Knee Replacement


A person’s quality of life can be greatly impacted by knee discomfort, which can make even basic tasks like walking or climbing stairs hard. When conservative therapy is unable to provide relief, knee replacement surgery becomes a possibility. Many people’s lives have been changed by this surgery, which has helped them regain their movement and reduce their discomfort. The procedure, advantages, and recuperation period of knee replacement surgery will all be covered in this article.

Procedure of Knee Replacement Surgery

Knee arthroplasty, the surgical procedure for replacing the knee, consists of multiple phases. 

Below is a summary of the standard operating procedure:

Preoperative Evaluation: The orthopedic surgeon will undertake a complete evaluation of the patient’s medical history, physical examinations, blood tests, and imaging tests (such as MRI or X-rays) prior to the surgery. This makes sure the patient is a good candidate for surgery and aids in assessing the degree of knee damage.

Anesthesia: General anesthesia is frequently used during knee replacement surgery, meaning the patient is unconscious throughout the procedure. As an alternative, the patient may be kept awake and have the lower body completely numbed using localized anesthesia, such as an epidural or spinal block.

Incision: Once the anesthetic is delivered, the surgeon creates an incision above the knee joint, typically 8 to 12 inches in length. Depending on the particular surgical technique and the surgeon’s preference, this incision may be curved or vertical.

Joint Exposure: To reveal the knee joint, the surgeon gently separates tendons, muscles, and other soft tissues. This makes it possible to see and reach the injured knee components clearly.

Reshaping of Bones: The femur, or thigh bone, and tibia, or shin bone, which make up the knee joint, have their diseased surfaces removed by the surgeon using specialized surgical equipment. This technique of reshaping makes room for synthetic implants.

Implant Placement: The freshly prepared bone surfaces are used to receive ceramic or metal implants. The femoral and tibial implants are made up of many parts, with a plastic spacer frequently positioned in between. These parts imitate the knee joint’s natural form and functionality.

Patellar Resurfacing: The surgeon may decide to use a plastic component to resurface the patella, depending on the state of the kneecap. By taking this step, the patella’s smooth movement within the joint is improved.

Testing and Adjustments: The knee joint is carefully moved and tested through its range of motion by the surgeon to ensure correct alignment and stability of the implants. Adjustments are performed as needed to ensure the best possible fit and functionality.

Closure of the Wound: The surgeon uses stitches or staples to seal the incision after making sure the implants are positioned correctly. The wound is covered with a sterile covering.

Postoperative Care: After surgery, the patient is brought to a hospital room and then to a recovery area. Physical rehabilitation, pain management, and postoperative monitoring usually start shortly after surgery.

Benefits of Knee Replacement Surgery

Knee replacement surgery, sometimes referred to as knee arthroplasty, has several advantages for people with persistent knee discomfort and limited mobility. 

The following are some major advantages of knee replacement surgery:

Pain Relief: Artificial implants are used to replace damaged joint surfaces during knee replacement surgery, hence relieving pain. This improves the comfort and quality of life for patients by removing chronic knee pain brought on by arthritis or injury and enabling them to continue their regular activities.

Increased Mobility: By reestablishing joint stability, function, and mobility, knee replacement surgery increases mobility. With ease, patients can walk, climb stairs, and carry out daily duties. People may now move freely, participate in physical activities, and live more independently thanks to the new prosthetic knee joint.

Improved Quality of Life: Having a knee replacement considerably raises one’s level of health and happiness. It improves mobility, reinstates functionality, and eliminates chronic knee pain, enabling people to resume social activities, regain their independence, and feel better overall.

Long-Term Durability: One important advantage of knee replacement surgery is its long-term durability. Modern implants can offer relief for more than 15 to 20 years, guaranteeing an extended time of better quality of life before the need for revision surgery may arise. 

Improved Sleep and Mental Health: Following knee replacement surgery, sleep and mental health are enhanced. Pain relief and increased mobility all contribute to psychological well-being by improving sleep quality, mental health, and optimistic outlook.

Joint Stability and Alignment: By addressing these problems, the procedure lowers the chance of subsequent damage and complications from knee replacement surgery. Better mobility, functionality, and a decreased chance of falls or other related problems are all made possible by restoring stability and alignment.

Recovery from Knee Replacement Surgery

Following knee replacement surgery, recovery is a long process that calls for patience and following postoperative instructions. 

The following are some crucial elements of the recuperation phase:

Hospital Stay: Following knee replacement surgery, patients are admitted to the hospital for a few days in order to receive pain relief and monitoring. This is when physical therapy starts, starting with exercises for knee replacement and mobilization.

Pain Control: During the healing process following a knee replacement, pain control is crucial. Medications are frequently administered to help control pain, including oral pain medications and/or spinal anesthesia. The need for pain medication typically decreases as healing advances.

Physical therapy and rehabilitation: Following surgery, these services begin as soon as possible and last for several weeks or months as outpatients. Patients who have knee replacements can increase their knee strength, range of motion, and flexibility with the help of therapists. Initially, crutches or walkers may be utilized as assistive equipment.

Activity Levels progressively Increase: With an emphasis on aided walking and rehabilitation exercises, activity levels progressively rise. As the knee strengthens, patients can resume their regular activities and stay away from stressful or high-impact sports.

Bruising and Swelling: Following surgery, bruising and swelling are typical. Compression stockings, leg elevation, and ice packs all aid in reducing swelling. For wound care and edema management, it is imperative that you adhere to the surgeon’s instructions.

Recuperation Time: A total knee replacement requires several months to heal, during which time pain, range of motion, and strength gradually improve. Following instructions, going to physical therapy, and taking prescription drugs as directed are essential.

Long-Term Follow-Up: Schedule regular follow-up visits with the surgeon to discuss problems, evaluate knee healing, track recovery progress, and receive advice on returning to activities and long-term knee care.

Alternatives to Knee Replacement Surgery

Depending on the patient’s circumstances and the extent of the knee issue, a number of alternatives to knee replacement surgery may be taken into account. Among the typical substitutes are:

Medication: Painkillers, corticosteroid injections, and nonsteroidal anti-inflammatory medications (NSAIDs) can all be used to treat and lessen knee discomfort and inflammation.

Physical treatment: A well-designed physical therapy program can reduce discomfort, increase flexibility, and strengthen the knee’s surrounding muscles.

Assistive Devices: You can support your knee joint and lessen the strain on the injured area by using walking aids, braces, or orthotics.

Lifestyle Changes: Reducing pain and pressure on the knee joint can be achieved by eating a nutritious diet and exercising regularly.

Regenerative medicine: New therapies like prolotherapy and stem cell therapy are being investigated as possible substitutes for knee replacement surgery. These therapies support tissue regeneration and activate the body’s innate healing mechanism.
