No, you do not need an ACL to play golf.
However, a knee brace may be a good option for you if you have had an ACL injury in the past.
Many professional golfers use knee braces to help protect their knees while playing, and they can be especially helpful for athletes who have had an ACL injury.
If you are experiencing any pain or discomfort while playing golf, it is best to stop and consult with your doctor.
