Abstract:
Objective To evaluate the clinical results of the PCL-retaining total arthroplasty in treatment of knee osteoarthris with valgus.Methods From June 2002 to January 2005,8 cases of osteoarthris with valgus knee were treated with PCL-retaining total knee replacement.The X-ray before operation showed average 21.6 degrees(ranging from 10 to 35 degrees) valgus.The cases were follow-uped from 6 to 36 months,each of them was evaluated with the Special Surgery Knee Scoring System.Results The X-ray after operation showed average 5.7 degrees(ranging from 3 to 9 degrees) valgus.The average HSS scores increased from preoperative 54 to postoperative 91.The range of motion was significantly improved from preoperative 83 degrees to postoperative 118 degrees.All of the cases were no pains after operation,and the function of knees were apparently improved.Conclusions The preliminary clinical results are quite satisfactory for the PCL-retaining total arthroplasty in treatment of osteoarthris with valgus knee.The adequate relaxing and balancing of soft tissue is the key factor to the success of total knee arthroplasty.The follow-up is necessary for further long-term outcome.
