ADVANCED SPORTS INJURY CARE

Built for Athletes. Trusted by Active Adults.

Sports medicine is a central focus of our orthopedic practice. We help competitive athletes, recreational athletes, and active adults understand their injuries and choose treatment based on their condition, goals, and lifestyle.

ACL Reconstruction

An ACL tear can affect knee stability, movement, and confidence. Dr. Rieber develops a personalized treatment and reconstruction plan based on the injury, activity level, and return-to-sport goals of each patient.

Rotator Cuff Repair

Rotator cuff injuries can cause pain, weakness, and limited shoulder movement. When surgery is appropriate, arthroscopic repair may be used to restore the damaged tendon and support a structured return to activity.

Shoulder Injuries

We diagnose and treat shoulder conditions including labral tears, instability, impingement, and rotator cuff injuries using conservative care and advanced surgical options when necessary.

Knee Injuries

From ACL and meniscus tears to cartilage damage and persistent knee pain, treatment is focused on restoring stability, function, and confidence in movement.

Arthroscopic and Minimally Invasive Procedures

Arthroscopic techniques allow surgeons to diagnose and treat many joint injuries through small incisions. When appropriate, this approach may reduce disruption to surrounding tissue compared with traditional open surgery.

Sports Medicine for Athletes and Active Adults

You do not need to be a professional athlete to benefit from specialized sports medicine care. Treatment is designed for anyone who wants to remain active, return to exercise, or participate in the sport they enjoy.
