What is the 90% rule in Hip Replacement?

When recovering from a hip replacement, it is like learning how to walk again. One key guideline you hear is the 90% rule, but what does it mean? In the context of hip replacement, the 90% rule advises patients to avoid bending their hip joints beyond a 90-degree angle during the early stages of recovery. This is to help minimize the risk of dislocation and ensure that the new joint heals properly.

This article breaks down the practical implications of bending 90 Degrees after hip replacement and addresses common questions about movements like crossing your legs or tying your shoe after surgery.

Common Questions About Hip Replacement Recovery

Hip replacement surgery significantly helps improve mobility and reduces pain, but it also requires patience and care during recovery. Understandably, many patients wonder how quickly they can get back to their daily activities and how soon they can return to specific movements.

Will I have a full range of motion after Hip Replacement ?

A major purpose of hip replacement surgery is to restore mobility. For many patients, this means ease in walking, climbing steps, or performing other daily activities. However, you must manage these expectations.

The surgery addresses the pain and stiffness that the damaged joint has caused, but it does not restore the same range of motion that you had before the joint issues developed. Factors like pre-existing conditions, age, and the type of surgery that is performed influence your outcome. Following the 90% rule is crucial here.

Do not make movements that exceed a 90-degree angle at the hip, like bending over too far or sitting on low surfaces. Physical therapy will help you regain strength and flexibility, but the assurance that you will be back to 100% of your health is unlikely. You will have better movement than when you had the pain, but there is no guarantee that it will be exactly as it was before the pain started.

When can I cross my legs After Hip Replacement ?

Crossing your legs seems harmless, but it can pose a big risk after hip replacement surgery. The 90% rule comes into play here as well. When crossing your legs, you will bend and twist your hips in ways that increase the likelihood of dislocation.

Most surgeons will advise patients to avoid crossing their legs for at least 6-12 weeks after surgery. This time allows your hip joint to stabilize and heal. Even after this period, you must contact your hip specialist doctor in Mumbai.

To avoid the temptation of crossing your legs, consider sitting in chairs with armrests or placing cushions between your legs when you are seated. As you progress with recovery, your muscles strengthen, and you may be able to cross your legs in due time. 

How long After Hip Replacement can I tie my shoe?

Tying your shoe is usually a simple task, but after a hip replacement, you need some time.

Bending to tie your shoe breaks the 90% rule, which is why it is discouraged post-recovery. Patients are advised to wait 10-12 weeks before they can attempt this. At this time, you should use alternatives like slip-on shoes, or slippers or have somebody else tie them for you.

Conclusion

The 90% rule is important in enhancing quick recovery after a hip replacement. Avoiding movements that will bend your hip joint beyond a 90-degree angle helps to cut your knee joint and reduces the risk of complications.

You will have a better chance at a smooth recovery. Activities like crossing your legs or tying your shoe may take time to resume, but patience is key. If you are in doubt, don’t hesitate to reach out to Dr Chirag Patel.
