Objective:To systematically investigate the short-term efficacy of total knee arthroplasty in the treatment of osteoarthritis coupled with fixed patellar dislocation.Methods:A retrospective analysis was conducted on a cohort of 11 patients diagnosed with knee osteoarthritis and fixed patellar dislocation who underwent total knee arthroplasty at Panzhihua Central Hospital from January 2018 to October 2021. The cohort comprised 4 males and 7 females, aged 63.45±4.76 years (range, 56-70 years), all of whom underwent unilateral surgery. There were 5 left and 6 right knees, with a body mass index of 23.20±2.02 kg/m 2 (range, 20.8-27.6 kg/m 2) and a disease course of 12.63±4.81 years. According to the American Society of Anesthesiologists classification, 9 cases were categorized as grade II, and 2 cases as grade III. Recovery of patellar trajectory during total knee arthroplasty, using medial synovial flap transposition to repair lateral joint capsule. Preoperative and postoperative assessments included knee joint range of motion, Knee Society score (KSS), University of California Los Angeles (UCLA) score, and visual analogue scale (VAS). Results:All 11 patients were followed up for a period of 28.64±4.01 months (range, 24-36 months). Two patients exhibited subcutaneous fat liquefaction locally after surgery, which resolved following dressing changes. All wounds achieved primary healing. Two of them developed intramuscular vein thrombosis after surgery and were cured after anticoagulant treatment. The range of motion of the knee joint increased from 63.18°±17.07° before surgery to 104.55°±16.80° at the last follow-up, with a statistically significant difference ( t=14.041, P<0.001). The KSS score increased from 38.00±6.78 points to 80.91±5.65 points, with a statistically significant difference ( t=16.472, P<0.001). The UCLA score increased from 3.18±1.17 to 6.73±1.35, with a statistically significant difference ( t=9.694, P<0.001). The VAS decreased from 6.09±0.94 points to 2.32±0.64 points, with a statistically significant difference ( t=16.600, P<0.001). At the last follow-up, imaging examinations showed no cases of patellar subluxation or dislocation, no tearing or breakage of the knee extension device, and no infection or loosening around the prosthesis. Conclusion:Utilizing medial synovial flap transposition for repairing the lateral joint capsule proves to be an effective technique for key capsule repair. Total knee arthroplasty for osteoarthritis combined with fixed patellar dislocation demonstrates satisfactory early clinical outcomes.
