Are you considering knee replacement surgery? This procedure, known as knee arthroplasty, can significantly improve your quality of life by alleviating chronic knee pain and stiffness. Knee replacement surgery involves replacing the damaged parts of your knee joint with artificial implants. Let’s delve into what you need to know about this surgery.
Who is a Candidate for Knee Replacement Surgery?
Not everyone requires knee relief surgery. Generally, it’s considered a last resort after conservative treatments like pain medication, physical therapy, and injections prove ineffective. Ideal candidates typically experience:
- Severe knee pain: Constant pain significantly impacts daily activities like walking, climbing stairs, or getting up from a chair.
- Stiffness: Restricted knee movement that hinders your ability to bend or straighten the joint.
- Limited function: Difficulty performing everyday tasks due to knee pain and stiffness.
- X-ray confirmation of advanced arthritis: Worn-out cartilage and bone degeneration visible on X-rays.
Types of Knee Replacement Surgery
There are two main types of knee replacement surgery, depending on the extent of damage:
- Total knee replacement: This procedure replaces all the weight-bearing surfaces of the knee joint with metal and plastic implants.
- Partial knee replacement: This option targets a specific knee joint section, typically when arthritis is isolated to one area.
What to Expect During Knee Replacement Surgery
Knee replacement surgery is typically performed under general anaesthesia. Here’s a general overview of the process:
- Incision: The surgeon makes an incision over the knee to access the joint.
- Bone removal: Damaged cartilage and bone are removed from the femur (thighbone), tibia (shinbone), and sometimes the patella (kneecap).
- Implant placement: The surgeon positions the artificial joint components of metal and plastic to restore proper alignment and function.
- Wound closure: The incision is then closed with sutures or staples.
The entire procedure usually takes one to two hours.
Recovery after Knee Replacement Surgery
Recovery after knee substitute surgery is an ongoing process that requires dedication and patience. Key aspects include:
- Physical therapy: A crucial component of recovery, physical therapy helps regain strength, flexibility, and range of motion in your knee.
- Pain management: Medication can help manage post-surgical pain, allowing you to participate actively in your recovery.
- Weight management: Maintaining a healthy weight reduces stress on your new knee joint.
Risks and Complications of Knee Replacement Surgery
While knee alternate surgery is a successful procedure for many, it’s essential to understand the potential risks and complications involved. Here’s a closer look:
- Infection: As with any surgery, there’s a risk of infection at the incision site or within the joint.
- Bleeding: Blood clots can develop in the legs after surgery, potentially travelling to the lungs (pulmonary embolism).
- Stiffness: While physical therapy helps, achieving a full range of motion after surgery can be challenging for some patients.
- Component loosening or wear: Over time, the artificial joint components may loosen or wear, potentially requiring revision surgery.
- Nerve damage: There’s a small risk of injury to nerves surrounding the knee joint, which can cause numbness or weakness.
Considering Alternatives to Knee Replacement Surgery
If you’re apprehensive about knee substitute surgery, explore alternative treatment options your doctor might suggest:
- Weight loss: Shedding excess pounds significantly reduces stress on the knee joint, potentially delaying or even eliminating the need for surgery.
- Activity modification: Adjusting your activities to minimize stress on the knee can help manage pain and improve function.
- Assistive devices: Canes, walkers, or knee braces can provide additional support and stability.
- Cortisone injections: Injections can offer temporary pain relief and reduce inflammation.
How to Prepare for Knee Replacement Surgery
Once you and your doctor decide knee replacement surgery is the best course of action, proactive preparation goes a long way toward a smooth recovery:
- Educate yourself: Learn as much as possible about the surgery, recovery process, and potential risks.
- Optimize your health: Address any pre-existing medical conditions that could complicate surgery.
- Strengthen your muscles: Building strength in the muscles surrounding your knee improves post-surgical rehabilitation.
- Arrange for home care: Consider having someone assist you with daily tasks during the initial recovery period.
