South County Orthopedics

Joint pain and injuries shouldn’t keep you from enjoying life. Our orthopedic specialists provide various treatments to help you move freely and live fully again. At Mercy’s South County clinic on Southfork, we treat sports injuries (overuse or traumatic), joint pain, and other orthopedic issues. Our highly trained surgeons, physical therapists, and rehabilitation specialists use the latest techniques and technologies to help restore your quality of life.

Mercy's Orthopedics Clinic in South County now offers walk-in services. We evaluate and treat children (starting at age 10) and adults with orthopedic injuries that have occurred within the past two weeks without being seen by your primary care physician for this injury. This is an excellent choice if you’ve recently experienced a non-life threatening sports injury, sprain/strain/joint injury.


Choose orthopedic walk-in for:

  • Patients 10 and up
  • Acute (new) injuries (fractures, sprains or swollen joints, muscle strains, dislocations, sports injuries) to the foot, ankle, leg, knee, hip, shoulder, arm, elbow, wrist or hand.

Do not choose orthopedic walk-in for:

  • Chronic pain lasting more than two weeks
  • Back pain or injury
  • Head injuries or concussions
  • Open wounds
  • Second opinions
  • Multiple joint injuries
  • Patients with hardware

Orthopedic clinic walk-in hours are Monday - Saturday, 8:00 a.m. - 12:00 p.m. If it is after these hours, please call (314) 543-5284 as we may still be able to offer a same-day appointment.

Our Southfork clinic offers same-day appointments for specific orthopedic injuries and conditions, including:

  • Acute injuries from slips or falls
  • Bone and joint injuries
  • Fractures
  • Sports injuries
  • Muscle strains and injuries
  • Sprains
  • Dislocations requiring reduction (repositioning)

For other orthopedic injuries or concerns, call the clinic to schedule an in-person or virtual visit.

Joint replacement isn’t always necessary to treat damaged knee cartilage. The specialists at Mercy Clinic Orthopedics – Southfork are highly trained and experienced in knee cartilage repair.

Articular cartilage is the smooth, white tissue that covers knee joints to provide lubrication. This cartilage can be damaged by osteoarthritis, injuries, overuse and other conditions. But early detection and treatment can delay or eliminate the need for knee replacement surgery.

Our specialists carefully evaluate your condition and help you find the right treatment options. Your treatment plan may include lifestyle changes, home exercise, physical therapy, knee braces, anti-inflammatory medication, injections, orthobiologics like platelet-rich plasma (PRP) or surgical options.

Contact Dr. Duerr to discuss your options for restoring damaged cartilage. 

Each time you sit, stand, walk or climb stairs, you’re bending your knees. Proper knee alignment balances the weight and stress on your knee joints as you go about these daily activities. When knees aren’t aligned due to inherited conditions or aging, it can cause joint damage and limit movement.

Knee joint preservation surgery restores knee alignment and function. Osteotomy is a surgical procedure that involves cutting the thigh or shin bones and reshaping them to relieve pressure on knee joints. It’s often performed in combination with a cartilage restoration procedure.

Contact Dr. Duerr to find out if you’re a candidate for a knee joint preservation procedure.
