Abstract

Aim: Total knee arthroplasty (TKA) in valgus knee is more difficult than in well aligned or varus knee, The correction of deformities and ligament balancing are the priority. The aim of this study was to evaluate our experience on 20 knees treated with Advance TKA. Methods: The study group is based on 20 consecutive patients who underwent primary TKA using cemented prosthesis fixation and a medial pivot implant. Study participants included 14 women and 6 men with a mean age of 69.6 years (range, 60 to 82 years). Osteoarthritis (80%) was the most common diagnosis rheumatoid arthritis (16%), and other findings (4%). All patients received the Advance TKA (cruciate ligament sacrificing) prosthesis (Wright) using cemented fixation. Results: Twelve knees were rated excellent, 8 as good. The femorotibial mechanical axis was corrected from a valgus of 15° to 5° in postoperative. There was no varus-valgus instability in 18 knees, and 2 knees had approximately 5° varus-valgus instability in extension. There was palpable, non-painful, patellofemoral crepitus noted in one knee. Conclusion: The Advance TKA (with cruciate ligament sacrificing) prosthesis (Wright) with cemented fixation was successful in primary arthroplasty in valgus knees, also in severe deformities with incompetent medial collateral ligament.
