Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Exercise prescription and weight management
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Achilles Tendon Stretching and Strengthening Program
A structured physical therapy program focusing on eccentric strengthening exercises for the gastrocnemius-soleus complex and progressive stretching to improve tendon flexibility and load tolerance. Treatment typically involves supervised sessions combined with home exercise compliance.
Activity Modification and Footwear Optimization
Reduction of high-impact activities that stress the Achilles tendon, combined with selection of appropriate footwear with proper heel support and cushioning. Gradual return to activity protocols should be implemented.
Additional treatment options
NSAIDs for Pain Management
Non-steroidal anti-inflammatory medications may be used short-term to manage pain and inflammation associated with abnormal Achilles tendon morphology. Treatment should be combined with rehabilitative measures.
medicationTendon Debridement or Repair Surgery
Surgical intervention may be considered for severe cases or when conservative management fails. Procedures range from tendon debridement to augmentation or repair depending on the specific pathology identified.
surgicalExtracorporeal Shock Wave Therapy
ESWT uses acoustic waves to stimulate healing in chronic Achilles tendinopathy by promoting blood flow and cellular regeneration. Typically reserved for cases resistant to conventional therapy.
