OBJECTIVE To investigate the risk factors for meniscal damage, an important determinant of knee osteoarthritis. METHODS We studied 243 men and women aged 20-59 years in whom the diagnosis of a meniscal tear was confirmed for the first time at arthroscopy, over a 25 month period, in 2 British hospitals. Each case was compared with one or 2 community controls, matched by age and sex, who were r...

Background and purpose - Recent evidence has questioned the effect of arthroscopic knee surgery for middle-aged and older patients with degenerative meniscal tears with or without concomitant radiographic knee osteoarthritis (OA). We investigated the prevalence of early or more established knee OA and patients' characteristics in a cohort of patients undergoing arthroscopic surgery for a menisc...

Meniscectomy is recognized as an important risk factor for the development of knee osteoarthritis (OA), a disease that traditionally has been considered as a simple "wear and tear" phenomenon. However, despite numerous reports, little evidence has been presented that a limited meniscal resection, compared with a more extensive resection, reduces the risk of OA by preserving meniscal function. W...

BACKGROUND In patients with degenerative meniscal tears, subclinical cartilage degeneration may be present even if gross morphological changes are not evident. The aim of this study was to detect occult cartilage degeneration using T1ρ MRI mapping in patients with meniscal tears without obvious radiographic osteoarthritis (OA). METHODS A total of 22 subjects with degenerative meniscal tears i...

Background and purpose - No consensus exists on when to perform arthroscopic partial meniscectomy in patients with a degenerative meniscal tear. Since MRI and clinical tests are not accurate in detecting a symptomatic meniscal lesion, the patient's symptoms often play a large role when deciding when to perform surgery. We determined the prevalence and severity of self-reported knee symptoms in ...

OBJECTIVES  To compare patient reported outcomes from before surgery to 52 weeks after surgery between individuals undergoing arthroscopic partial meniscectomy for traumatic meniscal tears and those for degenerative meniscal tears. DESIGN  Comparative prospective cohort study. SETTING  Four public orthopaedic departments in the Region of Southern Denmark. Participants were recruited between...

INTRODUCTION Meniscal tear is thought to play a crucial role in onset as well as progression of arthritis. However, role of cytokine response to meniscal injury and resulting inflammation is not clearly understood. Because synovial fluid is juxtaposed to cartilage and serves as a biological connection between chondrocytes and synoviocytes, we chose synovial fluid analysis to ascertain biochemic...

To the Editor: Previous studies have suggested that partial meniscectomy has little benefit in patients with advanced osteoarthritis1,2 but some benefit in those with mild-to-moderate osteoarthritis.3 Sihvonen and colleagues (Dec. 26 issue)4 attempted to assess the benefit of partial meniscectomy in patients without osteoarthritis. However, although the authors excluded patients with radiograph...

Meniscal lesions often occur in association with anterior cruciate ligament (ACL) tears at the moment of injury or, secondarily, as a consequence knee instability. Both ACL and meniscus are associated higher risk osteoarthritis. Adequate treatment these reduces rate degenerative changes affected knee. should be addressed concomitantly reconstruction must oriented towards preserving meniscal tis...
