Lateral Compartment Arthritis eMedicine Orthopedics

Bal & Upadhyay — 2008-04-04 09:09:29 GMT

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 sclerosis, and hypertrophic osteophytic spurring (Altman et al, 1987; Gresham and Rathey, 1975). Lateral compartment arthrosis is encountered less frequently than a genu varum deformity because the medial joint compartment of the knee is most commonly affected by degenerative changes, followed by the patellofemoral and lateral compartments (Johnson and Bodell, 1981).

Medial Compartment Arthritis eMedicine Orthopedics

Scott E Marwin, MD & Kevin Trapp, MD — 2008-04-04 09:09:29 GMT

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 tibia, distal femur, or both; and unicompartmental or total knee arthroplasty (TKA). Problem: The problem facing the orthopedist in unicompartmental arthritis is addressing single compartment articular cartilage wear and biomechanical overload while preserving the integrity of the remaining knee joint. Conservative measures including bracing, weight loss, physical therapy, and injection may provide temporary relief, often delaying the need for surgical intervention. Surgical options include arthroscopy, joint debridement, microfracture, osteotomy alone, or cartilage replacement in conjunction with osteotomy. Depending upon the severity of articular cartilage damage and joint deformity, one or more of these measures may ameliorate symptoms such that no further intervention is required. In cases of recurrent pain, a unicompartmental or conventional total joint arthroplasty may be undertaken.

New Guidelines Issued for Management of Hip and Knee Osteoarthritis Medscape CME

Not Available — 2008-04-07 09:09:29 GMT

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 countries or regions according to the availability of treatment modalities and strength of recommendation (SOR) for each modality of therapy.

Osteoarthritis What We Have Been Missing in the Patellofemoral Joint Medscape

Clark — 2008-04-07 09:09:29 GMT

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 eMedicine Orthopedics

Hogan & Schutte — 2008-04-06 09:09:29 GMT

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 in younger patients as a result of malalignment or trauma.

Surgical difficulties for total knee replacement in Stickler syndrome - a case report

Verma et al — 2008-09-27 09:09:29 GMT

Stickler syndrome is believed to be the most common connective tissue disorder in Europe and the USA. Severe osteoarthritis sets in at very early age in 3rd to 4th decade of life necessitating joint arthroplasty. This case report highlights the intraoperative surgical difficulties faced by the surgeon and the planning needed for the operation.
