Abstract
Background: Degenerative arthritis of the knee is prevalent, often presenting at end-stage, necessitating total knee replacement (TKR). Such cases frequently involve significant bony defects and ligamentous laxity.
Case Presentation: We report the case of a 60-year-old bedridden patient with severe bilateral end-stage knee osteoarthritis, presenting with gross bony defects. TKR was performed in two stages using a semi-constrained prosthesis. Autogenous bone graft, reinforced with cement, was utilized to reconstruct large tibial and femoral defects.
Outcome: The post-operative period was uneventful. Radiographs confirmed restoration of the tibiofemoral angle and good prosthesis positioning. This approach offered a cost-effective alternative to constrained prostheses or artificial augmentation for severe deformities.
Conclusion: Total knee replacement with autogenous augmentation presents a viable and cost-effective strategy for managing end-stage arthritis with extensive bone loss and ligamentous laxity, achieving successful clinical and radiological outcomes.
