Abstract
PURPOSE: Modified postural stability after retaining the posterior cruciate ligament (PCL) in total knee arthroplasty is still discussed controversially. The objective of this study was to evaluate whether a PCL-retaining implant design should be preferred over a PCL-substituting implant design regarding postural stability in one-leg stance and clinical outcome. METHODS: Forty patients underwent total knee arthroplasty, 20 of them with a cruciate-retaining (CR) and 20 of them with a cruciate-substituting (PS) implant system. Postural stability was analysed 6 months postoperatively in one-leg stance using the Biodex Balance System. In addition, the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Knee Society Score were completed. RESULTS: This study shows that there is no significant difference in postural stability between CR and PS) implant systems with PS implants showing better results in WOMAC score. CONCLUSIONS: In case it is necessary to use a PS implant, no negative influence on postural stability is to be expected compared to a CR implant.
