During total knee arthroplasty, the reconstruction of the patella following a previous patellectomy is challenging, and is undertaken to improve functional outcomes and patient satisfaction. In this case series, we have reconstructed the patella using a femoral condyle resected during total knee arthroplasty. The resected femoral condyle with best available bone stock is selected and secured to the extensor mechanism. We reviewed the preoperative indications and postoperative outcomes of two patients who underwent the above procedure at our Institute, and compared this to the literature. The cases include a 68-year old male (6 months follow-up) who sustained a multi-fragmentary fracture of his right patella and underwent a patellectomy 30 years previously, and a 45-year old female (4 years follow-up) who underwent a left-sided patellectomy 15 years previously following polytrauma. As a result of progressive osteoarthritis they required total knee arthroplasty, and simultaneous patella reconstruction with a femoral condyle autograft. Compared to their preoperative range of motion, both patients demonstrated an improvement post-operatively with successful pain-free knee function, with no radiological signs of graft resorption. In this limited, small series we have reported two patients who are clinically and functionally satisfied by the outcome of surgery, with comparable outcomes to alternative methods. We believe the use of a femoral condyle autograft for patellar reconstruction is a safe and simple technique that optimises knee kinematics, without associated donor morbidity.
