U might want to consider Tai Chi. I started Tai Chi at the recommendation of my primary care physician and a physical therapist I knew after I had a crash on my '95 Cota, damaged both knees and almost lost a finger! :-0
It worked superbly and is used by more knowledgeable Physical Therapists as one part of some patients treatment. Depending on your situation, reputable Tai Chi programs will be able to refer you to other students, rehab programs, and licensed health care practitioners in your area. The Tai Chi Center might already offer various kinds of rehabilitation programs in your community. At my first class, the instructor's had experience with similar injuries like mine, and worked with some of my Physician's patients. Some students were doing a seated style matched to their health condition. The Center offered programs at a hospital, sports rehab centers, community centers, retirement communities, nursing homes, etc.
I use it for cross-training in trials, sea/whitewater kayaking, mountain biking, Traditional Chinese archery, and has even helped me for more dangerous physical home repairs. It really helped my balance, form, response time, overall confidence, and I just feel better. Most of us know it's a wonderful life-long method of health prevention and stress reduction.
The International Taoist Tai Chi Society offers programs in many parts of the world. My teachers in the US were credentialed (including health-related training), professional, and had an initial consult with me to better understand my needs. The society is non-profit, monthly fees are low and adjustable depending on what you can afford, respected, historically correct style, and have been around for decades. They are not a fly-by-night for-profit marital arts studio, with inept instructors, fake styles, high fees, and close in a few months or year (in our city they come and go like the snakes around my home)!
