Abstract
Objective: To determine the frequency of different outcomes of uncemented total hip replacement in young patients with avascular necrosis due to traumatic cause
Materials and Methods: This study was done in Khyber Teaching Hospital Peshawar, Pakistan from March 2022 to January 2024. 96 patients of the younger age group (20-45 years) consisting of both genders with uncemented total hip arthroplasty for AVN femoral head due to traumatic cause, were studied. Age, gender, side of hip affected by AVN, and pre-operative Harris Hip Score were noted. Functional outcomes of uncemented THA were determined in terms of improvement in postoperative Harris hip score was documented at 3 months postoperatively.
Results: A total of 96 patients, 80 (83.33%) men and 16 (16.67%) women underwent uncemented total hip arthroplasty. The age ranged from 20 to 45 years, with a mean of 40±7.02 years. Reasons for osteonecrosis included femoral neck fracture (50%), hip dislocation (36.46%), and acetabular fracture (13.54%). After 3 months of surgery, the Harris hip score improved and was excellent in 86.46% of patients, good in 8.33% of patients, fair in 5.2% of patients and none of the patients had poor scores.
Conclusion: The cementless hip prosthesis for the treatment of post-traumatic avascular necrosis of the femoral head in active and young individuals is a very good option. The results of cementless hip arthroplasties are good and encouraging in terms of functional outcome postoperatively.
