Ankle osteochondral defects near Fenton are the hidden reason so many ankle “sprains” never fully heal — the cartilage damage only shows on MRI, not plain X-ray. Defect size determines whether it heals with rest or needs arthroscopic repair, and that decision is time-sensitive. Call (810) 206-1402 — ankle cartilage evaluations in Fenton.

Osteochondral Defect Treatment Near Fenton, MI
Ankle osteochondral defect (OCD) treatment near Fenton, MI is available at Balance Foot & Ankle in Howell. Dr. Biernacki DPM treats cartilage lesions with arthroscopic debridement, microfracture, and OATS (osteochondral autograft transfer) for larger defects. Call (810) 206-1402 for ankle cartilage evaluation.
What Is an Ankle Osteochondral Defect?
An osteochondral defect (OCD) is a focal area of damaged cartilage — and sometimes the underlying bone — on the talar dome (the top surface of the ankle’s talus bone). These lesions most commonly result from ankle sprains or fractures that shear or compress the cartilage surface, creating a crater that the ankle’s limited healing capacity cannot repair on its own. The hallmark symptoms are deep ankle pain during activity, catching or locking sensations, and swelling that persists after “healed” ankle sprains. In our Fenton-area patients, talar OCDs are frequently found in patients who had an ankle sprain “that never fully healed” — persistent ankle swelling and pain months after a sprain should prompt MRI evaluation.
Key Takeaway: OCD lesion size guides treatment. Small lesions (<1.5 cm²) respond well to microfracture. Larger lesions (>1.5 cm²) have better outcomes with OATS cartilage transplantation. Untreated OCDs progress to ankle arthritis.
Treatment: Arthroscopy, Microfracture, and OATS
Conservative treatment (immobilization, physical therapy, PRP injection) is appropriate for small, stable lesions — particularly in skeletally immature patients. When conservative care fails: Arthroscopic debridement removes unstable cartilage fragments and smooths the lesion margins, appropriate for small, contained defects. Microfracture — drilling small holes in the subchondral bone — stimulates fibrocartilage repair tissue formation in defects <1.5 cm². OATS (Osteochondral Autograft Transfer System) transplants a cylindrical plug of healthy cartilage and bone from a non-weight-bearing area to fill the defect — the preferred technique for larger lesions (>1.5 cm²), providing hyaline-like cartilage repair with excellent long-term outcomes.
⚠️ See a Podiatrist If:
- Ankle swelling persists more than 3 months after a sprain
- Deep ankle pain during activity that standard sprain treatment hasn’t resolved
- You feel a catching, clicking, or locking sensation in the ankle
- Prior ankle sprain with MRI not yet obtained — many OCDs are invisible on X-ray
- Pain in the ankle that worsens progressively after initially improving post-sprain
AAOS: Osteochondral Lesions of the Talus
