Nanofracture vs. Microfracture
-Deeper bone marrow access compared to shallower holes elicited
-Greater volume fill of the defect
-More hyaline character
-More type II collagen
-Less type I collagen
Chen et al. J Orthop Res. 2011
-Increased marrow access and bone remodeling correlated with improved cartilage resurfacing properties.
Chen et al. Am J Sports Med. 2011
-2mm deep Microfracture with an awl induced fracturing and bone compaction around holes that were
largely sealed off from adjacent bone marrow.
The Arthrosurface NanoFx instruments consist of a reusable hand instrument and a single use
disposable guide wire for performing a microfracture technique for the treatment of small localized
articular cartilage defect sites.
The HemiCAP® implants intraoperatively recreate the patients' articular cartilage surface convexities. This unique mapping technology enables the surgeon to place the implant so the implant becomes part of the patient's natural curvatures - both in the medial to lateral aspect as well as the anterior to posterior plane.
RegJoint™ is indicated for arthroplasties in small joints in hand and foot for patients suffering of rheumatoid arthritis or osteoarthritis. The specific target joints are metatarsal I-V, V (MTI I-V) in foot, carpometacarpal (CMC I) and metacarpophalangeal II-V (MCP II-V) joints in hand.
