Knee Replacement Types, Risk Factors, and Diagnosis

Knee replacement infection is a condition that a person gets after the related surgery. Replacement in our hinge joint helps doctors to remove pain, stiffness, apparent instability, or functionality losses affecting our daily lives and activities.

In a healthy joint, your thigh-ends and shin bones are covered with hard cartilage. These cartilages allow such limb bones to move against each other as needed. Diseases like arthritis damage these tissues and thus they become thinner. Thin cartilages are easy victims of casualties.

In the operative procedure, surgeons remove these weakened cartilages and substitute those with metal or plastic hard nuts. Plastic acts like hard cartilages thus restoring the movement capacity of our body joints.

Procedure Types

Total Knee Replacement

It involves joint surface transmutation at the thigh bone end. Doctors remove the joint surface at your shin bone top too.

Besides those, this procedure may involve substituting the kneecap under-surface with a smooth plastic dome. Though such a decision is taken on the surgery table, most surgeons prefer to preserve our natural patella.

Unicompartmental partial knee replacement

In cases where a unitary side is affected by the conjuncture disease, doctors decide to adopt the partial substitution process. In the majority of cases, the central knee-side is affected. A partial replacement procedure means less interference with the organ than what we have experienced with the total procedure, better post-procedure functionality, and quicker recovery can be assured.

Kneecap replacement

The process includes knee-cap under-surface replacement; its groove is also transferred in such a process. Such operative procedure is feasible if arthritis did affect only your kneecap undersurface and the trochlea.

Its success rate is much low than the total knee replacement procedure.

Revision replacement

Doctors consider such processes for the following reasons:

  • Major deformity caused in the hinge joint.
  • Remarkable bone is lost due to accidents of arthritis.
  • Ligament weakness in the main organ.

Risks involved

Surgery processes are hassle-free in the majority of cases though about 5% of surgery cases have undergone complications. Hopefully, most of such complications are easily treatable.

Risks depend on the patient’s age and his/her overall health situation. Older people are more prone to such risks.

Risks with knee replacement surgeries may include:

  • Pain due to blood clotting in the leg's deep veins. It happens due to changes in the blood-flow direction as well as its ability to coagulate. Doctors apply pumps and other special stocking methods to reduce such risks.
  • Bleeding risk enhances as surgeons use blood-thinning drugs to avoid blood coating.
  • In rare cases, clotted blood may travel to our lungs. It may cause breathlessness and chest pain. If not cared for in due time, it may result in fatality.
  • Infection that is cured with antibiotics.
  • Nerve damage including tissue injury.
  • Pain.
  • Dislocation.
  • A bone fracture may occur after a few months post-operation.


Patients are invited to a pre-admission clinic a few weeks before surgery. The pathologist team ensures that you are running with their standard health standard. It is absolutely required for the process and other associative functionalities.

Diagnostic tests would comprise:

  • Blood test for anemia test-out. It helps to assure that your renal organs are functioning properly.
  • An MRSA swab test will help check that you do not carry the process-resisting bacteria.
  • Urine tests are conducted to assess your probability of having an infection and calculating its way out.
  • Surgeons will also order an electrocardiograph tracing test. This ensures that the patient’s heart is functioning properly.

My verdict

Patients are the final deciders about the treatment policy to be applied. You are always free to ask about the benefits that you are going to get from the procedure. Surgeons, anesthetists, nurses, and various other paramedical staff are answerable to you. Inform them about your medicine allergies and confirm the substitutions.
