LINK® Sled Prosthesis Bone preserving unicondylar knee prosthesis The Sled has been a success story with LINK since 1969. Unicondylar knee prostheses can be implanted with low bone destruction and a well-preserved ligamentus apparatus in the knee joint. Continually being improved on, the unicondylar sled delivers outstanding results in everyday clinical practice. In conjunction with the minimally invasive surgical technique MITUS® this surface replacement is particularly bone-sparing and gentle on soft tissue. In the Annual Report 2007* of the Swedish study (The Swedish Knee Arthroplasty Register – Part II) the Endo-Model® sled prosthesis features a survival rate of over 90% in 10 years with 4,124 implantations.
