EVALUATION OF JOINT CONVERGENCE ANGLE AFTER PROXIMAL FIBULAR OSTEOTOMY IN OSTEOARTHRITIS OF KNEE

Dr. Ashok Vidyarthi and *Dr. Mayank Pratap Singh

ABSTRACT

The aim of this was to study the effect of PFO on the predominant medial compartment osteoarthritis knee. In a period of one year, 40 patients with predominant medial compartment osteoarthritis were operated in our department of orthopaedics. 2cm long fibula was resected 7 cm to 9 cm distally from the head of fibula. In our study, the average age of presentation was 64.1 year. The outcome was evaluated radiologically by using JCA. Follow up was done according to set proforma. At final follow up JCA improved to 3.13+ 1.223 degree from 1.3+ 0.853 degree preoperatively(both values were significant P<0.001). It was concluded that PFO is a new and cost effective surgery for predominant medial compartment osteoarthritis of knee with obvious opening of the joint space and correction in varus angulation of the knee.
