Preparing for a knee replacement can feel overwhelming, but understanding the roadmap ahead helps you manage expectations. This procedure involves removing damaged bone and cartilage from your thighbone, shinbone, and kneecap. Surgeons replace those parts with an artificial joint made of metal alloys, high-grade plastics, and polymers. Knowing the details of the surgery and the recovery timeline allows you to plan effectively.
What Happens During Surgery?
The surgical team prepares you for the knee replacement procedure as soon as you arrive at the hospital or surgery center. An anesthesiologist discusses options to keep you comfortable, which often include a nerve block to numb the leg. General anesthesia puts you into a deep sleep, while spinal anesthesia numbs the lower body but leaves you awake. The choice depends on your medical history and the surgeon’s preference.
Once the anesthesia takes effect, the surgeon makes an incision over the front of the knee to access the joint. They carefully remove damaged surfaces of the bone and shape the remaining bone to fit the artificial components. The team then attaches the new metal and plastic parts to create a smooth, functioning joint. This entire process typically takes one to two hours, though complex cases may require more time.
After securing the implant, the surgeon repairs the muscles and tendons around the new joint and closes the incision. You will wake up in a recovery room where nurses monitor your vital signs and pain levels. Most patients start moving their new knee with the help of a physical therapist within hours of the operation.
How Long Is Recovery?
Recovery looks different for everyone, but most patients follow a standard path toward healing. Here is what you can expect as you regain your mobility.
Your Hospital Stay
You will typically stay in the hospital for one to three days, depending on how quickly you progress and the support you have at home. Some patients may even be eligible to return home the same day. During this time, your care team will focus on managing your pain and helping you move early to prevent blood clots.
The Role of Physical Therapy
Physical therapy is a key part of recovery, starting almost immediately after surgery. For the first few weeks, you’ll focus on exercises designed to strengthen your leg and restore your range of motion. While you’ll likely start with a walker or crutches, you will gradually transition to a cane as you feel more stable. Most people return to daily activities like driving or shopping within four to six weeks.
Achieving Full Recovery
Full recovery requires time and consistent effort. While you will likely feel much better after the first month, your body continues to heal internally for up to a year. Be patient with yourself as your muscles regain strength and scar tissue softens. Staying committed to your exercises is the best way to a successful long-term outcome.
What Pain Is Normal?
Pain is a natural part of the healing process as your body adapts to the surgery and the new implant. You will experience soreness and swelling around the incision site and deep within the knee joint. The medical team provides a pain management plan that may include medication, ice therapy, and elevation. Following these instructions helps keep discomfort at a manageable level.
Different types of pain may occur during your rehabilitation:
- Surgical site pain: This feels like tenderness or stinging around the incision and typically fades as the skin heals.
- Activity-related soreness: You might feel aching muscles after physical therapy sessions or after walking for longer periods.
- ** Stiffness:** A tight sensation in the knee is common, especially in the morning or after sitting for a while.
- Night pain: Discomfort often increases at night, making it difficult to find a comfortable sleeping position initially.
Managing these sensations requires a balanced approach of rest and movement. Ignoring pain can hinder your progress, so communicate openly with your therapist. They can adjust your exercises to protect the joint while still promoting strength. Over time, the daily ache diminishes, replaced by the stability of your new knee.
Evaluate a Knee Replacement
Deciding to move forward with surgery requires careful thought and a discussion with an orthopedic specialist. A knee replacement offers the potential for reduced pain and improved mobility for years to come. If conservative treatments no longer provide relief, this procedure might be the right step for your long-term health. Contact a qualified orthopedic surgeon today to schedule a consultation and discuss if a knee replacement aligns with your lifestyle goals.
