Second-look Arthroscopic Evaluation of Cartilage Regeneration After Medial Opening-wedge High Tibial Osteotomy
In Brief
A clinical study evaluating initial arthroscopy with medial opening-wedge high tibial osteotomy fixed by a plate system then second look arthroscopy with plate removal for Osteo Arthritis Knee. Completed, enrolled 49 participants across 2 sites.
Detailed Summary
Osteoarthritis of the knee is a common problem causing significant knee pain and disability. Medial compartment osteoarthritis is predisposed to by varus deformity of the knee. High tibial osteotomy is a well-established method for treatment of medial unicompartmental knee osteoarthritis and correction of varus deformity.
Study Details
Timeline
Interventions
It is a joint preserving procedure especially preferred in young patients for whom arthroplasty is not desirable. The procedure promotes regeneration by causing lateral shift of the weight-bearing axis, thus decreasing load on the medial compartment and widening the medial joint space.Many of the patients complains of irritation through the plate and wish metal removal after healing of the osteotomy.All patients will undergo initial arthroscopy before high tibial osteotomy (HTO). During arthroscopy, debridement of the degenerate tissues and meniscal tears if present will be performed. Then opening-wedge high tibial osteotomy (OWHTO) will be performed and fixed by a plate system. Second-look arthroscopy will be conducted at the time of plate removal after healing of the osteotomy. This will be after about 6 months up to one year.
