Types and Benefits of Knee Replacement Implants

Orthopedists recommend knee replacement if the patient has to tolerate constant knee pain or if the patient’s daily activities are affected by reduced athletic performance. Patients have significantly less knee pain after undergoing minimally invasive knee replacement surgery.

Patients may be offered partial or complete knee arthroplasty, depending on their condition. The difference between the two depends on the patient’s condition and the level of pain.

What are the implants used in knee replacement?

Total knee osteoarthritis

During minimally invasive knee replacement, the orthopedist resurfaces the injured knee with an artificial part called an “implant.”

There are different types of implants. The type and design of implants used by orthopedists depends on many factors, including patient needs, knee problems and knee anatomy, age, weight, lifestyle, activity level, and overall health. .. ..

The orthopedist discusses the type of implant used for knee replacement with the patient and informs the patient about the benefits of using that particular implant.

What are the types of knee implants?

There are several different types of knee implants. The main difference between different types of knee implants is whether the implant replaces the entire joint or only part of the joint.

Different types of implants can be used for minimally invasive knee replacement. The optimal type of knee implant depends on factors such as ligament stability, bone and muscle condition, knee knock, and genu varum displacement. Below are the common types of implants that orthopedists use for knee replacement-

  • Unrestrained implant– In these types of implants, the top and bottom of the implant are not interconnected. For this type of implant to work, the medial and lateral ligaments of the knee need to be relatively stable to regulate knee movements such as bending, correction, and rotation. For most types of implants, the ACL (anterior cruciate ligament) is removed before the implant is placed.
  • Semi-restraint implant- This type of implant is used when the posterior cruciate ligament is not stable enough and needs to be removed. In this type of implant, the two components are connected using a hinge type to provide stability.
  • Restrained implant– In this type of implant, two components, the upper limb and the lower leg, are hinged together and attached to both bones using a long stem. Restrained implants can be used if both the medial and lateral ligaments are not stable enough. Other reasons doctors may suggest this type of implant include poor bone condition and severe displacement such as knee knocks and genu varum.

It’s best to talk to your orthopedist about which type of implant is right for you and the strengths and weaknesses they have.

Cement and Cementless Knee Replacement

Cement implants have traditionally been used. Advances in implant technology have resulted in non-cemented knee implants that do not need to be cemented. For non-cemented knee implants, the textured surface of the knee implant promotes bone growth. Therefore, the implant is firmly fixed to the bone. Both total and non-total knee arthroplasty can be used, depending on the needs of the patient.

  • Cement implant- Cemented knee osteoarthritis implants are fixed in place with quick-drying bone cement that binds the patient’s natural bone to the implant.
  • Implants that are not cemented- Also popular as press-fit knee implants, non-cemented knee implants have a rough, porous surface that promotes new bone growth. Currently, cementless knee implants are only used for total knee osteoarthritis. The majority of knee implants used in knee replacement are non-cemented implants.
