The Gastrocnemius Recession, also known as the Strayer Procedure, is a surgical technique designed to lengthen the tight gastrocnemius muscle in the calf. Tightness in this muscle, called gastrocnemius equinus contracture, can limit upward ankle movement (dorsiflexion) and lead to conditions such as plantar fasciitis, Achilles tendinitis, and flatfoot deformity. By releasing the tension in the gastrocnemius, this procedure helps restore normal motion, relieve pain, and improve overall foot function.
How Common It Is and Who Gets It? (Epidemiology)
Gastrocnemius recession is most commonly performed in adults who suffer from chronic heel or foot pain caused by calf tightness that has not responded to conservative care. It is also used in pediatric and neurologic patients with contractures or toe-walking. The condition is prevalent among runners, individuals with plantar fasciitis, and people with diabetes or other systemic disorders that affect muscle flexibility.
Why It Happens – Causes (Etiology and Pathophysiology)
The gastrocnemius muscle forms part of the calf and connects to the Achilles tendon, which attaches to the heel bone. When the muscle is too tight, it limits dorsiflexion (the ability to point the foot upward). This tightness forces compensatory stress on the Achilles tendon, plantar fascia, and midfoot joints, leading to pain, inflammation, and deformity. Common causes include:
- Long-standing plantar fasciitis or Achilles tendinopathy.
- Flatfoot or cavus foot deformities.
- Bunion or forefoot overload due to equinus contracture.
- Neurologic disorders or postural adaptation (toe-walking).
- Post-surgical or post-traumatic scarring of the calf muscles.
How the Body Part Normally Works? (Relevant Anatomy)
The gastrocnemius is one of two primary calf muscles (the other is the soleus). It crosses both the knee and ankle joints and is responsible for plantar flexion—pointing the foot downward—and knee flexion. When the gastrocnemius is too tight, ankle dorsiflexion is limited, especially when the knee is straight. The Strayer Procedure specifically targets the tendon of the gastrocnemius, located just below the knee crease, to relieve this restriction while preserving the function of the deeper soleus muscle.
What You Might Feel – Symptoms (Clinical Presentation)
Typical symptoms of gastrocnemius tightness include:
- Heel pain, especially when walking or standing.
- Tightness or cramping in the calf.
- Difficulty walking with the heel touching the ground.
- Pain along the Achilles tendon or arch of the foot.
- Limited upward ankle motion (positive Silfverskiöld test).
If untreated, this condition can contribute to chronic plantar fasciitis, flatfoot, and metatarsalgia.
How Doctors Find the Problem? (Diagnosis and Imaging)
Diagnosis is based on clinical examination and functional testing:
- Silfverskiöld Test: The patient’s ankle motion is measured with the knee bent and straight. A marked improvement in dorsiflexion when the knee is bent indicates isolated gastrocnemius tightness.
- Imaging (X-ray, MRI): Typically used to rule out other causes like bone spurs or Achilles tendon pathology.
- Gait analysis: May reveal early heel rise or toe-walking during stride.
Classification
Gastrocnemius contractures are classified by severity (mild, moderate, severe) based on the degree of restricted dorsiflexion and by type:
- Isolated gastrocnemius equinus: Tightness in the gastrocnemius only (most common).
- Combined gastrocnemius-soleus equinus: Both calf muscles are involved.
Other Problems That Can Feel Similar (Differential Diagnosis)
- Plantar fasciitis.
- Achilles tendinitis.
- Posterior ankle impingement.
- Tarsal tunnel syndrome.
- Midfoot arthritis.
Treatment Options
Non-Surgical Care
Initial management aims to stretch and lengthen the calf muscles:
- Physical Therapy: Stretching exercises, night splints, and massage therapy.
- Orthotics: Heel lifts or supportive insoles to reduce strain.
- Activity Modification: Avoiding high-impact activities.
- Casting or Bracing: Short-term immobilization for severe cases.
When these treatments fail after several months, surgery may be indicated.
Surgical Care
The Strayer Procedure (CPT 27687):
- Anesthesia: Usually performed under general or regional anesthesia.
- Positioning: The patient lies face down with the foot hanging off the table for optimal access.
- Incision and Exposure: A small posteromedial incision is made in the calf, just below the knee crease, where the gastrocnemius tendon joins the soleus.
- Tendon Release: The tendon of the gastrocnemius is identified and carefully cut to lengthen the muscle. The sural nerve—which runs close to the surgical site—is identified and protected.
- Stretching and Closure: The ankle is gently dorsiflexed to confirm improved range of motion. The incision is closed with sutures, and a dressing or boot is applied.
Research Insight on Surgical Anatomy:
A study of 40 Strayer procedures found that the sural nerve lies superficial to the fascia in 42.5% of cases and deep in 57.5%. In about 12.5% of cases, it was directly on the gastrocnemius tendon, requiring gentle dissection. The optimal release point was, on average, 18 mm distal to the lower edge of the gastrocnemius muscle belly. The authors recommended a posteromedial incision starting 2 cm distal to the gastrocnemius indentation to minimize incision size and reduce nerve injury risk.
Recovery and What to Expect After Treatment
- Immediate Postoperative Care: A soft cast or walking boot is applied. The leg is elevated, and weight-bearing is typically limited for 2–3 weeks.
- Physical Therapy: Begins within 2–4 weeks to maintain flexibility, prevent scarring, and restore normal gait.
- Full Recovery: Most patients resume normal walking by 6–8 weeks and return to sports or full activity by 3 months.
- Pain Relief: Significant reduction in heel and calf pain occurs within 2–3 months.
Possible Risks or Side Effects (Complications)
- Calf hematoma or bruising.
- Delayed wound healing.
- Sural nerve injury: May cause numbness or tingling in the lateral foot.
- Residual tightness or over-lengthening: Rare but possible.
Complication rates are low when the anatomy is respected and an experienced surgeon performs the operation.
Long-Term Outlook (Prognosis)
The Strayer procedure has a success rate exceeding 90%, with substantial improvement in ankle dorsiflexion and pain relief. Most patients regain full function and experience long-term resolution of plantar fasciitis or Achilles tendinopathy.
Out-of-Pocket Cost
Medicare
CPT Code 27687 – Gastrocnemius Recession (Lengthening of the Calf Muscle): $106.77
Medicare Part B typically covers 80% of the approved cost for this procedure once your annual deductible has been met, leaving you responsible for the remaining 20%. Supplemental Insurance plans such as Medigap, AARP, or Blue Cross Blue Shield generally cover that 20%, significantly reducing or eliminating out-of-pocket expenses for Medicare-approved procedures. These plans coordinate with Medicare to close the coverage gap and minimize patient costs.
If you have Secondary Insurance such as TRICARE, an Employer-Based Plan, or Veterans Health Administration coverage, it acts as a secondary payer. These plans often cover any remaining balance, including coinsurance or small deductibles, which usually range between $100 and $300, depending on your plan and provider network.
Workers’ Compensation
If your gastrocnemius recession is required due to a work-related injury or chronic strain, Workers’ Compensation will cover all associated medical costs, including surgery, rehabilitation, and follow-up visits. You will not have any out-of-pocket expenses, as the employer’s insurance carrier pays directly for all approved procedures.
No-Fault Insurance
If your gastrocnemius tightness or associated foot condition is related to an automobile accident, No-Fault Insurance will typically cover the entire cost of your treatment, including the procedure and postoperative care. The only potential out-of-pocket cost may be a small deductible or co-payment depending on your insurance policy.
Example
Michael Carter underwent a gastrocnemius recession (CPT 27687) to improve ankle flexibility and relieve chronic calf tightness. His estimated Medicare out-of-pocket cost was $106.77. Because Michael had supplemental insurance through AARP Medigap, his remaining balance was fully covered, leaving him with no out-of-pocket expenses for the surgery.

Summary and Takeaway
The Strayer Procedure (Gastrocnemius Recession) is a reliable, minimally invasive solution for chronic calf tightness causing foot and ankle pain. By lengthening the gastrocnemius tendon, it restores normal motion and relieves tension on the plantar fascia and Achilles tendon. The operation has an excellent safety profile, short recovery time, and high patient satisfaction when performed by an experienced surgeon.
Clinical Insight & Recent Findings
A recent study published in The Iowa Orthopedic Journal examined how a patient’s mental resilience affects recovery after isolated gastrocnemius recession—a surgery often done for plantar fasciitis or Achilles tendinopathy.
Researchers reviewed outcomes for 189 patients who had the Strayer procedure and found that those with higher resilience scores (measured by the Brief Resilience Scale) reported significantly better physical function, less pain, and lower depression levels on standard outcome scales (PROMIS and FFI).
The study concluded that resilience plays a measurable role in how well patients recover from gastrocnemius recession, suggesting that addressing psychological readiness and resilience before surgery may enhance results and satisfaction.

Who Performs This Treatment? (Specialists and Team Involved)
The procedure is performed by an orthopedic foot and ankle surgeon or a podiatric foot and ankle surgeon with expertise in lower limb biomechanics. The surgical team includes an anesthesiologist, nursing staff, and physical therapists for post-surgical rehabilitation.
When to See a Specialist?
You should see a specialist if you experience:
- Persistent heel or calf pain unresponsive to stretching or therapy.
- Limited upward ankle motion affecting walking or running.
- Chronic plantar fasciitis or Achilles tendinitis lasting more than 6 months.
When to Go to the Emergency Room?
Seek immediate medical care if you develop severe swelling, excessive bleeding, numbness, or fever after surgery, which may indicate infection or nerve injury.
What Recovery Really Looks Like?
The first few days involve rest and elevation to control swelling. Gradual mobility and stretching exercises begin under supervision. By 6–8 weeks, patients typically walk comfortably without pain, and most return to full activities—including sports—within 3 months.
What Happens If You Ignore It?
Untreated gastrocnemius tightness can perpetuate chronic plantar fasciitis, Achilles tendon pain, and flatfoot deformity, often worsening over time and limiting mobility.
How to Prevent It?
- Perform daily calf stretches.
- Wear supportive shoes with proper heel height.
- Address early signs of heel or calf pain promptly with therapy.
Nutrition and Bone or Joint Health
A balanced diet rich in protein, calcium, vitamin D, and magnesium supports muscle recovery and bone health post-surgery. Staying hydrated and avoiding smoking enhances healing.
Activity and Lifestyle Modifications
After surgery, maintain a regular stretching program to preserve flexibility and prevent recurrence. Low-impact exercises such as cycling, swimming, and yoga are excellent for strengthening the calf and maintaining long-term results.
