Abstract

|
|
Thirty-nine patients (forty-two knees) with osteochondral defect of the knee were treated by the abdrasion arthroplasty and carbon arthroplasty. The thirty nine patients consisted of nineteen females and twenty males ranging in age from 35 to 76
years
(mean, 48 years). The mean follow up period was 15 months (range, 6 months to 17 months). Abrasion arthroplasty was performed in patients with osteoarthritis.
Satisfactory result could be obtained in patients with 2 cm or smaller osteochondral defect.
Carbon fibers have many attrations. In its pure from, it is chemically inert ant biocompatible with the environment of the knee, and induces an abundant collagenous fibirous tissue organized around and along the carbon fibers.
Many of the patients demonstrated an excellent recovery process, e.g. the quickly become able to move without pain.
I employed arthroscopy for 2 to 12 months after surgery in 6 patients and found that very few rods or pads were still visible in 6 months after implantation. I have seen no evidence of disintergration in any of the pads of rods, or migration of
carbon
fiber debris into the joint space or the surrounding tissues. The carbon fiber arthroplasty appears to be appropriate in the surgical management of grade II articular cartilage defects (i.e., erosion of the aricular cartilage down to the
subchondral
bone) in the painful knee.
