Medial femorotibial osteoarthritis (MFTO) is characterised by progressive deterioration resulting, in 6 out of 10 cases, in an inability to walk after 10 to 15 years. At the surgical stage, AP films show subchondral bone wear on the edge of the medial tibial plateau with lateral tibial dislocation and lateral films show obliqueness of the medial tibial plateau possibly exceeding 10 degrees and accompanied by anterior subluxation of the tibial or even rupture of the anterior cruciate ligament. Lateral femorotibial osteoarthritis (LFTO), more frequent in women, occurs an average of 7 years later than MFTO, at an average age of 70 years. Instability is often severe. 72% of cases develop clinical valgus deformity of 10 degrees to 20 degrees after an average of 13 years. Recurvatum is also possible. The combination of femoropatellar osteoarthritis, generally lateral, is observed in 23 to 41% of cases, depending on the author, while osteoarthritis of the hip is observed in 10% of cases and chondrocalcinosis is present in 20% of cases. These figures must be interpreted in relation to the usual ageing of the subjects.
股胫内侧骨关节炎（MFTO）的特征是病情逐渐恶化，十分之六的病例在10至15年后无法行走。在手术阶段，前后位X线片显示胫骨内侧平台边缘的软骨下骨磨损，伴有胫骨外侧脱位，而侧位片显示胫骨内侧平台倾斜度可能超过10度，并伴有胫骨前半脱位，甚至前交叉韧带断裂。股胫外侧骨关节炎（LFTO）在女性中更为常见，平均比MFTO晚7年出现，平均发病年龄为70岁。不稳定情况通常较为严重。72%的病例在平均13年后会出现10度至20度的临床外翻畸形。也可能出现膝反屈。根据作者不同，23%至41%的病例会出现股髌关节炎，通常为外侧，10%的病例会出现髋关节炎，20%的病例存在软骨钙质沉着症。这些数据必须结合受试者的正常衰老情况来解读。
