摘　　要：BACKGROUND Total patellectomy is currently reserved for exceptional cases,such as recalcitrant patellofemoral instability and comminuted fractures,due to its demonstrated negative impact on knee biomechanics.Therefore,managing patellectomy is crucial to mitigate its inherent deleterious effects.Various techniques have been described,including autologous or allogeneic bone grafts for reconstruction and soft tissue realignment to enhance the extensor mechanism.CASE SUMMARY A 73-year-old male underwent a patellectomy due to a comminuted fracture,subsequently developing osteoarthritis and experiencing a decline in functional status.Concurrent with total knee replacement,we conducted a patellar reconstruction,incorporating routine bone cuts and utilizing bone chips to fashion a new patella.This intervention resulted in the restoration of full extension and improvement of knee function.CONCLUSION Patellar reconstruction demonstrates benefits on knee mechanics and stabilization,contributing to enhanced outcomes and satisfaction following knee replacement.We present an affordable technique for managing patellectomized patients undergoing total knee replacement.
