| Objective: To investigate the preliminary clinical outcome of total knee arthroplastyin the treatment of advanced rheumatoid arthritis.Method: In hospital from March2010to February2012, a total of24patients (30knees) with rheumatoid arthritis underwent total knee arthroplasty. All patients weretreated with posterior stabilized total knee system and without patellar replacement. All ofthem had been followed up for average12months(3-27months).Clinical results wereevaluated preoperatively and postoperatively using HSS scoring system, and the ranges ofmotion were measured．Result: The ranges of motion of their knees were average80.56±19.25degreespreoperatively,and average104.70±16.64degrees postoperatively. The mean value of thescores according to HSS was average47.6±13.1preoperatively, and average84.2±14.2postoperatively. According to HSS, the results were excellent in24cases, good in6.Wound delayed healing in2cases after operation, the remaining patients had no othercomplications.All the X-ray films of the knees implanted were analyzed. Nomal-alignment or lucent line with the prosthesis was seen in all these X-ray films．Conclusions:The preliminary clinical outcome of total knee arthroplasty in thetreatment of advanced rheumatoid arthritis is satisfactory, while long term follow-up isneeded. |
