Abstract: Objective To evaluate the clinical efficacy of total knee arthroplasty(TKA)in patients of osteo-arthris with valgus knee deformity after lateral meniscectomy(LMT). Methods Twenty six cases of osteo-arthris with valgus knee deformity after lateral meniscectomy were treated with total knee arthroplasty. Operation evaluations including the range of motion(ROM),the tibial and femur angle(T-F angle),Knee Society Score System(KSS)and the function score were performed as follow-up. Results The median follow-up periods was 22 months and ranged from 5 months to 3 years. The average ROM improved from 96° preoperatively to 116° at postoperatively. The average KSS improved from 22. 5 points preoperatively to 84. 4 points postoperatively. The average function score improved from 25. 5 points preoperatively to 84. 4 points postoperatively,and the average T-F angle was corrected from 22°( 13° - 31°) of valgus preoperatively to 7. 6°( 0° - 9°) of valgus postoperatively. Conclusion The TKA can provide excellent in patients undergoing osteo-arthris with valgus knee deformity after lateral meniscectomy.
