Alternative methods for repairing knees without knee replacement surgery include physical therapy and knee injections, according to Healthline. Other methods are stem cell injections or weight loss and exercise.
Physical therapists have the ability to design programs based on individual needs for knee reparation, explains Healthline. They help patients learn the correct way to exercise and sometimes professionally apply ice and heat or use transcutaneous electrical nerve stimulation, or TENS, treatments. Hyaluronic acid injections into the knee help lubricate the joint and act as shock absorbers. The injections allow the cartilage and bone tissues to glide more smoothly, which improves mobility.
