Unicompartmental knee prosthesis

Unicompartmental knee prostheses are classified into mobile-bearing unicompartmental knee prostheses and fixed-bearing unicompartmental knee prostheses. Both types consist of a femoral condyle, a tibial tray, and a tibial insert.

Scope of Application

It is used with bone cement and indicated for unicompartmental knee replacement.

Product Features

★XK Unicompartmental Knee Prosthesis (Mobile Bearing)

1.Femoral condyle:

(1)Spherical articular surface with a single radius: Ensures minimal contact stress during omnidirectional movement, with no edge stress.

(2)Dual-post design: Enhances prosthetic rotational stability and reduces the risk of prosthetic loosening.

(3)High-tolerance design: Allows for a safe range of 10° of varus and valgus alignment.

2.Tibial plateau support:

(1)Highly polished design of the articular surface and edges of the tibial tray: Minimizes wear of the tibial insert and reduces irritation and damage to the surrounding soft tissues.

(2)Porous design of the tibial tray flange: Facilitates uniform distribution of bone cement and enhances the stability of the prosthesis after implantation.

3.Tibial plateau padding:

(1)True spherical articular surface design: Matches one-to-one with the femoral condyle of the corresponding model, achieving uniform distribution of stress on the femoral side.

(2)Unconstrained design of the tibial insert: Ensures full consistency with the femoral condyle during omnidirectional movement, maximizing the conformity of the entire articular surface at different movement angles.

★ XG Unicompartmental Knee Prosthesis (Fixed Bearing)

1.Femoral condyle:

(1)15° included angle design between the posterior condylar plane and dual posts: Enhances prosthetic stability after implantation.

(2)Anatomical design: Maximally replicates and restores the natural physiological structure of the knee joint.

(3)Multi-radius design of the articular surface: Ensures smoother and more stable joint movement.

(4)Posterior extension design of the femoral posterior condyles: Provides stable flexion up to 155°.

(5)Unconstrained design: Allows for a safe range of 8° of varus and valgus alignment.

2.Tibial plateau support:

(1)Dual-post + fin bionic design: Effectively prevents transverse and longitudinal displacement of the tibial tray, reducing the risk of postoperative tibial tray loosening.

(2)Anatomical design: Maximally replicates and restores the natural physiological structure of the knee joint.

3.Tibial plateau pad:

(1)Precise and stable locking design: Reduces micromotion after implantation.

(2)Thickness adjustable in 1mm increments: Delivers optimal ligament tension.

Product Advantages

• Designed based on the skeletal data of the Chinese population, it achieves superior bone coverage and offers a more comprehensive range of models and specifications to better meet clinical requirements.
