Abstract:
Background:Avascular necrosis (AVN) of the femoral head results from intraosseous pathology causing functional impairment. Early diagnosis allows conservative treatment like core decompression, delaying total hip arthroplasty.
Objective:This meta-analysis aims to summarize platelet-rich plasma's (PRP) impact as an adjunct to core decompression (CD) on treatment outcomes and femoral head preservation in hip AVN.
Methods:The study conducted a comprehensive literature search using PubMed, Cochrane Library, Science Direct, Google Scholar and Med Line, including randomized controlled trials (RCTs) and previous meta-analyses from various databases. Using a random effects model, it compared PRP+CD with bone grafting to CD with bone grafting alone in AVN patients, evaluating function, pain scores, disease progression and the need for hip surgery.
Results:The meta-analysis examined 1041 records and included three studies. The primary outcomes were function and pain scores using Harris Hip Scoring (HHS) and Visual Analog Scale (VAS). Postoperative HHS scores at final follow-up favored the PRP+CD group significantly over CD alone. Postoperative VAS scores showed a trend towards higher scores in the CD alone group. The PRP+CD group demonstrated higher survival from disease progression compared to CD alone. Overall, the study suggests that PRP+CD led to better functional outcomes and disease progression outcomes than CD alone in AVN of the hip.
Conclusion:The PRP+CD treatment group showed significant benefits in AVN patients compared to CD alone, including higher HHS scores, improved disease progression survival and reduced need for hip surgery. Although PRP+CD resulted in decreased VAS scores, the difference was not statistically significant.
