INTRODUCTION: Intra-articular platelet-rich plasma (PRP) injection therapy has been extensively applied in clinical practice to treat musculoskeletal disorders such as osteoarthritis, but the treatment for haemophilic arthropathy is rarely reported.
AIMS: This study aimed to compare the efficacy of intra-articular PRP vs hyaluronic acid (HA) injections in treating haemophilic arthropathy of knee joints.
PATIENTS: Twenty-two haemophilia patients (mean age, 41.1 ± 1.7 [range, 20-50] years) with painful haemophilic arthropathy of the knee were enrolled for this open-label and observer-blind study.
METHODS: Eleven patients were treated with a single intra-articular injection of PRP and the other 11 received five consecutively weekly intra-articular injections of HA. Outcome assessment included pain by visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Chinese Version and synovial change determined by ultrasonography.
RESULTS: Platelet-rich plasma and HA intra-articular injection showed statistically significant reduction in VAS, WOMAC total score and hyperaemia score from baseline to 6-month post-treatment. Inter-group comparison showed statistically significant difference in the change in VAS score, WOMAC pain score, physical function score and total score at 6 months, wherein PRP group showed sustained beneficial effect than HA group at 6 months.
CONCLUSION: Our study demonstrates that, in comparison with five weekly injections of HA, a single PRP injection resulted in better improvement in pain relief and knee joint function, and greater reduction in synovial hyperaemia for up to 6 months. Our results suggest that PRP may be practical and effective for haemophilic knee arthropathy, and further investigation is warranted.
