%X Nail-patella syndrome (NPS) is a genetic disorder causing anatomical abnormalities about the knee, including significant patellar hypoplasia. We present a case of a patient with NPS and severe knee osteoarthritis undergoing computer-assisted total knee arthroplasty (TKA). Several intraoperative anatomical challenges were appreciated. Postoperatively, the patient developed arthrofibrosis requiring manipulation; however, his final outcome was favorable.<BR>Computer assistance may improve precision in patients with NPS undergoing TKA, but surgeons must be aware of the associated anatomic abnormalities and potentially increased risk of arthrofibrosis. Patellar resurfacing is often not feasible because of lack of bone stock.
