Percutaneous Subchondral Drilling of Bones in Ostcoarthritis of Knee Joint

Background: Osteoarthritis of knee joint produces significiant functional disability. Pain is a prominent feature. It has been suggested that increased intraosseous pressure is a cause of pain and maybe responsible for production of subchondral bone. Making multiple holes into the subchondral dense bone could, therefore, decrease pain and improve function. A study was disigned to test this assumptions. Materials and Methods: 50 patients with knee osteoarthritis of knee who had consecutively referred to Baghiattalah hospital were randomly divided into two groups for management. 21 patients were treated by percutaneous subchondral drilling of osteoarthritic areas and 29 were treated by conservative management. The change in pain pattern functional status of the knee and knee rang of motion were then studied one week, two weeks, six weeks and 12 weeks after treatment. Results: From surgical group only 8 cases had improvement in their pain, and 13 obtained no benefit. 5 patients developed minor complications from surgery. The pain and limitation of motion continued in a high preccntage of surgically treated cases upto 12 weeks. The nonsurgical patients had better pain relief and improvement in their range of motion in successive visits compared to the first group. Conclusion: Subchondral percutaneous drilling for knee osteoarthritis either cannot decrease intraosscous pressure or in creased pressure is not the cause for osteoarthritic knee pain.
