Why would your doctor give you a shot of celestone/lidocaine as a diagnose to determine if you need a knee replacement ?

Knee replacement: The doctor may have wanted to give you some pain relief. However, usually the decision is made by xrays, physical exam and symptoms.

Knee injection: The knee can be caused by arthritis, ligament injury, tendon tears, muscle strain ... The steroid injection is primarily used for knee pain. It's not commonly used to determine if you need a knee replacement. Please see a pain management doctor or orthopedic surgeon for a comprehensive evaluation and treatment.

Pain relief response: The amount of pain relief in response to a therapeutic cortisone injection can help predict the pain relief with surgery, i.e. Knee replacement. If no pain relief at all, then unlikely that surgery would be beneficial in resolving the pain. If good resolution of pain, but only temporary, then good prognostic sign that surgery will provide longer lasting pain relief.
