From the best knee replacement surgeon in Delhi NCR, total knee replacements are not one-size and style fits all. Considering prosthetic implants, they can greatly vary by material, design, and fixation. The knee implant can be fixed, mobile bearing, PCL retaining design, or PCL substituting style. Also, the three basic components of knee replacement implants are Femoral, Tibial, and Patellar.
The choice of implant is made by the surgeon based on several factors such as your age, lifestyle, physical situation, surgeon’s experience, and his/her level of trust and familiarity with the specific piece. The different types of total knee implants are as follows:
1. Fixed Bearing Implant
The most common type of knee replacement implant; it is called ‘fixed’ because the tibial component – polyethylene cushion – is firmly fixed to the metal platform base. The femoral component functions by rolling over this cushion. For most patients, the fixed-bearing prostheses offer a good range of motion and are usually just as long-lasting as other implants.
2. Mobile Bearing Implant
For individuals who are younger, more active, or overweight, your doctor might advise you to go for a rotating platform or mobile-bearing knee replacement. Designed to potentially offer longer performance with less wear, they are different from medial-pivot implants only in the case of the bearing surface. The patients can get greater rotation to the lateral and medial sides of their knees.
3. Medial Pivot Implant
These replicate the rotating, twisting, flexion, stability, and bending of your natural knee. So, it will feel more like your natural knees. However, when you compare them with fixed-bearing, mobile-bearing knee implants are less forgiving when it comes to an imbalance of soft tissues. Along with this, they can cost you a bit more than fixed-bearing implants.
4. PCL Implant – Retaining or Substituting
The PCL or Posterior Cruciate Ligament is a major ligament in the knee. It offers stability and support to the knee and prevents the femur back from rolling back on top of the tibia on flexing. Based on its condition, the type of knee implant – retaining or substituting is chosen.
