Microfracture With/Without Collagen Augmentation in Patients Undergoing High Tibial Osteotomy
Effects of Microfracture With/Without Collagen Augmentation in Patients Undergoing High Tibial Osteotomy: A Randomized, Controlled, Double-Blind Trial

Detailed Description
CartiFill™ (atelocollagen, Sewon Cellontech, Seoul, Korea) was developed to to provide a matrix stability and to maintain the blood clot in the defect site, which promoted the cartilage regeneration by mesenchymal stem cell . It was a atelocollagen, highly purified porcine derived type collagen І that has been modified to virtually eliminate the risk of rejection by removal of telopeptide.
The investigators randomized patients undergoing HTO in combination with microfracture to receive either microfracture alone (control group, n = 5) or microfracture with collagen augmentation (experimental group, n=6). At postoperative one year, the clinical outcome in terms of Visual Analogue Scale of pain level (VAS), Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) score, and Tegner scores were evaluated. In addition, second look arthroscopic examination and biopsy of regenerated cartilage were carried out when the HTO plate was removed at postoperative one year. Biopsy specimens were graded by International Cartilage Repair Society Visual Assessment Scale (ICRS II scores). Finally, radiologic outcome in terms of Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scores was assessed using follow up MRI undertaken at postoperative one year.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Microfracture with Collagen Augmentation in HTO
Two groups, either collagen augmentation or not.
Firstly, all patients underwent an arthroscopic examination and microfracture for bone marrow.
Collagen augmentation included Cartifill insertion after arthroscopic microfracture.
