functional and radiological short- to midterm outcomes described in the literature. STUDY DESIGN: Case series, Level of evidence, 4. METHODS: This study assessed 17 patients (5 females and 12 males; mean age, 45.6 years) with isolated SSC tears (Fox and Romeo classification types 2-4) who underwent all-arthroscopic suture anchor repair. The mean interval from symptom onset to the time of surgery was 5.3 months in 16 patients (94.1%). One patient (5.9%) was symptomatic for a prolonged period (104 months) before surgery. All patients were assessed with a clinical examination preoperatively. SSC function was investigated using specific clinical tests and common scoring systems, including Constant, American Shoulder and Elbow Surgeons (ASES), Disabilities of the Arm, Shoulder and Hand (DASH), and Simple Shoulder Test (SST) scores. At follow-up, muscular strength was evaluated using an electronic force-measuring plate. Structural integrity of the repair was assessed using magnetic resonance imaging (MRI). RESULTS: At a mean follow-up of 98.4 ± 19.9 months, the mean Constant score improved from 47.8 preoperatively to 74.2 postoperatively ( P = .001). Higher Constant ( P = .010) and ASES ( P = .001) scores were significantly associated with a shorter time from symptom onset to surgery. The size of the SSC lesion did not correlate with any clinical score outcome ( P = .476, .449, .985, and .823 for Constant, ASES, DASH, and SST scores, respectively). Three patients (17.6%) had persistent positive clinical test results (belly-press/lift-off). Compared with the uninjured contralateral side, SSC strength was significantly reduced in the belly-press position ( P = .031), although active internal ( P = .085) and external ( P = .093) rotation was not affected. In 1 patient, a rerupture was detected by MRI. Six patients had cranial SSC atrophy. Overall, 88.2% of patients were "very satisfied" or "satisfied" with their results. CONCLUSION: Arthroscopic repair of isolated SSC tears results in significant clinical improvements and enduring tendon integrity, although SSC strength remains reduced in the long term. Early surgical treatment seems to be a relevant factor allowing good shoulder function.

ABSTRACT

The subscapularis is the largest and strongest muscle of the rotator cuff, and it plays an essential role in global shoulder function. Beyond its primary function as an internal rotator, the subscapularis also acts to pull the humeral head posteriorly on the glenoid and is an important dynamic and static anterior stabilizer of the glenohumeral joint. In comparison with tears of the tendons of the rest of the rotator cuff, isolated tears of the subscapularis have a tendency for both early retraction and fatty infiltration. Consequently, full-thickness tears of the subscapularis tendon generally require surgical management. Arthroscopic suture-anchor repair allows anatomic reconstruction of the anterior aspect of the rotator cuff, with all of the benefits of arthroscopic surgery. The principal steps of this procedure include (1) verifying the subscapularis tear and identifying any concomitant lesions during diagnostic arthroscopy, (2) exposing the subscapularis tendon, (3) releasing tendon adhesions and so enabling anatomic reduction, (4) placing suture anchors at the anatomic subscapularis footprint on the lesser tuberosity and anatomically repairing the subscapularis tendon to its anatomic insertion, and (5) performing biceps tenodesis or tenotomy, if indicated. Postoperatively, patients with an isolated subscapularis tear are managed with immobilization in a sling for 6 weeks, while those with combined anterosuperior rotator cuff tears are managed with an abduction pillow. Arthroscopic subscapularis reconstruction provides a good structural repair, substantially restores shoulder mobility and strength, reduces pain, and results in high levels of patient satisfaction and return of shoulder function as measured by functional outcome scores.

ABSTRACT

BACKGROUND: Anterior-inferior shoulder instability is a common injury in young patients, particularly those practicing overhead-throwing sports. Long-term results after open procedures are well studied and evaluated. However, the long-term results after arthroscopic repair and risk factors of recurrence require further assessment. HYPOTHESIS: Arthroscopic Bankart repair results are comparable with those of open repair as described in the literature. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 180 shoulders with anterior-inferior shoulder instability were stabilized arthroscopically, met the inclusion criteria and the patients were able to be contacted at a minimum of 10-year follow-up. Of these patients, 143 agreed to participate in the study. Assessment was performed clinically in 104 patients using the American Shoulder and Elbow Surgeons score, Constant score, American Academy of Orthopaedic Surgeons score, Rowe score, and the Dawson 12-item questionnaire. The Samilson-Prieto score was used to assess degenerative arthropathy in radiographs available for 100 shoulders. Additionally, 15 patients participated through a specific questionnaire and 24 patients through a telephone survey. RESULTS: The overall redislocation rate was 18.18%. Redislocation rates for the different types of fixation devices were as follows: FASTak/Bio-FASTak, 15.1% (17/112); SureTac, 26.3% (5/19); and Panalok, 33.3% (4/12). Concomitant superior labral anterior-posterior repair had no effect on clinical outcome. Redislocation rate was significantly affected by the patient's age and duration of postoperative rehabilitation. Redislocation rate tended to be higher if there had been more than 1 dislocation preoperatively ( P = .098). Severe dislocation arthropathy was observed in 12% of patients, and degenerative changes were significantly correlated with the number of preoperative dislocations, patient age, and number of anchors. The patient satisfaction rate was 92.3%, and return to the preinjury sport level was possible in 49.5%. CONCLUSION: Clinical outcome at a mean follow-up of 13 years after arthroscopic repair of anterior-inferior shoulder instability is comparable with the reported results of open Bankart repair in the literature and allows management of concomitant lesions arthroscopically. Modifiable risk factors of postoperative redislocation and arthropathy must be considered. Stabilization after the first-time dislocation achieves better clinical and radiological outcomes than after multiple dislocations.

ABSTRACT

INTRODUCTION: The purpose of this study was to compare the outcome after arthroscopic antero-inferior shoulder stabilization with and without using a 5:30 o'clock portal. MATERIALS AND METHODS: Sixty-two patients [age (mean ± SD), 28.05 ± 8.25 years] with a mean follow-up of 15.23 ± 5.02 months were included in this study. Thirty-one patients underwent arthroscopic antero-inferior shoulder stabilization using the 5:30 o'clock portal in center A (group I) and were compared to 31 matched patients managed with the 3 o'clock portal in center B (group II). Physical examination, standard shoulder scores, ultrasound assessment and subscapularis strength measurement were used to evaluate postoperative shoulder function. RESULTS: Good to excellent results were seen in both groups. No significant differences were seen when comparing ASES, Constant and Rowe Score of both groups. Patients of group II achieved a significant higher score in the SST than patients of group I. (p < 0.05) Patients of group I had a significantly lesser loss of passive external rotation in 0° and 90° of abduction. (p = 0.04; p = 0.056) Ultrasound evaluation and strength measurement showed no significant differences in subscapularis muscle integrity or function neither between the involved and uninvolved shoulder nor between both groups. CONCLUSION: Arthroscopic anterior-inferior shoulder stabilization results in excellent clinical results. When considering portal placement, the deep trans-subscapularis portal allows a more precise suture anchor placement at the inferior glenoid rim and capsular shift with a significant improved external rotation but does not negatively affect the subscapularis function in terms of internal rotation strength or structural integrity. LEVEL OF EVIDENCE: III.

ABSTRACT

The total knee arthroplasty (TKA) is the gold standard for patients with an advanced symptomatic gonarthrosis. However, there are very few publications dealing with the primary TKA for patients with a proximal tibia fracture. In our retrospective study we evaluated 30 patients treated with a TKA for a proximal tibia fracture in our institution between 01/2008 and 12/2014. We collected the following statistical data from each patient: age, classification of the fracture (AO-classification), type of prosthesis used, length of the operation and hospitalization, and complications during the follow-up. We used the Knee Society Score (KSS) and the WOMAC score to evaluate the function. The Knee Society Score showed an average "general knee score" (KSS1) of 81.1 points and an average "functional knee score" (KSS2) of 74.5 points. The average WOMAC score was 78.6 points. Immediate postoperative mobilization with the possibility of a full-weight bearing is of crucial importance for the geriatric patients to maintain the mobility they had prior to the operation and reduce medical complications. Because of these advantages, the primary TKA seems to be a promising alternative to the ORIF of a proximal tibia fracture in the orthogeriatric patient.
