Sterile Cartilage Graft Plug Kit with Instrument Set
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current osteochondral allograft transplantation surgeries lack the precision and simplicity in selecting specifically sized allograft plugs and corresponding surgical tools, which can affect the accuracy and effectiveness of the procedure.
Innovation Solution
A sterile graft plug kit comprising grafts with diameters ranging from 5 to 15 mm and lengths of 12 mm, each with a cartilage layer thickness matching the existing cartilage, coupled with a bone portion featuring surface features to encourage bone growth, along with a set of instruments including a graft inserter, guidewire, and size gauge for precise implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a kit with specifically sized allograft plugs and corresponding surgical tools is used, then the accuracy and simplicity of osteochondral allograft transplantation surgeries is improved, but the device complexity increases
Solution Approach 1:
The surgical system is divided into discrete, pre-sized allograft plugs (e.g., 5mm, 7mm, 9mm, 11mm, 13mm, 15mm diameters) and corresponding instruments, allowing surgeons to select the appropriate size for each defect without complex customization. Each plug and instrument combination is independently packaged and sterilized as a separate unit.
Solution Approach 2:
The kit provides a universal solution for treating osteochondral defects of various sizes across different bone joints. The standardized plug sizes and corresponding instruments can be used across multiple surgical sites and patient populations, eliminating the need for custom-made implants for each case.
2Adaptability or versatility
If multiple specifically sized grafts are provided in the kit, then the adaptability to treat various bone joint locations is improved, but the quantity of substance increases
Solution Approach 1:
The allograft plugs are manufactured in discrete size variations (different diameters and lengths) to match common osteochondral defect dimensions. This parameter-based standardization allows the kit to cover a wide range of anatomical locations and defect sizes using a limited set of predefined dimensions, balancing versatility with inventory manageability.

AI summary
An apparatus and a method are provided for performing cartilage graft implant surgeries. The apparatus comprises a graft plug kit comprising one or more grafts configured to treat osteochondral defects in various bone joint locations in a patient's body. Each of the grafts comprises a cartilage layer coupled with a bone portion. The cartilage layer comprises a thickness selected to closely match the thickness of existing cartilage at an implant location. The bone portion comprises surface features configured to encourage the patient's bone tissue to grow into the bone portion, thereby accelerating incorporation of the graft into the patient's bone. An instrument kit comprises a multiplicity of instruments configured for implantation of the grafts into the patient's body, including at least a graft inserter, a guidewire, a reamer, and a size gauge.
