Approach to care

Athletes are evaluated against the specific demands of their sport and position. The same injury can mean different things to a pitcher, a midfielder and a guard, and the treatment plan reflects that.

Working with professional athletes sets a standard of communication, precision and timeline discipline that Dr. Horner applies to every patient — collegiate, high school, masters and recreational alike.

Return-to-sport decisions are made against objective criteria rather than the calendar alone, in coordination with the patient's therapist, trainer and coaching staff.

Care built around the demands of your sport

The same injury means different things to a pitcher, a midfielder and a guard. Evaluation starts with the sport, the position, the point in the season and what the athlete is trying to get back to, because those factors change both the diagnosis being considered and the treatment worth recommending.

Fellowship training in sports medicine at Rush University Medical Center and experience covering professional athletes with the Chicago Bulls, Chicago White Sox and Chicago Fire set the standard for how these injuries are worked up and communicated. That same standard applies to collegiate, high school, masters and recreational athletes.

Injuries commonly treated

Sports injuries cluster into acute structural injury and overuse. Both are treated here, and the distinction guides how quickly imaging and intervention are appropriate. Joint-specific detail — including surgical technique and recovery timelines — lives on the pages below.

Non-operative and biologic options

Many athletic injuries do not require surgery. Targeted rehabilitation, load management, bracing and time-limited activity change resolve a large share of them, and in-season decisions often weigh whether an athlete can safely finish a season before definitive treatment.

Where biologic treatment is a reasonable option, platelet-rich plasma is discussed honestly — including which conditions it is most reasonable for, what the evidence does and does not show, and the fact that it is self-pay because insurers do not currently cover it.

Return to play

Clearance is a criteria-based decision. Motion, strength symmetry, hop and landing testing, sport-specific movement quality and the athlete's own confidence all factor in, and the criteria are shared with the athlete, their family and their trainer at the outset so the goalposts are clear.

Communication with athletic trainers, therapists and coaching staff is deliberate throughout, and progression is documented in written protocols rather than passed along verbally.

Common questions

How quickly can an injured athlete be seen?

Acute sports injuries are prioritized, with office visits in Oak Brook on Mondays, Little Village on Wednesdays and St. Charles on Thursdays and online booking for each.

Do all UCL injuries need Tommy John surgery?

No. Some partial injuries are managed with rehabilitation, and selected tears in younger throwers are candidates for UCL repair rather than reconstruction, which has a different recovery timeline.

Can I finish my season with this injury?

Sometimes. It depends on the injury, the risk of making it worse and what is at stake in the season. That trade-off is discussed directly rather than decided for you.

Who determines when I can return to sport?

It is a shared decision based on objective testing, made with your therapist, trainer and coaching staff rather than on the calendar alone.
