What is Knee pain?
Knee pain is a common complaint that affects people of all ages. This pain maybe secondary to the knee joint itself secondary to arthritic changes that occur over time or can be related due to an injury to the structures that form the knee such as the meniscus or ligaments. Less commonly, people can also experience knee pain that is referred from the lower back due to a pinched nerve or secondary to poor blood flow.
With knee arthritis that happens over time and is more common in people that are obese and those that exhibit an active life style. In this group of people bone spurs within the knee joint that can limit joint mobility and contribute to pain.
Some people may continue to experience knee pain despite having a knee replacement and this is usually secondary to the irritation of nerve around the knee that cause the patient to have pain.
Thus, proper workup with history and physical exam is necessary to identify the exact cause of your pain to formulate the proper treatment plan. Workup may require diagnostic nerve blocks, imaging and/or electrodiagnostic studies (Nerve conduction studies and Electromyography).
