Types of Knee Replacement

Not all knee replacements are the same. Your surgeon will recommend the best option based on your specific condition.

Total Knee Replacement

The most common procedure. Damaged cartilage and bone from all three compartments of the knee are removed and replaced with metal and plastic components.

  • Best for widespread arthritis
  • Most predictable outcomes
  • 15-20+ year lifespan typical
  • One surgery addresses entire knee

Partial Knee Replacement

Also called unicompartmental replacement. Only the damaged portion of the knee is replaced, preserving healthy bone and ligaments.

  • Smaller incision, less invasive
  • Faster recovery time
  • More natural feeling knee
  • Best for isolated arthritis in one compartment

Your Path Back to Activity

Recovery varies by individual, but here's what most patients can expect after knee replacement surgery.

Day 1-2

Surgery & Hospital Stay

You'll begin physical therapy the day of or day after surgery. Most patients take their first steps within 24 hours.

Week 1-2

Early Home Recovery

Pain decreases gradually. You'll use a walker or cane and start outpatient PT. Many patients can walk short distances.

Week 3-6

Building Strength

Increasing mobility and independence. Most patients transition from walker to cane, then to walking unassisted.

3-6 Months

Return to Activities

Most daily activities resume. Many patients return to golf, swimming, cycling, and other low-impact activities.

1 Year

Maximum Recovery

Full healing achieved. Most patients report they're pain-free and doing activities they couldn't do for years before surgery.
