摘要

Purpose To examine the cost-effectiveness of a series (total of 3 injections) of intra-articular platelet-rich plasma (PRP) injections in comparison to that of hyaluronic acid (HA) viscosupplementation for the treatment of symptomatic knee osteoarthritis. Methods Outcome data regarding the use of PRP or HA injections for the treatment of symptomatic knee osteoarthritis were determined from the highest-quality data (Level I) available in the literature until 2015. Health utility values were then derived from these high-quality data. Costs were determined by examining typical charges for patients undergoing a series of either PRP or HA injections for the treatment of this condition at a large private orthopaedic practice. These health utility values and costs were used to create an expected-value decision analysis model. Results The results of the model revealed that the cost per quality-adjusted life-year (QALY) of a series of PRP injections was $8,635.23/QALY and that of a series of HA injections was $5,331.75/QALY. A series of PRP injections was associated with a higher initial cost than a series of HA injections (difference, $1,433.67); however, PRP was also more effective (higher utility value) than HA by 0.11 QALYs (0.69 vs 0.58, P = .0062) at 1 year. The incremental cost-effectiveness ratio of the use of PRP injections as opposed to HA was $12,628.15/QALY. Conclusions Although a series of either PRP ($8,635.23/QALY) or HA ($5,331.75/QALY) injections for the treatment of symptomatic knee osteoarthritis would be considered cost-effective (cost per QALY < $50,000), PRP injections were not more cost-effective than HA injections. However, PRP was significantly more effective at 1 year, and being associated with an incremental cost-effectiveness ratio of $12,628.15/QALY when compared with HA, a series of PRP injections should be considered a reasonable and acceptable alternative to HA injections for the treatment of symptomatic knee osteoarthritis.
