Biosteon is a synthetic calcium composite technology used for interference screws in the reconstruction of anterior and posterior ligaments and suture anchors for rotator cuff repairs.

  • Improved strength retention
  • 16 years of proven clinical success
  • Over 100,000 implanted worldwide

Biosteon was introduced in 2001 and produced through a proprietary moulding technology, which delivers a suspension of osteoconductive particles of calcium hydroxyapatite in a poly-L-lactic acid (PLLA) matrix – to improve strength retention, bone-bonding potential and pH buffering in the graft healing period. Biosteon has 16 years' proven clinical success and has been implanted in over 100,000 patients worldwide.


The Biosteon Screw features a unique thread form for easy insertion and offers increased pull-out strength compared with similar devices in the market.

The Biosteon Cross Pin is for femoral fixation of soft-tissue (hamstring) grafts.


Biosteon has the longest clinical follow-up of all calcium-based composite materials now entering the market.2 All Biosteon products are distributed exclusively through Stryker.

Sports injuries

Arthroscopic procedures and the use of absorbable implants are common for treating sports injuries, as they provide a secure graft fixation while allowing biocompatible absorption and eventual replacement by bone.
