Knee Replacement

Replacing damaged knee joint surfaces with implants to relieve arthritis pain and restore mobility.

• More than 790,000 knee replacements are performed in the United States each year, according to the American College of Rheumatology.
• Performed with the ROSA robotic system for greater implant precision.
• Same-day discharge is available for qualifying patients.
• Partial knee replacement is offered when damage is limited to one compartment.
• Revision surgery for failed or worn implants is handled here too.

Robotic-Assisted Knee Surgery

Robotic-assisted surgery (Mako, ROSA) for more precise implant placement.

Knee Arthroscopy

Minimally invasive keyhole surgery to diagnose and treat knee problems through small incisions.

• Knee arthroscopy is one of the most common orthopedic procedures in the United States, with an estimated 750,000 performed each year.
• Meniscus repair is often done arthroscopically here.

Total Knee Replacement

Full replacement of the knee joint, the standard for advanced arthritis affecting the whole knee.

• Performed with the ROSA robotic system for greater implant precision.
• Same-day discharge is available for qualifying patients.

Partial Knee Replacement

Replacing only the damaged compartment, preserving healthy bone for a faster recovery.

• Performed with the ROSA robotic system for greater implant precision.
• Same-day discharge is available for qualifying patients.

Non-Surgical Knee Treatment

Injections (gel, PRP, cortisone), therapy, and other options to treat knee pain without surgery.
