Hip and Knee Surgery
Dr Sammy Hanna – The Best Orthopedic Surgeon for all types of hip and knee replacement surgeries.
Consultant Orthopedic Surgeon
Total joint replacement is a surgical procedure where parts of an arthritic or damaged joint are removed and replaced with a metal, plastic or ceramic device called a prosthesis or implant. The prosthesis is designed to reproduce the shape and motion of the normal joint.
A joint is an area in the body where two or more bones join together to allow motion. The surfaces of the bones are covered with cartilage to form a normal smooth gliding joint. Over time, this cartilage can break down, leading to bone-on-bone friction which can cause inflammation and pain.
The most common conditions that lead to joint replacement surgery are osteoarthritis and rheumatoid arthritis. There are, however, other causes of joint pain that may also lead to joint replacement including hereditary disorders, developmental problems, and trauma. Joint replacement is performed only after other conservative treatments have failed such as medications, physical therapy, and injections.
What Happens During Joint Replacement Surgery ?
Hip and knee replacement are two of the most commonly performed operations in orthopedic surgery. Both procedures are very successful at eliminating pain, correcting deformities and improving patient mobility so patients can regain quality of life and get back to the activities they enjoy.
During hip replacement, the damaged ball of the hip ball and socket joint is removed and replaced with a metal or ceramic ball that attaches to a stem that fits into the femur. The prosthesis is usually coated with a special material into which the bone will grow over time. In some instances, however, the prosthesis is cemented into the bone. The socket portion of the ball and socket joint is also replaced with a metal cup that is placed into the pelvis. A plastic liner is then snapped into the metal cup and rotates with the new ball on the end of the femoral stem. The prostheses and implants come in a variety of shapes and sizes that can be tailored to the individual.
During total knee replacement surgery, a thin amount of bone along the surface of the joint is removed from the end of the femur or thigh bone, the top of the tibia or leg bone, as well as the underside of the kneecap. The surfaces of the bone are then shaped with tools and sized to allow an appropriate implant fit for each individual knee.
The major ligaments and tendons of the knee are typically kept in place to provide stability and normal motion of the knee joint. Like hip replacements, knee replacements can either be cemented into place or are covered in with a special material into which the bone will grow.
Total joint replacement surgery usually takes one to two hours and is typically performed in a hospital setting with a one- to two-day hospital stay. The procedure is usually performed under spinal anesthesia in combination with a nerve block. This prevents the need for general anesthesia and intubation during the surgery and can help patients avoid many of the side effects of general anesthesia such as post-operative nausea. This allows for better pain control and quicker recovery.
Following the surgery and a short stay in the recovery room, patients will begin walking on the day of their surgery. The majority of patients are then sent home with instructions for further therapy. Typically, patients can return to work and other normal activities within one to three months, depending on their overall health and progress during recovery.
What should I anticipate from the process?
During the operation, your doctor will make incisions in the hip area, remove any damaged components of the hip joint, and then install the prosthesis into the socket of the hip joint. Artificial joint prostheses can be classified as either cementless or cemented. Cementless prostheses are intended to cling to the bone by a porous biological ingrowth, while cemented prostheses are glued to the bone using surgical cement.
Usually, the process takes one hour. On the day of the procedure, you will be mobilised. After spending two to three days under observation in the hospital, you will probably go home to recover. Mr. Mann will make sure to offer advice on how to get the most out of your therapy and recover quickly.
Why is hip replacement surgery necessary?
When treating osteoarthritis and other types of arthritis (of which there are over a hundred), hip replacement surgery is frequently the preferred line of treatment. It is typically used as a last resort when more conservative measures, such as glucosamine, walking aids, painkillers, anti-inflammatory drugs, and physical therapy, are unable to adequately manage arthritic pain.
How much time does it take to recover?
Even while hip replacement patients often recover more quickly than knee replacement patients, a full recovery might still take up to six months. But the amount of time it takes for various people to recover varies greatly; some can heal in as little as one month.
Recovery and the postoperative period
Keep in mind that while the following is a guide to healing, everyone recovers differently and sometimes takes longer. Make use of this knowledge to better comprehend your disease, potential course of therapy, and recuperation. When considering surgery, it’s critical to understand that the durations listed below are minimums and that your healing and recuperation may require more time.
Following your procedure, a regularised enhanced recovery program will start. The following are this program’s primary parallel work streams:
On Day One, mobilisation begins. The frequency of getting in and out of bed increases gradually. The next step involves using the stairs and moving to and from the bathroom/shower. The patient is well-practiced in the exercise regimen prior to release, and the knee should bend to a minimum of ninety degrees. To completely maximise the range of motion of the recently replaced knee, it is crucial to maintain your motivation and continue with your workouts after being released from the hospital.
Will focus more on everyday activities, functional transfers, and home environment adaption.
During the procedure, spinal anaesthesia is employed, along with local anaesthetic infiltration around the hip. Following the procedure, standard oral medicine is administered. If more is needed, request it. Prescriptions that are necessary are given before release.
It’s normal to feel some oozing coming from the wound, especially when you move. You might need to change how you’re dressed. The incision should be dry before discharge, and your practice nurse will make plans for the removal of staples.
Fluids are administered intravenously—that is, straight into the veins—right after the procedure. This method is also used to administer medications, such as regular antibiotics. The production of urine is closely observed. The first postoperative day may need the use of a bedside commode.
The regular diet is started as soon as feasible. Once mobile, the urinary catheter is taken out. Prior to release, bowel habits should also return to normal.
The patient has ablutions at the bedside the first morning following the procedure. Then, showering is progressively introduced: initially with help, then on your own.
