Aim: Cam impingement in the hip is well recognised with the relative incongruity between the femoral head and acetabulum implicated in the development of osteoarthritis (OA). We propose that a similar situation may occur in the knee joint and explain the commonly observed anteromedial OA in medial compartment disease. This study asked whether a relatively larger femoral condyle could cause impingement on the smaller tibial articular surface and result in early osteoarthritis (OA).
Methods: A retrospective randomised study of 400 age and sex matched knee x-ray and MRI scans of patients aged between 40 and 60 years was performed. Patients with any conditions that could affect their knee joint congruence or predispose them to degenerative changes were excluded. Measurements of the femoral and tibial articular surfaces were performed in the coro.. View More»
