Knee replacement operation, or knee arthroplasty as it is also called, is a surgery initiated to replace damaged or diseased knees with artificial joints. This procedure is often recommended for people who have severe knee pain and stiffness that limit their movement because of such conditions as osteoarthritis, rheumatoid arthritis, post-traumatic arthritis among others caused by degenerative joint diseases.
1. Planning for the Procedure:
Patients are taken through various preparatory stages before they undergo knee replacement surgery.
Medical Checkup:
The orthopedic surgeon will perform a comprehensive medical assessment which involves physical examination, reviewing your medical history and carrying out diagnostic tests like X-rays, MRIs and blood tests.
Consultation and Consent:
Your doctor will explain what will be done during the surgery session; they will talk about possible risks as well as benefits on them too then give room for any questions you may wish to ask while seeking clarification where necessary. You are required to give your consent after being given all this information.
Instructions before Operation:
Individuals might have to discontinue certain drugs depending with their nature, stop eating or drinking anything within a specified time before the surgery and make arrangements for how they will be taken care of after the procedure has been done so that rehabilitation can start right away.
2. Surgical Procedure:
Usually, knee replacement surgery is performed under general anesthesia or spinal anesthesia. The type of anesthesia used depends on the overall health of the patient and the preference of the surgeon. The following are some important steps in this process.
Incision:
To reach the injured joint, a cut is made over the knee by the surgeon.
Reshaping the Bone:
For accommodating artificial implants, either they remove or reshape damaged sections of thigh bone (femur), shinbone (tibia) or kneecap (patella).
Implant Placement:
After that metal or plastic prosthetics are attached to prepared bone surfaces with cement made up from bones itself or press-fit technique can also be employed; these duplicates natural shape and function of knee joint.
Closure:
When necessary devices have been implanted through an incision site, it is sewn up using stitches which are later removed when healed completely but before that sterile dressing may be applied for preventing infection caused due to exposure towards external environment while healing takes place internally within body itself without any contact from outside air currents such as those found outdoors during different seasons where temperature changes occur frequently throughout year.
3. Recovery and Rehabilitation:
A structured rehabilitation program will be undergone by patients after having undergone knee replacement surgery so as to aid in quickening recovery process, restoring movement ability around operated part as well as strengthening muscles adjacent thereto. Normally this includes.
Hospital Stay:
Following operation most people are kept in hospitals few days for monitoring purposes and early stages of rehabilitation.
Physical Therapy:
A physical therapist will collaborate with patients to perform gentle exercises, increase range of motion, and progressively intensify weight-bearing activities.
Pain Management:
Pain medication may be prescribed for postoperative discomfort. Patients are advised to apply cold packs and raise the leg to reduce swelling.
Home Exercise Program:
Patients will receive instructions about particular exercises they can do at home that will help them keep getting better and make their knee stronger and more flexible.
4. Risks and Complications:
Although generally safe and effective, knee replacement surgery carries potential risks and complications such as:
Infection:
There is a chance of acquiring surgical site infection which might call for antibiotics or any other necessary treatment.
Blood Clots:
Following the operation, blood clots in legs (deep vein thrombosis) or lungs (pulmonary embolism) may necessitate medication thinning the blood or other interventions.
Implant Wear or Loosening:
Artificial implants can wear out over time or become loose thereby requiring revision surgery.
Nerve or Blood Vessel Damage:
Sometimes nerves close by or vessels could get injured during the operation though it is rare.
5. RESULTS IN THE LONG RUN:
For most patients, knee replacement surgery comes as a relief from pain and inability to move around. Depending on age, overall health status, and the amount of damage done to the joint, recovery may be unique for each individual. When proper care is taken with following postoperative guidance, people usually expect their new knees last for at least fifteen years.
In summary, these findings indicate that knee replacement surgery should not only be seen as an option for those who suffer from severe knee pain or dysfunction but also as a way through which they can regain independence and mobility. This can be achieved by learning about the operation it self participating in rehabilitation programs; adhering to post-operative recommendations among others.
