We assessed the use of woven carbon fibre pads to resurface osteochondral defects in animals and in patients. The pads became filled with structurally strong and compliant fibrous tissue and did not provoke a synovial reaction, though pigmentation was induced in some animals. Of the patients, 77% had a satisfactory response to resurfacing, with no synovitis. Our initial experiments indicate that carbon pads may provide a satisfactory treatment for localised articular defects.

The suppression of the immediate postmeniscectomy synovial reaction by a potent prostaglandin inhibitor (flurbiprofen 400 mg daily) resulted in significantly less knee pain and swelling in 50 patients compared to 50 age-matched controls taking a simple analgesic (paracetamol 4 g daily) (P less than 0.001), thus enhancing recovery by three to four weeks. In the patients undergoing partial meniscectomy knee function was restored by 27 days, a figure comparable with endoscopic methods.
