System and method for performing a surgical procedure using a drill guide and a robotic device operable in multiple modes. The drill guide is mechanically coupled to the robotic device. A pre-defined virtual trajectory constrains movement of the drill guide. In a first mode, a user is able to manually manipulate the drill guide while movement of the drill guide is constrained by the pre-defined virtual trajectory. In a second mode, the robotic device operates autonomously, for instance, to perform service on the robotic device.

A tissue protection sleeve for use in suprapatellar surgery is provided. The sleeve has a first end, a second end, an inner surface and an outer surface. The sleeve further comprises at least two open grooves that extend along the inner surface from the first end to the second end. The grooves are adapted to accommodate elongated fixation elements inserted into a tibia. A drill guide sleeve and a trocar for inserting a guide wire are also provided and can be accommodated by the tissue protection sleeve.

A patella impaction device includes a first clamp configured to be pressed along a pressure axis and onto a dome-shaped surface of a patella implant to be connected to a resected patella. The first clamp includes a shell-shaped clamping element mounted on a holding structure of the first clamp in a floating manner and allowing the clamping element to move at least along one axis of movement within a plane extending perpendicular to the pressure axis. The patella impaction device can be a component of a patella preparation set.

An orthopedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient.

A miniature bone mounted robot configured to perform minimally invasive orthopedic surgery coupled with regenerative three-dimensional bio-printing technology to restore cartilage and affected bone. The robot uses a sensor device attached to a holder affixed to the robot activated arm, to map the three-dimensional surface of the bone surface to be treated. The sensor may be a touch sensor, an optical imaging device, or another tool for mapping the bone surface. The robot shapes and prepares the bone surface and subsequently deposits a bio-ink implant in a three-dimensional pattern mimicking the original shape and depth of the articular cartilage. Because the entire procedure is conducted through the robotic platform rigidly mounted on the patients bone, there is no need for registration to preoperative three dimensional images, or for intraoperative tracking. Cell deposition based on mapping of the actual three dimensional anatomy, ensures an optimal outcome.

Disclosed is an innovation in the manner of surgically exposing the knee during total or partial knee arthroplasty, because currently, and as it has always been the case, the conventional surgical approach for the knee used the anterior route but also the medial route, where it was necessary to sever the whole tissue attachment of the inner bone border thereof, said tissue attachment comprising the capsule (envelope), the medial patellofemoral ligament and the tendon of the vastus medialis oblique (muscle) of the quadriceps. The present invention relates in particular to operating equipment intended to facilitate and/or implement a new and innovative surgical approach.

There is disclosed apparatus for effecting osteochondral restoration. In an embodiment, the apparatus includes a tube having a distal end, a proximal end and a lumen extending therebetween. A drill shaft is rotatably disposed in the lumen of the tube, the drill shaft comprising a distal end and a proximal end. At least one cutting blade is disposed at the distal end of the drill shaft. A coring housing extends from the distal end of the tube and disposed around the at least one cutting blade, the coring housing terminating in a distal cutting surface. Other embodiments are also disclosed.

A computer-implemented method of improving a patello-femoral response is described. A computing system characterizes an anterior geometry of a patella and determines a position of a posterior apex of the patella in relation to one or more features of the anterior geometry of the patella. The computing system further receives location information related to the patella as a knee joint is moved through a range of motion. The computing system provides one or more recommendations to improve a patello-femoral response.

A patella drill guide includes a head having a convexly curved outer surface. Cylindrical channels extend through the head. The drill guide also includes collar having an inner surface that defines a concavity corresponding in shape to the convexly curved outer surface. The inner surface of the collar is fitted to the outer surface of the head to define an articular joint.
