Why is the HemiCAP placed on the metatarsal side?


The HemiCAP implant is unique in that it is designed for the metatarsal side of the joint where the arthritic changes begin and which generally has more wear and tear on it. Other hemiarthroplasty devices replace only the end of the phalangeal side which may still have good remaining cartilage and do not address wear on the metatarsal side.
