Knee Osteoarthritis (Subscribe)  

Degenerative joint disease can affect any or all of the compartments of the knee joint. This article addresses arthrosis that is localized to the lateral compartment of the knee. The typical radiographic signs that are associated with degenerative joint disease consist of narrowing of the joint space, subchondral cyst formation, bone...

Optimal surgical management of the unicompartmental osteoarthritic knee has eluded the orthopedist for decades. McKeever is credited with recognizing that arthritis of the knee could be unicompartmental in nature. Treatment options for medial compartment arthritis have varied extensively, including valgus unloading braces; opening or closing wedge osteotomies of the proximal...

February 27, 2008 — The Osteoarthritis Research Society International (OARSI) has issued 25 evidence-based, expert consensus recommendations for the management of osteoarthritis (OA) of the hip and knee. These guidelines, which are published in the February issue of Osteoarthritis and Cartilage, were intended to be adapted for use in different...

Patellofemoral osteoarthritis is common clinically and often independent of tibiofemoral disease. Intriguingly, the patella demonstrates more severe degeneration earlier in the disease process compared with the juxtaposed femoral groove. Here, we consider three hypotheses influencing this disparity and thus discover crucial insights into the etiology of osteoarthritis.

Patellofemoral arthritis usually affects the same patient population affected by arthritis of other joints. Increasing age, obesity, overuse, chronic joint instability, prior interarticular fractures, and systemic inflammatory conditions are risk factors for the development of arthritis in the hip, knee, patella, and other weight-bearing joints. Patellofemoral arthritis can also occur...
