Yes keeping strong and being active in sports are great ideas, and is obviously something you enjoy. so keep going. As our joints and soft tissues get a a bit older, compensating by building muscle strength is a great way to keep on the field, have less pain and injuries and counter the aging in our locomotor system. And you re right with joint hyper mobility - building and keeping muscle strength can keep this in check.

Even if you do have a Wikipedia reference-linkmeniscus problem that eventually requires a visit to the surgeon, keeping your knee as strong as possible may reduce the need for that intervention and if not, improve the post-surgical outcome and reduce rehab time.
