[A short term clinical study of fibular osteotomy for knee osteoarthritis].

OBJECTIVE

To study clinical effects of fibular osteotomy for the treatment of knee osteoarthritis.

METHODS

From January 2015, 12 patients (15 knees) with knee osteoarthritis were treated with fibular osteotomy. The main symptom was interval inside pain. All the patients were female with an average age of 61.3 years old. Early postoperative ambulation of joints was carried out after surgery, and the corresponding radiographic assessment before and after operations were performed with record. Finally, the following indicators were analyzed:VAS, KSS, HSS, respectively before, 2 days and 2 months after the operation.

RESULTS

The average hospitalization time was (6.0±2.4) days, and the time of unilateral operation was (33.3±8.4) minutes without significant bleeding. There were no obvious complications such as wound infection, delayed healing and nerve damage. All the patients could walk around 1 day after operations with a chief complaint of the obvious reduction or disappear of the interval medial knee pain. The VAS score, HSS score and KSS clinical score were significantly improved 2 days after surgery compared to the scores before operation. These above scores and functional score were significantly improved 2 months after operation compared to the scores before operation. X ray films of the weight bearing knees were taken 2 days after surgery, showing increased height of medial joint space to some extent compared to that before operation.

CONCLUSIONS

A fibular osteotomy has been proved to significantly reduce the postoperative pain and facilitate the good recovery of joint function with the advantages of simple surgical procedures and slighttrauma. Therefore, it is an effective method for the treatment of knee osteoarthritis with varus deformity.
