ABSTRACT
PURPOSE:
The purpose of this study is to analyse clinical and radiologic results of total knee arthroplasty in complete or partial ankylosed knee. MATERIALS ANDMETHODS:
From July 1986 to August 1996, total knee arthroplasties were performed in 37 ankylosed knees. Of these, five patients were lost to follow-up. Thirty two patients were evaluated. The average follow up period was 5 years 2 months (2 years-11 years 10month). Average age of patients at the time of total knee arthroplasty was 40.4 years (20~63 years). There were seven men and twenty five women. Twenty patients had complete ankylosis and twelve patients had partial ankylosis. Quadriceps tendon was lengthened with the method of modified V-Y advancement technique in 10 cases. Tibial tubercle was proximally transferred in 3 cases.RESULTS:
The postoperative average range of motion was 75.3 degrees (30 degrees - 115 degrees) in complete ankylosis, 98.7 degrees (60 degrees -130 degrees) in partial ankylosis. The average HSS knee score improved from 56.8 points preoperatively to 85.6 points postoperatively. Radiolucent line was observed in two knees with less than 2mm width in 3 years and 4 years postoperatively, but the patient had no pain.CONCLUSION:
In patient selection, healthy extensor mechanism and adequate soft tissue condition are most important. With meticulous surgical technique and aggressive rehabilitation, patients can obtain reasonable restoration of function in ankylosed knee after total knee arthroplasty.
