High-flexion posterior-substituting versus cruciate-retaining prosthesis in total knee arthroplasty: functional outcome, range of motion and complication comparison

摘要: Currently, a high-flexion cruciate-retaining knee prosthesis has been designed to allow greater advantage after total arthroplasty (TKA). The present study was conducted compare functional outcome, range of motion (ROM) as well complications in subjects who underwent either (HFCR, Group I) or posterior-substituting (HFPS, II) TKA. Thirty-four which had TKA with HFCR and thirty-three HFPS were enrolled our assessed preoperatively at 24 months postoperatively. For outcome comparison, Hospital for Special Surgery Score (HSSS), Knee Society (KSS, including the Mean Function Score) SF12 (including Mental Health Physical measured. ROM arcs maximal non-weight-bearing passive flexion weight-bearing detected, number knees allowed patients kneel sit cross-legged comfort determined. complication wound necrosis/discharge, anterior pain, dislocation, radiolucent lines osteolysis investigated. At 24-month follow-up, no significant difference between two groups detected. average 136.2° I 135.1° II (P > 0.05). 123.2° 129.8° No difference, regard that kneeling sitting cross-legged, Comparisons postoperative did not yield difference. Our demonstrated cruciate- retaining over short-term follow-up. However, longer follow-up is necessary confirm whether these results are sustained.
