Abstract

PURPOSE: We report the minimum 5-year follow-up results of total knee arthroplasty with anteroposterior glide LCS(R) CompleteTM.
MATERIALS AND METHODS
From June 1999 to June 2000, we performed sixty-two primary total knee replacements with the anteroposterior glide LCS(R) CompleteTM. Fifty-eight cases were followed-up for a minimum of 5 years. The posterior cruciate ligaments were preserved in all the cases.
RESULTS
The mean Hospital for Special Surgery Knee Score increased from 62.9 points preoperatively to 88.6 points at the most recent follow-up. The mean knee score of the American Knee Society increased from 56.9 points preoperatively to 90.8 points and the functional score increased from 39.8 points to 76.8 points at the most recent follow-up. The mean flexion contracture decreased from 11.5 degrees preoperatively to 1.6 degrees and the range of motion with flexion increased from 103.5 degrees to 112.2 degrees. There was no loosening, osteolysis, or measurable polyethylene wear in any of the cases. We experienced dislocation of the polyethylene liner and guide arm in one case, but there was no revision surgery performed due to loosening or infection.
CONCLUSION
Anteroposterior glide LCS(R) CompleteTM demonstrated excellent clinical and radiological results in polyethylene wear and osteolysis; but there was no increased benefit in ranges of motion compared with fixed-bearing implants. Further follow-up is needed to obtain long-term clinical and radiological results.
