Joint replacement

Total Knee Replacement

Knee arthritis can cause pain, stiffness, swelling and difficulty with walking, stairs or everyday activities. When symptoms remain limiting despite appropriate nonsurgical treatment, total knee replacement may be an option.

Understanding the Procedure

In a total knee replacement, damaged joint surfaces are removed and replaced with implants designed to restore smooth motion and alignment. At PBNJ, appropriate patients may be treated with Mako robotic-arm assisted technology. A CT-based 3D model is used for planning, and the surgeon guides the robotic arm during the procedure.

Who May Be a Candidate?

A recommendation for surgery is based on the whole clinical picture, not one symptom or X-ray alone. Factors commonly considered include:

  • Pain and stiffness that substantially limit daily activity
  • X-ray evidence of advanced arthritis
  • Symptoms that persist despite appropriate nonsurgical care
  • Goals and overall health that support surgery

Before Surgery

Your evaluation typically includes a medical history, physical examination and imaging. The team will review treatment options, medications, medical optimization, preparation for home, and what to expect after surgery. If surgery is selected, your plan is individualized to your health and functional goals.

Recovery & Rehabilitation

Recovery is progressive. Early goals usually include safe mobility, pain and swelling control, and gradually restoring function. Physical therapy and home exercises are tailored to the procedure and patient. The timing of driving, work, exercise and other activities varies, so follow the instructions provided by your surgeon and therapy team.

Common questions

What Patients Often Ask

Is robotic-assisted surgery performed by a robot?

No. The surgeon performs the operation and guides the robotic arm. The system assists with planning and provides boundaries and feedback during the procedure.

How do I know whether I need replacement?

The decision is based on your symptoms, examination, imaging, response to nonsurgical care, health and goals. An office evaluation is the best way to determine which options are reasonable.

How long is recovery?

There is no single recovery timeline that applies to everyone. Your procedure, health, home situation, rehabilitation progress and activity goals all matter.

Next step

Make an Informed Decision

A consultation is an opportunity to review your imaging, discuss nonsurgical and surgical options, and understand the expected benefits, risks and recovery before deciding how to proceed.

Mako Robotic-Assisted Knee Replacement: What to Know

For selected patients, Mako technology uses CT-based planning and robotic-arm assistance during surgery. The surgeon directs the procedure.

Robotic assistance is a planning and surgical tool; it does not guarantee a particular result or eliminate surgical risks.

Frequently Asked Questions About Knee Replacement

How long does recovery take? Recovery is gradual and varies by health, mobility before surgery and rehabilitation progress. Many patients begin walking with assistance soon after surgery, following their care team’s instructions.

When can I drive? Driving and return to work depend on recovery, medication use, the operated leg and your surgeon’s clearance.
