A knee joint replacement surgery is mainly divided into a Total Knee Replacement and a Partial Knee Replacement.

A Simple Way To Understand Knee Replacement

The knee joint complex is made up proximally of femoral condyls, distally of the tibial plateau and the posterior aspect of the patella or the knee cap. A TKR and a PKR are pretty common operations done in today’s world because of the occurrence of arthritis being so common. Rheumatoid arthritis may affect people of all ages but osteoarthritis usually affects women who have crossed the 4th decade of their lives. Here is a simple explanation to help you out with the surgical procedure –

  • Total Knee Replacement – With the help of an x ray, the doctors figure out which area of the femur, tibia and patella are damaged the most. During surgery, they will be shaping up those areas so that the affected areas of scrapped off and the metal implants can be inserted instead of them. In a TKR, the osteoarthritis of the knee is wide spread and the patient is under a lot of pain. A prosthesis inserted is usually platinum or titanium depending on the patient. After the surgery is over, the patients have reported 90% improvement in their mobility and functioning and they feel almost no pain. Of course, the operation will be followed by months of physical therapy where the patient will be able to increase the mobility and strength of the surrounding muscles.
  • Partial Knee Replacement – A PKR is the milder form of knee replacement surgery. Among the types of knee replacement surgeries, a PKR will have less recovery time and the hospital stay will also be shorter. Patients who suffer from arthritis only in one portion of the knee are generally prescribed a PKR but the probability of the arthritis returning or affecting the other compartments of the knee is significantly high in a PKR. It is important that in a PKR, the patient is made aware of the further complications or the relapse of the condition and that is the reason why only 10% of patients with arthritis are prescribed the PKR instead of the TKR.

Even if there is a slightest hint of osteoarthritis, the patient is supposed to make an appointment with the orthopedic doctor and should be started on treatment for the condition. If only all else fails, the patient should be asked to undergo a knee replacement surgery. It is always better to stick to simple treatments in the form of medications or physical therapy at first. If the condition doesn’t get better even then, it can be concluded that the patient has no option other than to opt for a surgical procedure for the knee.
