Meniscal Radial Tears Repaired with All-Inside and Inside-Out Techniques Result in Improved Clinical Outcome Scores; However, More Complications are Reported After Inside-Out Repair: A Systematic Review.

PURPOSE: To compare patient-reported outcomes (PROs), failure, and healing rates following all-inside (AI) repair versus inside-out (IO) repair for the treatment of meniscal radial tears. METHODS: A literature search was performed according to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using the Scopus, PubMed, and Embase computerized databases. Level of evidence I through IV human clinical studies evaluating PROs and/or the incidence of failure and healing following AI versus IO repairs for meniscal radial tears were included. Clinical failure was defined by the presence of joint-line tenderness, a positive McMurray test, and mechanical symptoms such as locking, catching, or giving way. Study quality was assessed using the Methodological Index for Non-Randomized Studies (MINORS) criteria and Modified Coleman Methodology Score (MCMS). RESULTS: Ten studies published from 2008 to 2023 comprising 205 patients were identified including 142 patients who underwent AI repair and 63 patients who underwent IO repair for radial meniscus tears. Postoperative Lysholm and Tegner scores ranged from 90.8 to 95.6 and 5.7 to 8.2, respectively, in the AI repair group, compared to 86.9 to 94.2 and 6 to 7.5, respectively, in the IO repair group, and all patients exceeded published values for MCID for the Lysholm score. Clinical failure ranged from 0% to 40% in the AI group and 0% to 62.5% in the IO group. Healing assessments on second-look arthroscopy revealed failure rates ranging from 0% to 13.3% in the AI group and 0% to 39% in the IO group. Complete and partial healing ranged from 28.6% to 92.3% in the AI group and from 25% to 70% in the IO group. Chondral damage on second-look arthroscopy ranged from 0% to 95% in the IO group and 0% to 57.7% in the AI group. Postoperative complications ranged from 0%-2% within the AI group, while no complications were reported in the IO group. No implant-related complications were reported in any study group. CONCLUSION: Both all-inside and inside-out repairs for meniscal radial tears demonstrated improved PROs; however, current literature suggests that the IO technique may have higher failure rates both clinically and on second-look arthroscopy.

Adults Have a Higher Incidence of Discoid Lateral Meniscus Tears Than Children-Adults Tend to Present With Complex Tears, While Horizontal Tear Patterns Are Frequently Encountered in Children: A Systematic Review.

PURPOSE: To systematically review the available literature on patients with discoid lateral meniscus (DLM) with the goal of elucidating the rates and types of meniscal tears, clinical symptoms, treatment strategies, and postoperative clinical and radiographic outcomes in adult patients compared with a pediatric population. METHODS: A literature search was performed using the PubMed, Embase, and Scopus databases from database inception to October 2023 according to the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Level of evidence I through IV human clinical studies evaluating rate and type of meniscal tears, clinical symptoms, patient-reported outcome measures, and postoperative radiographical assessments in patients with DLM were included. Comparisons were made by age younger and older than 16 years. Study quality was assessed using the Methodological Index for Non-Randomized Studies criteria. RESULTS: Thirteen studies comprising 1,772 adult patients (>16 years old) with DLM (n = 1,856 knees) and 8 studies conducted in 304 pediatric patients (≤16 years old, n = 353 knees) were included. The reported mean age ranged from 22.4 to 45 years (mean follow-up, 24-157.5 months) in the adult group and from 5 to 12.9 years (mean follow-up, 37-234 months) in the pediatric DLM group. Among studies that reported on tear patterns, the majority of adult (n = 553; 96.5%) and pediatric (n = 163; 71.8%) patients had tears of the DLM. Complete DLM was the predominant type of DLM in both study groups (range in adults, 49.6% to 88%; range in pediatric patients, 19%-100%) with complex (46.1%; range, 5.3%-100%) and horizontal tears (18.2%; range, 20%-37.5%) being the most frequently described tear patterns in the adult and pediatric DLM groups, respectively. Pain was the predominant reported symptom in both study groups (range in adults, 12.1%-99.3%; range in pediatric patients, 32.4%-100%). Partial meniscectomy was the most frequently reported treatment option conducted in 334 adult knees (39.5%; range, 24.2%-100%) and 66 pediatric knees (63.5%; range, 15%-100%). Overall, improved postoperative clinical outcomes were reported in both study groups; however, radiographic progression of degenerative changes after subtotal meniscectomy was noted. CONCLUSIONS: More adult patients with DLM present with tears in the literature compared with the pediatric population. Complex and horizontal tear patterns are the most frequently reported tears in adult and pediatric patients, respectively. Pain was the most relevant symptom in both study groups. There was generally significant improvement in postoperative clinical outcome scores; partial meniscectomy, however, remains the most frequently reported treatment option and is associated with fewer degenerative changes than in subtotal meniscectomy. LEVEL OF EVIDENCE: Level IV, systematic review of Level I to IV studies.

High-resolution magnetic resonance imaging can predict osteoarthritic progression after medial meniscus posterior root injury: randomized in vivo experimental study in a rabbit model.

IMPORTANCE: The field of meniscal root preservation has undergone significant advancement over the past decades; however, the challenge remains to fully understand whether meniscal root repair can ultimately arrest or delay osteoarthritic changes. OBJECTIVE: To assess longitudinal changes in articular cartilage, subchondral bone, and progression to meniscal extrusion (ME) using high-resolution magnetic resonance imaging (MRI). METHODS: Medial meniscus posterior root tear was surgically induced in 39 New Zealand white rabbits. Animals were randomly assigned into three experimental groups: partial meniscectomy after root tear (PM, n â€‹= â€‹13); root tear left in situ (CT, n â€‹= â€‹13); and transtibial root repair (RR, n â€‹= â€‹13). Contralateral limbs were used as healthy controls. High resolution 4.7 Tesla MRI of the knee joint was performed at baseline, after 2-, and 4-months of post-surgery. Cartilage thickness was calculated in medial and lateral compartments. In addition, the evaluation of ME, subchondral bone edema and healing potential after root repair were assessed too. RESULTS: Progressive cartilage thinning, ME, and subchondral bone edema were evident in all 3 study groups after 4-months of follow-up. The mean cartilage thickness in the PM group was 0.53 â€‹mm (±0.050), 0.57 â€‹mm (±0.05) in the CT group, and 0.60 â€‹mm (±0.08) in the RR group. The PM group exhibited significantly higher cartilage loss when compared to the CT and RR groups (p â€‹< â€‹0.001). Moreover, progressive ME and subchondral bone edema were associated with a more severe cartilage loss at the final follow-up. CONCLUSION: Meniscal root repair did not halt but rather reduced the progression of osteoarthritis (OA). Degenerative changes worsened at a rapid rate in the PM group compared to the RR and CT groups. Early cartilage swelling, persistent subchondral edema, and progressive ME predicted a more severe progression to knee OA in the CT and RR groups. LEVEL OF EVIDENCE: II.

All-Inside and Inside-Out Repair Techniques for Bucket-Handle Meniscus Tears Both Result in Improved Patient Outcomes and a Broad Range of Failure Rates: A Systematic Review.

PURPOSE: To compare patient-reported outcomes, failure rates, risk factors for failure, and complications in patients with bucket-handle meniscus tears (BHMTs) undergoing repair with inside-out (IO) versus all-inside (AI) techniques. METHODS: A literature search was performed using the PubMed, Embase, and Scopus databases from database inception to August 2023 according to the 2020 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The inclusion criteria consisted of Level I to IV clinical studies published in the past 10 years with greater than 2 years of follow-up that evaluated patient-reported outcome scores and/or the incidence of failure after IO or AI repairs for BHMTs. Clinical studies not reporting outcomes or failure rates, older studies using outdated implants, animal studies, reviews, letters to the editor, case reports, cadaveric studies, and articles not written in the English language or with English-language translation were excluded. Study quality was assessed using the Methodological Index for Non-randomized Studies (MINORS) criteria. Outcomes were reported as ranges and qualitatively compared. RESULTS: A total of 16 studies published from 2013 to 2023, consisting of 1,062 patients with BHMTs, were identified. Thirteen studies (14 cohorts, 649 patients) reported on AI repair (mean age range, 23.7-32 years) and 7 studies (7 cohorts, 413 patients) reported on IO repair (mean age range, 16.7-34.6 years). Both groups had improved postoperative Lysholm and Tegner scores. Decreased range of motion was the most commonly reported complication in the AI group (range, 2.6%-4%), whereas adhesions for arthrofibrosis were the most commonly reported complication in the IO group (n = 12; range, 6%-7.9%). The overall reported failure rate ranged from 6.9% to 20.5% within the AI group and from 0% to 20% within the IO group. CONCLUSIONS: AI and IO repair techniques for BHMTs both result in improved Lysholm and Tegner scores. However, broad ranges of failure are reported in the literature, with overall failure rates ranging from 6.9% to 20.5% after AI repair and from 0% to 20% after IO repair. Younger age and isolated medial BHMT repair are the most frequently reported risk factors for the AI technique, whereas postoperative stiffness is the most frequently reported complication after both repair techniques. LEVEL OF EVIDENCE: Level IV, systematic review of Level I to IV studies.

Increased Posterior Tibial Slope Is Associated With Increased Risk of Meniscal Root Tears: A Systematic Review.

BACKGROUND: While increased posterior tibial slope (PTS) is an established risk factor for anterior cruciate ligament tears, the association between tibial slope and meniscal posterior root tears is not well-defined. PURPOSE: To summarize the available literature evaluating the association between PTS and meniscus root injuries compared with patients without root tears. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A literature search was performed using the Scopus, PubMed, and Embase databases. Human clinical studies evaluating the associations between the medial tibial slope (MTS), lateral tibial slope (LTS), lateral-to-medial (L-to-M) slope asymmetry, and the risk of meniscus root tears were included. Patients with medial meniscus posterior root tears (MMPRTs) and lateral meniscus posterior root tears (LMPRTs) were compared with a control group without root injury. Study quality was assessed using the methodological index for non-randomized studies criteria. RESULTS: Ten studies with 1313 patients were included (884 patients with root tears; 429 controls). The LMPRT subgroup (n = 284) had a significantly greater LTS (mean ± SD, 7.3°± 1.5° vs 5.7°± 3.91°; P < .001), MTS (5.26°± 1.2° vs 4.8°± 1.25°; P < .001), and increased L-to-M asymmetry (2.3°± 1.3° vs 0.65°± 0.5°; P < .001) compared with controls. The MMPRT group (n = 600) had significantly increased MTS relative to controls (8.1°± 2.5° vs 4.3°± 0.7°; P < .001). Furthermore, there was a higher incidence of noncontact injuries (79.3%) and concomitant ramp lesions (56%) reported in patients with LMPRT. CONCLUSION: Increased MTS, LTS, and L-to-M slope asymmetry are associated with an increased risk of LMPRTs, while increased MTS is associated with MMPRTs. Surgeons should consider how proximal tibial anatomy increases the risk of meniscus root injury.

Outcomes of Arthroscopic Latarjet as a Revision Surgery After Failed Arthroscopic Bankart Repair.

BACKGROUND: The role of arthroscopic Latarjet as a revision surgery after failed arthroscopic Bankart repair has yet to be established. PURPOSE: To compare clinical outcomes, recurrences, and complication rates of arthroscopic Latarjet as a revision procedure after failed arthroscopic Bankart repair versus arthroscopic Latarjet as a primary procedure. DESIGN: Cohort study; Level of evidence, 3. METHODS: This is a retrospective study of prospectively collected data of patients who were diagnosed with anterior shoulder instability and underwent arthroscopic Latarjet stabilization between 2009 and 2018. Patients were separated into 2 groups depending on whether Latarjet was performed after a previous instability surgery (revision) or as a primary surgery (primary). Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE) were assessed pre- and postoperatively with a minimum 24 months of follow-up. In addition, pre- and postoperative levels of sports activity, dislocations, subluxations, and complications were assessed. RESULTS: A total of 97 patients (n = 62 revision; n = 35 primary), with a mean age of 31.0 ± 8.8 and 29.4 ± 7.6 years old in the revision and primary Latajet group, respectively, met the inclusion criteria. The mean follow-up in the revision group was 32 months (24-53) and 35.5 months (27.7-42.2) in the primary Latarjet group. No significant differences between groups were observed in Rowe score (revision = 91.4, primary = 94.1; P = .223), CMSO score (revision = 90.7, primary = 94; P = .105), and SANE (revision = 85.8, primary = 87.3; P = .683) postoperatively. However, the postoperative difference in the WOSI score between the revision and primary Latarjet groups was nearly significant (510 ± 334 vs 403 ± 343, respectively; P = .05). Four (6.4%) postoperative dislocations were reported in the revision and 1 (2.8%) in the primary Latarjet group (P = .14). Patients in the revision group had a lower return to the previous level of sports participation (P = .008) and decreased external rotation with the arm by the side compared with the primary Latarjet group (P = .000). CONCLUSION: Arthroscopic Latarjet as a revision surgery is a reasonable surgical option in failed Bankart repair cases. The decision to perform arthroscopic Latarjet stabilization as a revision surgery should not be influenced by the potential risk of future complications as it provides comparable clinical outcomes to the primary Latarjet procedure with a low postoperative recurrence rate. However, a decreased level of postoperative sports participation and external rotation with the arm by the side can be expected.

Increased Alpha Angles and Younger Age Increase the Risk of Contralateral Femoral Acetabular Impingement Syndrome Symptom Development and Surgical Intervention: A Systematic Review.

PURPOSE: To identify the preoperative risk factors associated with contralateral symptom development and surgical intervention for patients presenting with unilateral femoral acetabular impingement (FAI) syndrome. METHODS: A literature search was performed using PubMed and Scopus computerized databases according to the 2020 Preferred Reporting Items for Systematic Meta-Analyses guidelines. Studies evaluating preoperative risk factors associated with the contralateral progression of FAI were included. Quality assessment was completed using the Methodological Index for Non-Randomized Studies criteria. RESULTS: A total of 5 studies (n = 1,011 patients; mean age, 29.9 years) published from 2013 to 2022 met the inclusion/exclusion criteria. Mean follow-up ranged from 12 to 132 months. The overall rate of contralateral progression of symptomatic FAI ranged from 32.4% to 81%. Increased alpha angle was frequently reported factor associated with contralateral symptom progression, followed by decreased total arc of rotation, decreased internal rotation, reduced neck-shaft angle, and head-neck offset. The incidence rate of progression to contralateral surgery ranged from 15.7% to 24% of patients. Younger age was frequently reported factor associated with contralateral surgical intervention, followed by male sex, increased level of activity, and increased alpha angle. CONCLUSIONS: Increased alpha angle and younger age were commonly reported risk factors associated with an increased risk of symptom development and surgical progression of contralateral FAI, respectively. The overall rate of contralateral progression of symptomatic FAI and the rate of progression to surgical intervention ranged up to 81% and 24%, respectively. This information may help both patients and surgeons to establish expectations regarding development of contralateral hip symptoms and possible need for surgery. LEVEL OF EVIDENCE: Level III; systematic review of Level II-III studies.

Metaphyseal cones combined with diaphyseal impaction grafting provide good outcomes and survival in a complex revision total knee arthroplasty: a matched comparative analysis.

PURPOSE: To compare clinical and radiological outcomes, implant survivorship at a minimum of 1-year follow-up using metaphyseal trabecular cones with or without impaction grafting in a complex revision TKA. METHODS: A retrospective comparative matched analysis was performed and 15 patients who underwent revision surgery using the combination of porous trabecular metaphyseal cone and diaphyseal impaction grafting (MC-IBG) were matched with a group of 13 patients who also underwent revision surgery using metaphyseal cone (MC) without impaction grafting. All included patients presented severe bone defect (AORI 2,3) and a rotating-hinge prosthesis were implanted. RESULTS: Both groups were comparable regarding the baseline demographic and clinical data. Patients had previously undergone a mean of 4 (range, 2-12) and 3 (range, 2-5) previous procedures in the MC-IBG and MC groups, respectively. The indications for revision were aseptic loosening in 11 (73.3%) and 11 (84.6%) patients; prosthetic joint infection in 4 (26.7%) and 2 (15.4%) in the MC-IBG and MC groups, respectively. There was no significant difference in the mean postoperative Knee Society Score between the study groups (p = 0.806). Overall, 4 patients had further revision. Two patients were revised in the MC-IBG group, one patient for aseptic loosening and the second one after 2 episodes of instability. Two patients in the MC group presented prosthetic joint infection and underwent a two-stage reimplantation. No significant difference was observed between the study groups at comparison (p = 0.92). CONCLUSION: Trabecular metal cones with diaphyseal impaction grafting provide an alternative technique in a complex revision TKA surgery with early clinical and radiographic success.

Meniscus Extrusion, Radial Tears, and Root Tears.

Management of meniscal radial and root tears and extrusion is complex and has changed significantly over recent years. It is important to provide a comprehensive overview of the management of radial and root tears and meniscal extrusion and be aware of the currently available evidence on repair techniques, rehabilitation, and outcomes following radial and root repairs.

Medial Meniscus Posterior Root Repair Reduces but Does Not Avoid Histologic Progression of Osteoarthritis: Randomized In Vivo Experimental Study in a Rabbit Model.

BACKGROUND: The optimal treatment option for meniscus root tears is still challenging, and whether the meniscus root repair ultimately can arrest or delay osteoarthritic changes is still a concern. PURPOSE/HYPOTHESIS: The purpose of this study was 2-fold: (1) to describe and compare histopathologic findings of 3 different therapeutic options for medial meniscus posterior root tear: nonoperative management, partial meniscectomy, and meniscus root repair; and (2) to test the hypothesis that meniscus root tears treated nonoperatively predispose to a lower risk of osteoarthritic progression compared with partial meniscectomy. STUDY DESIGN: Controlled laboratory study. METHODS: Posteromedial meniscus root tears were carried out in 39 New Zealand White rabbits. Animals were randomly assigned into 3 experimental groups: partial meniscectomy after root tear (PM; n = 13), root tears treated conservatively (CT; n = 13), and transtibial root repair (RR; n = 13). Contralateral limbs were used as healthy controls. The animals were euthanized at 16 weeks postoperatively; tissue samples of femoral and tibial articular cartilage were collected and processed for macro- and microscopic assessment to detect signs of early osteoarthritis (OA). Each sample was histopathologically assessed using the Osteoarthritis Research Society International grading and staging system. RESULTS: Osteoarthritic changes were the hallmark in all 3 experimental groups. The RR group had the lowest scores for cartilage damage (mean, 2.5; range, 2-3), and the PM group exhibited higher and more severe signs of OA (mean, 16; range, 9-16) compared with the CT group (mean, 5; range, 4-6). The between-group comparison revealed significant differences, as the PM group showed a significantly higher rate of macro- and microscopic osteoarthritic changes compared with the RR (P < .001) and CT (P < .001) groups. The weightbearing area of the medial femoral condyle was the most severely affected, and tidemark disruption was evident in all tissue samples. CONCLUSION: Meniscus root repair cannot completely arrest the histopathologic progression of knee OA but leads to significantly less severe degenerative changes than partial meniscectomy and nonoperative treatment. Partial meniscectomy leads to the most severe osteoarthritic progression, while stable radial tears left in situ have lower progression compared with partial meniscectomy. CLINICAL RELEVANCE: Histologic assessment is an essential tool and metric for guiding and understanding osteoarthritic features, providing insight into the disease development and progression. This study provides histopathologic evidence on osteoarthritic progression after medial meniscus posterior root repair. This knowledge can help to set more realistic expectations and can lead to the future development of augmented techniques.

Prognostic Factors and Midterm Clinical Outcome of Transtibial Pullout and Partial Meniscectomy for Medial Meniscus Posterior Root Tears in Middle-Aged Patients.

Purpose: The purpose of this study was to compare clinical and radiological outcomes of transtibial pullout technique and partial meniscectomy, and to establish prognostic factors in middle-aged patients with mild knee osteoarthritis. Methods: A comparative case-control analysis was conducted. 65 patients between 40 and 60 years of age were included into two groups: 30 patients who underwent transtibial pullout technique (group 1) and 35 patients who underwent partial meniscectomy (group 2). Mean follow-up was set at 27.2 months. Primary clinical outcomes included Knee injury and Osteoarthritis Outcome Score and Lysholm Knee Questionnare. Preoperative MRI and intraoperative arthroscopic findings were recorded. The correlation between these findings and patient-reported subjective outcome were assessed. Results: The transtibial pullout group exhibited significantly greater improvement in clinical outcomes. A univariate model revealed that the presence of preoperative meniscal extrusion, body mass index (> 30), osteochondral defect, and female gender were predictors of poor clinical outcome. Multivariate regression analysis showed meniscal extrusion and osteochondral defect as significant prognostic factors for both study groups. Conclusion: Medial meniscus root repair leads to significantly improved clinical outcomes compared to partial meniscectomy in middle-aged patients with mild knee osteoarthritis. Presence of meniscal extrusion, osteochondral defect, BMI > 30, and female gender were deemed as predictors of poor postoperative patient-reported outcome. Level of Evidence: III therapeutic case-control study.

Developing an experimental model of early knee osteoarthritis after medial meniscus posterior root release: an in vivo study.

PURPOSE: To develop a predictable and reproducible model of knee osteoarthritis after medial meniscus posterior root release. METHODS: Posteromedial meniscal root tears were created in 12 White New Zealand rabbit knees. The contralateral limbs were used as healthy controls. The animals were euthanized at 16 weeks postoperatively; tissue samples of femoral and tibial articular cartilage were collected and processed for macro and microscopic analyses to detect signs of early degeneration. Clinical evaluation of the weight-bearing status on the affected knee was conducted at 0-, 4-, 8-, and 16-weeks postoperatively. RESULTS: Early and severe osteoarthritic changes were the hallmark and the main findings after 16-weeks post-surgery. Macroscopically, extensive osteoarthritic changes were observed across the femoral condyle and tibial plateau. Microscopic finding included ulcerations, fissures, fibrillations, pitting, and loss of the superficial layer. Cellularity was diminished, the normal pattern of distribution in columns was lost, and subchondral bone exposure was also evident. CONCLUSIONS: This study describes a novel model of knee osteoarthritis that may guide the development of tailored interventions to delay or prevent knee osteoarthritis. This knowledge could shift the current treatment paradigm toward more conservative and knee salvageable treatment options and increase surgeons' awareness of this injury pattern. Such considerations may have a positive impact on clinical decision-making and subsequent patient-reported clinical outcomes. DESIGN: Controlled laboratory study. LEVEL OF EVIDENCE: II.

Outcomes of Arthroscopic Latarjet Procedure for Anterior Glenohumeral Instability in Patients With Epilepsy: A Case-Control Study.

BACKGROUND: Unacceptably high rates of redislocation, reoperation, osteoarthritis, and coracoid nonunion have been reported in patients with a seizure disorder after surgery for shoulder instabilitiy. PURPOSE: To evaluate the objective and subjective functional and radiologic results of the arthroscopic Latarjet procedure for anterior shoulder instability in patients with epilepsy and compare them with the results of patients without epilepsy. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective and comparative case-control analysis of patients operated for shoulder instability with arthroscopic Latarjet was conducted. Nineteen patients (21 unstable shoulders) with a seizure disorder (epilepsy group) were matched with 21 patients without a history of seizure (control group). Demographics, surgical indications, and imaging data were collected. Clinical outcomes at a minimum 2 years of follow-up (range, 2-9 years) postoperatively included Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE). The incidence of complications, recurrent instability, redislocation, revision surgery, repeated seizure(s), and presence of osteoarthritis, coracoid nonunion, and osteolysis were also examined. RESULTS: After a mean follow-up of 4.5 years, no significant differences in functional results were found between patients with and without epilepsy on the average Rowe (P = .917), WOSI (P = .621), CMSO (P = .600), and SANE (P = .859) scores. A total of 5 patients (7 shoulders) continued to have seizures postoperatively, but no seizure-related glenohumeral instability was documented. One dislocation and 1 subluxation were documented while participating in sports in each study group, comprising a recurrence rate of 9.5%, but no significant differences were found at comparison (P = .605). A bone defect did not influence the results, as no significant difference was found between the 2 groups. Osteoarthritic changes of the glenohumeral joint were observed in 5 shoulders (23.8%) in the epilepsy group and in 3 (14.3%) in the control group (P = .451). No case of coracoid nonunion or osteolysis was recorded. There was no statistically significant difference in postoperative athletic activity (P = .660). However, patients with epilepsy had significantly lower pre- and postoperative sports participation (P < .001). CONCLUSION: Arthroscopic Latarjet stabilization can lead to improved functional and subjective outcomes and should be considered in patients with epilepsy with recurrent anterior glenohumeral instability. These results can be achieved regardless of the presence of bone defect and the postoperative control of seizures and are similar to those in patients without epilepsy.

Prognostic factors of trochanteric bursitis in surgical-staged patients: a prospective study.

BACKGROUND: Trochanteric bursitis or greater trochanteric pain syndrome is a common disorder and frequent cause of lateral hip pain. It can lead to severe functional impairment with increase morbidity and poor quality of life.The purpose of the current study was to identify and evaluate relationship between health-related factors, as prognostic indicators, and clinical outcomes. METHODS: A single-centre, prospective study was conducted and 60 patients (62 hips) were included with a minimum 12 months of follow-up. Clinical outcomes were evaluated using Hip Outcome Scale, Single Assessment Numeric Evaluation and Visual Analogue Scale. Radiological assessments and health-related factors were documented in an attempt to understand their validity as predictors of clinical outcomes. Complications and recurrence rates were also analyzed. RESULTS: Univariate model revealed that an increased BMI (p = 0.001; OR = 1.05; 95% CI, 1.02-1.07); number of previous corticosteroid infiltrations (p = 0.001; OR = 1.28, 95% CI, 1.11-1.48); longer time from symptom onset to surgery (p = 0.001; OR = 1.19; 95% CI, 1.12-1.28); smoker status (p = 0.001; OR 11.2; 95% CI, 3.30-44.2); and the presence of prior lumbosacral fusion (LSF) (p = 0.001; OR 13.8; 95% CI, 2.96-101); were prognostic factors predisposing for poor clinical outcomes.Among prognostic health-related factors were medical comorbidities such as emotional distress (p < 0.001; OR 26.1; 95% CI, 5.71-192); fibromyalgia (p = 0.026; OR 3.56; 95% CI, 1.16-11.7); and hyporthyroidism (p = 0.005, OR = 6.55, 95% CI, 1.73-28.7). CONCLUSIONS: Better overall physical function was predicted by lower number of corticosteroid infiltrations, shorter time span from symptom onset to surgery, non-smoker status and the absence of prior lumbosacral fusion. Obesity, smoking, the presence of emotional distress, fibromyalgia and hypothyroidism seem to increase the risk of poor clinical outcomes. A proper selection and/or correction of modifiable prognostic factors could reduce the incidence of endoscopic treatment failure and, as a consequence, improve patient outcomes and quality of life. However, future efforts should focus on experimental and randomised studies to fully determine these associations.

A comparison of the transtibial pullout technique and all-inside meniscal repair in medial meniscus posterior root tear: Prognostic factors and midterm clinical outcomes.

INTRODUCTION: There is a paucity of comparative clinical data between arthroscopic all-inside end-to-end meniscal root suture and transtibial pullout technique in medial meniscus posterior root tears (MMPRT). Therefore, this study aimed to compare treatment failure, mid-term clinical and radiological outcomes of all-inside meniscus root repair versus the transtibial pullout technique and to analyze prognostic factors of postoperative clinical and radiological outcomes. MATERIAL AND METHODS: Forty-four patients were included in two therapeutic group: arthroscopic all-inside meniscal suture (MS: 13 knees) and transtibial pullout technique (TP: 31 knees).Primary clinical outcomes at a minimum of 27.2 months postoperatively included Knee injury and Osteoarthritis Outcome Score (KOOS) and Lysholm Knee Questionnare (LKQ). Radiographic assessment of the knee was performed to determine osteoarthritis severity using the Kellgren-Lawrence (KL) grading system.In addition, pre and postoperative MRI scans and intraoperative arthroscopic findings were recorded and the correlations between these findings, as outcome predictors and postoperative patients reported subjective outcome were assessed. RESULTS: No significant differences in postoperative KOOS and LKQ scores were found between the MS and TP group (p = 0.38 and 0.17, respectively).During follow-up one patients (7.7%) in the MS group and two (6.5%) in the TP group underwent total knee arthroplasty. The difference did not reach the statistical significance (p = 0.88).No differences were observed in postoperative MRI findings such as meniscal extrusion, osteochondral defect, chondromalacia patella, and bone morrow edema (p = 0.25, 0.97, 0.97, and 0.88, respectively).A univariate model revealed that the presence of postoperative meniscal extrusion; osteochondral defect; chondromalacia patella; increased BMI; age (>40 years) and longer time lapse between clinical onset to surgery (>6 months) were predictors of poor clinical outcome. The presence of meniscal extrusion, osteochondral defect and chondropatia patella portended worst postoperative outcomes in a multiple linear regression model. CONCLUSIONS: It can be concluded that both techniques can reach good results when performed properly and if the injury pattern allows meniscal suture may be considered a treatment option for the management of MMPRT in well-selected patients.Patients with increased BMI, preoperative meniscal extrusion, chondromalacia patella, and osteochondral defect were at higher risk of poor clinical outcomes.
