Tendon Injuries (Foot & Ankle)
Achilles, peroneals, posterior tibial — the cables that power every step.
Overview
Understanding tendon injuries (foot & ankle)
The foot and ankle run on tendons: the Achilles drives push-off, the peroneals stabilize the outer ankle, and the posterior tibial tendon holds up your arch. Injuries range from overload tendinopathy — painful, thickened tendon from training spikes — to complete ruptures.
Tendon problems respond to fundamentally different care than muscle strains: they need progressive loading, not rest, and the window for straightforward repair after rupture rewards prompt diagnosis.
Symptoms
What it feels like
- Achilles: morning stiffness and pain above the heel; a "kicked in the leg" pop signals rupture
- Peroneals: outer ankle pain, snapping, or instability
- Posterior tibial: inner ankle ache and a flattening arch
- Swelling or thickening along the tendon
Common causes
Why it happens
- Training volume spikes and return-to-sport surges
- Age-related tendon changes — rupture peaks in the 30s–40s "weekend athlete" years
- Untreated ankle instability overworking the peroneals
- Certain antibiotics and medical conditions that weaken tendon
Diagnosis
How it's diagnosed
Exam makes most tendon diagnoses — including the Thompson squeeze test for Achilles rupture. Ultrasound and MRI grade degeneration, confirm tears, and map retraction when surgery is being planned.
Treatment
The full range of options
Non-surgical
Progressive loading programs
Eccentric and heavy-slow-resistance protocols are the evidence-based core of tendinopathy care — rebuilding the tendon's capacity over 8–12 weeks.
Functional rupture management
Selected Achilles ruptures do well non-surgically with early functional bracing protocols — a genuine option Dr. Johnson will discuss honestly alongside repair.
Orthotics & footwear strategy
Arch support offloads the posterior tibial tendon; heel lifts calm an irritated Achilles during rehabilitation.
Surgical
Achilles repair
Reapproximating the ruptured tendon — including minimally invasive techniques — favored for athletes and patients prioritizing push-off strength.
Tendon debridement & transfer
Chronic degenerated segments are cleaned or reinforced with a transferred tendon; advanced posterior tibial dysfunction may pair tendon work with realignment.
Recovery
The road back
Tendinopathy programs deliver over two to three months of committed loading. Achilles rupture recovery — surgical or functional — runs through a boot-and-wedges progression toward strengthening, with return to sport commonly in the six-to-nine-month range and calf strength as the gatekeeper.
Dr. Johnson's approach
Dr. Johnson treats tendons with the respect biology demands: loading programs done properly before procedures, honest presentation of surgical versus functional care for ruptures, and repair techniques chosen for your push-off demands.
