Abstract: ObjectiveTo investigate the feasibility, technical strategies, and clinical advantages of primary total knee arthroplasty (TKA) in treating elderly patients with Schatzker type II/III tibial plateau fractures complicated by osteoarthritis, offering a novel approach to address the high complication and reoperation rates associated with traditional open reduction internal fixation (ORIF).Methods A prospective analysis was conducted on 15 elderly patients with Schatzker II/III fractures and concomitant osteoarthritis treated at the Department of Joint Surgery, Honghui Hospital in Xi'an (October 2021-March 2023).All patients underwent strict preoperative evaluation (imaging analysis of fracture extent, bone defect type, and osteoporosis severity) followed by single-stage TKA.The standardized surgical protocol included: 1. Anteromedial parapatellar approach with osteotomy level adjusted based on tibial tubercle integrity.2. Three-step tibial baseplate reconstruction combined with cement fixation and stem extension for stability.3. Constraint-level prosthesis selection guided by ligament status, with concurrent bone defect management (autograft/tumor prosthesis augmentation).4. Accelerated rehabilitation: Partial weight-bearing within 1-3 days and full weight-bearing at 4 weeks postoperatively.Postoperative outcomes (VAS, HSS scores, ambulation time, thrombosis rates, prosthesis loosening, and patient satisfaction) were systematically evaluated. ResultsAll 15 patients completed a 1-year follow-up.Compared to historical ORIF data, the primary TKA group demonstrated accelerated functional recovery, achieving 100% partial weight-bearing by the postoperative 3rd day.92% achieved full weight-bearing at 4 weeks.70% reduction in immobilization-related complications (DVT, pneumonia).Significant pain relief: VAS decreased from 7.5 ± 1.2 preoperatively to 1.8 ± 0.6 at 3 months.HSS improved from 45 ± 10.2 to 88 ± 6.4.Avoidance of secondary surgeries: 95% patient satisfaction with single-stage fracture-arthritis resolution.Long-term stability (postoperative 1 year): 0% prosthesis loosening rate.No infections or mechanical failures. ConclusionsPrimary TKA provides a definitive single-stage solution for elderly patients with Schatzker II/III fractures and preexisting osteoarthritis, achieving simultaneous fracture reduction, joint reconstruction, and rapid rehabilitation.This approach significantly reduces complications, shortens hospitalization, and enhances quality of life.Future studies should validate long-term outcomes in larger cohorts and refine prosthetic designs for complex bone defects.
