“…Therefore, the sheep model appears to mirror the results we obtained in the present clinical study, in that incongruities ranging from flush to countersinking of less than 1 mm can be tolerated for autografting. Terukina reported that the average thickness of the cartilage in cadaver knee joints was 1.69 mm (range, 0.22-3.65 mm) [22]. If countersinking of an articular cartilage graft is less than 1 mm, then remodeling may be expected to occur because the graft plug and its surrounding tissue will be in contact with each other in the human knee joint.…”

Although grafted osteochondral plugs should ideally have a smooth surface for mosaicplasty, surface incongruity is sometimes evident at the time of surgery. There may be no problem if there is depression of the grafted plugs, but graft protuberance may have an adverse effect. We studied five knees in five patients who had incongruity (protuberance or depression) of grafted osteochondral plugs at the time of mosaicplasty. The mean age at surgery was 36.6 years (range, 15-65 years), and the mean follow-up period was 32.9 months (range, 24-49 months). All patients underwent second-look arthroscopy after a mean post-surgical period of 14.8 months (range, 3-18 months). We divided the cases so that there were two in the protuberant group (P) and three in the depressed group (D). In P, all patients had a catching sensation about 4 months after surgery, and sometimes pain in the knee joint. Second-look arthroscopy revealed fissuring of the plugs and fibrillation around the recipient site. In D, there were no symptoms due to the depressed plugs. Second-look arthroscopy showed that the depressed areas were covered with fibrocartilage-like tissue, and that the joint surface was smooth. In conclusion, our clinical results and second-look arthroscopic evaluation suggest that isolated osteochondral plug depressions of not greater than 1 mm could still promote acceptable cartilage healing leading to good clinical outcomes. However, plug protuberance at mosaicplasty should always be avoided.

“…20,26 The variation in thickness of articular cartilage from the human knee has been mapped using cadaver tissue 27 and by arthrography. 28 The high loads transmitted through the patellofemoral joint and the resulting thick retropatellar articular cartilage support the theory that cartilage is modelled in response to mechanical load.…”

The weight-bearing status of articular cartilage has been shown to affect its biochemical composition. We have investigated the topographical variation of sulphated glycosaminoglycan (GAG) relative to the DNA content of the chondrocyte in human distal femoral articular cartilage.Paired specimens of distal femoral articular cartilage, from weight-bearing and nonweight-bearing regions, were obtained from 13 patients undergoing above-knee amputation. After papain enzyme digestion, spectrophotometric GAG and fluorometric DNA assays assessed the biochemical composition of the samples. The results were analysed using a paired t-test.Although there were no significant differences in cell density between the regions, the weight-bearing areas showed a significantly higher concentration of GAG relative to DNA when compared with non-weight-bearing areas (p = 0.02).We conclude that chondrocytes are sensitive to their mechanical environment, and that local loading conditions influence the metabolism of the cells and hence the biochemical structure of the tissue.

“…To harvest the grafts in arthroscopic procedure, peripheral parts of medial femoral condyle must be the first choice of donor site ( Fig. 1) because filling the joint with fluid in arthroscopic procedure, causes the lateral movement of patella [12,13]. In the graft harvesting step, introducing the tubular chisel perpendicular to the donor site is important.…”

Analysis of the thickness and curvature of articular cartilage of the femoral condyle

Abstract: When the chondral lesion is assumed at the weight bearing area of the medial or lateral femoral condyle, the anterior portion of the sulcus terminalis (the groove for meniscus) in the middle section of the lateral condyle is considered to be the optimal donor site.
