Understanding the Knee Replacement Procedure
During a total knee replacement, Dr. Schwimley removes the worn or damaged cartilage and bone from your thighbone, shinbone, and kneecap. These are replaced with durable implants made of metal and high-grade plastic, designed to replicate the function of a healthy joint.
Knee replacement may be recommended if you experience:
- Severe pain from osteoarthritis or rheumatoid arthritis
- Chronic stiffness that limits motion
- Difficulty walking, climbing stairs, or performing daily activities
- Pain that persists even at rest or during sleep
For many patients, the decision for surgery follows months or years of conservative treatments such as physical therapy, injections, or bracing that no longer provide relief.
Pre-Surgery Health Optimization
Get Physically Ready
Building muscle strength and improving flexibility before surgery can help you recover faster. Focus on:
- Quadriceps and hamstring strengthening exercises
- Gentle low-impact activities, such as cycling or swimming
- Weight management can reduce strain on your new joint
If you’re currently in a therapy program, continue following your physical therapist’s guidance up to surgery day.
Review Medications and Nutrition
- Discuss all medications and supplements with your surgeon. You may need to stop certain drugs, such as blood thinners or anti-inflammatory medications, before surgery.
- Eat a balanced diet rich in lean protein, whole grains, and vegetables to promote tissue healing.
- If you smoke, try to quit at least several weeks before surgery, as smoking can delay wound healing and increase the risk of infection.
Medical Evaluations
You’ll likely complete a pre-operative evaluation that includes lab work, an EKG, and sometimes chest imaging. This ensures your body is ready for anesthesia and surgery. Patients with chronic conditions like diabetes or hypertension should ensure their condition is well-controlled before the operation.
Understanding the Surgical Journey
Day of Surgery
- The procedure generally takes 1–2 hours.
- You’ll receive anesthesia—either general or regional (spinal/epidural).
- Damaged bone and cartilage are carefully removed, and custom-fitted implants are positioned for optimal alignment and motion.
Immediately After Surgery
Recovery starts right away. Patients typically begin walking with assistance within 24 hours. Early movement prevents blood clots and supports circulation.
Most patients go home the same day or the next morning, depending on their progress and available support at home.
Setting Up Your Home for Success
Proper preparation of your living space can make recovery safer and more comfortable:
| Area | Tips for Preparation |
|---|---|
| Living Space | Move commonly used items to waist height to avoid bending or reaching. |
| Bathroom | Install a raised toilet seat, grab bars, and a shower chair for safety. |
| Sleeping Area | Create a clear path to and from the bed, and ensure adequate lighting. |
| Mobility Aids | Have your walker, crutches, or cane ready and adjusted for height. |
| Support Network | Arrange for a family member or friend to help during the first week post-surgery. |
Making these small adjustments ahead of time can make a major difference once you’re home from the hospital.
The Critical Role of Physical Therapy
Early Movement and Strength Recovery
Physical therapy begins the day of or after surgery. Initially, your therapist will help you with:
- Gentle range-of-motion exercises
- Safe walking techniques with assistive devices
- Strategies for pain management and swelling reduction
Within a few weeks, you’ll progress to exercises that build strength and coordination. By 6–12 weeks, most patients can perform daily activities independently.
Consistent adherence to your rehabilitation plan is key to regaining full motion and function.
Milestones in Recovery
| Timeline | Recovery Goals |
|---|---|
| Week 1–2 | Walk short distances safely, manage pain, and begin home exercises. |
| Week 3–6 | Increase strength and flexibility, and start driving if cleared. |
| Month 3–6 | Resume most normal activities, including low-impact sports. |
Most patients experience noticeable improvements in pain and mobility within the first few weeks and continue to progress steadily.
What to Expect After Surgery
- Pain and swelling are normal but should gradually improve.
- Keep the incision area clean and dry.
- Use ice, elevation, and prescribed medications to reduce inflammation.
- Attend all follow-up appointments with Dr. Schwimley to track progress and prevent complications.
Long-term success depends on your commitment to recovery. Maintaining a healthy weight and active lifestyle will help extend the life of your knee implant, which can last 15–20 years or more.
