Sports medicine injection
Is hyaluronic acid injection suitable for sports injury or knee osteoarthritis?
Doctor’s answer
Hyaluronic acid is mainly used for selected patients with knee osteoarthritis or degenerative joint pain, aiming to improve lubrication and short-term symptoms. It should not replace strength training, weight management, and load modification. Acute ligament, meniscus, or infection-related problems need a clear diagnosis first.

Are corticosteroid injections for joint or tendon pain safe, and can they be repeated?
A local corticosteroid injection may provide short-term pain relief for selected cases of arthritis, bursitis, or tenosynovitis. Safety depends on the injection site, dose, and interval. Repeated injections or injections close to a tendon may increase tissue weakening and rupture risk, so the diagnosis should be clear before treatment.
Does PRP injection work for sports injuries, and who may benefit?
The effects of platelet-rich plasma (PRP) vary with the condition, duration of symptoms, and preparation method. Selected patients with chronic tendinopathy or mild-to-moderate joint degeneration may discuss PRP when structured rehabilitation has provided limited relief. Review the strength of evidence, cost, and realistic expectations before treatment.
Why should rehabilitation after sports medicine surgery not follow time alone?
A timeline gives only a rough stage. Progress is determined by pain, swelling, range of motion, strength, movement control, tissue healing, and what was done during surgery. Moving too quickly may increase failure risk; moving too slowly may lead to stiffness and loss of function.
