  • Patent number: 11369478
    Abstract: An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a posterior cam configured to contact a spine of the tibial bearing and a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the radius of curvature of the condyle surface may be increased during mid-flexion.

  • Publication number: 20220031476
    Abstract: A neck trial (170) is disclosed. The neck trial has a body (182) and a neck (186). The body has an exterior surface. The neck extends away from the body along a neck axis (190). At least one first line (194) is provided on the exterior surface, which extends in a first direction parallel to an inferior-superior axis of a patient when in use. At least one second line (196) is provided on the exterior surface, which extends in a second direction parallel to a medial-lateral axis of the patient in use. The number of first lines, or the position of the first line or lines relative to the second line or lines, is indicative of an amount of offset in the medial-lateral direction caused by the neck trial. The number of second lines, or the position of the second line or lines relative to the first line or lines, is indicative of an amount of leg-length in the inferior-superior direction caused by the neck trial. A kit of parts, a trial assembly and a method of trialling a joint of a patient are also disclosed.

  • Patent number: 11213397
    Abstract: A joint prosthesis system is suitable for cementless fixation. The system includes a metal implant component that has a mounting surface for supporting an insert. The metal implant component includes a solid metal portion and a porous metal portion. The porous metal portion has surfaces with different characteristics, such as roughness, to improve bone fixation, ease removal of the implant component in a revision surgery, reduce soft tissue irritation, improve the strength of a sintered bond between the solid and porous metal portions, or reduce or eliminate the possibility of blood traveling through the porous metal portion into the joint space. A method of making the joint prosthesis is also disclosed. The invention may also be applied to discrete porous metal implant components, such as augment.

  • Patent number: 11213301
    Abstract: The invention provides a reamer handle comprising: a shank having a distal tool coupling end adapted to releasably couple to a part of a surgical tool and a proximal end; a retractable catch which is linearly displaceable along the shank between a non-retracted position in which the catch captures the surgical tool within the distal tool coupling end of the tool holder and a retracted position in which the catch enables the tool to be released from the distal tool coupling end; a biasing member configured to bias the catch in the non-retracted position; and a sleeve extending along the shank. The sleeve comprises: a distally located catch contacting portion and a proximally located handle portion for manually displacing the sleeve relative to the shank such that displacement of the catch contacting portion moves the retractable catch between the non-retracted position and the retracted position to enable capture and release of the tool from the tool holder.
