Abstract
Calcium apatite deposition disease (CADD) is a common entity characterized by deposition of calcium apatite crystals within and around connective tissues, usually in a periarticular location 1. Many different locations of CADD have been described amongst which, lateral collateral ligament (LCL) of the knee is a rare location 2. The first ever case of calcific deposits in the lateral collateral ligament of the knee was reported by Anderson et al 3 in 2003. A few isolated case reports of LCL calcification are published in the literature 4,5 but arthroscopic excision of calcific deposit in LCL has not been described yet in the literature. Here we are describing 2 cases of arthroscopic excision of calcific deposits in LCL of the knee by a new portal called ‘Direct lateral portal' for the knee.

Case 1- A 50-year-old lady presented with pain deposits in the lateral collateral ligament of the knee was in the left knee of one year duration
Calcific deposits in the lateral collateral ligament of the knee has been described in the literature[1,2,3,4,5].The condition is described in the middle and old age group[6].Open excision of calcific deposit has been described in the literature[7,8], but arthroscopic excision has not been described in the literature
Summary
Calcium apatite deposition disease (CADD) is a common entity characterized by deposition of calcium apatite crystals within and around. Case 1- A 50-year-old lady presented with pain deposits in the lateral collateral ligament of the knee was in the left knee of one year duration. Describing 2 cases of arthroscopic excision of calcific deposits in LCL of the knee by a new portal called ‘Direct lateral portal' for the knee. Case 2- A 54-year-old lady presented with left knee pain of 6 months duration She was treated with anti-inflammatory medications and physiotherapy. X-ray showed calcific deposits in the lateral side of the knee. MRI showed calcific deposits at the femoral attachment of LCL Since her pain interfered with daily activities, arthroscopic excision of calcific deposits was considered. The calcific deposits in LCL were visualized (Fig. 4 e)
