CASE
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.
CONCLUSION
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.
病例
指甲髌骨综合征（NPS）是一种遗传性疾病，会导致膝盖的解剖异常，包括明显的髌骨发育不良。我们报告了一例 NPS 合并严重膝骨关节炎的患者，行计算机辅助全膝关节置换术（TKA）。术中发现了几个解剖学挑战。术后，患者发生了需要手法松解的关节纤维性僵直，但最终结果良好。
结论
计算机辅助可能会提高 NPS 患者行 TKA 的精确性，但外科医生必须了解相关的解剖异常和潜在的关节纤维性僵直风险增加。由于骨量不足，髌骨表面置换通常不可行。
