Seeing a sports medicine doctor for a concussion is essential for expert management of traumatic brain injuries and ensuring a safe, guided return to sports, work, or school.

Why see a sports medicine specialist for a concussion?

- Specialized Management: Expertise in recognizing subtle or delayed symptoms to help prevent prolonged recovery.
- Safe Return-to-Play Protocols: Structured, step-by-step plans that reduce the risk of a second, more severe concussion.
- Comprehensive Evaluation: Assessment of cognitive function, balance, and coordination to detect potential long-term issues.
- Prevention of Long-Term Complications: Careful management to help avoid post-concussion syndrome (PCS) or Chronic Traumatic Encephalopathy (CTE).
- Individualized Care: Personalized treatment plans based on age, sport, and specific symptoms—especially important for young athletes.

At Orthopedic Performance Institute, our sports medicine specialists, Dr. Justin Riojas and Dr. Alexandra Matthews, provide comprehensive concussion evaluations and baseline testing for athletes of all ages. Call (210) 545-7171 to schedule.

Did you know that regular exercise or physical activity is important to building and maintaining bone health because inactivity can cause loss of bone?

That's right! Exercise works on bones much like it works on muscles — it makes them stronger. Exercise is important for building strong bones when we are younger, and it is essential for maintaining bone strength when we are older. Because bone is living tissue, it changes over time in response to the forces placed upon it. When you exercise regularly, your bone adapts by building more bone and becoming denser. This improvement in bone requires good nutrition, including adequate calcium and Vitamin D.

Another benefit of exercise is that it improves balance and coordination. This becomes especially important as we get older because it helps to prevent falls and the broken bones that may result. Adults need at least 30 minutes 5 days a week, or any other combination that works for you.

At Orthopedic Performance Institute, injections can serve both a diagnostic and therapeutic purpose for a variety of hip, shoulder, and knee conditions. Common issues we treat include osteoarthritis, rheumatoid arthritis, labral tears, muscle tears, ligament injuries, and tendinopathies.

Using ultrasound guidance, our specialists are able to precisely deliver corticosteroids, hyaluronic acid, or advanced therapies such as Platelet-Rich Plasma (PRP) exactly where they’re needed.

The benefits of ultrasound-guided injections include:
- Accurate placement of medication at the intended site
- Greater precision for improved effectiveness
- Less discomfort compared to “blind” injections
