Infinity-LockTM 5mm Tape MCL

Reconstruction of knee medial collateral ligament (MCL) with Infinity-Lock 5mm Tape

Medial Collateral Ligament (MCL) Repair with Infinity-Lock™

In many knee injuries that appear to involve only the ACL, the medial collateral ligament (MCL) is also affected. If left undiagnosed or untreated, an MCL injury can significantly impact patient outcomes.

Research shows that the medial complex is injured in over half of cases initially thought to be isolated ACL injuries (with recent studies reporting rates as high as 67%¹). Furthermore, studies demonstrate that the risk of ACL revision surgery is lower when associated MCL injuries are treated surgically rather than managed non-surgically.

The Infinity-Lock™ tape provides an effective solution for MCL repair. By reinforcing the ligament, it enhances knee stability, supports a faster return to daily activities and sports, and preserves the hamstring tendons for potential use in ACL or other graft procedures.

Results

A 2023 published review using this technique1 on 85 cases with average 4.8-year follow-up reported:

  • Improved knee function: median Kujala score 82 (pre-op 40)
  • No re-dislocation
  • No patella fracture
  • No knee stiffness

Minor complications were minimal, affecting only 10.6% of cases and included issues such as medial knee pain, residual instability, or superficial infection.

Stability without graft harvesting

Improved patient outcomes – Repair of the MCL with Infinity-Lock 5mm Tape allows reduced pain, improved function and rapid rehabilitation, enabling successful return to everyday activities and sport.

The open weave structure of Poly-Tapes and Infinity-Lock Tapes allows a natural body response whereby native tissue integrates into the device.
Rotational stability – Repair methods with the Infinity-Lock 5mm Tape can include repair of the deep insertion as well as superficial insertion. This technique provides rotational stability to the knee. Reports show variations of the techniques.
Flexible –

  • Can be used alongside repair of the native ligament or with a graft.
  • The open-weave tape can be sutured to the native ligament or graft to provide closer protection if desired.
  • Repair with the tape alone removes the morbidity associated with harvesting an autograft.

The unique design of the tape combines corded ends to assist in handling and passing through tunnels with an open-weave flat central tape for tissue incorporation. The implant is constructed of multifilament high tenacity polyester (polyethylene terephthalate) fibre providing a soft flexible structure with high strength.

Case Study 2

How it works

Stand-alone (no graft)

 

Step 1.
Carry out any repair of the native ligament first.

Step 2.
Undo the preformed loop on the Infinity-Lock 5mm tape.

Step 3.
Fix one end of the tape at the superficial (distal) insertion with an interference screw. A staple can be used instead, if there is a risk of clashing bone tunnels.

Step 4.
Drill a tunnel at the origin of the MCL, at the femoral medial epicondyle. Pass the corded tape end through the tunnel.

Step 5.
Tension the tape with the knee flexed at 30 degrees and neutral rotation and fix with an interference screw.

Step 6.
Suturing the Infinity-Lock 5 mm tape to the native MCL along the entire construct may be done for reinforcement.

 

Combined with graft as a brace line

 

Step 1.
Fix both the graft and tape in parallel in the tibial and femoral tunnels described above.

Step 2.
An all-suture anchor may be placed 1 cm distal to the joint line and the limbs passed through the graft and the Infinity-Lock tape and tied to recreate the deep MCL insertion site.

Step 3.
Suture of the Infinity-Lock 5 mm tape to the graft using Vicryl suture along the entire construct may be done for reinforcement.

Product Information

Indications

Infinity-Lock Tapes are indicated for patients requiring soft tissue approximation and reconstruction of ligaments and tendons.

These are single use devices intended to be used for tissue approximation in orthopaedic procedures, including use in reconstructing damaged or torn ligaments or tendons according to the surgeon’s own preferred technique and at his/her discretion.

Poly-Tape 30mm Quads

Extensor Mechanism Tendon Reconstruction with Poly-Tape An extensor mechanism tendon rupture is a debilitating, though relatively uncommon, injury that requires prompt treatment. Reconstruction with Poly-Tape provides a straightforward, “off-the-shelf” solution that enables early mobilisation and supports faster rehabilitation. Well-established in clinical practice, this technique is backed by multiple published studies, all demonstrating excellent functional outcomes and reliable recovery. Established clinical history Studies have been published since 2008 treating a total of 88 knees for either patellar tendon or quadriceps tendon rupture with good functional outcomes. The earliest study used 20 mm tape, currently 30 mm tape is used. A Clinical Summary is available. • Good function restored across all studies (different scoring systems used) • Low levels of extensor lag and good range of motion • Low complication rates – re-rupture rate lower than reported in state-of-the-art literature Designed for success Simple Solution Straightforward technique for occasional need Long shelf-life synthetic tapes can be held in stock for prompt use None of the risks or availability problems of allograft No donor site morbidity as encountered with autograft For Reliable Results Provides excellent intrinsic strength and allows early mobilization Broad, stiff tape to reduce stretch in the repair – a risk factor for extensor lag Permanent implant – leave in place.

Infinity-LockTM 5mm Tape MPFL

MPFL Reconstruction with Infinity-Lock™ Reconstruction of the medial patellofemoral ligament (MPFL) using Infinity-Lock™ tape stabilizes the patella, helping to reduce knee pain and shorten recovery time. This advanced technique avoids drilling a tunnel through the patella. Instead, the 5mm broad Infinity-Lock™ tape provides a strong double-bundle structure without the need for autograft or allograft tissue. The result is a safer, less invasive procedure that enables rapid rehabilitation, allowing patients to regain mobility and return to daily activities sooner. Results A 2023 published review using this technique1 on 85 cases with average 4.8-year follow-up reported: Improved knee function: median Kujala score 82 (pre-op 40) No re-dislocation No patella fracture No knee stiffness Minor complications were minimal, affecting only 10.6% of cases and included issues such as medial knee pain, residual instability, or superficial infection. Stable, safe solution to MPFL laxity Reduce risk of patella fracture – The technique secures the tape to the medial border of the patella with all-suture anchors at two points on the patella. With this method there is no tunnel though the patella, this reduces the risk of damage to the patella. No need for autograft or allograft – By using synthetic tape to reconstruct the MPFL, there is no need to harvest any autologous tissue, so the patient’s hamstrings (for example) are preserved. Similarly, the method avoids the need for an allograft, with its additional cost and variable strength and stiffness. Versatile design – The implant incorporates unique features to combine strength, ease of handling, low-profile and long-term issue incorporation. The design innovation and consistent properties ensure that it can withstand the rigours of knee joint function while minimising any potential adverse reactions in the patient. Improve patient outcomes – Patients undergoing MPFL reconstruction with the Infinity-Lock Tape have improved joint stability, decreased pain and faster recovery times. The article is available here.
