Total knee arthroplasty following failed high tibial osteotomy: mid-term comparison of posterior cruciate-retaining versus posterior stabilized prosthesis.
This study evaluated the mid-term results of total knee arthroplasty (TKA) following high tibial osteotomy (HTO), comparing posterior cruciate-retaining prostheses to posterior stabilized prostheses. The Knee Society score for the entire group (20 knees) improved significantly from 62 (median) preoperatively to 87 at the latest follow-up. The postoperative Knee Society score of 85 in posterior cruciate-retaining prostheses (8 knees) was significantly inferior to the 94 score in posterior stabilized prostheses (12 knees). Of Knee Society score, Stability and ROM scores (17 and 21, respectively) in posterior cruciate-retaining TKA were inferior to those in posterior stabilized TKA (25 and 24, respectively). Since postoperative knee instability due to posterior cruciate ligament (PCL) insufficiency is thought to contribute to the inferior results of posterior cruciate-retaining prostheses after HTO, PCL-substituting TKA would be suitable for use after HTO.
