Recommended and Non-Recommended Postures After Total Hip Replacement

Total Hip Arthroplasty (THA) is an effective treatment for end-stage hip osteoarthritis, helping to reduce pain and improve mobility. However, to ensure a smooth recovery and minimize the risk of complications, especially dislocation, adhering to correct postures and avoiding non-recommended postures after surgery is crucial [1].

1. Recommended Postures

Maintaining correct postures helps protect the new hip joint and promotes the healing process.

1.1. When Lying Down

• Lying on your back: This is the safest position after hip replacement surgery, especially during the first 6 weeks [1].
• Using a pillow between your legs: Place a pillow between your legs when lying on your back or side (once cleared by your doctor) to prevent your legs from crossing or rotating excessively, helping to maintain proper hip alignment [1].
• Lying on your side: Only lie on the non-operated side after your doctor's approval, and always place a thick pillow between your legs to keep the hip properly aligned [1].

1.2. When Sitting

• Chair with armrests and appropriate height: Choose a chair that allows your hips to be slightly higher than your knees to avoid bending your hip beyond 90 degrees [1]. Armrests will assist in standing up and sitting down more easily.
• Keep your back straight: Sit upright and avoid leaning too far forward.
• Feet flat on the floor: Ensure both feet are flat on the floor and do not cross your legs [1].

1.3. When Standing and Walking

• Use assistive devices: In the initial phase, use crutches or a walker as instructed by your doctor or physical therapist to maintain balance and reduce weight-bearing on the hip [1].
• Walk slowly and carefully: Avoid sudden twisting movements or walking too quickly.
• Avoid twisting: When turning, move both feet instead of just twisting your upper body to avoid putting pressure on the hip [1].

2. Postures to Avoid

The following postures can increase the risk of hip dislocation, especially in the early post-operative period.

2.1. Avoid Bending Hip Beyond 90 Degrees

This is one of the most important rules. Avoid actions such as deep bending, picking up objects from the floor, squatting, or sitting on very low chairs [1].

2.2. Avoid Crossing or Adducting Legs

Do not cross your legs when sitting or lying down, and avoid excessive adduction of the legs, as this can cause dislocation [1].

2.3. Avoid Internal Rotation of the Hip

Limit inward rotation of the foot and knee, especially when the hip is bent. For patients who underwent surgery using the posterior approach, it is particularly important to avoid combining hip flexion, adduction, and internal rotation [1].

3. Daily Activities to Note

3.1. Dressing and Putting on Shoes

Use assistive devices such as grabbers, dressing sticks, or long shoehorns to avoid excessive bending [1]. Sit on a high chair when dressing and putting on shoes.

3.2. Bathing

Use a shower chair or bench in the bathroom to prevent falls and maintain a safe posture. Use a handheld showerhead instead of bending into the bathtub [1].

3.3. Sexual Activity

Patients should discuss with their doctor the safe time to resume sexual activity and recommended safe positions, usually after several weeks to months depending on individual recovery.

4. General Advice and Importance of Adherence

• Follow medical instructions: Always strictly follow the instructions of your surgeon and physical therapist. Recommendations may vary depending on the surgical approach (anterior, posterior, or lateral) and individual recovery status [1].
• Patient education: Educating patients before and after surgery about safe postures and activities to avoid is crucial to reduce the risk of dislocation [1].
• Patience and practice: The recovery process requires time and patience. Regular practice of correct exercises and postures will help strengthen the muscles around the hip and improve stability.
• Assistive equipment: Using assistive devices such as leg pillows, raised toilet seats, and grabbers can help patients maintain safe postures and increase independence [1].

While some recent studies suggest that strict adherence to hip precautions may not be necessary in all cases, especially for the anterior surgical approach, maintaining safe postures is still widely recommended to minimize risks, especially during the first 6 weeks after surgery [2, 3]. Decisions regarding loosening restrictions should be made by the medical team based on an individual patient assessment.
