Rising Incidence of Avascular Necrosis in Younger Patients: Clinical Outcomes and Management Approaches Through Total Hip Joint Endoprosthesis

Avascular necrosis (AVN) of the femoral head is increasingly acknowledged as a major contributor to early deterioration of the hip joint, especially in younger persons. Historically tied to older demographics and severe osteoarthritis, avascular necrosis (AVN) is now increasingly observed in adults under 60, typically associated with steroid consumption, alcohol misuse, or metabolic conditions. This study analyses the clinical results of total hip arthroplasty (THA) in patients with avascular necrosis (AVN), use data from a cohort of 82 individuals treated from 2022 to 2024 at the Surkhandarya Regional Multidisciplinary Medical Centre in Uzbekistan. Within the study cohort, 24 patients (29.3%) were diagnosed with avascular necrosis (AVN) as the principal reason for surgical intervention. The average age of these patients was 52.6 years, much younger than those with osteoarthritis or post-traumatic arthritis. All AVN patients participated in early mobilisation protocols within 24 hours post-surgery and were assessed using the Harris Hip Score and SF-36 health assessment at three and twelve months postoperatively. Findings indicated significant enhancements in joint functionality and overall quality of life, akin to results observed in older individuals with degenerative disorders. Younger patients, however, indicated a more significant emotional impact preoperatively and had heightened expectations for physical performance and return to work. Early rehabilitation was crucial in fulfilling these expectations, resulting in elevated satisfaction rates. The increasing incidence of AVN in younger adults highlights the necessity for prompt diagnosis, risk factor management, and customised postoperative care. THA, when integrated with structured therapy, continues to be a useful approach for recovering mobility and enhancing quality of life in this developing patient demographic.
