AbstractPatient activity level may be an important prognostic variable relating to outcome in patients with shoulder disorders. The purpose of this cross‐sectional study was to test the hypothesis that a shoulder activity scale will detect differences in shoulder activity based on the patient diagnosis and age. A total of 157 patients of four academic orthopedic surgeons with a diagnosis of rotator cuff disease (86), glenohumeral instability (31) or osteoarthritis (40) were asked to fill out a previously validated shoulder activity scale and the ASES shoulder questionnaire. The patient's diagnosis, gender and age were recorded. The activity level was significantly higher in patients with instability than in patients with rotator cuff disease or osteoarthritis. Patients with rotator cuff disease were significantly more active than patients with osteoarthritis. Linear regression of activity level on patient age and diagnosis demonstrated a statistically significant relationship between activity level and both independent variables. Diagnosis influenced activity level independent of age. This is the first study to document diagnosis‐based differences in the shoulder activity level of patients with different shoulder disorders. Shoulder activity level should be evaluated as a prognostic variable in studies of patients with shoulder disorders that may predict outcome and guide treatment in these patients.

AbstractWhile it is generally accepted that most partial and isolated medial collateral ligament (MCL) injuries can be treated non‐operatively, ideal treatment of the MCL in multi‐ligament knee injuries remains controversial. High failure rates with repair of the posterolateral corner in the multi‐ligament injured knee have been recently reported, favoring reconstruction instead. The same maybe true for MCL injuries, however evidence‐based treatment recommendations are lacking in the current orthopedic literature. The purpose of this study was to perform an evidence‐based systematic review of the operative management (repair and/or reconstruction) of the MCL in the setting of multi‐ligament knee injuries. A comprehensive search of MEDLINE and the Cochrane databases for all relevant articles published in English from 1978 to 2008 on the outcomes of surgical management (repair and/or reconstruction) of the MCL in the setting of combined ligament injuries was performed. Inclusion criteria included articles published in (1) English, (2) on human subjects, (3) between the years of 1978 and 2008, (4) had minimum 12‐month follow‐up, with a mean of at least 24 months, (5) on surgical management of MCL injuries, (6) associated with multi‐ligament injuries (three or more ligaments) and/or knee dislocation, and (7) reported objective outcome data on the respective patient cohorts. Exclusion criteria consisted of technique papers, case reports, studies that included fractures associated with MCL injury and those that included pediatric patients. The review identified eight relevant studies. Five articles focused on MCL repair, while three articles focused on MCL reconstruction. No prospective studies compared MCL repair or reconstruction with non‐operative treatment or directly compared MCL reconstruction with MCL repair. Currently there is a paucity of objective data on the outcomes regarding surgical management of MCL tears in the combined ligament injured knee. This systematic review demonstrated satisfactory results in both repair and reconstruction groups. Future objective outcome‐based studies as well as comparative studies are needed to further evaluate the optimal treatment modality before evidence‐based recommendations can be made. Therefore, individual treatment decisions for each patient should be based on the characteristics and nature of the injury.

Purpose The purpose of this systematic review was to address the treatment of multiligament knee injuries, specifically ( 1 ) surgical versus nonoperative treatment, ( 2 ) repair versus reconstruction of injured ligamentous structures, and ( 3 ) early versus late surgery of damaged ligaments. Methods Two independent reviewers performed a search on PubMed from 1966 to August 2007 using the terms “knee dislocation,” “multiple ligament–injured knee,” and “multiligament knee reconstruction.” Study inclusion criteria were ( 1 ) levels I to IV evidence, ( 2 ) “multiligament” defined as disruption of at least 2 of the 4 major knee ligaments, ( 3 ) measures of functional and clinical outcome, and ( 4 ) minimum of 12 months' follow‐up, with a mean of at least 24 months. Results Four studies compared surgical treatment with nonoperative treatment. There was a higher percentage of excellent/good International Knee Documentation Committee (IKDC) scores (58% v 20%) in surgically treated patients, as well as higher rates for return to work (72% v 52%) and return to full sport (29% v 10%). Two studies compared repair with reconstruction of damaged structures, with similar mean Lysholm scores (88 v 87) and excellent/good IKDC scores (51% v 48%). However, repair of the posterolateral corner had a higher failure rate (37% v 9%). Similarly, repair of the cruciates yielded decreased stability and range of motion and a lower return to preinjury activity levels (0% v 33%). There were 5 studies comparing early surgery (≤3 weeks) with late surgery. Early treatment resulted in higher mean Lysholm scores (90 v 82) and a higher percentage of excellent/good IKDC scores (47% v 31%), as well as higher sports activity scores (89 v 69) on the Knee Outcome Survey. Conclusions Our review suggests that early operative treatment of the multiligament‐injured knee yields improved functional and clinical outcomes compared with nonoperative management or delayed surgery. Repair of the posterolateral corner may yield higher revision rates compared with reconstruction.

Purpose The purpose of this study was to investigate the functional and clinical outcomes of a consecutive series of patients who underwent fibular collateral ligament (FCL) and posterolateral corner (PLC) reconstruction by use of a single Achilles tendon allograft construct. Methods Patients were identified through prospective sports medicine databases at 2 academic institutions. Only patients who had undergone FCL and PLC reconstruction (as opposed to repair) were included. All patients followed a standard postoperative rehabilitation protocol. Various patterns of combined ligament injuries were included and divided into 2 groups (2 ligament v multiligament). Functional and clinical outcomes were assessed by clinical examination, Lysholm scores, and International Knee Documentation Committee subjective scores. Statistical analysis was performed by use of Wilcoxon paired rank‐sum tests and multivariate regression. Results We identified 16 knees in 16 patients, with a minimum of 2 years' follow‐up. There were 13 men and 3 women. The mean age was 30 years (range, 19 to 61 years). The mean length of clinical follow‐up was 30 months (range, 24 to 75 months). The mean International Knee Documentation Committee subjective scores were 80 points and 80 points ( P = .79) in the 2‐ligament and multiligament groups, respectively, and the mean Lysholm scores were 90 points and 89 points ( P = .96), respectively. Age ( P = .41), gender ( P = .84), and interval between injury and surgery ( P = .72) did not affect the clinical and functional outcomes between the 2 groups. Arthrofibrosis requiring manipulation developed in 1 patient. Residual varus laxity (1+) was noted in 4 patients, none of whom displayed functional instability. No patient has required revision reconstruction to date. Conclusions We describe a novel technique that takes into account the main static PLC stabilizers (FCL, popliteofibular ligament, and posterolateral capsule) that has not been previously reported. Our series showed no significant differences in clinical and functional outcomes between 2‐ligament and multiligament PLC‐based reconstructions. However, given the heterogeneity and small sample size of our study group, it is difficult to draw qualitative conclusions. Level of Evidence Level IV, therapeutic case series.

The records of patients aged 50 years or over who underwent primary reconstruction of the anterior cruciate ligament between 1990 and 2002 were reviewed. There were 35 knees in 34 patients that met the inclusion criteria. The mean age of the patients was 57 years (50 to 66) and the mean clinical follow-up was for 72 months (25 to 173). A total of 23 knees were reconstructed with patellar tendon allograft, and 12 with patellar tendon autograft. The mean pre-operative knee extension was 1° (−5° to 10°) and flexion was 129° (125° to 150°) and at follow-up these values were 0° (−5° to 5°) and 135° (120° to 150°), respectively. Pre-operatively there were 31 knees (89%) with a Lachman grade 2+ or 3+. Post-operatively, 33 knees (94%) were Lachman grade 0 or 1+. The mean pre- and post-operative International Knee Documentation Committee scores were 39 (23 to 72) and 90 (33 to 100) respectively. The mean pre- and post-operative Lysholm scores were 50 (18 to 68) and 92 (28 to 100) respectively and the mean University of California Los Angeles activity scores were 8.5 before injury (4 to 10), 4.3 (3 to 6) after injury and 8.3 (4 to 10) post-operatively. There were three graft failures (8.6%) requiring revision. We conclude that reconstruction of the anterior cruciate ligament in carefully-selected patients aged 50 years or over can achieve similar results to those in younger patients, with no increased risk of complications.
