Deciding to undergo a total knee replacement (knee arthroplasty) is a major step toward living without severe joint pain. Whether joint damage stems from osteoarthritis, rheumatoid arthritis, or a prior injury, surgery removes the arthritic joint surfaces—eliminating arthritis in that joint permanently.

However, surgery is only half the equation. Working with a dedicated physical therapist before and after your procedure ensures you recover faster, regain your independence, and return to the activities you love.

At Threshold Physical Therapy & Performance, our Doctor of Physical Therapy (DPT) team provides personalized pre-surgical preparation (prehab) and post-operative rehabilitation for patients across Arvada and Thornton, Colorado.

What Is Total Knee Replacement (TKR)?

During a total knee replacement, an orthopedic surgeon replaces damaged bone and cartilage with specialized medical components:

• Femoral Component: A smooth metal cap placed at the end of the thigh bone.
• Tibial Component: A metal tray and stem inserted into the shin bone, topped with a durable plastic liner for smooth movement.
• Patellar Component: A plastic resurfacing button placed behind the kneecap.

If damage is confined to only one side or area of the joint, a partial knee replacement or patellofemoral replacement may be performed instead.

How Physical Therapy Helps Before & After Knee Surgery

1. Prehab: Preparing Before Surgery

Research shows that completing a six-week exercise program prior to knee replacement significantly improves post-operative pain and mobility scores.

Prior to your procedure, our physical therapists will:

• Build strength in your quadriceps, hamstrings, and upper body to make post-op movement easier.
• Train you on using a walker or crutches confidently.
• Provide home-safety strategies (like clearing trip hazards and setting up seating) to reduce fall risks.
• Help you optimize overall joint flexibility before surgery.

2. Immediate Post-Op Recovery (Weeks 1–2)

Whether you return home the day of surgery or stay overnight, early rehabilitation focuses on restoring safe movement. Your initial care plan includes:

• Swelling & Pain Management: Using targeted ice elevation, soft tissue strategies, and compression.
• Gait & Transfer Training: Learning to safely navigate stairs, get in and out of cars, and transition from sitting to standing.
• Early Mobility: Gentle active bending and straightening exercises to prevent stiffness and joint scar tissue buildup.

3. Advanced Rehabilitation (Weeks 3+)

As healing progresses, your care at Threshold PT transitions toward functional strength and independence:

Can You Delay or Avoid Knee Replacement?

If you suffer from chronic knee pain or early-stage osteoarthritis, formal physical therapy can strengthen supporting joint musculature, improve alignment, and delay or even prevent the need for surgical replacement.
