TLS® (Tape locking screw) system

ST4 short graft method – All inside

TLS® is an ACL and PCL reconstruction system that uses a short graft.

Concept

Main principles of the TLS® system:

Graft:
– only one tendon harvested
– short closed loop configuration (4 tendon strands, ST4)
– pre-tensioned
– introduced arthroscopically into knee (all inside)
– press fit in the bone sockets
– 360-degree bone contact 

Bone tunnels:
– independent tunnel positioning using outside-in targeting method
– small diameter (4.5 mm)
– manual retrograde reaming of bone sockets for the graft
– sockets match size of each end of the graft

Fixation:
– suspension of ligament loop using anchoring tape
– TLS® fixation screws placed in the tape using outside-in method

Indications

The TLS® system is mainly indicated for:
– partial or complete ACL tears in adults
– PCL tears

Features

The TLS® instrumentation consists of:
– a work table used to prepare and pretension the graft (0–300 N)
– a universal aiming device used for outside-in placement of guide wires in the tibia and femur for ACL and PCL reconstruction
– a set of winged drills used for retroreaming of the bone sockets (7 to 11 mm)

The TLS® system consists of:
– a TLS® screw (ø10 mm, length 20 or 25 mm) made of titanium, PEEK or biocomposite material
