The BioLok® Screw is used to provide interference fixation of patellar bone-tendon-bone grafts in ACL reconstruction. The BioLok® Screw is used to provide interference fixation during femoral and/or tibial fixation in ACL reconstruction using a soft tissue graft (semi-tendonosis gracilis). ## Device Story BioLok® Screw is a cannulated, sterile, single-use bone fixation screw; composed of absorbable polymer mixture of Tri-Calcium Phosphate (TCP) and poly (L-lactide) (PLLA). Used by surgeons in ACL reconstruction procedures; device inserted between tunnel wall and graft to provide interference fixation for patellar bone-tendon-bone or soft tissue grafts. Material gradually absorbs into body over time. Provides early and sustained graft fixation strength. ## Clinical Evidence Bench testing only. Pull-out test results demonstrate strength comparable to predicate devices, confirming ability to provide early and sustained graft fixation. ## Technological Characteristics Cannulated bone screw; material: composite of Tri-Calcium Phosphate (TCP) and poly (L-lactide) (PLLA); absorbable polymer; sterile; single-use. ## Regulatory Identification A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system. ## Predicate Devices - Bio Interference Screw (Arthrex) - BioScrew (Linvatec) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The BioLok® Screw is manufactured from a mixture of Tri-Calcium Phosphate (TCP and poly (L-lactide) (PLLA). #### (ર) Subject device intended use: The BioLok® Screw is indicated for use in anterior cruciate ligament (ACL) reconstruction procedures where the surgeon: - places the graft in tibial and/or femoral tunnels; and . - inserts screws between the tunnel wall and graft to hold the graft in place. . The BioLok® Screw is used to provide interference fixation of patellar bone-tendon-bone grafts in ACL reconstruction. The BioLok® Screw is used to provide interference fixation during femoral and/or tibial fixation in ACL reconstruction using a soft tissue graft (semi-tendonosis gracilis). #### Technological characteristics: (6) The BioLok® Screw has the same technological characteristics (i.e., design and material) when compared to the predicate devices. #### (7) Performance data: Test results confirm that this composite has the requisite strength over time to provide early and sustained fixation of the graft. Pull out test results compare favorably with the predicate devices. #### Basis for substantial equivalence: (8) The BioLok® Screw is equivalent in design, materials and indications to the predicate devices. {1}------------------------------------------------ Image /page/1/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services.

Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 # APR 2 6 2000 Ms. Debbie De Los Santos Regulatory/Clinical Specialist Encore Medical Corporation 9800 Metric Boulevard Austin, Texas 78758 Re: K993630 Trade Name: BioLok® Screw Regulatory Class: II Product Code: HWC Dated: February 4, 2000 Received: February 7, 2000 Dear Ms. Los Santos: We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general control provisions of the Act. The general control provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. {2}------------------------------------------------ Page 2 - Ms. Debbie De Los Santos If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4659.
