Dr. Sartawi’s Innovative PatentedKnee Replacement Technique in Riyadh
Patients considering knee replacement often want to understand not only whether surgery is appropriate, but also which surgical approach may be used.
Dr. Muthana Sartawi performs knee replacement surgery in Riyadh using the Modified Intervastus Approach, an innovative surgical technique developed to preserve important muscles and tendons around the knee.
This patented technique is not robotic-assisted surgery. The surgeon remains responsible for evaluating the patient, planning the procedure, performing the operation and managing the patient’s recovery.
Patients searching for a knee replacement surgeon in Riyadh should receive an individualized assessment before deciding whether total knee replacement, partial knee replacement or another treatment option is appropriate.
When May Knee Replacement Be Considered?
Knee replacement may be discussed when pain, stiffness or joint damage significantly affects mobility and daily activities despite appropriate non-surgical treatment.
An assessment by an orthopedic surgeon in Riyadh may be appropriate when a patient experiences:
Persistent knee pain
Significant stiffness
Difficulty walking or climbing stairs
Reduced mobility
Pain affecting sleep or daily activities
Advanced arthritis or joint damage
Limited improvement after medication, physiotherapy or injections
These symptoms do not automatically mean that surgery is necessary. Every patient requires a clinical assessment based on symptoms, examination findings, imaging and general health.
What Is the Modified Intervastus Approach?
The Modified Intervastus Approach is a surgical method used to access the knee joint during total knee replacement.
It was developed by Dr. Muthana Sartawi and has been described in a United States patent and peer-reviewed medical publications.
The approach is designed to preserve key structures involved in straightening and controlling the knee, including parts of the quadriceps mechanism. It is described as a muscle- and tendon-sparing approach.
The technique may be used during primary total knee replacement when the surgeon determines that it is suitable for the patient’s anatomy and medical condition.
What Has Been Published About the Technique?
The Modified Intervastus Approach was described in the Journal of Knee Surgery by Dr. Muthana Sartawi and his co-authors.
A later retrospective study reviewed patients who underwent total knee replacement using the approach. The publication examined areas such as pain, movement and walking during recovery.
Because the research was retrospective, its findings should not be presented as a guarantee of identical outcomes for all patients. Recovery can be affected by:
The severity of joint damage
The patient’s age and general health
Muscle strength before surgery
Other medical conditions
The type of knee replacement
Participation in physiotherapy
Support available after discharge
The development of complications
What Is Preserved During the Approach?
The muscles and tendons around the knee play an important role in standing, walking and straightening the leg.
The Modified Intervastus Approach is intended to preserve important structures in the knee’s extensor mechanism rather than routinely dividing them to obtain access to the joint.
Preserving these structures may support early movement and rehabilitation. However, the actual surgical plan depends on the patient’s anatomy and the amount of exposure required to perform the operation safely.
The surgeon may need to adapt the approach when additional access to the joint is medically necessary.
Who May Be Assessed for the Technique?
The patented approach is not automatically suitable for every patient.
A knee replacement specialist in Riyadh should assess:
The location and extent of arthritis
Knee alignment
Joint movement
Ligament condition
Previous knee operations
Bone quality
General medical health
Imaging findings
The type of implant and procedure being considered
Patients should not choose a surgical approach based only on online information. The final recommendation must be based on an individualized medical assessment.
How Are Patients Evaluated in Riyadh?
Patients considering knee surgery in Riyadh may begin with an orthopedic consultation.
The assessment may include:
A discussion of current symptoms
Review of previous treatment
Physical examination
Assessment of walking and knee movement
Knee X-rays
MRI or CT imaging when clinically relevant
Review of previous operation reports
Medication and allergy review
Assessment of existing medical conditions
Discussion of the patient’s expectations
Patients should provide recent reports and original imaging files when possible. Sending medical records supports an initial review, but it does not confirm suitability for surgery.

Total Knee Replacement Surgery in Riyadh
Total knee replacement surgery in Riyadh may be considered when arthritis or joint damage affects several areas of the knee.
During total knee replacement, the damaged joint surfaces are prepared and replaced with artificial components designed to recreate the knee’s joint surfaces.
The Modified Intervastus Approach relates to how the surgeon accesses the knee joint. It does not replace the clinical steps required to:
Prepare the damaged bone
Balance the knee
Position the components
Confirm alignment and stability
Close the surgical area
Plan rehabilitation

Total or Partial Knee Replacement
The appropriate knee replacement surgery procedure depends on which parts of the joint are damaged.
Total Knee Replacement
Total knee replacement may be considered when damage affects several areas of the knee.
Some patients search for “complete knee replacement surgery,” but the standard medical terms are total knee replacement and total knee arthroplasty.
Partial Knee Replacement
Partial knee replacement may be considered for selected patients when the damage is limited to one compartment of the knee.
Only the damaged part is replaced, while suitable healthy structures are preserved.
The decision between partial and total knee replacement must be based on examination and imaging rather than on patient preference alone.
Preparing for Knee Replacement Surgery
Preparation may begin several weeks before the planned procedure.
Depending on the patient, the pre-operative process may include:
A complete medical assessment
Blood and urine tests
Heart or respiratory assessment when indicated
Medication and supplement review
Updated knee imaging
Anaesthesia consultation
Specialist clearance for chronic conditions
Planning transport and home support
Preparing a safe recovery area
Arranging physiotherapy
Patients should not stop blood thinners, diabetes medication or other prescribed treatments unless instructed by the treating medical team.

What Happens During Surgical Knee Replacement?
Before the operation, the medical team should explain:
The recommended procedure
Why it is being considered
Available alternatives
Potential benefits
Possible risks and complications
Anaesthesia planning
Pain-management planning
Rehabilitation expectations
Discharge requirements
Follow-up arrangements
During surgical knee replacement, damaged joint surfaces are prepared and artificial components are positioned to recreate the joint surfaces.
The exact steps depend on whether the operation is total or partial, the patient’s anatomy and the chosen surgical approach.
Recovery and Rehabilitation
Recovery differs between patients and should not be presented as a fixed or guaranteed timeline.
Early rehabilitation may involve:
Pain-management medication
Assistance with standing and walking
Use of crutches or a walking frame
Exercises supervised by a physiotherapist
Wound-care instructions
Gradual improvement in movement and strength
Follow-up appointments
Progressive return to daily activities
Full recovery may take several months or longer. Progress depends on the patient’s health, procedure, rehabilitation and individual response.
Selected patients may be assessed for a same-day knee replacement pathway . Same-day discharge is not suitable or guaranteed for every patient.
