Abstract:
Objective To investigate the effect of total knee arthroplasty ( TKA) following high tibial osteotomy ( HTO) and to analyze the factors that may influence the operation .Methods A total of 16 patients (19 knees) who had undergone a previous HTO were treated with TKA between 2000 and 2010.The American Knee Society Scores ( KSS), femorotibial angle ,quadriceps angle ,posterior slope angle of tibial plateau ,Insall Salvatti Ratio and knee range of motion ( ROM) were evaluated for each patient pre-and post-operatively and the results were evaluated .Results The KSS scores improved from 73.20 ±3.56 scores preoperatively to 153.00 ±3.39 scores postoperatively (P <0.05).The femorotibial angle was corrected from 160.57°±3.30°preoperatively to 169.85°±1.34°postoperatively(P<0.05).The quadriceps angle was corrected from 24.57°±2.07°preoperatively to 17.28°±1.11°postoperatively (P<0.05).The posterior slope angle of tibial plateau was corrected from 2.25°±0.50°preoperatively to 3.75°±0.95°postoperatively (P<0.05).The Insall Salvatti Ratio improved from 0.80 ±0.08 preoperatively to 1.05 ±0.12 postoperatively ( P <0.05).The knee ROM improved to 38.25°±8.88°postoperatively from 96.25°±4.34°preoperatively(P<0.05).Conclusion TKA following HTO demands adequate soft tissue balancing , good limb alignment and appropriate prosthesis .
