It is widely accepted that total\/partial loss of the meniscus increases the risk of joint degeneration. A short-term method for evaluating whether degenerative arthritis can be prevented or not would be to determine if the peak pressure and contact area coverage of the tibial plateau (TP) in the knee are restored at the time of implantation. Although several published studies already utilized TP contact pressure measurements as an indicator for biomechanical performance of allograft menisci, there is a paucity of a quantitative method for evaluation of these parameters in situ with a single effective parameter. In the present study, we developed such a method and used it to assess the load distribution ability of various meniscal implant configurations in human cadaveric knees (n=3). Contact pressures under the intact meniscus were measured under compression (1200 N, 0 deg flexion). Next, total meniscectomy was performed and the protocol was repeated with meniscal implants. Resultant pressure maps were evaluated for the peak pressure value, total contact area, and its distribution pattern, all with respect to the natural meniscus output. Two other measures\u2014implant-dislocation and implant-impingement on the ligaments\u2014were also considered. If any of these occurred, the score was zeroed. The total implant score was based on an adjusted calculation of the aforementioned measures, where the natural meniscus score was always 100. Laboratory experiments demonstrated a good correlation between qualitative and quantitative evaluations of the same pressure map outputs, especially in cases where there were contradicting indications between different parameters. Overall, the proposed approach provides a novel, validated method for quantitative assessment of the biomechanical performance of meniscal implants, which can be used in various applications ranging from bench testing of design (geometry and material of an implant) to correct implant sizing.<\/jats:p>","DOI":"10.1115\/1.4000407","type":"journal-article","created":{"date-parts":[[2009,10,5]],"date-time":"2009-10-05T22:00:19Z","timestamp":1254780019000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":34,"title":["A Novel Quantitative Approach for Evaluating Contact Mechanics of Meniscal Replacements"],"prefix":"10.1115","volume":"132","author":[{"given":"E.","family":"Linder-Ganz","sequence":"first","affiliation":[{"name":"Research and Development Center, Active Implants Corporation, Netanya, 42505 Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
