Evaluation Before Treatment
The evaluation process begins with a detailed consultation with the orthopedic surgeon. The doctor will review the complete medical history of the patient including the duration of joint pain stiffness and limitations in daily activities. They will assess previous treatments like injections or physical therapy. This initial step establishes the need for surgery and identifies any potential risks.
The doctor will explain why Robotic Orthopedics Surgery is the recommended course of action based on this history and perform a physical examination to check range of motion and stability.
The Computed Tomography 256 Slice scanner is an ultra fast CT machine that captures detailed cross sectional images of the bones. In robotic orthopedics this scan is the foundation of the surgical plan. It creates a high resolution 3D model of the hip or knee.
The surgeon uses this model to size the implants and determine the exact angles for bone cuts. The speed of the scan reduces motion artifacts providing crystal clear images of the bony anatomy which is essential for the accuracy of the robot.
3 Tesla MR or 3T MRI represents the gold standard in magnetic resonance imaging for soft tissues. In orthopedics it is used to evaluate the cartilage ligaments and muscles surrounding the joint. It uses a powerful magnetic field to create highly detailed images without radiation.
For knee patients it assesses the status of the ACL and PCL ligaments. For spine patients it visualizes the spinal cord and nerve roots. This precise mapping helps the surgeon rule out other sources of pain that a joint replacement might not fix.
For patients with complex conditions or suspected bone tumors there is a need to check the entire skeleton. Whole Body MRI is a radiation free imaging technique that scans the entire body to detect abnormalities in bones and soft tissues. This is an excellent tool for screening before major surgery ensuring that there are no other lesions that need attention. Knowing the full extent of musculoskeletal health ensures that the surgical plan is appropriate and comprehensive.
EMG or Electromyography assesses the health of muscles and the nerve cells that control them. In patients with spine issues or confusing leg pain this test helps determine if the problem originates from the back or the peripheral nerves. Thin needles are inserted into muscles to record electrical activity. The results tell the surgeon if a nerve is pinched or damaged. This distinguishes between pain caused by a bad hip and pain caused by a pinched nerve ensuring that Robotic Orthopedics Surgery targets the correct problem.
For older patients or those with a history of fractures a bone density scan or DEXA scan is important. This measures the strength of the bones. If the bone is too soft or osteoporotic the surgeon might need to use cemented implants instead of press fit ones. It also influences the rehabilitation plan. Knowing bone quality helps prevent complications like intraoperative fractures and ensures the implant has a solid foundation to hold onto.
Before undergoing robotic surgery patients must undergo a general health clearance. This involves blood tests to check for anemia clotting ability and kidney function. An EKG is performed to check heart health. An anesthesiologist will review the airway and allergy history of the patient. Medications such as blood thinners must be stopped in advance to minimize bleeding risk. This comprehensive assessment ensures maximum safety during the operation and smooth recovery from anesthesia.
Once the Computed Tomography 256 Slice scan is done the data is uploaded to the robotic planning station. The surgeon sits down at a computer to perform a virtual surgery. They size the implant and position it on the screen to restore the natural alignment of the leg. They can see how different implant positions affect the ligament balance. This pre surgical planning phase is what makes robotic surgery so safe and precise because potential problems are solved before the patient enters the room.
In the days leading up to the surgery patients receive specific instructions. This may include exercises to strengthen the muscles around the joint known as prehabilitation. Patients will be told to stop eating and drinking after midnight the night before the surgery. They may be asked to wash with a special antiseptic soap to reduce the risk of infection. Following these rules is critical to prevent complications and to avoid cancellation of the surgery.
The final step in evaluation is ensuring the patient understands the procedure. The surgeon explains the risks benefits and alternatives to Robotic Orthopedics Surgery. They discuss the expected recovery timeline and potential complications. Informed consent is obtained. Patients receive instructions on home modifications and post op care. This open communication builds trust and prepares the patient mentally for the journey ahead.
