Undergoing hip replacement surgery can be life-changing, offering relief from chronic pain and restoring mobility. However, for the best outcomes post-surgery, patients should understand and follow the “90% rule.”
This guideline is crucial to ensuring safety, avoiding complications, and optimizing recovery after hip replacement.
Here is a brief overview of the 90% rule, its role in protecting your new hip, and how following this guideline can help you regain an active lifestyle.
What Is the 90% Rule in Hip Replacement
The “90% rule” refers to a key precaution for patients who have undergone hip replacement surgery. It advises that, during the initial recovery period, individuals should avoid bending their hip joint past a 90-degree angle. This means keeping your thighs and torso at no less than a right angle when sitting or bending.
This rule is particularly important for patients with a posterior hip replacement, a common type of hip surgery. Maintaining this angle minimizes stress on the new joint, lowering the risk of hip dislocation. A dislocation occurs when the ball portion of the prosthesis slips out of the socket, which can result in pain and require medical intervention.
By following the 90% rule, you protect your new joint and allow the surrounding muscles and soft tissues to heal properly.
Why Is the 90% Rule Important
The following highlights why it is important to follow the 90% rule following a hip replacement.
Reduces Risk of Dislocation
Maintaining a 90-degree angle ensures your hip joint remains stable. It prevents undue pressure on the artificial joint that may cause it to dislocate.
This precaution is especially important in the first six to 12 weeks post-surgery when the joint is most vulnerable.
Supports Proper Healing
After hip replacement surgery, your body needs time to adjust and heal. Following the 90% rule protects the surrounding muscles, tendons, and ligaments while they regain strength and stability.
Aids Long-term Recovery
Adhering to the 90% rule during the early stages of recovery promotes better long-term outcomes. It reduces complications, allowing you to fully enjoy the benefits of your hip replacement, such as reduced pain and improved range of motion.
How to Follow the 90% Rule in Daily Life
Here are a few practical ways you can apply the 90% rule in your day-to-day activities:
Choose the Right Seat
When sitting, use chairs with a firm seat and a height that keeps your hips level or higher than your knees.
Avoid low couches or chairs that cause you to sink down, as this could lead to an unsafe hip angle.
Avoid Deep Bending
Simple tasks like picking up items from the floor can violate the 90% rule. Instead of bending forward at the hips, squat or use a reaching tool designed for hip replacement patients.
Use Assistive Devices
A raised toilet seat can be immensely helpful in maintaining the correct angle when using the restroom. Similarly, tools like sock aids, long-handled shoehorns, and grabbers can help you carry out everyday tasks without bending too far.
Take Care When Getting in and Out of Cars
When entering or exiting a vehicle, avoid twisting your body. Slide into the seat while keeping your legs extended and your body upright. Reverse the process when exiting.
Sleep Smart
Sleep in positions that do not put extra pressure on your hip. Typically, sleeping on your back with a pillow between your legs is safest. Avoid crossing your legs or sleeping on your surgical side.
Tips for a Safe and Speedy Recovery
The following outlines some tips to ensure a safe and speedy recovery after a hip replacement.
Follow Your Doctor’s Advice
Your surgeon will provide specific guidelines tailored to your surgery and recovery needs. Adhering to these instructions, including the 90% rule, is crucial for a successful outcome.
Gradual Rehabilitation
Physical therapy is an integral part of the hip replacement recovery process. Work with your physical therapist to rebuild strength in your hip and surrounding muscles while maintaining the precautions.
Be Patient With Yourself
Recovery after a hip replacement takes time. Do not rush into activities that could strain your new joint. A cautious and steady approach to returning to normal activities will ensure better long-term results.
Build Healthy Habits
Adopting an active but safe lifestyle, along with a balanced diet, will support your recovery. Proper hydration and nutrient-rich meals aid healing and contribute to overall health.
