Abstract
Introduction: High tibial osteotomy (HTO) is a well-established procedure for treatment of unicompartmental osteoarthritis of knee. HTO is a favoured choice of treatment for isolated unicompartment arthritis in patients who are aged less than 60 years. The biomechanical rationale for HTO in patients with unicompartmental osteoarthritis of knee is unloading of the involved joint compartment by correcting the malalignment and redistributing the stresses on the knee joint .The factors associated with good long-term results include: tibiofemoral angle > 8 valgus, body weight no > 132% of ideal body weight, age < 60 years, purely unicompart mental arthrosis, ligmantous stability, pre-operative range of motion knee > 900&Ahlbak's grade 1 & 2.
Method: This prospective study of 32 patients was conducted in the department of orthopaedics at govt. Medical college, Jammu from May 2016 to December 2018, who satisfy the inclusion criteria.
Result: In our study 13 patients (40.63%) had excellent results, 18 (56.25%) had good results and 1(3.12%) had fair results. None of the patients in our study had poor results. Out of 32 patients 7 (21.88%) were males and 25 (78.12%) were females, the age of patients ranged from 42 to 57 years. the average range of motion of the involved knee in pre-operative period was 131.56 degree with range of 100-150 degree, With improvement in ROM at the final follow-up was 133.9 degrees with a range from 110 to 150 degrees. The pre-operative HSS score ranged from 56-72 with a mean of 63.312, at follow-up of 9 months HSS ranged from 69-89 with a mean of 83.46. There was an average increase of 20.01 in the score at final follow-up.
Conclusion: High tibial osteotomy is a safe, reliable procedure in unicompartmental osteoarthritis of knee. There is significant improvement in the pain and function which allows the patient to squat and sit cross legged which is very important in our community for social and religious activities. It is a valuable option in our community where majority of patients are unwilling for unicompartment or total knee arthoplasty.
