The most important aspects of hip replacement surgery are safe movement, fall prevention, proper wound care, recognizing signs of blood clots and infection, and following the surgeon’s recommended movement guidelines. Not all hip replacement patients are given the same movement restrictions. Depending on the surgical approach, leg crossing, excessive hip flexion, or certain rotational movements may be temporarily restricted in the early stages. Therefore, the patient’s own discharge instructions are more important than general lists found online.
What is the first priority after hip replacement surgery?
The primary goal is not to move quickly, but to move safely.
In the first few weeks after surgery:
- Muscle strength may not have fully recovered yet.
- The balance may be temporarily disrupted.
- Pain and swelling can alter movement patterns.
- Some medications can cause dizziness or drowsiness.
- The soft tissues surrounding the new prosthesis continue to heal.
Therefore, it is important to use the assistive device for the recommended duration and to perform movements in a controlled manner.
Which movements are prohibited after hip replacement surgery?
There is no single universal list of prohibitions.
Movement restrictions may vary depending on the following factors:
- Using a posterior, anterior, or other surgical approach
- Condition of soft tissues
- Implant stability
- The patient’s muscle strength
- The surgeon’s postoperative protocol
Recommendations Following the Posterior Approach
In some posterior approach protocols, in the early stages:
- Not crossing your legs,
- Avoid bending your hips excessively.
- Avoid excessive rotation of the foot and leg in a particular direction.
It is advisable.
AAOS states that in patients undergoing specific hip restraints, these types of restrictions may be maintained for approximately 6-8 weeks.
However, these recommendations are not automatic for every patient.
Does the 90-degree rule apply to every patient?
No.
The statement “Everyone who has had a hip replacement should avoid bending more than 90 degrees” should not be considered a universally applicable rule for all patients today.
Some surgical approaches may require avoiding excessive hip flexion in the early stages. Different or less restrictive measures may be applied to other patients.
The correct margin should be specified by the surgeon performing the patient’s operation.
How should one sit after hip replacement surgery?
Very low seats can be avoided.
Getting up from very low or sunken chairs can be difficult in the early stages. If the surgeon has movement restrictions, it can also cause excessive hip bending.
An armchair can be helpful.
In the first few weeks, using your arms for support when standing up can help with balance.
Sudden turns should be avoided.
It is safer to change direction with small steps rather than quickly turning the body while keeping your feet on the ground.
Avoid remaining inactive for long periods.
Regular short walks, as permitted by the surgeon, are important for circulation and muscle activity.
How should one sleep after hip replacement surgery?
The patient’s position varies depending on the surgical approach and the surgeon’s protocol.
In some patients in the early stages:
- Lying on your back,
- A pillow between the legs,
- Avoid leaning to one side
It is advisable.
These restrictions may not be necessary for other patients.
Therefore, fixed statements like “you absolutely shouldn’t lie on your side for 6 weeks after hip replacement surgery” are not accurate.
When can I shower after hip replacement surgery?
Shower time:
- Whether the dressing used is waterproof or not,
- Regarding the method of suturing or closing a wound,
- Depending on the condition of the wound,
- To the surgeon’s protocol
It depends.
Risk of Falling in the Bathroom
Wet surfaces are one of the most significant indoor risk areas in the early post-hip replacement surgery.
If necessary:
- Non-slip surface,
- Grab bar,
- Shower chair,
- Help
available.
What should be considered in wound care?
The wound is generally expected to look better each day.
The following changes should be shared with the surgical team:
- Increasing redness
- New or ongoing discharge from the wound site
- The wound opens
- Significantly worsening pain
- Fever or chills
- Bad smell
Not every mild rash means an infection. What matters is whether the condition worsens.
What are the symptoms of blood clots after hip replacement surgery?
Deep vein thrombosis is one of the major complications after hip replacement surgery.
Symptoms to watch out for:
- Rapidly increasing swelling in one leg
- New onset of pain or tenderness in the calf.
- Unexpected color change
- Significant deterioration compared to previous days.
Sudden shortness of breath, chest pain, rapid heartbeat, or feeling faint require immediate evaluation for pulmonary embolism.
How to protect yourself from falls after hip replacement surgery?
Remove loose carpets and rugs.
Small mats on walkways, especially at night, pose a slipping risk.
Light your home well.
Night lighting is useful between the bedroom, toilet, and hallway.
Remove cables from the walkway.
Charging cables, extension cords, and small items can create a tripping hazard.
Do not discontinue the assistive device prematurely.
Using a cane or walker for a few extra days is safer than risking a fall and hip injury.
Use appropriate footwear.
Instead of slippery sandals, shoes that grip the foot and have a secure sole can be preferred.
What should exercise be like after hip replacement surgery?
The goal of the exercise program is:
- Strengthening the muscles around the hips,
- Improving balance,
- Correcting the walking pattern,
- To increase endurance,
- The goal is to ensure a safe return to daily activities.
Excessive exercise can increase pain and swelling. Movements that cause sharp pain should not be forced, and the program should be reviewed by a physiotherapist or surgeon as needed.
Which activities are more suitable after hip replacement surgery?
In the long term, low-impact activities are generally considered more appropriate.
Examples:
- Walk
- Swimming
- Bicycle
- Golf
- Controlled strength exercises
High-impact activities such as running and repetitive jumping can place increased repetitive stress on the implant.
Are antibiotics necessary for dental treatment after hip replacement surgery?
It cannot be said that every prosthetic patient automatically needs to take antibiotics before every dental treatment.
The need for prophylactic antibiotics:
- The patient’s risk of infection,
- Immune status,
- Past prosthesis infection,
- The dental procedure to be performed,
- Current guidelines
This should be evaluated by an orthopedic surgeon and a dentist, taking these factors into consideration.
Antibiotics should not be started on a spontaneous basis.
Are the precautions different after robotic hip replacement surgery?
Mako robotic systems assist surgeons with three-dimensional planning and component placement.
However, even after robotic surgery:
- Wound healing,
- Risk of blood clots,
- Risk of falling,
- Muscle weakness,
- Signs of infection,
- Rehabilitation
It retains its importance.
Robot-assisted surgery does not mean that all post-operative rules are eliminated.
Is the risk of hip replacement dislocation zero?
No. No surgical method completely eliminates the risk of dislocation.
Risk of dislocation:
- Implant location,
- Surgical approach,
- Soft tissue balance,
- The patient’s muscle control,
- Some neurological or anatomical factors
It can have an effect.
Sudden hip pain, a noticeable change in the shape or length of the leg, and inability to move the leg require immediate evaluation.
