The surgical technique and the age of the horse both influence the outcome of mosaicplasty in a cadaver equine stifle model.
Abstract: Six pieces of grafts, 6.5 mm in diameter, 20 mm in length, were taken from each of 170 cadaver hindlimbs, using the cranial surface of the medial femoral trochlea for harvesting. The age of the horses varied between 4 months and 23 years. 30 limbs under the age of 12 years were selected for transplantation. Three of six grafts were transplanted into the medial femoral condyle using different combinations of tunnel depth and dilation. With ageing, a significant decline in transplantability was detected. In general, mosaicplasty cannot be recommended in horses above 11 years. Based on a previous clinical case (Bodó et al., 2000), a good surface alignment was indeed achieved with a combination of graft length drilling and dilation in most cases. However, the occasional entrapment of cartilage debris under the graft prevented perfect alignment in the present cadaver study in 27% of the grafts transplanted in this manner. Since the protrusion of grafts never exceeded 1.5 mm, we conclude that drilling 3-5 mm deeper than graft length with graft length deep dilation can avoid disadvantageous protrusion of the transplanted hyaline cartilage caps, achieving bone decompression at the same time.

This study investigates how surgical methods and the age of the horse both influence the results of a surgical technique called mosaicplasty in a dead horse joint model. The results suggest that the older the horse, the lower the success rate of the transplant procedure, and that the procedure may not be recommended for horses over 11 years old. In addition, it was discovered that a combination of graft length drilling and dilation frequently achieved a good surface alignment, although in some cases, cartilage debris obstructed perfect alignment.
Research Methodology
- The researchers used 170 cadaver hind limbs from horses aged between 4 months and 23 years.
- Six grafts were taken from each limb, each 6.5 mm in diameter and 20 mm long, from the cranial surface of the medial femoral trochlea.
- They then selected 30 limbs of horses under 12 years old for transplantation.
- Three out of six grafts were implanted into the medial femoral condyle using different combinations of tunnel depth and dilation.
Results and Findings
- They noticed a significant decline in transplantability with the ageing of the horses. Because of this, they do not recommend mosaicplasty in horses over 11 years old.
- Based on a past clinical case, good surface alignment was achieved with a combination of graft length drilling and dilation. However, perfect alignment was prevented by cartilage debris in 27% of the cases.
- The researchers concluded that drilling 3-5 mm deeper than the graft length, with graft length deep dilation, can avoid the protrusion of the transplanted hyaline cartilage caps and achieve bone decompression at the same time.
Significance of the Findings
- The study provides valuable insight into how the age of the horse and the surgical technique impact the outcome of mosaicplasty.
- The findings can guide surgeons in deciding the best techniques and methods to apply in different age groups of horses.
- The recommendations on drilling depth can help prevent cartilage protrusion, which can potentially enhance the success rate of the procedure.
