Abstract

Introduction: By 2002 the incidence of degenerative osteoarthritis of the knee in world’s population was 50 to 68%, and 20% represents unicompartmental osteoarthritis. Unicompartmental arthroplasty and tibial osteotomy are currently the treatment options for unicompartmental osteoarthritis of the knee. Even though, total knee arthroplasty is being considered the gold standard treatment for unicompartimental arthritis, the development of better designs, techniques and instruments on unicompartimental prosthesis has made them an acceptable choosable treatment.

Methods: We present a prospective analysis of the evolution and clinical outcome of patients with unicompartmental degenerative osteoarthritis of the knee, over a four years period of time (2007-2011). All patients were treated with unicompartmental arthroplasty, using a mobile tibial bearing kind of prosthesis (Oxford 3). For clinical outcome evaluation we used the Lysholm knee scale, and for radiographic assessment the Kellgren-Lawrence scale.

Results: We included 18 knees in 13 patients, 11 female and 2 male, 11 left, 7 rights, 5 bilateral. We had find out a 100 % short time survival rate for this kind of unicompatimental prosthesis, a significant improvement of pain, mobility and functional capability scores.

Discussion: Unicompartmental arthroplasty could be a valuable option for treatment in unicompartmental osteoarthritis of the knee. Further long term follow up studies will have to be performed in order to determine full survival rates and late complications for this procedure.
