BioactIF OSTEOTRANS

Biodegradation redefined!

BioactIF OSTEOTRANS is the brand name of Richard Wolf's new generation of bioactive, bioabsorbable interference screws. The unique Osteotrans composite of poly-L-lactide (PLLA) and unsintered hydroxyapatite (uHA) has an osteoconductive effect: trabecular structures grow from the surrounding bone onto the implant surface within a short time.

The uniform uHA particles produced by a special manufacturing process form a permanent buffer for the lactic acid released as the PLLA component degrades, preventing inflammatory reactions in bone and tissue and encapsulation of the implant.

A special processing method gives the material mechanical properties comparable to the surrounding bone, ensuring that forces are transmitted from the surrounding bone to the implant. This is key to activating osteoblasts and allows complete bone remodeling in this area. The implant is easy to see on X-ray images.

Screw series at a glance

BK series
The new universal BK series has a deeper thread at the tip for excellent cutting and good insertion characteristics.
The size range has been extended and now offers implants in ideal lengths and diameters for all tibial and femoral fixation requirements in ACL and PCL reconstruction. The 6 mm version can also be used for other ligament replacements, such as medial patellofemoral ligament reconstruction.
- Deeper thread at the tip
- Conical tip
- Larger size range
OK series
The OK series is especially suitable for fixing BT and BTB grafts in primary and revision surgery. We recommend using a tap, as its blunt thread protects the graft.
- Graft-protecting thread
- The ideal solution for BT and BTB grafts
