Abstract

30 patients with diseased hips were treated with uncemented total hip replacement with a 36 mm femur head using a ceramic on ceramic bearing at a tertiary care hospital.

Patients aged 30 years and above were included in the study with the oldest patient being 75 years. The most common indication for surgery was secondary osteoarthritis of the hip joint due to avascular necrosis of the femur head (21 patients). Other causes were primary osteoarthritis of the hip(3 patients),intermediate stage of avascular necrosis of femur head which had not progressed to the stage of osteoarthritis (2 patients), osteoarthritis post old history of  trauma(2 patients) , osteoarthritis  post  healed  tuberculosis of  the  hip(1 patient), and  ankylosing spondylitis (1 patient) .

A thorough clinical and radiological examination was performed. All the patients were advised to do isometric quadriceps exercise 8 hours after surgery. Patients were made to sit up on 1st post-operative day and adviced knee bending exercises. Patients were made to stand up and walk on 1stpost-operative day non weight bearing or partial weight bearing as tolerated. Sutures were removed on 12th post operativeday. Average duration of stayin hospital was 5 days. The duration of follow up was till 18 months. Patients were assessed by the modified Harris Hip Score and WOMAC score after 12 and 18 months post op. All the patients were followed up regularly, no patients were lost for follow up.There was no complication during the period of study.

The mean Modified Harris Hip Score increased significantly from 26.6 pre operatively to 89.3 post operatively at 12 months and 90.0 at 18 months.

The mean WOMAC score has decreased significantly from 70.5 pre operatively to 14.8 post operatively at 12 months and 14.2 at 18 months.

This proves that uncemented total hip arthroplasty done with a 36 mm femur head and a ceramic on ceramic bearing gives excellent results.
