The inclusion criteria were as follows: (1) DMTs identified on preoperative MRI scans, (2) no definite history of trauma, and (3) follow\u2010up duration more than 5 years. In evaluation of the joint survivorship, the endpoint was defined as conversion to arthroplasty (or realignment osteotomy) or progression to Kellgren\u2013Lawrence grade 4. The study population was divided into older and younger groups by a cutoff age at which the difference in the joint survival rates was maximized, using a time\u2010dependent receiver operating characteristic (ROC) curve. The two groups were then matched based on propensity scores. The joint survival rates were compared between the groups using Kaplan\u2013Meier analysis, before and after propensity score matching (PSM).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 633\u00a0knees were included. The cutoff age was calculated as 60 years. Before PSM, 239\u00a0knees were allocated to the older group (\u2265\u200960 years) and 394\u00a0knees to the younger group (&lt;\u200960 years). A significant difference in the joint survival rates was noted between the groups (log\u2010rank test,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001). After PSM, 183\u00a0knees remained in each group. The difference in the survival rates was no more statistically significant (n.s.). The latest Lysholm scores of the older and the younger groups before PSM were 72.2\u2009\u00b1\u200920.8 and 79.9\u2009\u00b1\u200919.6, respectively (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001); however, the scores after PSM were 73.2\u2009\u00b1\u200920.3 and 77.4\u2009\u00b1\u200920.5, respectively (n.s.).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Joint survivorship after APM was affected by other factors associated with the aging process, such as cartilage status and meniscal tear pattern, rather than age itself. Advanced age should not be the only reason for precluding APM in treatment of DMTs. APM is a viable option when treating DMTs in elderly patients if adopted with caution. According to this study, a surgeon should assess the age\u2010related factors when he considers APM in elderly patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
