| Classification | Clinical Finding | Stress X-ray | MRI Finding | Management |
|---|---|---|---|---|
| Grade I (Functional) | Giving way sensation; no objective laxity on exam | Normal talar tilt (<9°); normal anterior drawer | ATFL intact or minor signal change | Proprioception training; peroneal strengthening; brace |
| Grade II (Mechanical — ATFL) | Positive anterior drawer; mild talar tilt | Anterior drawer >3mm asymmetry; talar tilt 9–15° | ATFL tear; CFL often intact | Structured PT 3–6 months; Brostrom if PT fails |
| Grade III (Mechanical — ATFL + CFL) | Positive anterior drawer + talar tilt; subtalar instability | Talar tilt >15°; anterior drawer >5mm | ATFL + CFL tears; possible osteochondral lesion | Modified Brostrom-Gould procedure; address OCD if present |
| Grade IV (Revision / Severe) | Failed prior Brostrom; global hypermobility; insufficient tissue | Severe laxity on all stress views | Attenuated repaired ligaments; fibular tunnel changes | Allograft / tenodesis reconstruction (Chrisman-Snook or anatomic allograft) |
| Treatment | Indication | Technique | Success Rate | Return to Sport | Key Advantage |
|---|---|---|---|---|---|
| Structured Rehabilitation | Grade I–II; first surgical candidate workup | Peroneal strengthening + proprioception + AFO brace | 85% in first-episode instability | 4–8 weeks | Non-invasive; reverses functional instability |
| Modified Brostrom | Grade II–III; failed 3–6 months PT | Direct ATFL (± CFL) imbrication and reattachment to fibula | 85–92% good-to-excellent | 4–5 months | Anatomic repair; preserves subtalar motion |
| Brostrom-Gould | Grade III; severe laxity; athletes; hypermobility | Brostrom repair + inferior extensor retinaculum augmentation | 90–95% good-to-excellent | 4–6 months | IER reinforcement reduces re-tear risk in high-demand patients |
| Arthroscopic Brostrom | Grade II–III; concomitant intra-articular pathology suspected | Anchor-based ATFL repair via arthroscope; arthroscopy addresses OCD/impingement | 88–93% | 3–5 months | Single procedure for instability + intra-articular lesion |
| Allograft Reconstruction | Grade IV; revision; tissue insufficient; severe hypermobility | Peroneus brevis or gracilis allograft through fibular tunnel and talar neck | 75–85% | 6–9 months | Viable when native tissue inadequate for repair |

The most important clinical decision with Chronic Lateral Ankle Instability Brostrom Gould Repair Michigan Podiatrist isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
What Causes Chronic Ankle Instability?
Lateral ankle sprains are the most common sports injury — approximately 25,000 per day in the United States. Most heal with conservative care, but 20–40% of acute sprains progress to chronic lateral ankle instability (CLAI), characterized by persistent giving-way, a feeling of the ankle “rolling,” difficulty with uneven terrain, and recurrent sprains with trivial provocation. CLAI results from inadequate healing of the anterior talofibular ligament (ATFL) — the primary restraint to anterior talar translation — and often the calcaneofibular ligament (CFL). Concurrent injuries — peroneal tendon tears, osteochondral lesions of the talus, subtalar instability — are present in a significant percentage of CLAI patients and must be identified and addressed.
Conservative Treatment: The Foundation
Before considering surgery, Dr. Biernacki ensures every CLAI patient has completed an adequate trial of conservative rehabilitation. Structured physical therapy for 3–6 months — targeting peroneal muscle strengthening, proprioceptive training, and sport-specific neuromuscular control — successfully manages the majority of ankle instability cases. Rigid ankle bracing (lace-up or semi-rigid) provides mechanical stability during sport. Custom orthotics address any underlying biomechanical contributors (hindfoot varus, hypermobility). Activity modification during acute flares. Surgery is reserved for patients who fail comprehensive conservative rehabilitation with documented functional instability.
The Brostrom-Gould Procedure
The Brostrom-Gould anatomic repair is the most widely performed and best-evidenced surgical treatment for CLAI. Through a lateral ankle incision, the attenuated ATFL and CFL are identified, shortened, and reattached to the fibula using bone anchors — restoring normal ligament tension without sacrificing normal anatomy. The Gould modification reinforces the repair by incorporating the inferior extensor retinaculum, adding a second layer of strength and improving subtalar stability. The Brostrom-Gould procedure preserves full ankle range of motion, has minimal donor site morbidity, and achieves >90% good-to-excellent outcomes in appropriately selected patients.
When Anatomic Repair Is Insufficient
Some patients are not ideal candidates for anatomic Brostrom-Gould repair: those with generalized ligamentous laxity (Ehlers-Danlos syndrome), revision instability after prior failed repair, or severely attenuated ligamentous tissue. In these cases, augmented anatomic repair using an internal brace (suture tape augmentation, InternalBrace technique) or non-anatomic reconstruction with autograft or allograft tendon provides additional mechanical strength. Dr. Biernacki discusses the appropriate technique for each patient’s anatomy, tissue quality, and activity demands.
Recovery and Return to Sport
After Brostrom-Gould repair, patients are non-weight-bearing in a splint for 2 weeks, then progress to a CAM boot for 4 weeks. Physical therapy begins at 6 weeks with range-of-motion and peroneal strengthening, advancing to proprioception and sport-specific training at 10–12 weeks. Most patients return to competitive sport at 4–5 months post-operatively. Athletes augmented with internal brace technique may progress more rapidly (3–4 months for return to sport) due to immediate mechanical reinforcement allowing accelerated rehabilitation.

✅ Pros / Benefits
- Brostrom-Gould achieves >90% good-to-excellent outcomes — one of the highest success rates of any elective orthopedic procedure.
- Anatomic repair preserves full ankle range of motion and normal joint biomechanics — no motion sacrificed.
- Internal brace augmentation allows accelerated rehab with return to sport potentially at 3–4 months.
❌ Cons / Risks
- Patients with generalized hypermobility (Ehlers-Danlos) have higher failure rates with standard Brostrom — augmentation or reconstruction is needed.
- Revision surgery after failed primary repair is significantly more complex — maximizing primary repair success with proper technique is critical.
- Complete recovery to full competitive sport takes 4–5 months — this is not a rapid return procedure.
Dr. Tom Biernacki’s Recommendation
Ankle instability is life-limiting — patients avoid hiking, pick-up basketball, uneven pavement. The Brostrom-Gould procedure is one of the most reliable operations I perform, and the patient satisfaction is very high because we’re restoring something that affects their daily life in real, meaningful ways. The key is selecting the right patients — those who’ve genuinely tried conservative rehab and still have functional instability — and executing the repair with precision.

Frequently Asked Questions
How many ankle sprains before I should consider surgery?
There is no magic number, but recurrent instability (giving-way with normal activities, repeated sprains on trivial provocation) after 3–6 months of structured physical therapy and bracing suggests conservative care has been exhausted. Functional instability — inability to participate in desired activities despite bracing — is the primary indication, not simply number of sprains.
Will I need hardware removed after Brostrom surgery?
No — the bone anchors used to reattach the ligaments to the fibula are typically titanium or bioabsorbable and do not require removal. The internal brace suture tape (if used) also remains permanently. Hardware removal is rarely needed unless a specific complication arises.
Can ankle instability surgery be done arthroscopically?
The ankle joint can be scoped first (arthroscopy) to address concurrent intra-articular pathology (OLT, synovitis, loose bodies) before the open Brostrom-Gould repair is performed through a separate lateral incision. Fully arthroscopic ligament repair techniques exist but are less established than open repair; Dr. Biernacki will discuss which approach is most appropriate.
Is ankle instability surgery covered by insurance?
Yes — Brostrom-Gould repair is covered by most major insurance plans when medically necessary and documented with prior failed conservative treatment (physical therapy records, bracing trial), clinical examination findings, and stress radiographs or MRI confirming ligament laxity.
