Although an intra-articular ganglion of the knee joint is frequently found in meniscal fibrous tissue, a ganalion of the posterio cruciate ligament (PCL) is very rarelyseen, with no cases with recurrent hemarthrosis previously reported.A 32-year-old man was admitted to our hospital complaining of knee pain, restriction of knee motion and hemarthrosis.Radiologically there were no findings in the knee joint. An arthrogram and MRI showed a cystic lenion (30mm by 16mm) on the PCL, which was suspected an being an intra-articular ganglion.At arthroscopy a cystic lesion was found on the PCL and upon pushing it with a probe, clear mucinous fluid came out.All the patient's sympotoms improved after resection of the cystic lesion under arthroscopy.However the cause of the hemarthrosis was not determined, microtrauma and a ganglion may induce bleeding of the synovial tissue.
