This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
After tearing your anterior cruciate ligament (ACL) in your knee, surgery is often needed, but many people develop arthritis years later. This study is testing whether adding vibration therapy to your regular physical therapy after surgery can help prevent that arthritis and speed up muscle recovery. Researchers want to see if vibration therapy — either using a whole-body vibration platform or a focused muscle vibration device — works better than standard rehabilitation alone.
Many people who have ACL surgery end up with arthritis in that knee within a few years, which can end military careers and limit activities. Weak thigh muscles after surgery contribute to this problem. Early research shows vibration can improve muscle function quickly, but doctors don't yet know if it prevents arthritis or helps people return to sports safely.

You will visit a physical therapy clinic for 20 weeks of supervised rehabilitation. For the first month, you'll do standard post-surgery exercises. Then, depending on which group you're assigned to, you'll either continue with standard therapy alone, or add vibration therapy (either whole-body vibration or localized muscle vibration) before your regular exercises. You'll also have MRI scans of your knee and testing of your strength, walking, and jumping at different points during the study to see how well the treatment is working.
