Tibial osteotomy for the knee joint osteoarthritis

Abstract EN

This is a prospective study on 100 knee joints in 98 patients of the knee, treated by modified valgus dome shaped osteotomy of the proximal tibia.

The distal part of the osteotomy pushed anteroproximal to decompress the patellofemoral joint .

Age of the patients was between 55 to 70 years.

The amount of involvement of the knee compartments were assessed preoperatively by anteroposterior (AP), lateral, tunnel and merchant view.

Arthroscopy was necessary for loose body removal in 3 patients.

No permanent device for fixation was used, so it was possible to change the angle of osteotomy by weding the cast postoperatively for adjusting the alignment.

A simple rod was used, to align the anterior superior iliac spine (ASIS) and center of patella with the medial aspect of the first metatarse.

After osteotomy the patients were allowed to have a full weight bearing (WB) with a well molded long leg cast as early as convenient.

There was one non-union of the tibia which followed impending compartment syndrome.

After this treatment %63 of the patients can do more daily activities and their range of motion (ROM) improved, % 17 gained improvement in their ROM and relieve of pain in their daily activities, % 15 feel some improvement in their pain but they need to use medications and in 5 % no improvement was gained.
