Biosteon is a synthetic calcium composite technology used in the manufacture of the Bioseon ACL Screw and the Biosteon Intraline Suture Anchor.

• Improved strength retention
• More than 20 years of proven clinical success
• Over 100,000 distributed 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 the longest clinical follow-up of all calcium-based composite materials now entering the market.1 All Biosteon products are distributed exclusively through Stryker®.

Biosteon® IntraLine® Suture Anchor

The Biosteon IntraLine Suture Anchor is intended for fixation of soft tissue to bone in orthopaedic procedures in the shoulder, foot/ankle, knee, hand/wrist, elbow and pelvis.
The device is supplied with either 2 or 3 polyethylene sutures with or without, stainless steel needles.

Frequently asked questions
What are Biosteon screws indicated for?

The Biosteon screw is indicated for use in Anterior Cruciate Ligament (ACL) reconstruction procedures where the surgeon: –

  • places the graft in the tibial and/or femoral tunnels; and
  • inserts screws between the tunnel wall and graft to hold the graft in place.

The Biosteon screw is used to provide interference fixation in patellar bone-tendon-bone grafts in ACL reconstruction.

The Biosteon screw is used to provide interference fixation during femoral and/or tibial fixation in ACL reconstruction using a soft tissue graft (semi-tendonosis-gracillis).

What are Biosteon screws contraindicated for?
  • The device should not be used where there is any known contraindication to arthroscopic repair.
  • The material is biodegradable, it should not be used where normal healing processes will not replace its function within its known duration.
  • The device should not be used in active infection or where there is any other contraindication to knee ligament repair or reconstruction.
  • The device should not be used in patients with any known allergy or reaction to plastic material.
