Calcific deposition in the lateral collateral ligament of the knee joint is a rare condition. The present study reports the case of calcific deposition involving the lateral femoral condyle eroding the bone cortex without trauma. A 58-year-old woman presented with pain emanating from the lateral aspect of the left knee joint that began 2 months earlier. The patient’s symptoms persisted despite the use of anti-inflammatory medication for more than 2 months. The calcific deposits were removed using an arthroscopic procedure. There have been relatively few reports of arthroscopic removal of calcific deposits. Conservative management is the first-line treatment for calcific deposition. If long-term conservative treatment fails, removal of calcific deposits from the lateral collateral ligament can relieve the symptoms of persistent pain and erosion of the lateral femoral condyle.
