Tendinopathy – Definition
Tendons connect muscle to bone and help move joints. Tendinopathy is an injury to the tendon. These injuries tend to occur in tendons near joints such as knee, shoulder, and ankle. The injuries can include:
- Tendinitis — an inflammation of the tendon. (Although this term is used often, most cases of tendinopathy are not associated with significant inflammation.)
- Tendinosis — microtears (tiny breaks) in the tendon tissue with no significant inflammation.
Tendinopathy and the associated pain may take months to resolve.
The following tendons are often involved:
- Achilles — back of heel
- Rotator cuff in the shoulder
- Biceps in the shoulder
- Wrist extensors near the elbow (on the outside)
- Wrist flexors near the elbow (on the inside)
- Patellar tendon (attached to the kneecap)
Sprain – Definition
A sprain is an injury that damages a ligament. A ligament is a firm, fibrous band of tissue. It connects two bones across a joint. There are ligaments crossing all of the joints in the body. Grade 1 and 2 sprains damage only the internal structure of a ligament. The ligament remains intact. Grade 1 is less severe than grade 2. Grade 3 sprains result in complete tears of the involved ligament. Grade 3 sprains are sometimes called torn or ruptured ligaments.
