Assessment of Anterior Cruciate Ligament (ACL) Degeneratio Mucosa Treatment

Study Overview
=================
Brief Summary
-----------------
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.
