Stage (VISA-A Score)	Score Range	Symptoms	Load Tolerance	Treatment Focus
Reactive (acute)	VISA-A 50-70	Acute-onset pain; tendon stiff and sore; recent load spike	Reduced; pain with loading	Relative rest; reduce provocative load; isometric exercises; ice
Tendon Dysrepair	VISA-A 30-60	Failed to fully resolve; persistent stiffness; pain with activity	Moderate reduction	Progressive loading; HSR protocol; manage training load
Degenerative	VISA-A less than 30	Chronic; often painless nodule in tendon; poor response to loading	Severely reduced; intratendinous pathology on MRI	HSR + ESWT + PRP; surgery for non-responders at 6 months
Full Thickness Tear / Rupture	N/A (acute)	Pop; inability to push off; positive Thompson test	None	Surgical repair (active) or functional bracing (sedentary); 6-12 months recovery

Quick answer: Treatment for achilles tendinopathy midportion pain treatment michigan follows a stepwise approach: 1) conservative care first (rest, ice, supportive footwear, OTC anti-inflammatories), 2) physical therapy and targeted exercises, 3) in-office treatments (injections, custom orthotics) if conservative fails at 4-6 weeks, 4) surgery for refractory cases. Most patients resolve at step 1 or 2. Call (810) 206-1402.

Understanding Achilles Tendinopathy

Achilles tendinopathy is a chronic degenerative condition of the Achilles tendon — the largest and strongest tendon in the body — characterized by pain, swelling, and functional impairment. While many patients and even some providers refer to this as “Achilles tendinitis,” research over the past two decades has established that the chronic, long-standing form is driven by tendon degeneration (tendinosis) with minimal acute inflammation rather than classic tendinitis.

Midportion Achilles tendinopathy — the most common variant — produces symptoms in the zone 2–6 cm above the calcaneal insertion, where the tendon is most vulnerable to mechanical loading. At Balance Foot & Ankle PLLC, Dr. Tom Biernacki distinguishes midportion tendinopathy from insertional Achilles tendinopathy (at the heel bone itself) because the two require fundamentally different treatment approaches.

Causes and Risk Factors

Midportion Achilles tendinopathy develops from a mismatch between tendon loading demands and the tissue’s capacity to adapt. Contributing factors include:

Rapid training load increases: The most common trigger in runners and athletes — increasing mileage, intensity, or training surface too quickly. The Achilles tendon adapts slowly to load; exceeding its adaptation capacity triggers degenerative changes.

Biomechanical factors: Overpronation increases medial Achilles tendon stress through a “wringing” mechanism as the tendon twists during pronation. High arches increase loading on the lateral tendon fibers.

Age and stiffness: Tendon tissue becomes stiffer and less vascular with age, increasing degenerative susceptibility. Men aged 35–55 are disproportionately affected.

Fluoroquinolone antibiotics: A well-documented risk factor — these antibiotics directly impair tendon collagen synthesis and dramatically increase tendinopathy and rupture risk.

Symptoms and Diagnosis

Classic symptoms include a “painful arc” — maximum tenderness at a specific point 2–6 cm above the heel that moves with the tendon when the ankle is ranged. Morning stiffness and pain that improves after a few minutes of walking (“warm up” phenomenon) is hallmark. A palpable or visible nodular thickening (a tendon fusiform swelling) at the tendinopathic zone is common.

Dr. Biernacki diagnoses Achilles tendinopathy clinically and confirms severity with diagnostic ultrasound, which shows tendon thickening, hypoechoic areas of degeneration, and neovascularization. MRI is reserved for complex cases or when partial rupture is suspected.

Treatment: The Evidence-Based Approach

Eccentric loading — the Alfredson protocol: The most evidence-based intervention for midportion Achilles tendinopathy. Eccentric calf drops performed on a step — 3 sets of 15, twice daily, for 12 weeks — consistently produce significant pain reduction and tendon remodeling in multiple high-quality trials. This is uncomfortable initially (it should be done into mild pain), but compliance is key to outcomes. Most patients with midportion tendinopathy should begin here.

Load management: Reducing but not eliminating tendon loading during the initial rehabilitation phase. Complete rest worsens tendinopathy — the tendon requires appropriate stimulation to remodel. Cross-training (cycling, swimming) maintains fitness while reducing high-impact Achilles stress.

Custom orthotics: A heel lift (3–6 mm) reduces Achilles tendon strain by decreasing the required ankle dorsiflexion during gait. For pronating patients, a custom orthotic that corrects subtalar pronation also reduces the “wringing” stress on the medial tendon fibers.

Ultrasound-guided PRP injections: Platelet-rich plasma (PRP) injections deliver concentrated growth factors directly into the tendinopathic zone under ultrasound guidance. PRP is supported by growing evidence for chronic midportion tendinopathy that has failed eccentric loading programs. Importantly, corticosteroid injections are contraindicated in midportion Achilles tendinopathy due to the risk of tendon rupture.

Extracorporeal shockwave therapy (ESWT): High-energy sound waves applied to the tendinopathic zone stimulate healing and reduce pain. Multiple trials support ESWT for chronic tendinopathy that has failed conservative care.

Surgical Treatment

When 3–6 months of structured conservative management fails, surgical debridement of the degenerative tendon core (tendon stripping, longitudinal tenotomy, or open/arthroscopic debridement) is considered. Neovascular vessels that contribute to pain are also addressed. Recovery involves 6–12 weeks of progressive rehabilitation. Good outcomes are achieved in approximately 80% of appropriately selected surgical cases.
