Assessment of Anterior Cruciate Ligament (ACL) Degeneratio Mucosa Treatment

Anterior Cruciate Ligament (ACL) Degeneratio Mucosa is a condition resulting from mucoid degeneration of ACL. Exact etiology is unknown, however ACL Degeneratio Mucosa impairs everyday functioning. In the literature there were some reports of treatment by ACL excision and subsequent reconstruction, however such treatment brings risk of deteriorated function. In this study the investigator will evaluate the technique of ACL "decompression" by the means of longitudinal incisions and evacuation of extrafibrous mucoid tissue.

Inclusion Criteria:patients with ACL degeneratio mucosa decided to undergo a surgical treatmentrange of motion impairment caused by mucoid or cystic changes in ACL confirmed by MRIExclusion Criteria:non-adherence to the study protocolactive knee inflammationrange of motion impairment due to other extra- and intra-articular reasons
