Sports Medicine: Practical Injury Care for Athletes

Got a cut on the field or a sore muscle after practice? Sports medicine is the toolbox athletes use to stay healthy and get back in the game fast. This page focuses on real-world steps you can take right after an injury, how common antiseptics like povidone-iodine fit into care, and when to get professional help.

Povidone-Iodine: What it does and when to use it

Povidone-iodine is a broad-spectrum antiseptic used to reduce germs on skin and minor wounds. Coaches and athletic trainers use it because it’s cheap, easy to carry, and works quickly to lower infection risk. For small cuts and abrasions: rinse the wound with clean water or saline, pat dry, then apply povidone-iodine solution or swab the edges. Cover with a clean dressing if needed.

One practical tip: use it once or twice during the initial cleaning phase rather than continuous daily use. Excessive application on healthy skin can slow healing. For deep puncture wounds, bites, or wounds with embedded debris, don’t try to manage them fully on the sideline—get medical care.

Safe use, limits, and alternatives

Most people tolerate povidone-iodine well, but watch for allergy signs (rash, swelling) or if the athlete has thyroid disease—long-term, large-area use can affect thyroid function. Avoid using strong scrubs on cartilage, eyes, or inside the mouth. For routine wound cleansing, sterile saline is a safe first choice. Chlorhexidine is another option and sometimes preferred for surgical prep; it can be more irritating on open wounds, so check product instructions.

A 2018 study in the Journal of Athletic Training compared simple saline cleaning with antiseptic use for sports-related abrasions and found lower infection rates when antiseptics were used correctly during initial care. That said, follow-up cleaning and keeping dressings clean are just as important as the first treatment.

Beyond antiseptics, sports medicine covers prevention and rehab. Ice, compression, elevation, and timely physical therapy reduce downtime for common injuries like sprains and strains. For concussions, use established return-to-play protocols rather than pushing through symptoms.

When should you see a clinician? If the wound is deep, won't stop bleeding, shows spreading redness, warmth, increasing pain, pus, or the athlete has a fever, get medical attention. Also check tetanus status for cuts from dirty or rusty objects. If you're unsure, err on the side of a quick clinic visit—catching an infection early saves weeks of trouble.
