Short answerThe Achilles paratenon is the superficial tissue surrounding the tendon. Direct, strong clinical data for laser in paratenon-derived pain and tenderness is limited. High-power laser studies in Achilles tendinopathy provide indirect support.
Symptoms
Superficial tenderness around the Achilles, a friction sensation, pain with exercise, and sometimes local swelling can be seen.
980 and 1470 nm
980 nm is the main adjunctive wavelength for the tendon and surrounding tissues. Because the paratenon is quite superficial, 1470 nm may be anatomically accessible; however, there is no direct efficacy data, and the thermal load must be carefully controlled.
Scientific evidence
Level of evidence: C+. There is a high-power laser RCT for Achilles tendinopathy; paratenon-specific evidence is limited.
Our approach in our Bodrum clinic
We differentiate paratenon pain from midportion tendinopathy, insertional pain, and partial tear; we add laser to load management and calf strengthening.
