Tendonitis is inflammation and irritation to the tendon, the end of the muscle that attaches to the bone. Joints that are used with excessive repetitive movement are particularly susceptible to tendonitis. Treatment for tendonitis depends on the joint affected and the extent of the injury. Topical anti-inflammatory agents or oral medications may be ordered, along with physical therapy. Surgery may be required if the tendon ruptures.
Wrist Tendonitis
Wrist tendonitis or tenosynovitis, presents as pain, irritation and inflammation of the wrist joint tendons. The wrist has several tendons and one or more may be affected. Repetitive use such as typing on a computer, factory work and catching or throwing a ball, have been associated with wrist tendonitis. The tendons lose elasticity with age, and this makes the elderly more susceptible to tendon damage.
Patellar Tendonitis
Patellar tendonitis also known as jumper's knee, is most common in people who are involved with athletics. Those most at risk include soccer, volleyball and basketball athletes. The patellar tendon connects the kneecap to the shinbone and is active in all movements of the legs---jumping, bicycling and kicking. Knee pain accompanied with swelling and redness around the knee indicate a need to contact your doctor.
Achilles Tendonitis
According to the Sports Injury Clinic, Achilles tendonitis accounts for about 11 percent of all running injuries. With the Achilles tendon being the largest at the back of the ankle, it supplies the power from the heel bone to the large calf muscles to start the walking or running cycle. Achilles tendonitis can occur as an acute or chronic condition. Causes of Achilles tendonitis include weak calf muscles, increase in walking or running activity, wearing high heels, extensive running uphill and a change of footwear.
Rotator Cuff Tendonitis
Rotator cuff tendonitis may be caused by overuse, impingement or calcium deposits. Overuse can be from throwing, painting or swimming. Impingement may be the result of a fall or weak shoulder muscles. Irritation from calcium deposits in the tendons can cause rotator cuff tendonitis. Surgery may be required if oral medications or a shot in the shoulder joint do not resolve the pain.
Elbow Tendonitis
Elbow tendonitis better known as tennis elbow, is the result of repetitive motions stressing the tissue in and around the elbow. Playing tennis is one cause, but activities, such as factory workers and body builders, are just as likely to cause elbow tendonitis. According to Mayo Clinic, those most susceptible to elbow tendonitis are adults between 30 and 50 years of age, and those who smoke. Repetitive elbow movement for a minimum of two hours a day add to the risk, says the Mayo Clinic.
