Abstract:

BACKGROUND: The choice of prosthesis in total knee arthroplasty is still controversial.
OBJECTIVE: To observe the early clinical efficacy of conventional fixation platform, rotation mobile platform and high-flexion prosthesis in total knee arthroplasty.  
METHODS: The clinical data were analyzed retrospectively from patients undergoing primary total knee arthroplasty for osteoarthritis between January 2006 and December 2009. The KSS score, SF-36 score and maximal range of knee flexion in three groups were recorded at preoperative moment, postoperative 3, 6, 12 months and after 1 year.  
RESULTS AND CONCLUSION: All the involved patients were followed up. Compared with preoperative data, postoperative KSS score, SF-36 score and maximal range of knee flexion were significantly improved after arthroplasty (P < 0.05). There was no significant difference in KSS score, SF-36 score and maximal range of knee flexion between three groups at the same time and among different groups at respective time (P > 0.05). These three kinds of prostheses showed good and excellent clinical efficacy for osteoarthritis, the patients were satisfied, and maximal range of knee flexion was improved. But there is no significant difference on early clinical efficacy, subjective satisfaction of patients and maximal range of knee flexion among the three kinds of prosthesis.
