A microminiature pressure transducer was constructed to measure chondromalacia of the medial patellar facet under arthroscopic control. Normal and abnormal values were established. Among a group of 58 knees with no patellofemoral symptoms or signs, 30 knees measured "soft" using this instrument. Among a group of 107 knees with patellofemoral symptoms and signs, 98 knees measured "soft." Of these 98 knees, 55 had no observable change in the articular surface of the patella.
构建了一种超小型压力传感器，用于在关节镜控制下测量髌内侧关节面的软骨软化症。确定了正常值和异常值。在一组58例无髌股症状或体征的膝关节中，使用该仪器测量有30个膝关节“软”。在一组107例有髌股症状和体征的膝关节中，98个膝关节测量为“软”。在这98个膝关节中，55个髌骨关节面无明显变化。
