Opening the Knee Joint to Look Inside

Rhode Island rates for HCPCS 27331

The knee joint is opened through an incision so the inside of the joint can be examined directly. A tissue sample may be taken and loose fragments of bone or cartilage or foreign material removed at the same time. It is used when the cause of pain, swelling, catching, or locking needs to be identified and dealt with.
