Abstract

Background: Being a synovial joint hip can have a number of end stage diseases like primary osteoarthritis, secondary osteoarthritis, and avascular necrosis of femoral head. Total hip replacement is the ultimate treatment for end stage diseases of hip to improve hip functions and relieve pain. To evaluate functional outcome of artificial hip joint postoperatively, Harris hip score is used.

Method: This prospective study was carried out in Khyber Teaching Hospital Peshawar, Pakistan from January 2018 to January 2022. 96 patient of age group 30 years and above of both gender with total hip arthroplasty for end stage osteoarthritis of hip (both primary and secondary to trauma) and osteonecrosis who fulfilled the inclusion/ exclusion criteria were included in the study. Age, sex, site, operative indication and pre-operative Harris Hip Score were documented. Uncemented total hip replacement was done. Postoperative Harris hip score was documented at 3 months after surgery.

Results: Among total 96 patients 58.33% were male and 41.67% where females with age rang 30 to 76 years. Avascular necrosis of hip (44%), primary osteoarthritis (36%), secondary osteoarthritis due to trauma (30%), and sequel of hip infection (20%) were indication of surgery. Preoperative Harris Hip Score ranged from 20 to 50 and it ranged from 70 to 95 at 3 months after surgery. Postoperatively Harris hip score were excellent in 80%, good in 12% while fair in 8% patients. Only 6.25% cases developed complications, 2 (2.08%) skin incision site infections and 4(4.17%) dislocations.

Conclusion: Total hip replacement is an excellent function preserving and pain-relieving procedure for end stage diseases of hip joint with less number of complications.
