Introduction: Knee osteoarthritis is a common and disabling degenerative condition. The aim of the treatment is to reduce the stress on one compartment of the knee. Our objective was to evaluate the anatomical and functional results of surgical treatment of axial deviations in Togo.
Patients and Methods: This is a retrospective study over 12 years with a descriptive component. It included 43 patients (55 knees) who underwent internal opening-wedge or lateral closing-wedge osteotomy of the proximal tibia (PTO) in the five hospitals in Togo. The evaluation of functional results was subjective and objective with the IKS function and examination score, the Lyshom Tegner score and the Tegner Rating. Survival was evaluated by considering the indication for knee prothesis as failure.
Results: There were 28 women and 15 men whose average age was 46.39 years [18-70]. The Alhback Stage was distributed as follows: Stage I at 42.11%, Stage II at 15.79%, Stage III at 39.47% and Stage IV at 2.63%. 30 (PTO) of internal opening, 10 (POT) of lateral closing-wedge and 3 internal closin-wedge were carried out. The average follow-up was 94.50 months (8-168) or 7 years and 10 months. The patients were 91.89% satisfied with the intervention. Scores averaged 79.77 [35-100]. (35-100) for the IKS exam, 85.41 [40-100] for the IKS function, and 84.84 [29-100]. for the Lyshom-Tegner. Tegner's average rating was 3.74 [1-7].
Conclusion: With a follow-up of 8 years, we found excellent functional results. The survival rate was excellent although this remains to be qualified, although knee prothesis is available, it remains difficult to access in Togo. These results can be improved by taking preoperative health and diet measures.
