Abstract
Implant apparatus and methods directed toward treating conditions involving the knee joint and the patella specifically are disclosed. Implants that maintain alignment or address misalignment of a patella through a full range of motion of the knee joint are disclosed.
Claims42
A method of treating patello-femoral osteoarthritis, comprising:
- assessing a tracking pattern of a patella throughout a full range of knee joint movement;
- implanting an implant so that a first end of the implant is attached to the patella and a second end of the implant is attached to bone or tissue surrounding the patella;
- and
- configuring the implant so that it corrects the tracking pattern of the patella.
A method of treating patello-femoral osteoarthritis with an implantable tensile member, comprising:
- attaching a first end of the tensile member to a patella or soft tissue surrounding the patella;
- attaching a second end of the tensile member to a femur or tibia;
- adjusting a tracking pattern of the patella along the femur by applying tension with the tensile member to shift load on the patella surfaces and relieve patella-femoral pain.
A system for treating patello-femoral osteoarthritis, comprising:
- a patella tracking correction implant, the patella tracking correction implant configured to apply a variable lateral force to the patella;
- and
- a patellar tendon implant, configured to be placed below a patellar tendon.
A patella shifting implant comprising:
- a first attachment for attaching a first end of the implant to the patella;
- a second attachment for attaching a second end of the implant to the femur;
- and
- a tensile member extending between the first attachment and the second attachment and configured to alter a tracking pattern of the patella.
A knee implant system for forming a connection between a patella and a femur, tibia or fibula comprising two knee anchors for anchoring to a patella and a femur and a structure for interconnecting said two knee anchors, wherein at least one of the knee anchors is a spring loaded anchor configured to be implanted entirely within the bone and to apply tension to the structure for interconnecting with an internal spring.
A method of treating patello-femoral osteoarthritis with an implantable tensioning implant, comprising:
- implanting a tensioning implant between the medial patella-femoral ligament;
- adjusting a tracking pattern of the patella medially by tensioning the medial patella-femoral ligament with the tensioning implant to shift load on the patella surfaces and relieve patella-femoral pain.
A knee implant system for forming a connection between a patella and a femur comprising two knee anchors for anchoring to the patella and femur and a flexible tension member interconnecting the two knee anchors.
