Often we rush to surgery when something is torn or worn. We have learned, in recent years, that these small ‘wear and tears’ around the body are normal and do not at all correlate to pain. Think of them like wrinkles on your skin, a sign of ageing, but not painful.
Some examples of things that don’t need surgery as often as you think are rotator cuff tears of the shoulder, hamstring avulsions, ACL tears.
For example the ACL isn’t really required if you only wish to stay strong and healthy and move in straight lines or run. You only really need your ACL if you are playing fast, multi-directional sports.
