Final answer:
Tendinosis is a chronic condition characterized by degeneration of tendon collagen without substantial inflammation, while tendinitis involves inflammation due to overuse of tendons. The term tendinosis is used when the collagen degeneration overshadows the inflammatory response.
Step-by-step explanation:
The term tendinosis is used instead of tendinitis to describe a tendon condition that lacks significant inflammation. Tendinitis refers to the inflammation of a tendon and is a result of microtraumas from overuse, leading to an inflammatory response.
On the other hand, tendinosis is a chronic condition that involves degeneration of the tendon's collagen in response to chronic overuse or aging, without substantial inflammation.
Persons whose jobs or hobbies entail repetitive movements are at higher risk for tendinosis and tendinitis. Some individuals might experience tendon injuries such as tennis elbow, jumper's knee, or swimmer's shoulder, primarily due to repetitive stress that damages the tendons over time.
While tendinitis can be treated with rest and physical therapy, tendinosis may require a longer healing period since collagen degeneration is more complex to reverse.
Preventive measures for these tendon disorders include proper technique, stretching before exercises, cross-training, strength exercises to increase tendon resilience, and ensuring adequate rest to prevent overuse.
