我42岁，以前从没有参加过锻炼，经常腰酸背痛。打从两年半前开始，我每周五天有规律地到健身中心做健身锻炼，每次1小时（起初是跑步机，后来只跟着Instructor做Step和cardiopump）。自从锻炼以后，身体感觉很轻松，因而很乐意坚持下去。但是，一年前发现有时膝关节有点儿疼痛，倒不至于影响生活。X射线检查未发现异常。大概今年3月份开始，感觉膝部又有些不适，所以最近又去做了次X射线检查，结果如下。请专家们给看看，到底问题有多严重，是否需要停止锻炼，应该注意什么。不胜感激！

Right knee, skyline, tunnel & WB views:
Mild degenerative changes of the patellofemoral compartment with minimal lateral subluxation of the patella with respect to the femoral groove. No knee joint effusion. The medial and lateral compartments are relatively well preserved with no significant degenerative changes. No radiopaque intra-articular loose bodies.
Single frontal view of the left knee is unremarkable.
