The pie-crusting method of ligament and tendon lengthening has been used successfully in various tissues but is not reported in the literature as an option for patellar or quadriceps tendons to address flexion limitation. Our case report discusses a patient with longstanding flexion limitation who underwent primary total knee arthroplasty. The report reviews the literature on intraoperative treatments, which primarily pertains to the condition of patella baja, and demonstrates that the pie-crusting technique should be included as a treatment option for a tight extensor mechanism while having some advantages over tibial tubercle osteotomy or Z-plasty.
韧带和肌腱延长的“馅饼皮”技术已成功应用于各种组织，但文献中未报道其可作为治疗髌骨或股四头肌肌腱屈曲受限的一种选择。我们的病例报告讨论了一名患有长期屈曲受限的患者，该患者接受了初次全膝关节置换术。该报告回顾了关于术中治疗的文献，这些文献主要涉及低位髌骨的情况，并表明“馅饼皮”技术应作为一种治疗伸肌机制紧张的选择，且相对于胫骨结节截骨术或Z形成形术具有一些优势。
