He has had an MRI where a medial meniscal tear was found and after a knee arthroscopy the diagnosis of crystal deposition arthritis was established. The symptoms did not subside and then he had another arthroscopy, where a large fatty mass in the suprapatellar area was found and excised. Pathology report established the diagnosis of a lipoma arborescens.
