本研究的目的是分析身体膝关节标本中交叉韧带、胫骨平台关节软骨和半月板的形态解剖和随年龄增长的损伤。使用Image-Pro(R)软件对3个年龄组(=80岁)的膝关节身体解剖进行了形态计量分析。用尼龙线测量每个标本5周的平均十字韧带厚度。用表面积测量评估胫骨平台关节软骨退行性变的百分比和半月板的覆盖率。80岁组的胫骨内侧平台关节软骨的表面积退行性变(mm(2))是70-79岁组的1.7倍(P<；0.05)。随着年龄的增长，内侧半月板也经历了退行性变化，表现为胫骨平台覆盖率的减少。随着年龄的增长，前十字韧带(ACL)经历了显著的退行性变薄。70至79岁的标本的平均前交叉韧带周长(Mm)比80岁的标本减少了1.2倍(10.5%)，比80岁的标本减少了1.24倍(19%
The objective of this study was to analyze morphometric anatomy and damages with aging in cadaveric knee specimens specific to the cruciate ligaments, the articular cartilage of the tibial plateau, and the menisci. Morphometric analyses to cadaveric anatomy of the knee were performed using Image-Pro (R) software on 3 age populations: = 80 years old. An average thickness of the cruciate ligaments was assessed with 5 circumferential measurements per specimen using nylon thread. Percent degeneration of the tibial plateau's articular cartilage and coverage by menisci was assessed with surface area measurements. The articular cartilage of the medial tibial plateau in >= 80 years old specimens showed a 1.7-fold increase in surface area degeneration (mm(2)) compared to 70 to 79 years old specimens (P < 0.05). The medial meniscus also experienced degenerative changes with aging, which were expressed as decreases in tibial plateau coverage. The anterior cruciate ligament (ACL) experienced substantial degenerative thinning with aging. The 70 to 79 years old specimens had a 1.2-fold (10.5%) decrease in average ACL circumference (mm) compared to the = 80 years old specimens had a 1.24-fold (19%) decrease in ACL circumference compared to the
