Patient Data

Age: 25 years

Typical mensical appearance with bony tunnels anteriorly and posteriorly (arrows) containing sutures attached to the medial tibia by a metallic screw. Note articular cartilage is intact.

Case Discussion

Meniscal transplantation is technically difficult, as it must be correctly sized, placed accurately on the tibia and tightly secured to the tibial plateau.  A major issue is this attachment varying from tunnelled sutures (as in this case) to metallic fixation of bone plugs attached to the graft mensicus.  In this case the mensicus has also been sewn peripherally onto the medial capsule.

In general meniscus transplantation is only performed in meniscus deficient patients if they are young and articular cartilage is preserved.  The residual native meniscus is trimmed away prior to placement of the transplant.
