Arthroscopic findings of the knee and histological examination of PCL. a Arthroscopic examination from anterior view revealed yellowish crumbly tissues along the thickened PCL. Tension and bulk of the PCL were well preserved. Anterior cruciate ligament appearance and tension with probing was normal but was pushed towards lateral wall of the notch (black arrow). b The yellowish tissue was present in deeper region (black arrow) while retention of fluid was not observed within the ligament substance. c The PCL tissue was split, and evidently degenerated tissue was carefully removed while meticulous care was taken to preserve the longitudinal fiber of the PCL. MFC; medial femoral condyle. d On histologic examination of the PCL, loose fibrocollagenous tissue containing myxedematous changes indicated mucoid degeneration of the ligament (right side of a dotted line, black arrow, Hematoxylin and eosin stain)
