Diagnosis and Management of Joint Pain Due to Excessive Use

Correct Diagnostic Terminology

The American Academy of Family Physicians recommends using the term "tendinopathy" instead of "tendonitis" for chronic overuse injuries, as the suffix "-itis" implies acute inflammation, but most patients have chronic symptoms indicating degenerative tendon changes rather than active inflammation 1, 2
The American Academy of Family Physicians suggests using the term "tendinosus" to specifically indicate degenerative changes in tendons 1, 2
The term "overuse tendinopathy" can be used when repetitive activity is the clear etiology of the injury 1

Patients with overuse tendinopathies typically present with insidious onset of load-related localized pain coinciding with increased activity, pain during activity that may subside after warm-up in early stages, and gradually increasing pain intensity and duration over time 1, 2, 3
Physical examination findings for overuse tendinopathies include well-localized tenderness on palpation, pain reproduced by maneuvers that simulate tendon loading, possible muscle atrophy with chronic conditions, swelling and asymmetry, and limited range of motion on the symptomatic side 1, 3

The most frequently affected sites for overuse tendinopathies are the rotator cuff, medial and lateral elbow epicondyles, patellar tendon, and Achilles tendon 1, 2

Overuse injuries result from repetitive microtrauma, causing collagen degeneration, hypovascular tendon degeneration, and disruption of the tendon structure 1, 2, 3

For pediatric patients with chronic mechanical back pain from overuse or repetitive sports activity, consider stress injuries including spondylolysis, particularly in sports involving compressive or rotational forces 4, 5
For hand joint pain from excessive use in adults over 40, consider hand osteoarthritis as an alternative diagnosis, particularly if there is pain on usage affecting DIP, PIP, or thumb base joints 6

Approximately 80% of patients with overuse tendinopathies fully recover within 3-6 months with conservative management, supporting the appropriateness of this diagnosis for most cases of joint pain from excessive use 1, 2

Lateral epicondylosis ("tennis elbow") is 7-10 times more common than medial epicondylosis and affects the dominant arm 75% of the time, typically occurring after age 40, according to the American Academy of Family Physicians 7
The American Academy of Physical Medicine and Rehabilitation recommends a conservative management sequence, including an initial phase with relative rest and NSAIDs for short-term pain relief, followed by a rehabilitation phase with eccentric strengthening exercises, for arm overuse tendinopathy 8
Deep transverse friction massage may reduce pain in patients with arm overuse tendinopathy, as suggested by the American Academy of Family Physicians 7
Avoid corticosteroid injections directly into tendons, as they can inhibit healing and reduce tendon strength, according to the American Academy of Family Physicians 7

Continue strengthening exercises for rotator cuff, scapular stabilizers, and core musculature even after symptoms resolve to prevent recurrence, as recommended by the American Academy of Physical Medicine and Rehabilitation 8
Maintain proper technique during repetitive activities to prevent recurrence, according to the American Academy of Family Physicians 7
