The Effectiveness of the Microfracture Technique in the Meniscal Healing

Study Overview
=================
Brief Summary
-----------------
Meniscus injuries are a very common cause of knee pain. The meniscus is a semilunar fibrocartilage structure found on the medial and lateral sides of the knee. The meniscus serves to absorb impact and protect the articular cartilage during weight-bearing activities, joint stability, proprioception, and nutrition. This has a significant effect on knee biomechanics. After the menisci are injured, the biomechanics of the knee change so that degenerative changes occur more frequently in the tibiofemoral compartment. Improvement of tibiofemoral arthrosis after meniscectomy surgery has been demonstrated in several long-term clinical studies. With increasing awareness of the importance of the meniscus in knee biomechanics, various meniscus repair techniques have been developed. In addition, several adjuvants for healing have been proposed to enhance meniscus healing. However, a study showed the meniscal repair failure rate increased from 22% to 24% at 5 years. Study found the healing rate of meniscus repair, which was accompanied by ACL repair, had a greater healing rate, 93% vs. 50%. Hemarthrosis that occurs after bony tunneling during ACL reconstruction provides a fibrin clot and an environment rich in factors that promote healing of the newly repaired meniscus. The fibrin clot provides the structural foundation for meniscus healing. Transmission factors, such as fibronectin and growth factors, are also present. Microfracture is a common procedure used for the treatment of damage to the articular cartilage in the knee. This procedure is used to stimulate the production of fibrocartilage in areas of injured cartilage. Microfractures are performed by creating 1 or more small channels (1 to 3 mm in size) that pierce the subchondral bone and release bone-forming components into the joint. Microfractures serve to promote the formation of fibrocartilage over damaged cartilage. Research in 2016 used an animal model (Capra hircus) to investigate the effectiveness of the microfracture technique on meniscus tear healing rates. They found significant healing in meniscal repair accompanied by microfracture technique (65% vs 12%). However there is still not enough research regarding the efficacy of microfracture in meniscal healing, especially among Indonesian. Therefore, the investigators aim to investigate its efficacy.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Healing Rate | Healing Rate, Investigated by MRI and Arthroscopy | 3 months | 
| Healing Rate | Healing Rate, Investigated by MRI and Arthroscopy | 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functional Outcome | Functional Outcome assessed with IKDC ScoreFunctional Outcome assessed with IKDC Score. The higher the score, the higher the level of function and the lower the level of symptoms. A score of 100 suggests no limitation with activities of daily living or sports activities and the absence of symptoms. | 3 months |
