http://0rz.tw/d033B 乡民真是卧虎藏龙 有人从美国运动医学期刊 (American Journal of Sports Medicine) 上面转贴了一篇关於 microfracture 手术的论文 原文很长而且很学术 有兴趣可以点进去看 简介：此篇论文发表於 5/23/2006，主题是追踪 32 名动过 microfracture 手术的运动 员，年龄分布是 16 至 54 岁，都在动完手术追踪了至少两年。 以下来贴另一个乡民做的摘要 以及我的翻译： 1-Lesion location did not affect outcome, as good and excellent outcomes were similar for lesions located on the medial femoral condyle (65%), lateral femoral condyle (71%), and trochlea (62%). 伤口的位置不影响复原的结果，伤口在三种不同位置（专业名词就略过吧@@）复原的机率 都差不多。 2 The preoperative duration of symptoms was found to be an important factor for cartilage repair with microfracture in our study. Our data indicate that the longer the interval between injury and microfracture, the lower the rate of return to high-impact athletics. In our study, the successful return rate increased from 44% to 67% if microfracture was performed within 1 year after articular cartilage injury. 症状开始出现到动手术这段时间的长短很重要。拖得越久，手术後重新回到场上的机率 就越低。研究显示如果在症状出现一年内就动手术的话，成功复出的比率就从 44% 提昇 到 67%。 Oden: 症状出现一个月就动了手术。 3 Athletes returning to high-impact sports after microfracture were younger than were athletes who failed to return to their demanding sport. Younger age has been previously associated with better functional outcome after microfracture. 越年轻动刀，成功复出的比率就越高。 Oden: 19岁 4 Athletes with no prior surgical intervention had a better rate of return to high-impact athletics than did those who had undergone knee surgery before microfracture. 动 microfracture 的膝盖之前如果没有动过别的手术，复出的机率就越高。 Oden:第一次动膝盖手术。 5 The mean lesion size in athletes who failed to return was larger than that of patients who were able to return, but this difference was not statistically significant (P = .176) (Table 2). However, we found that athletes with lesion size 200 mm2 had a significantly higher return rate (64%) to high-impact sports than did athletes with lesions >200 mm2 (22%, P = .04). 伤口面积越小，复出的比率越高。200 平方公厘是个门槛，如果伤口小於这个大小则成功 复出的比率会高很多（64% vs. 22%） Oden: 据 Pritchard 说他的伤口很小，大概只有指甲大小，虽然没有精确的数字，不过 估计大约是一公分见方，也就是 100 平方公厘吧 这五项要素 Oden 统统都具备。但是下面这段话又有点不太乐观： Although significant increases in functional outcome scores were observed in patients returning to high-impact athletics, functional increases were lower in patients who failed to return to the sport (Figures 1 and 2). After an initial increase, a decline of the activity scores was observed in 15 athletes (47%). Age, duration of symptoms, or lesion size or type did not affect the incidence of decreasing functional scores. 成功复出的运动员在各项膝盖功能测试的结果，跟手术前相比都有显着的进步，未能成功 复出的运动员进步的幅度则没有那麽大。（这应该是当然的吧，重点在下句话）有 47% 的运动员虽然手术後一开始有进步，但是之後膝盖功能又退步了，这个现象跟年龄、拖了 多久才动手术或是伤口大小都没有关系。 --
