Knee Replacement Process
$375k Won for a Motorcycle Accident
Despite its widespread use, knee replacement surgery sometimes leads to unexpected complications. Studies suggest that up to 20% of patients who undergo knee replacement surgeries may experience issues such as implant failure or infection. At Muller Brazil, we understand the challenges individuals face when knee replacement surgeries result in serious injuries or prolonged pain. We're here to provide clear, compassionate, and informative assistance every step of the way.
Knee replacement surgery, also known as knee arthroplasty, is a procedure to replace damaged or diseased parts of the knee joint with artificial components. The surgery typically involves 4 main steps:
- Preparation: Before the surgery, the patient undergoes a thorough evaluation, including medical history review and physical examination. Imaging tests, such as X-rays and MRI scans, may be conducted to assess the extent of damage to the knee joint.
- Anesthesia: During the surgery, the patient is placed under general anesthesia or regional anesthesia, depending on their medical condition.
- Implantation: The surgeon makes an incision in the knee to access the damaged joint. The damaged bone and cartilage are then removed, and the artificial components, including the metal and plastic implants, are securely placed to restore the knee's function and stability.
- Recovery: After the surgery, the patient is closely monitored in the recovery room before being transferred to a hospital room or outpatient facility. Physical therapy and rehabilitation are required in the recovery process.
Knee replacement surgery is an attractive option to relieve pain and improve quality of life. As any other surgery, it also carries risks, including infection, blood clots, and implant failure.
Long-Term Use Issues
$190k Won for a Slip & Fall
While knee replacement surgery relieves pain and improves mobility, long-term use of knee implants may present complications. Some individuals may experience issues such as:
Implant Wear and Tear
Over time, the artificial components of the knee implant may wear down, leading to reduced effectiveness and potential need for revision surgery.
Implant Loosening
In some cases, the bond between the implant and the bone may weaken over time, resulting in implant loosening. This causes pain, instability, and decreased function of the knee joint.
Infection
Despite precautions taken during surgery, there is a risk of developing an infection in the knee joint, which can lead to serious complications and may require additional treatment or surgery.
Chronic Pain
While many patients experience relief from knee pain following surgery, some individuals may continue to experience chronic pain in the operated knee due to various factors such as nerve damage or improper implant placement.
Revision Surgery
In cases where the initial knee replacement surgery fails or complications arise, revision surgery may be necessary to correct the issue and improve the function of the knee joint.
Individuals who have undergone knee replacement surgery should be aware of these potential long-term use issues. It goes without saying that seeking medical attention for persistent pain, instability, or other concerning symptoms after surgery is a given.
Injuries and Side Effects
$150k Won for a Defective Knee Implant
Knee replacement systems enhance mobility and improve the quality of life for individuals with knee injuries or age-related wear and tear. While many patients experience relief from pain and increased mobility, others may face complications. Complications from a defective knee implant may include:
- Pain, Bruising, or Swelling of the Knee: Some individuals may experience persistent pain, bruising, or swelling in the knee following surgery.
- Infection of the Knee Joint: Infections can occur in the knee joint, leading to serious complications if not promptly treated.
- Blood Clots in the Lower Leg: Blood clots can form in the lower leg, posing a risk of clot migration and potentially life-threatening conditions such as pulmonary embolism.
- Nerve and Blood Vessel Damage: Damage to nerves and blood vessels surrounding the knee joint results in numbness, tingling, or loss of sensation.
- Dislocation of the Knee Joint: Improper implant placement or other factors may lead to dislocation of the knee joint, requiring medical intervention.
- Difficulty Moving: Some individuals may experience difficulty moving the knee joint due to pain, stiffness, or other complications.
- Implant Loosening: Weak bond between the implant and the bone results in implant loosening, causing instability and discomfort.
- Cracking or Fracture of Components: Components of the knee implant may crack or fracture, requiring surgical intervention to address.
- Fractures in Bone Surrounding Implant: Fractures may occur in the bone surrounding the implant, further complicating the situation.
- Metal or Plastic Particle Shedding: Shedding of metal or plastic particles from the implant structure leads to inflammation, tissue damage, and bone dissolution.
- Osteolysis or Bone Death: Particle shedding may cause osteolysis, leading to bone death and dissolution, compromising the stability of the implant.
While some side effects are mild to moderate and resolve with treatment, others are severe or life-threatening. In cases of serious complications, knee revision surgery may be required to address the issues and improve the function of the knee joint.
