在这两部分的论文的第一部分，在膝关节胫骨表面静压分布的测量结果。18例标本获得完整半月板的结果。其中8个标本在内侧半月板切除术后进行了进一步的测量。该研究是在膝关节的各种弯曲角度下进行的，关节受到压缩力，有或没有关节成员之间的初始被动相对位移。结果表明，关节压缩负荷的很大一部分是通过半月板传递的，全半月板切除术导致胫骨表面压力分布的剧烈改变。这些结果的临床意义，在半月板切除术后退行性改变和半月板病变的机制方面，已经讨论。
In this first part of a two-part paper, the results of measurement of static pressure distribution on the tibial surface of the knee are presented. Results with intact menisci have been obtained from 18 specimens. Eight of these specimens were the subject of further measurements following medial meniscectomy. The study has been carried out at various flexion angles of the knee with the joint subjected to a compressive force, with or without an initial passive relative displacement between the joint members. The results indicate that a significant fraction of the joint compressive load is transmitted through the menisci and that total meniscectomy causes a drastic alteration in the pressure distribution on the tibial surface. Clinical implications of these results, in terms of post-meniscectomy degenerative changes and mechanism of meniscal lesions, have been discussed.
