Medium-term Results Evaluation between Gender-Specific x Conventional Total Knee Arthroplasty Prostheses^[*]

Abstract

Objective To compare the postoperative functional result of total knee arthroplasty (TKA) with gender-specific prosthesis versus TKA with conventional prosthesis in a 5-year period.

Methods Retrospective study with functional evaluation of 30 patients (15 patients from each group) using scores (Knee Injury and Osteoarthritis Outcome Score [KOOS], Western Ontario and McMaster Universities arthritis index [WOMAC], and The Knee Society Clinical Rating System [KSS]) and range of motion (ROM) as methods of assessment.

Results The differences found between the score values and ROM were not statistically significant.

Conclusion The gender-specific prosthesis presents functional results equal to those of conventional prosthesis after 5 years postoperatively.
