In that case, mucoid degeneration can be extruded from the ligament and will be removed in the saline flow. ACL (anterior cruciate ligament) mucoid degeneration means the lesion of the ACL. proposed a different intervention called reduction plasty, whereby the hypertrophic ACL is reduced to normal size without excision of all mucoid substance [17]. Ever since mucoid degeneration of the anterior cruciate ligament (MD-ACL) was named by Kumar et al. 2009. Magn Reson Imaging Clin N Am. Unlike meniscal tears and chondral defects, the mucoid degeneration of the anterior cruciate ligament (ACL) is a rare cause of knee pain and there have been no case reports of mucoid degeneration of both the ACL and the posterior cruciate ligament (PCL).

Mucoid degeneration (MD) of the anterior cruciate ligament (ACL) is a benign knee pathology, which is often indicated for surgical treatment if symptomatic. volume33, Articlenumber:26 (2021) As there was no control group in any of the studies and the natural history of MDACL is not known, the postoperative improvement may have been attributed to the placebo effect, simultaneous arthroscopic procedures or the postoperative rehabilitation, or may be due to the pain having resolved without treatment at all. On physical exam, the Lachman test for ACL instability is negative with an ACL ganglion. Arthroscopy 24(6):642649.
