CalciŞc periarthritis in the distal femur is a rare condition. Forty two year old Asian male visited to theoutpatient clinic of orthopedic department with acute excruciating knee pain. The arthroscopic posteriorcruciate ligament (PCL) reconstruction was performed 20 years ago with the bonepatellar tendon-bone(BPTB) autograft combined with Trevira (polyethylene terephthalate) artiŞcial ligament. Severe tenderness was noted incidentally over the medial epicondyle area of the distal femur which the cancellousscrew was inserted for PCL reconstruction, without any preceding trauma history or medial joint linetenderness due to degenerative change. The poorly deŞned calciŞc deposition was found in plainradiograph. The arthroscopic debridement of the calciŞcation and screw removal from the distal femurwas performed due to resist to conservative treatment with analgesics. After operation, the symptomswere resolved completely. The arthroscopic debridement of calciŞc periarthritis should be considered inspeciŞc cases, such as refractory cases with conservative management during 4e6 weeks. We present thearthroscopic treatment of the symptomatic calciŞc periarthritis on distal femur after PCL reconstructioncan be effective.
