Publication number: 20230108048Abstract: A system 100 or designing a surgical kit 700 for articulating surface repair in an anatomical joint of a patient is provided, which comprises at least one processor 120 configured to: determine damage to the anatomical joint; select, from a predefined set of implants having varying dimensions, the implant 300 that is the best fit for repairing the determined damage; select, from a predefined set of insert tools, the insert tool 720 corresponding to the selected implant 300; and design a contact surface 540 of a guide tool 500 to have a shape and contour that is designed to correspond to and to fit the contour of a predetermined area. This enables the use of standardized implants 300 that can be manufactured batch-wise, while still using an individualized guide tool 500 to ensure correct positioning of the implant 300. This helps ensuring that the implant will be positioned in the exact location of the determined damage.Type: ApplicationFiled: September 26, 2022Publication date: April 6, 2023Applicant: Episurf IP-Management ABInventors: Katarina FLODSTRÖM, Leif RYD

Publication number: 20230096683Abstract: In accordance with one or more embodiments herein, a patellofemoral implant arrangement 200 for repairing damage in a patellofemoral articulation of a patient is provided. The patellofemoral implant arrangement 200 comprises a femoral trochlear implant 250, comprising an articulating surface 255, and a patellar implant 300, configured to be inserted, preferably with press-fit, into a recess 620 in a patella 600 in such a way that the perimeter of an articulating surface 310 of the patellar implant 300 does not extend beyond a surrounding articulating surface of the patella 600. The articulating surfaces 255, 310 of the femoral trochlear implant 250 and the patellar implant 300 are designed to allow that they at least partly interact with each other when the implants 250, 300 are implanted into the knee joint and the patella 600 lies in the intercondylar groove of the femur.Type: ApplicationFiled: September 27, 2021Publication date: March 30, 2023Applicant: EPISURF IP-MANAGEMENT ABInventors: Johan JULIN, Ingrid BRATT, Katarina FLODSTRÖM, Leif RYD
