Abstract
Introduction: Cartilage lesions pose a significant problem to surgeons, at best being replaced by poorer quality fibrocartilage post
micro-fracture. Hyaluronic acid has shown to inhibit joint degeneration and reduce joint inflammation. This study wishes to evaluate the
outcome of visco-supplementation following micro-fracture.
Material & Method: Twenty one consecutive patients with chondral lesion less than 2 sq cm were treated with micro-fracture and
post operatively randomly divide into two groups. One group was supplemented with intra-articular hyaluronic acid at 3 weeks post
surgery. The patients were followed up at 3, 6 & 12 months for WOMAC score and IKDC score.
Results: The WOMAC score and IKDC score in the visco-supplementation group were significantly better than those of the non
visco-supplementation group at 6 months (p=0.0001). At 12 months although the scores were significantly better than at 6 months,
there was no significant difference between the two groups (WOMAC p=0.86, IKDC p=0.347).
Conclusion: Hyaluronic supplementations following micro-fracture ensure an early improvement in functional scores following
micro-fracture. A longer follow up is necessary to evaluate its role in preventing further joint degeneration.
