Patient-specific knee alignment guide and associated method
A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.
Tibial alignment device and unit thereof
A tibial alignment device includes an upper part for coupling with a tibial cutting guide and a lower part coupled to the upper part to be vertically slidable, wherein the upper part includes a cutting guide coupling part configured to mount the tibial cutting guide, and a connection part to connect the upper part and the lower part, and the lower part includes an ankle forceps part, wherein the cutting guide coupling part includes a fastening member for coupling to the tibial cutting guide, and a reception member to slidably receive the fastening member, wherein the fastening member includes a coupling part that protrudes to be coupled to the tibial cutting guide, the reception member includes a coupling part that protrudes to be coupled to the tibial cutting guide, and the coupling part of the fastening member is capable of adjusting a gap with respect to the coupling part of the reception member.
Tibial cutting guide assemblies and associated instrumentation for performing surgical methods
This disclosure is directed to tibial cutting guide assemblies for preparing a tibia for receiving an arthroplasty implant. Exemplary tibial cutting guide assemblies may include a tibial cutting block for making precise cuts in the tibia, and a slope setting pin for establishing a patient specific tibial slope. The tibial cutting guide assemblies allow for level resection while providing surgical control over internal/external rotation and varus/valgus alignment.
Customized patient-specific orthopaedic surgical instruments
An orthopaedic surgical instrument is provided having a first customized patient-specific surgical instrument and a second customized patient-specific surgical instrument configured to be removably coupled to the first customized patient-specific surgical instrument. The second customized patient-specific surgical instrument includes a body positioned in a gap defined between posteriorly-extending arms of the first customized patient-specific surgical instrument.
System and method for transporting suture
A suture transport system is disclosure for placing a flexible member along a tunnel, the system including a means of transporting a flexible member along a tunnel from a first opening in the tunnel through to a second opening at an opposite end of the tunnel, such that the flexible member extends from both the first and second opening. The system also includes a means of capturing a portion of the flexible member at the second opening, to inhibit the flexible member from retracting into the tunnel second opening. The means of capturing includes an aperture for capturing the portion of the flexible member.
UNICOMPARTMENTAL CUSTOMIZED ARTHROPLASTY CUTTING JIGS
Disclosed herein are unicompartmental femoral and tibial arthroplasty jigs for respectively assisting in the performance of unicompartmental femoral and tibial arthroplasty procedures on femoral and tibial arthroplasty target regions. The jigs each include a mating surface. The mating surface of the femoral jig is configured to matingly receive and contact a generally planar area of an anterior side of a femoral shaft generally proximal of the patellar facet border and generally distal an articularis genu. The mating surface of the tibial jig is configured to matingly receive and contact a generally planar area of an anterior side of a tibial shaft distal of the tibial plateau edge and generally proximal of the tibial tuberosity.
KINETIC ASSESSMENT AND ALIGNMENT OF THE MUSCULAR-SKELETAL SYSTEM AND METHOD THEREFOR
A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load, and joint alignment. The system further includes a remote system for receiving, processing, and displaying quantitative measurements from the sensors. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation. The kinetic assessment increases both performance and reliability of the installed joint by reducing error that is introduced by elements that load or modify the joint dynamics not taken into account by prior assessment methods.
PATIENT-SPECIFIC KNEE ALIGNMENT GUIDE AND ASSOCIATED METHOD
A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.
Anchor apparatus
An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.
Alignment devices and methods
Embodiments of the invention include devices and methods for implanting arthroplasty devices. Some embodiments include designs that allow for use of x-ray images as the only images used to fully and accurately preoperatively and intraoperatively size and align arthroplasty device components and prepare all necessary tissue.
