N Engl J Med 368: 1675–1684. [Prepared by Kåre B Hagen and Margreth Grotle, CAP Editors.] Question: Does arthroscopic partial meniscectomy and postoperative physiotherapy result in better functional outcomes than standardised physiotherapy (PT) alone for

symptomatic patients with a meniscal tear and knee osteoarthritis buy Gefitinib (OA)? Design: A randomised, controlled trial in a 1:1 ratio with concealed allocation. Setting: Seven US tertiary referral centres. Participants: Men and women, aged 45+ years with a meniscal tear, mild to moderate OA, symptoms for at least four weeks, managed with medications, activity limitations, or PT. Exclusion criteria comprised having a chronically locked knee, severe OA (Kellgren-Lawrence Grade 4), inflammatory arthritis, or prior surgery to the affected knee. Randomisation of 351 participants allocated 171 to arthroscopic Selleckchem Neratinib partial menisectomy followed by PT and 177 to PT alone. Interventions: Both groups received a similar PT program. The PT program was based on land-based, individualised physiotherapy with progressive home exercises. A phased structured

program was designed to decrease inflammation, restore active joint range and neuromuscular re-education of quadriceps (Phase 1), restore muscle strength and endurance, re-establish full and pain-free active joint range, gradual return to functional activities, and minimise gait deviations (Phase 2), and enhance muscle strength and endurance, and return to sports/functional activities (Phase 3). It was recommended that the patient attend PT sessions once or twice weekly for six weeks and perform exercises at home. In addition, the surgery group had arthroscopic partial meniscectomy performed by trimming the damaged meniscus back to a stable rim followed by postoperative PT. Outcome measures: The primary outcome was change in the physicalfunction scale of the Western Ontario and McMaster Universities (WOMAC)

questionnaire from baseline to six months follow up. Secondary outcomes included the pain score on the Knee Injury and Osteoarthritis Outcome Scale (KOOS) and the physical-functioning out scale of the 36-Item Short-Form Health Survey (SF-36). Results: In total, 330 patients completed the six month follow-up. There was no difference between the groups in change in the WOMAC physical-function score (mean difference 2.4 points, 95% CI −1.8 to 6.5). There were also no significant differences between the groups in the KOOS pain score, SF-36 physical functioning, or frequencies of adverse events. At six months, 51 (30%) active participants in the study who were assigned to PT alone had undergone surgery, and 9 patients assigned to surgery (6%) had not undergone surgery.
