What is Insall Scott Surgery of the Knee?
Insall Scott Surgery of the Knee is named after Dr. John N. Insall and Dr. W. Norman Scott, two pioneers in the field of knee surgery who developed and refined this technique over several decades. They published their first edition of this book in 1984, and since then it has become a classic reference for orthopedic surgeons worldwide.
Insall Scott Surgery of the Knee involves removing the damaged cartilage and bone from the femur (thigh bone), tibia (shin bone), and patella (kneecap) and replacing them with artificial components called prostheses. The prostheses are designed to mimic the shape and function of the natural knee joint, allowing for smooth movement and stability.
The prostheses consist of three main parts: a metal femoral component that covers the end of the femur, a metal tibial component that covers the top of the tibia, and a plastic spacer that fits between them. The patella may also be resurfaced with a plastic button that glides over the femoral component. The prostheses are fixed to the bone with cement or screws.

How to prepare for Insall Scott Surgery of the Knee
Preparing for Insall Scott Surgery of the Knee is an important step to ensure a successful outcome and a smooth recovery. Here are some tips on how to prepare for this surgery:
Preoperative evaluation and planning
Before you undergo Insall Scott Surgery of the Knee, you will need to undergo a thorough preoperative evaluation by your orthopedic surgeon and your primary care physician. This may include:
A physical examination to assess your knee condition, range of motion, strength, stability, alignment, and leg length.
A medical history to review your past and present health problems, medications, allergies, and family history.
A blood test to check your blood count, clotting factors, kidney function, liver function, and infection status.
A urine test to rule out any urinary tract infection or kidney problems.
An X-ray to evaluate the extent of joint damage and bone quality.
A magnetic resonance imaging (MRI) scan to assess the soft tissues around the knee such as ligaments, tendons, muscles, and nerves.
An electrocardiogram (ECG) to monitor your heart function and rhythm.
A chest X-ray to check your lung condition and rule out any respiratory infection or disease.
Based on these tests and examinations, your surgeon will determine if you are a good candidate for Insall Scott Surgery of the Knee. They will also discuss with you the details of the surgery, such as the type and size of prostheses, the surgical approach and technique, the anesthesia options, the risks and complications, and the expected outcome. They will answer any questions or concerns you may have about the surgery.
Preoperative education and counseling
Before you undergo Insall Scott Surgery of the Knee, you will also need to attend a preoperative education and counseling session. This may be conducted by a nurse, a physical therapist, or an occupational therapist. The purpose of this session is to provide you with information and guidance on how to prepare for the surgery and what to expect during and after the surgery. Some of the topics that may be covered in this session are:
The anatomy and function of the knee joint and how it is affected by arthritis or injury.
The goals and benefits of Insall Scott Surgery of the Knee and how it can improve your pain, function, appearance, and quality of life.
The steps involved in Insall Scott Surgery of the Knee and how long it takes to perform.
The types of anesthesia available for Insall Scott Surgery of the Knee and how they work.
The possible risks and complications associated with Insall Scott Surgery of the Knee and how they can be prevented or treated.
Preoperative medication and fasting
Before you undergo Insall Scott Surgery of the Knee, you will need to follow some instructions regarding your medication and fasting. These instructions are important to reduce the risk of bleeding, infection, or anesthesia complications. Some of these instructions are:
You will need to stop taking certain medications that can affect your blood clotting, such as aspirin, ibuprofen, naproxen, warfarin, or clopidogrel. Your surgeon will tell you when and how to stop these medications.
You will need to continue taking your regular medications for other conditions, such as diabetes, hypertension, or thyroid problems. However, you may need to adjust the dose or timing of these medications according to your surgeon's advice.
You will need to avoid taking any herbal supplements, vitamins, or over-the-counter drugs that can interfere with your surgery or anesthesia. Your surgeon will tell you which ones to avoid and for how long.
You will need to fast for at least six hours before your surgery. This means that you should not eat or drink anything, including water, gum, candy, or mints. You may be allowed to take a sip of water with your medications if needed.
How to perform Insall Scott Surgery of the Knee
Insall Scott Surgery of the Knee is performed in a hospital or an ambulatory surgery center. The surgery usually takes about one to two hours to complete. Here are the main steps involved in this surgery:
Anesthesia and positioning
Before the surgery begins, you will be given anesthesia to numb your pain and make you comfortable. You may receive one of the following types of anesthesia:
General anesthesia: This involves inhaling a gas or receiving an injection that makes you unconscious and unaware of the surgery. You will also receive a nerve block to numb your leg and reduce postoperative pain.
Spinal anesthesia: This involves receiving an injection in your lower back that numbs your lower body. You will also receive sedation to make you relaxed and sleepy.
Epidural anesthesia: This involves receiving an injection in your lower back that numbs your lower body. A thin tube is inserted into your epidural space and connected to a pump that delivers a continuous dose of anesthesia throughout the surgery. You will also receive sedation to make you relaxed and sleepy.
After you receive anesthesia, you will be positioned on the operating table with your knee exposed. Your leg will be placed in a special device that holds it steady and allows for precise alignment of the prostheses.
Surgical approach and exposure
The next step is to make an incision on your knee to access the joint. There are different types of incisions that can be used for Insall Scott Surgery of the Knee, such as:
Medial parapatellar approach: This involves making a vertical incision along the inner side of the kneecap and lifting it up to expose the joint.
Lateral parapatellar approach: This involves making a vertical incision along the outer side of the kneecap and lifting it up to expose the joint.
Midvastus approach: This involves making a vertical incision along the inner side of the thigh and splitting the muscle fibers of the vastus medialis muscle to expose the joint.
Subvastus approach: This involves making a vertical incision along the inner side of the thigh and lifting the muscle fibers of the vastus medialis muscle without splitting them to expose the joint.
Quadriceps-sparing approach: This involves making a vertical incision along the inner side of the thigh and avoiding cutting or lifting any muscle fibers to expose the joint.
The choice of incision depends on several factors, such as your anatomy, preference, surgeon's experience, and type of prosthesis. The goal is to minimize tissue damage and blood loss while providing adequate exposure and access to the joint.
Prosthetic implantation and alignment
The next step is to remove the damaged cartilage and bone from the femur, tibia, and patella using special instruments such as saws, drills, chisels, and rasps. The amount of bone removed depends on the extent of joint damage and the size of prosthesis. The goal is to create a smooth and even surface that matches the shape and size of the prosthesis.
After the bone is prepared, the prosthesis is implanted and fixed to the bone using cement or screws. The prosthesis consists of three main parts: a metal femoral component that covers the end of the femur, a metal tibial component that covers the top of the tibia, and a plastic spacer that fits between them. The patella may also be resurfaced with a plastic button that glides over the femoral component.
The alignment of the prosthesis is checked using special instruments such as rulers, gauges, and lasers. The alignment is crucial for the function and longevity of the prosthesis. The goal is to achieve a neutral or slightly outward position of the knee, with equal gaps between the femur and tibia on both sides.
Wound closure and dressing
The final step is to close the incision and apply a dressing to the wound. The incision may be closed using sutures, staples, or glue. The dressing may consist of gauze, bandages, or adhesive strips. The dressing protects the wound from infection and bleeding and promotes healing.
How to recover from Insall Scott Surgery of the Knee
Recovering from Insall Scott Surgery of the Knee is a gradual and progressive process that requires your active participation and cooperation. Here are some tips on how to recover from this surgery:
Postoperative pain management and mobilization
After the surgery, you will be transferred to a recovery room where you will be monitored for any signs of complications or adverse reactions to anesthesia. You will also receive pain medication to control your postoperative pain. You may receive one or more of the following types of pain medication:
Oral medication: This involves taking pills or liquids by mouth that reduce pain and inflammation, such as acetaminophen, ibuprofen, naproxen, or opioids.
Intravenous medication: This involves receiving medication through a vein that reduces pain and inflammation, such as ketorolac, morphine, or fentanyl.
Nerve block: This involves receiving an injection near a nerve that numbs your leg and reduces pain, such as femoral nerve block or sciatic nerve block.
Patient-controlled analgesia (PCA): This involves using a device that allows you to self-administer a dose of medication through a vein by pressing a button, such as morphine or fentanyl.
The type and dose of pain medication depends on your level of pain, medical history, allergies, and preference. The goal is to keep your pain at a tolerable level while avoiding side effects such as nausea, vomiting, constipation, drowsiness, or respiratory depression.
As soon as you are able to, you will be encouraged to start moving your leg and walking with the help of a walker, crutches, or cane. You will also be taught some exercises to do in bed or in a chair to improve your blood circulation, prevent blood clots, and maintain your muscle strength and joint motion. You may also receive some devices to assist your mobilization, such as a continuous passive motion (CPM) machine that moves your knee gently through a range of motion, or an ice machine that cools your knee and reduces swelling.
Postoperative rehabilitation and physiotherapy
After you are discharged from the hospital or surgery center, you will need to continue your rehabilitation and physiotherapy at home or at an outpatient clinic. You will be given a personalized exercise program that includes stretching, strengthening, balance, and functional exercises for your knee. You will also receive some instructions on how to care for your wound, prevent infection, manage swelling, use assistive devices, and resume your daily activities.
