★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.
