Abstract
A method for replacing a natural articular surface on a bone may include movably mating a first adjustable attachment feature of an arthroplasty prosthesis with a second adjustable attachment feature of a bone anchoring component to movably couple the bone anchoring component to a bone-facing side of the arthroplasty prosthesis, securing a bone engagement surface of the bone anchoring component to a resected surface of the bone, and replacing the natural articular surface on the bone with an articular surface on a joint-facing side of the of the arthroplasty prosthesis.
Claims25
A method for replacing a natural articular surface on a bone comprising:
- movably mating a first adjustable attachment feature of an arthroplasty prosthesis with a second adjustable attachment feature of a bone anchoring component to movably couple the bone anchoring component to a bone-facing side of the arthroplasty prosthesis;
- securing a bone engagement surface of the bone anchoring component to a resected surface of the bone;
- and
- replacing the natural articular surface on the bone with an articular surface on a joint-facing side of the of the arthroplasty prosthesis.
A method for replacing a natural articular surface on a bone of a knee joint comprising:
- mating a prosthesis attachment feature of a knee arthroplasty prosthesis with one of a primary attachment feature of a primary bone anchoring component and a revision attachment feature of a revision bone anchoring component to removably couple one of the primary bone anchoring component and the revision bone anchoring component to a bone-facing side of the knee arthroplasty prosthesis;
- securing one of a primary bone engagement surface of the primary bone anchoring component and a revision bone engagement surface of the revision bone anchoring component to a resected surface of the bone;
- and
- replacing the natural articular surface on the bone with an articular surface on a joint-facing side of the of the knee arthroplasty prosthesis,
- wherein:
- at least a majority of the primary bone anchoring component is located outside an intramedullary canal of the bone when the primary bone anchoring component is secured to the bone;
- and
- a distal portion of a stem of the revision bone anchoring component is securable within the intramedullary canal of the bone when the revision bone anchoring component is secured to the bone.
A method for replacing a natural articular surface on a bone of a knee joint comprising:
- selecting either of:
- a primary bone anchoring component comprising:
- a primary bone engagement surface securable to a resected surface of the bone;
- and
- a primary attachment feature;
- and
- a revision bone anchoring component comprising:
- a revision bone engagement surface securable to the resected surface of the bone;
- and
- a revision attachment feature;
- rotatably and/or translatably mating a prosthesis attachment feature of a knee arthroplasty prosthesis with either of the primary attachment feature and the revision attachment feature to couple either of the primary bone anchoring component and the revision bone anchoring component to a bone-facing side of the knee arthroplasty prosthesis;
- securing either of the primary bone engagement surface and the revision bone engagement surface to the resected surface of the bone;
- and
- replacing the natural articular surface on the bone with an articular surface on a joint-facing side of the of the knee arthroplasty prosthesis.
A method for replacing a natural articular surface on a bone comprising:
- removably mating a prosthesis attachment feature of an arthroplasty prosthesis with a component attachment feature of a bone anchoring component to removably couple the bone anchoring component to a bone-facing side of the arthroplasty prosthesis;
- securing a bone engagement surface of the bone anchoring component to a resected surface of the bone;
- and
- replacing the natural articular surface on the bone with an articular surface on a joint-facing side of the of the arthroplasty prosthesis,
- wherein the prosthesis attachment feature comprises a circular shape having a diameter of at least 10 mm.
