Treatment of post-meniscectomy knee symptoms with medial meniscus replacement results in greater pain reduction and functional improvement than non-surgical care.

PURPOSE: Partial meniscectomy is a common orthopedic procedure intended to improve knee pain and function in patients with irreparable meniscal tears. However, 6-25% of partial meniscectomy patients experience persistent knee pain after surgery. In this randomized controlled trial (RCT) involving subjects with knee pain following partial meniscectomy, it was hypothesized that treatment with a synthetic medial meniscus replacement (MMR) implant provides significantly greater improvements in knee pain and function compared to non-surgical care alone. METHODS: In this prospective, multicenter RCT, subjects with persistent knee pain following one or more previous partial meniscectomies were randomized to receive either MMR or non-surgical care. This analysis evaluated the 1-year outcomes of this 2-year clinical trial. Patient-reported knee pain, function, and quality of life were measured using nine separate patient-reported outcomes. The primary outcomes were the pain subscale of the Knee injury and Osteoarthritis Outcome Score (KOOS) and the average of all five KOOS subscales (KOOS Overall). Treatment cessation was defined as permanent device removal in the MMR group and any surgical procedure to the index knee in the non-surgical care group. RESULTS: Treated subjects had a median age of 52 years old (range 30-69 years) and one or more previous partial meniscectomies at a median of 34 months (range 5-430 months) before trial entry. Among 127 subjects treated with either MMR (n = 61) or non-surgical care (n = 66), 11 withdrew from the trial or were lost to follow-up (MMR, n = 0; non-surgical care, n = 11). The magnitude of improvement from baseline to 1 year was significantly greater in subjects who received MMR in both primary outcomes of KOOS Pain (P = 0.013) and KOOS Overall (P = 0.027). Treatment cessation was reported in 14.5% of non-surgical care subjects and only 4.9% of MMR subjects (n.s.). CONCLUSION: Treatment with the synthetic MMR implant resulted in significantly greater improvements in knee pain, function, and quality of life at 1 year of follow-up compared to treatment with non-surgical care alone.

Arthroscopic Rotator Cuff Repair With Concomitant Capsular Release.

Patients with rotator cuff tears may present with or subsequently develop concomitant shoulder stiffness. The treatment of rotator cuff tears in the face of passive glenohumeral motion loss is controversial. Preoperative shoulder stiffness has been considered by some a contraindication to rotator cuff repair. Some surgeons recommend staging surgical procedures and delaying rotator cuff repair until shoulder stiffness has resolved. However, this can lead to prolonged recovery times and patient dissatisfaction. We describe a surgical technique that allows for the single-stage arthroscopic management of rotator cuff tears with associated adhesive capsulitis. Arthroscopic capsular release and shoulder manipulation are performed in the same operative setting as arthroscopic rotator cuff repair. We have found that this combined, single-stage arthroscopic approach can effectively treat patients with rotator cuff tears and concomitant shoulder stiffness.
