Abstract
A prosthetic assembly is provided. The prosthetic assembly comprises: a tibial tray having a medial retaining bracket, a lateral retaining bracket and a substantially centrally disposed boss, a medial bearing, a lateral bearing and a retention clip having a pair or arms which engage opposite sides of the boss and trap the medial lateral bearings, against the medial and lateral retaining brackets, respectively. A method of securing bearing components to a prosthetic assembly is also provided.
Claims16
A prosthetic assembly comprising:
- a tibial tray having a medial retaining bracket positioned at a medial edge of a medial portion of the tibial tray, a lateral retaining bracket positioned at a lateral edge of a lateral portion of the tibial tray, and a substantially centrally disposed boss;
- a medial bearing;
- a lateral bearing;
- and
- a retention clip having a first arm and a second arm each extending anteriorly-to-posteriorly to engage opposite sides of the boss, the first arm to engage and trap the medial bearing against the medial retaining bracket and the second arm to engage and trap the lateral bearing against the lateral retaining bracket.
A prosthetic assembly comprising:
- a tibial tray comprising:
- a medial retaining bracket positioned along a medial periphery of the tibial tray;
- a lateral retaining bracket positioned along a lateral periphery of the tibial tray;
- and
- a boss positioned at a posterior side of the tibial tray;
- a medial bearing securable to the medial retaining bracket;
- a lateral bearing securable to the lateral retaining bracket;
- and
- a retention clip including a medial arm and a lateral arm engageable with opposite sides of the boss and, the medial arm engageable with the medial bearing to trap the medial bearing against the medial retaining bracket and the lateral arm engageabie with the lateral bearing to trap the lateral bearing against the lateral retaining bracket.
A prosthetic assembly comprising:
- a tibial tray having a medial retaining bracket positioned at a medial edge of a medial portion of the tibial tray, a lateral retaining bracket positioned at a lateral edge of a lateral portion of the tibial tray, a tibial stem comprising a recess, a resilient element provided within the recess, and a substantially centrally disposed boss,
- a medial bearing;
- a lateral bearing;
- and
- a retention clip having a pair of arms which engage opposite sides of the boss and trap the medial bearing and the lateral bearing against the medial retaining bracket and the lateral retaining bracket, respectively;
- wherein the resilient element is configured to apply tension to an artificial ligament of the prosthetic assembly, and wherein the retention clip is configured to cover the recess of the tibial stem such that the resilient element is retained within the recess by the retention clip.
