We evaluated the association between patellofemoral relationships and cartilage lesions in patients (age range 15-49) with anterior knee pain without patellar dislocation (n = 24) and in patients with isolated meniscal rupture without a high energy trauma (n = 21). The position of the patella was assessed from knee radiographs, and cartilage lesion was graded and mapped at arthroscopy. In subjects with lateral patellar cartilage lesion the patella tilted laterally (p < 0.01) and was clearly laterally displaced (p < 0.001), compared to those without patellar cartilage lesion. In subjects with central patellar cartilage lesion the patella located high according to the Insall-Salvati index (p < 0.01) and was somewhat laterally displaced (p < 0.05). Compared to subjects without cartilage lesion in the femoral trochlea, the patella was laterally displaced in subjects with lesion in the lateral trochlea (p < 0.001). In conclusion, our results suggest that specific malalignments predispose to patellofemoral cartilage lesion, but prospective studies are needed to confirm the finding.
我们评估了无髌骨脱位的前膝痛患者（年龄范围15 - 49岁，n = 24）以及无高能创伤的单纯半月板破裂患者（n = 21）的髌股关系与软骨损伤之间的关联。通过膝关节X线片评估髌骨位置，并在关节镜检查时对软骨损伤进行分级和定位。与无髌骨软骨损伤的受试者相比，有外侧髌骨软骨损伤的受试者髌骨向外侧倾斜（p < 0.01）且明显向外移位（p < 0.001）。根据Insall - Salvati指数，有中央髌骨软骨损伤的受试者髌骨位置较高（p < 0.01）且稍有向外移位（p < 0.05）。与股骨滑车无软骨损伤的受试者相比，外侧滑车有损伤的受试者髌骨向外移位（p < 0.001）。总之，我们的结果表明特定的排列不齐易导致髌股软骨损伤，但需要前瞻性研究来证实这一发现。
