Excision of the fat pad is common in total knee arthroplasty to enhance surgical exposure. However, the effect of this has not been clearly established. A retrospective review of 1055 primary total knee arthroplasties was preformed in 720 patients from 1997 to 1998. Regression analysis was performed to determine the effect of excising the fat pad on patellar tendon contracture, range of motion, Knee Society Score, function, and pain scores. Fat pad excision had no significant effect on patellar tendon contracture (P = .4599), range of motion (P = .7361), Knee Society Score (P = .7247), or function scores (P = .6786). Patients whose fat pad had been removed were nearly twice as likely to experience postoperative pain (P = .0005).
在全膝关节置换术中，切除脂肪垫以增加手术视野很常见。然而，其效果尚未明确。对1997年至1998年720例患者的1055例初次全膝关节置换术进行了回顾性研究。进行回归分析以确定切除脂肪垫对髌腱挛缩、活动范围、膝关节协会评分、功能和疼痛评分的影响。脂肪垫切除对髌腱挛缩（P = 0.4599）、活动范围（P = 0.7361）、膝关节协会评分（P = 0.7247）或功能评分（P = 0.6786）无显著影响。脂肪垫被切除的患者术后疼痛的可能性几乎是未切除患者的两倍（P = 0.0005）。
