CEMENTLESS TOTAL KNEE ARTHROPLASTY FIVE TO SEVEN YEAR FOLLOW UP



Abstract

Between 1990–92, 59 Primary TKA’s were performed in 55 Patients with a mean follow-up of 9 years (8–10). Mean age at review was 75 years (61–87). Materials and Method: All cementless TKA’s (Whiteside Ortholoc Modular 3). One surgeon (operating or supervising). Intramedullary guides(tibia and femur). Lateral retinacular release. Clinical evaluation according to the Knee Society Scoring System & Knee Society TKA Roentgenographic Evaluation and Scoring System. Median Knee Score 93.5 (41–97). Median Functional Score 77.5 (35–100). Median flexion 100 degrees (80–120). All but one knee came to full extension. No effusions or swellings. Radiolucencies in one TKA only. Discussion: Long term success of TKA’s (cementless or cemented) depends on correct alignment of the implants. Rigidity of fixation is the second most important feature in achieving pain free function in an arthroplasty. Success in this series was due to good alignment of components. Good alignment minimises polyethelene wear. Rigid tibial fixation prevents motion, tilting and malalignment reducing wear.
