Abstract:
Objective To investigate the feasibility and clinical effect of one-stage total knee arthroplasty for old femoral condyle fractures combined with knee osteoarthritis.Methods From January 2003 to December 2010,11 patients with old femoral condyle fracture combined with knee osteoarthritis,including 4males and 7 females,aged from 38 to 77 years (average,58.3 years),underwent one-stage total knee arthroplasty.There were 8 cases of supracondylar fracture,and 3 cases of intercondylar fracture.Moreover,there were 2 cases of knee fibrous ankylosis with mild amyotrophy,3 cases of collateral ligaments injury of the knee,2 cases of fibrous union,and 2 cases of infective nonunion.Results All patients were followed up for 6 to 72 months (average,41.3 months).The HSS score improved from preoperative 6.65±7.01 (range,0-13)to 88.5±6.18 (range,81-95) at final follow-up.The range of motion of the knee improved from preoperative 32.7°±17.6° (range,0°-50°) to 101.3°±9.8° (range,85°- 115°) at final follow-up.One case underwent knee disarticulation 6 years after operation owing to infection.For other patients,there were no complications such as infection,deep vein thrombosis,knee instability,component loosening and inequality of lower limb.Conclusion One-stage total knee arthroplasty is a technically difficult but effective method for patients with old femoral condyle fracture and knee osteoarthritis.
