The authors report on synovial folds of the knee examined by arthroscopy. 60 arthroscopies in 59 patients showed a plica synoviale. The authors recount the different anatomical types. A suprapatellar plica is found in all the cases and a lateropatellar plica is found in 7 out of 60 cases. The suprapatellar plica forms a fibrous fold which is sometimes completely folded off (6.6%) but more often it is an incomplete fold: internal (66.6%), external (21.6%) or annular (15%). In some cases arthroscopy reveals cartilaginous lesions associated with the plica. 18 patients out of 37 showed lesions of secondary chondromalacia. Endoscopic resection offers a possibility of treatment for this condition. The results of this operation were good or excellent in 64.7% of the patients without cartilaginous complications and in 40% of the patients who had a lesion of their cartilages. In the discussion the authors present the possible physiopathology of this syndrome and the presenting symptoms.
作者报告了通过关节镜检查的膝关节滑膜皱襞情况。59例患者的60次关节镜检查显示有滑膜皱襞。作者详述了不同的解剖类型。所有病例均发现有髌上皱襞，60例中有7例发现有髌外侧皱襞。髌上皱襞形成一个纤维性皱襞，有时会完全折叠（6.6%），但更常见的是不完全折叠：内侧（66.6%）、外侧（21.6%）或环形（15%）。在某些情况下，关节镜检查显示与皱襞相关的软骨损伤。37例患者中有18例出现继发性软骨软化症病变。内镜下切除为这种疾病提供了一种治疗可能性。在无软骨并发症的患者中，该手术结果为良好或优秀的比例为64.7%，在有软骨损伤的患者中这一比例为40%。在讨论中，作者介绍了该综合征可能的病理生理学及出现的症状。
