Abstract
Background: The success of knee arthroplasty is closely linked to post operative range of motion .The presence of fixed deformities pre operatively may have an adverse effect on the same .This study aims to assess the relationship between sagittal and coronal plane deformities with post operative range of motion following knee replacement in Indian patients
Materials and methods: The study included 354 primary total knee replacements among 254 patients which were operated at a rural teaching hospital in india. The patients were followed up for a minimum duration of 6 months, with a maximum follow up of 2 years. The range of motion was noted at consecutive visits and the results were statistically analysed to assess any difference in the patients with pre operative fixed deformities (saggital of coronal).
Results: The mean age was 63.8years with a range of 50 – 80 years with 50.8% of patient in 60 – 69 year age group.Fixed flexion deformity ranged from 0 – 40 with a mean of 10.5 and SD of 10.9. Varus deformity ranged between 0 – 30 with mean of 11.8 and SD of 6.1. Valgus deformity also ranged between 0 – 30 with mean of 12.6 and SD of 10.6.The fixed flexion deformity had a negative correlation with the postoperative range of motion preoperatively(r-0.64) , at 3months(r-0.56) , at 6 months(r-0.53) , at 1 year(r-0.67).however at 2 years there was no correlation (r -0.45).Varus deformity , valgus deformity , mediolateral and anteroposterior instability posterior tibial slope had no correlation with postoperative range of motion at all the points of follow up.
Conclusion: Corronal plane deformities (valgus or varus) had no correlation with the post operative range of motion . the presence of fixed flexion deformity had negative correlation at initial follow up , however at one year follow up there was no difference . We can conclude that the presence of these fixed deformities should not lead to a significant impact on range of movements after knee replacement
