Patella resurfacing in total knee replacement (TKR) has been shown to reduce the rate of anterior knee pain, but there are complications from patella resurfacing. A 54-year-old male underwent a left primary TKR with patella resurfacing 15 years ago. He developed spontaneous progressive anterior knee pain for six months. At revision surgery, his patella button was found to be loose. Loosening of a three-peg patella button is rare. A high index of suspicion of patella button loosening should be suspected in patients who present with anterior knee pain after patella resurfacing.
全膝关节置换术（TKR）中的髌骨表面置换已被证明可降低前膝痛的发生率，但髌骨表面置换存在并发症。一名54岁男性15年前接受了左膝初次TKR并进行了髌骨表面置换。他出现自发性进行性前膝痛6个月。在翻修手术中，发现他的髌骨纽扣松动。三钉髌骨纽扣松动很少见。对于髌骨表面置换后出现前膝痛的患者，应高度怀疑髌骨纽扣松动。
