ABSTRACT
PURPOSE:
Bony resection of the proximal medial tibia, an alternative technique for soft tissue balancing in total knee arthroplasty (TKA), was compared to the conventional medial soft tissue release technique. MATERIALS ANDMETHODS:
From June 2005 to June 2007, we performed 40 TKA in 27 patients with > or =10degrees tibio-femoral varus deformity. The conventional, medial soft tissue release technique was applied in 20 cases and bony resection of proximal medial tibia in the other 20 cases (vertical osteotomy group). Total operation time, knee range of motion (ROM), hospital for special surgery (HSS) scores, and tibio-femoral medial-lateral gap ratio in 0degrees, 90degrees, and 130degrees flexion at postoperative 6 months were compared between the groups.RESULTS:
The total operation time was shorter in the vertical osteotomy group. Tibio-femoral medial-lateral gap ratio in 130degrees flexion was closer to 1 in the vertical osteotomy group (p=0.000). There was no significant difference in the ROM, HSS score, or tibio-femoral medial-lateral gap ratio in 0degrees and 90degrees flexion at postoperative 6 months.CONCLUSIONS:
In severe varus knees, bony resection of proximal medial tibia can be considered as an alternative technique, in order to decrease total operation time and to obtain medial-lateral, soft-tissue balance in deep flexion.
