An instrument for arthroscopic debridement of chondral lesions.
The new tool allows maintaining a vertical section of the shoulder of the chondral lesion anywhere in human joints using an arthroscopic approach.
Proper chondrectomy is critical prior to both bone marrow stimulation and implantation of matrices, as well as AMIC, MACI and other bioimplants.
Simply insert the chondrectome into the correct arthoscopic portal near the chondral defect.
The half-tube guide helps to insert the bioimplant into the joint cavity through the outer body layer. In addition, it provides pressure equalization during dry arthroscopy.
A plate wound retractor is used to expose the joint capsule including soft tissue, thus creating the necessary working space within the joint cavity during dry arthroscopy. Exposure is achieved by means of a thread pulled through the skin and connected to the plate wound retractor.
The curved raspatory is used to compress matrix or bone marrow at the site of the defect and finally to sculpt the surface.
The bone marrow guide (inserter) is used to implant bone marrow into the bone cyst or at the site of the defect. The tool enables compaction of the bone marrow during implantation. The bone marrow guide consists of a cylinder, a pusher and a loader.
Chondrectomes allow easy separation of the damaged and calcified cartilage layer from the subchondral surface, while leaving the subchondral plate intact. The unique shape of the chondrectomes and special formation of the cutting edge allow precise modeling of the cartilage lesions and formation of vertical walls on the defect.
The tools can be used in any anatomical situation (from any approach direction) and open or arthroscopically.
