Platelet-rich plasma (PRP) injections significantly improved knee function in young patients with chondral lesions compared to hyaluronic acid (HA). PRP demonstrated superior outcomes on WOMAC and VAS scores up to 12 months post-treatment.
Area of Science:
- Orthopedics
- Regenerative Medicine
- Sports Medicine
Background:
- Chondral lesions in young adults without arthrosis present a significant clinical challenge.
- Conservative treatment options are continuously being evaluated for efficacy.
Purpose of the Study:
- To compare the clinical and functional outcomes of hyaluronic acid (HA) versus platelet-rich plasma (PRP) for treating knee chondral lesions in young patients.
- To evaluate the effectiveness of HA and PRP in improving patient-reported outcomes.
Main Methods:
- A prospective study involving 30 young adult patients with knee chondral lesions.
- Patients received either HA or PRP injections as conservative treatment.
- Clinical and functional outcomes were assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and visual analog scale (VAS) at a minimum 12-month follow-up.
Main Results:
- The PRP group showed significant improvement in WOMAC scores across all evaluated points, while the HA group did not.
- The PRP group demonstrated VAS score improvement in all aspects, whereas the HA group showed improvement at 6 and 12 months.
- PRP treatment resulted in superior WOMAC and VAS scores compared to HA treatment up to 6 months post-intervention.
Conclusions:
- Platelet-rich plasma (PRP) application yields better clinical and functional outcomes for young patients with knee chondral lesions compared to hyaluronic acid (HA).
- These positive outcomes associated with PRP were sustained for up to 12 months.
- PRP represents a promising therapeutic option for managing knee chondral lesions in this patient population.
