A Study on the Functional Outcome of Microfracture with Application of Bioactive Hyaluronic Acid as Scaffold on Patients with Osteochondral Defects of the Knee

Romuel Rabara, MD

Background: The articular surface of the knee joint is lined by hyaline cartilage which provides lubrication, aids in load bearing and decreases friction. Osteochondral defects are lesions seen at the articular surface which causes pain and discomfort. Several techniques have been developed over the years and microfracture with application of a Hyaluronic Acid mesh as scaffold is one of the most commonly used procedures to treat these injuries. 


Design: This is a case series which aims to determine the functional outcome of microfracture with application of hyaluronic acid mesh as scaffold for patients with OCD of the knee


Methods: This study is conducted at V. Luna Medical Center from 2017-2020 which included 22 patients with OCD of the knee, subjected to microfracture with application of hyaluronic acid scaffold and then enrolled in a post-operative rehabilitation protocol for at least 6 months and functional outcome was evaluated using Knee Injury and Osteoarthritis Outcome Scoring. 


Results: The lowest KOOS is observed in the restoration of the patients’ sports and recreational capabilities. Better scores were mostly seen on younger subjects especially on pain, symptom and activity of daily living. Overall functional outcome was satisfactory given that subjects had no to low pain and symptoms and are able to perform regular activities of daily living.


Conclusion: Results determined that microfracture with application of a hyaluronic acid mesh is safe and satisfactory procedure in treating osteochondral defects of the knee providing good overall functional outcome post operatively.
