Mucoid degeneration of the anterior cruciate ligament (ACL) is mostly observed in middle-aged patients with knee pain and limited range of motion. Close. However, the terminal ROM achieved after debulking MD-ACL was significantly better (p<0.05) at 2years of follow-up as compared with the group that did not undergo debulking. Lippincott-Raven; 1997. This was confirmed at 2years follow-up, when the patients who underwent debulking showed a statistically significant improvement in in mean terminal flexion by 21.51 in group B (mean pre-operative: 96.3855.78; mean post-operative: 117.892.64) as compared with 5.02 in group A (mean pre-operative: 98.0934.79; mean post-operative: 103.114.1). b Open debulking of mucoid ACL under direct vision using 15-number blade.

It provides objective end points for open debulking of mucoid ACL in these patients and, being a multicentric study, it entails external validity of this procedure in a diverse population. The most common mechanism is that of a sudden pivoting or cutting maneuver during sporting activity, which is commonly seen in football, basketball and soccer. If left untreated, a small ACL tear will increase in size, causing more pain and increasing the laxity in the knee.
