The primary aim of the study was to evaluate the range of motion and complications after Genesis II total knee arthroplasty with high flexion tibia insert (TKA-HF). Furthermore, difference in knee flexion between high flexion and standard inserts was compared. The hypothesis was that knee flexion is better after high flexion TKA.
A total of 292 TKA-HF were retrospectively reviewed. Mean follow-up was 24.3 months. The range of motion was compared between TKA-HF (high flexion group) and a comparable cohort of 86 Genesis II TKA with a standard tibia insert (control group). Surgeries were performed by one experienced knee orthopaedic surgeon.
Knee flexion in the high flexion group increased from 114.8° pre-operatively to 118.0° postoperatively (P<0.01). Knee extension in the high flexion group increased from -4.5° preoperatively to 0.4°after surgery (P<0.01). Mean knee flexion was 5.52°(+/- 1.46°) better in the high flexion group compared to the control group (P<0.01). Preoperative range of motion, body mass index (BMI), diabetes mellitus and patellofemoral pain significantly influenced range of motion. Few complications occurred after TKA-HF.
The Genesis II TKA-HF showed good short term results with limited complications. Knee flexion after Genesis II TKA-HF was better compared to a standard tibia insert.
