Treatment of Hamstring Tendinitis

Initial Conservative Management

The American Academy of Family Physicians recommends beginning with relative rest, ice therapy, and eccentric strengthening exercises as the foundation of treatment, with NSAIDs for acute pain relief, reserving surgery only for patients who fail 3-6 months of conservative management 1, 2
Reduce activity to decrease repetitive loading of the damaged hamstring tendon while avoiding complete immobilization, which leads to muscle atrophy and deconditioning 1, 2
Pain should guide activity levels—continue activities that don't aggravate symptoms while avoiding those that worsen pain 2
Topical or oral NSAIDs are effective for acute pain relief, though they cannot be recommended over other analgesics and do not affect long-term outcomes 1, 2
Topical NSAIDs provide equivalent pain relief with fewer systemic side effects compared to oral formulations 2
Ice therapy applied through a wet towel for 10-minute periods provides effective short-term pain relief by reducing tissue metabolism 2
Eccentric strengthening exercises are the cornerstone of rehabilitation and should be initiated once acute pain subsides 1, 2

Approximately 80% of patients with overuse tendinopathies fully recover within 3-6 months with appropriate conservative management 2
The condition typically presents with insidious onset of load-related localized pain coinciding with increased activity 1
Pain may initially subside after warm-up but gradually increases in intensity and duration, potentially becoming present at rest in later stages 1

Use corticosteroids with extreme caution—while they provide short-term pain relief, they do not improve long-term outcomes and may have deleterious effects on tendon healing 1, 2
Never inject directly into the tendon substance, as this inhibits healing, reduces tensile strength, and may predispose to rupture 1
Extracorporeal shock wave therapy (ESWT) appears safe and effective for chronic hamstring tendinopathy but is expensive 1, 2
Therapeutic ultrasonography, corticosteroid iontophoresis, and phonophoresis are of uncertain benefit 1

Surgery should be reserved for carefully selected patients who have failed 3-6 months of conservative therapy 1, 2

Do not completely immobilize the hamstring for extended periods—this causes rapid muscle atrophy, loss of strength and extensibility 1, 2
Avoid multiple corticosteroid injections, as they may weaken tendon structure despite providing short-term symptom relief 1
Do not proceed to surgery without an adequate 3-6 month trial of well-managed conservative treatment 1, 2
If multiple tendons are symptomatic, evaluate for underlying rheumatic disease before attributing symptoms solely to overuse 1

Most patients presenting to primary care have chronic symptoms suggesting degenerative tendinopathy ("tendinosus") rather than acute inflammation, despite the common misnomer "tendinitis" 2
Plain radiography is usually unable to demonstrate soft-tissue changes but may reveal bony abnormalities 1
