Abstract
Aim: To determine the viability and long term survival of a unique Patellar reconstruction technique, using the posterior femoral condyle, at primary TKR, in patients with previous patellectomy.
Methods: The posterior lateral femoral condyle cut during total knee replacement was used as a non- vascularised bone graft to reconstruct the patella. A medial para- patellar incision was used to create a Patellar pouch. The patient was examined clinically at operation, 6 weeks, 12 months, 2 years and 4 years from operation. Clinical examination and radiographic evidence of patellar position and survival were used.
Results: The patient has a stable, well positioned patella, with no pain from the graft and no clinical evidence of Mal- tracking. Radiographs show excellent survival of the graft and good position at 4 years.
Conclusion: Patellar reconstruction using non- vascularised bone graft via a medial patellar pouch is a viable alternative surgical option to aid stability in those patients undergoing primary TKR with previous patellectomy.
