To investigate the value of proximal fibular osteotomy in the preliminary clinical efficacy of senile and high-risk knee osteoarthritis.

Data of fourty-five patients (fourty-eight knees) with knee osteoarthritis with inner lateral chambers pain as the main manifestation were admitted and treated from April1 2015 to January 31 2018. The average age is 78±3 years. All patients were underwent proximal fibular osteotomy. The hospitalization days, operating time, blood loss, postoperative complications and VAS, KSS knee score were recorded at preoperative 2 days, 3 months and 6 months after operation. The value of radiographic assessment and change of height of the inner and outer chambers of the knee were compared.

The hospital stay days was (4.0±2.4) d, the unilateral operation time was (33.3±8.4) mins and the intraoperative blood loss during the operation was (20±8) ml. No complications such as wound infection, delayed healing and nerve injury occurred after operation. Compared with preoperative, VAS scores were decreased at 2 d, 3 and 6 months after surgery (F=93.248, P<0.05), and KSS clinical scores were increased (F=68.621, P<0.05), KSS function. The score was increased (F=56.362, P<0.05), and the difference was statistically significant. At the last follow-up, 45 patients (48 knees) had an increased patellofemoral angle from 83.2±2.1° to 84.0±2.3° (t=-2.110, P<0.05); the height of the lateral space of the knee joint was reduced from 0.75±0.10 cm to 0.68±0.115 cm before operation (t=5.473, P<0.05).

Proximal humerus osteotomy is an effective method for the treatment of varus knee osteoarthritis in high-risk patients.
