Tendon disorders are medical conditions that cause the tendons to malfunction.
These disorders affect two types of tendons: those without a synovial sheath and those with a synovial sheath. Tendonitis is termed for tendons that have no synovial sheath and tenosynovitis for those who have one.
The presence of pain in the afflicted area is a clinical sign of tendon disorder.A medical examination then reveals specific physical signs, including pain in the affected area, and sometimes swelling, redness and reduced mobility.
