Revision Knee Surgery
What is it ?
Revision knee replacement surgery is a highly specialized orthopedic procedure designed to correct or replace a failed or worn-out knee implant that no longer functions properly. Patients seeking care from the best knee revision doctor in Dubai often experience issues such as implant loosening, excessive wear, instability, infection, stiffness, or persistent pain following a previous knee replacement.
Unlike primary knee replacement, revision surgery involves carefully removing the old implant, treating damaged bone and surrounding tissues, and reconstructing the knee using advanced surgical techniques. Specialized titanium components and high-performance joint surfaces are then precisely positioned, sometimes supported by bone grafts, to restore stability, alignment, and smooth pain-free movement.
The incision is closed using refined methods designed to promote healing and recovery. This complex yet highly effective procedure restores joint function, enhances long-term durability, and allows patients to regain mobility and quality of life under the care of the best knee revision doctor in Dubai.
When the surgery is recommended?
Revision knee replacement surgery may be recommended when a previous knee implant no longer functions properly or causes ongoing pain and mobility issues. Patients who typically benefit from revision surgery often experience:
Loosening or wear of the knee implant over time, which may lead to instability or difficulty bearing weight.
Infection around the knee joint, which can damage bone and surrounding tissues and require removal and replacement of the implant.
Knee instability, misalignment, or deformity causing the joint to feel unstable or “give way.”
fractures around the knee joint, which may occur in the bone surrounding the implant due to trauma, falls, or weakened bone over time.
What are the preparation steps for the procedure ?
Before the surgical procedure, the patient undergoes a comprehensive assessment by a specialist in internal medicine and an anesthesiologist. Extensive laboratory tests are conducted to evaluate most of the body’s vital functions to determine the feasibility of performing the surgery.
How its done?
The surgical approach for revision knee replacement depends mainly on the underlying cause of implant failure. In general, there are two main methods used:
Two-stage revision (commonly for infection cases):
Remove the old implant:
The infected or failed knee implant is carefully removed along with any damaged tissue.Insert a temporary spacer:
A special medical-grade spacer is placed inside the knee joint. This spacer delivers antibiotics directly to the area while maintaining joint space and limited movement.Treat the infection:
The patient undergoes targeted antibiotic treatment, which typically lasts up to four to six weeks, until the infection is fully cleared.Reinsert a new knee implant:
Once the infection is eliminated, a new permanent knee replacement is implanted using advanced components.One-stage revision (for non-infection causes):
Remove the old implant:
The worn or loosened knee implant is carefully taken out.Reconstruct and replace the joint:
New specialized implants are inserted in the same surgery, often supported by cones, augments, or other accessories to rebuild bone loss and restore stability.Restore joint movement:
Advanced components recreate smooth joint surfaces to ensure proper alignment and long-term function.
Which Knee Implant Systems will be used?
Revision knee replacement requires specialized implant systems designed to manage bone loss, instability, fractures, and previous implant failure. The choice of implant depends on the cause of revision, bone condition, and overall joint stability. At Dr. Tarabichi’s Center for Joint Care, we provide a full range of advanced revision solutions to meet each patient’s specific needs.
The revision knee implant systems include:
Modular Revision Knee Systems:
Designed to replace failed implants and restore joint alignment and stability. These systems allow flexibility in sizing and configuration to adapt to complex revision cases.
Cones and Augments Systems:
Used to rebuild bone loss caused by fractures, loosening, or previous surgeries. These specialized components provide strong structural support for the new implant.
Rotating Hinge Knee Implant System:
This advanced revision implant is used in complex cases where the knee has severe instability, major ligament damage, significant bone loss, or fractures around the joint. The rotating hinge design connects the thigh bone (femur) and shin bone (tibia) with a secure mechanical hinge that allows controlled bending while still permitting natural rotational movement.
Custom Revision Knee Implants:
In complex cases, customized 3D-designed implants may be created to match the patient’s anatomy and bone defects, ensuring precise fit and optimal joint function.
Robotic and Artificial Intelligence Systems: Available in the operating rooms, Dr. Tarabichi uses robotic and AI technology when needed or requested by the patient.
What About the Pain Management?
Pain is an inherent part of any surgical procedure, and its intensity varies among individuals. We are committed to managing pain effectively and safely, avoiding addiction while ensuring the patient’s recovery is as swift as possible. Our approach includes:
Before Surgery: Based on the patient’s medical history, the most appropriate pain medications are prescribed. Cryotherapy is used several days before the surgery to target specific nerves around the knee responsible for pain. This procedure involves cooling these areas to numb the pain receptors, thus alleviating pain during the recovery period.
During Surgery: The preferred method is spinal regional anesthesia. This is supplemented with sedatives to help the patient relax and sleep during the procedure. This option typically has lighter effects on the body upon waking up.
After Surgery: A small PCA (Patient-Controlled Analgesia) pump is connected to the patient’s IV line, allowing them to control and administer the medication as needed. The medical team closely monitors the patient and provides appropriate medications during their hospital stay. Upon discharge, the patient is given suitable pain medications to aid in their recovery and help them during physical therapy until full recovery.
What About the Surgical Procedure and Recovery Period?
The duration of revision knee replacement surgery can vary significantly and is often difficult to predict in advance. The surgical time mainly depends on the underlying cause of the revision, such as infection, fractures around the knee, bone loss, implant loosening, or joint instability. Some procedures may be completed within a few hours, while more complex cases—especially two-stage revisions for infection—may require longer operative time or multiple surgeries.
Post-operative recovery, on the other hand, differs from patient to patient and is largely influenced by muscle strength, overall physical condition, bone quality, and adherence to the rehabilitation program. Patients with stronger muscles and good physical preparation often recover faster, while those with prolonged joint problems or weakened muscles may require a longer rehabilitation period.
For this reason, each patient receives a personalized surgical and recovery plan designed to ensure the safest procedure and the best possible functional outcome.
What About the Follow Up Visits?
Post-hospital care and follow-up are essential parts of the recovery process. In addition to the customized two-month physical therapy program, our center provides a comprehensive follow-up plan, including periodic visits. The schedule is as follows:
One week after discharge: The first follow-up visit.
Monthly for three months: Subsequent visits to monitor progress.
Annually: An annual check-up.
During these visits, a clinical examination is conducted to assess the patient’s progress. The patient is questioned about their activities, such as walking, climbing stairs, sitting on the floor, and other daily tasks. X-rays are also taken to ensure that the new joint is functioning properly.
What About Rehabilitation After the Surgery?
Physical therapy is the essential phase that complements the surgical procedures, aiming to rehabilitate patients to achieve full mobility, such as kneeling on the ground. This is done under the supervision of highly skilled therapists in this field. Therefore, we advise patients to pay significant attention and commitment to the physical therapy program, which is specifically designed to meet each patient’s physical and functional needs.
To ensure the best possible recovery in the shortest time, we have provided the latest equipment in our physical therapy department. Our goal is to help patients regain muscle and ligament flexibility, strength and pain-free movements in the shortest period
