Patellar compression syndrome may be a manifestation of contraction of the lateral retinacular structures which consists largely of the lateral patellofemoral ligament producing a tethering action on the patella. This may produce parapatellar pain, particularly in activities requiring repetitive knee flexion. Minor patellofemoral incongruencies with pain, grating, and functional limitation may be found on examination but the patient does not demonstrate the problems of instability of marked congenital abnormalities often seen with other patellar problems. Forty patients underwent a simple release of the lateral retinaculum to decompress the patella in the patellofemoral groove. Follow-up was obtained in 31 patients at an average of 18.3 months after surgery. Twenty-four knees which had severe preoperative pain were converted to 6 with no pain, 4 with mild pain, 11 with moderate pain and 3 whose pain remained unchanged after surgery. Twenty knees with moderate preoperative pain were changed to 4 with no pain, 11 with mild pain and 4 whose pain remained unchanged. Thirty-seven of the 45 knees had lessening of the pain after the operation and 10 patients returned to unrestricted atheletic activities.
髌股压迫综合征可能是外侧支持带结构收缩的一种表现，外侧支持带结构主要由髌股外侧韧带组成，对髌骨产生牵拉作用。这可能会导致髌旁疼痛，尤其是在需要反复屈膝的活动中。检查时可能会发现轻微的髌股关节不匹配，伴有疼痛、摩擦音和功能受限，但患者没有表现出其他髌股问题中常见的明显先天性异常的不稳定问题。40例患者接受了外侧支持带的简单松解，以减轻髌股关节沟内髌骨的压力。31例患者术后平均18.3个月进行了随访。术前有严重疼痛的24个膝关节，术后转变为6个无痛、4个轻度疼痛、11个中度疼痛和3个疼痛无变化。术前有中度疼痛的20个膝关节，术后转变为4个无痛、11个轻度疼痛和4个疼痛无变化。45个膝关节中有37个术后疼痛减轻，10例患者恢复了不受限制的体育活动。
