height similarly the superior surface 304 of the implant 300 can be designed to match the shape of the femoral condyle including cartilage or bone or both the inferior surface 302 of the implant 300 can be a composite of the surface of the tibial plateau in particular in areas that are not covered by menisci and the meniscus thus at least a portion of the outer aspects of the device can be a reflection of meniscal height accounting for compression this can be for example 20 40 60 or 80 of uncompressed meniscal height these same properties can be applied to the implants shown in fig4 8 as well in some embodiments the outer aspect of the device reflecting the meniscal shape can be made of another preferably compressible material if a compressible material is selected it is preferably designed to substantially match the compressibility and biomechanical behavior of the meniscus the height and shape of the menisci for any joint surface to be repaired can be measured directly on an imaging test if portions or all of the meniscus are torn the meniscal height and shape can be derived from measurements of a contralateral joint or using measurements of other articular structures that can provide an estimate on meniscal dimensions in another embodiment the superior face of the implants 300 400 or 500 can be shaped according.
