Xiros™
Synthetic Ligaments
Xiros designs and manufactures innovative implantable medical devices for sports medicine and orthopaedic surgery.
Established in Leeds, United Kingdom, in 1982, Xiros has almost four decades of experience developing textile-based
implants and surgical solutions for ligament and tendon repair, reconstruction and reinforcement.
Combining specialist textile engineering with clinical collaboration, Xiros develops solutions designed to support surgeons
across a range of upper- and lower-limb procedures.
Advanced implantable textile technology
Xiros implants are manufactured from medical-grade polyethylene terephthalate, commonly known as polyester—a non-
absorbable material with an established history of use in implantable medical devices.
Through careful textile design, polyester implants can be engineered to provide mechanical properties suited to ligament
and tendon applications. Many Xiros implants feature an open woven structure designed to act as a scaffold for bone and
soft-tissue ingrowth. Selected products also undergo a proprietary gas-plasma surface treatment that changes the
polyester surface from hydrophobic to hydrophilic, supporting cell recruitment and attachment to the implant.
Supporting a range of orthopaedic procedures.
Xiros also offers a range of Poly-Tapes and Infinity-Lock™ Tapes for soft-tissue approximation and ligament or tendon
reconstruction applications.
Designed with surgeons. Focused on patients.
From product development and biomechanical testing to surgeon education and procedural support, Xiros works closely
with healthcare professionals to translate clinical needs into practical surgical solutions.
The company’s goal is to improve patients’ quality of life through innovative medical devices supported by specialist
manufacturing, clinical evidence and surgeon training.

MCL
The medial collateral ligament (MCL) is
affected in many knee injuries that appear to
involve only the ACL. If the MCL injury is not
recognised, the patient’s outcome is affected.
The medial complex is injured in more than half of apparently isolated ACL injuries (67% recently reported1). Studies have shown that the risk of revision of ACL treatment is lower where the MCL injury was treated surgically compared to non- surgically2,3. Repairing the MCL with the Infinity- Lock tape helps to stabilise the knee assisting the return to activities and sport. It also spares the hamstring tendons for possible graft use in the ACL or other structure.
Surgical Technique
Features and Benefits
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.

MPFL
Reconstruction of the MPFL ligament with
Infinity-Lock Tape to stabilise the patella
shortens recovery time and reduces knee pain
The technique does not require a tunnel through the patella. The repair with Infinity-Lock 5mm broad tape provides a double-bundle structure and avoids the need for autograft or allograft. This allows rapid rehabilitation, helping patients to regain mobility and get back to their daily activities sooner.
Surgical Technique
Features and Benefits
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.
Data
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
and included issues such as medial knee pain, residual instability,
or superficial infection.

Upper Limb
AC Joint
Successful operative treatment of the acromioclavicular joint (ACJ) requires a meticulous technique.
Meta-analysis has found that using a loop around the coracoid, as opposed to drilling through the bone, results in a lower incidence of re-operation as well as fewer failures in chronic injuries1. The Infinity-Lock Button system provides good clinical and radiological outcomes in treating acromioclavicular joint separation, with its broad tape looping around the coracoid and passing through the clavicle vertically with low-profile fixation.
Surgical Technique
Features and Benefits
Protecting tissue
Infinity-Lock Button System is designed to enable meticulous care of the tissue structures in the shoulder.
- No drill hole through the delicate coracoid, reducing risk of fracture
- Instrumentation: CC-Hook dedicated coracoid passer for minimal soft-tissue damage
- Broad tape for reduced likelihood of bone abrasion
- 4 mm clavicle vertical tunnel, no A-P drilling
Tissue in-growth
The tape construct has an open-weave structure, facilitating tissue in-growth and on-growth. Tissue graft augmentation can be used but is not needed, eliminating autograft morbidity and allograft cost issues.
Efficient solution
The one-size-fits-all design and single-use instrument reduce inventory and instrument-kit complexity as well as eliminating the risk of mis-sizing.
Performance
- Studies show good clinical and radiological outcomes
- Pain reduction, anatomic shoulder reduction and enabling return to work or sport
- The device has low stretch and maintains high strength under repeated long-term loading
Data
There are several studies on the Infinity-Lock Button System, from different centres, all with excellent results. Download summary of clinical data.
- Series of 15 patients, Rockwood Grade III AC joint dislocations, 18 month follow-up
- Series of 15 patients, Rockwood Grade IV, V acute and Grade III chronic, controlled, followed for minimum 3 months
- Series of mixed grade AC joint dislocations, 15 cases
The studies used different function scoring systems but showed good improvement. Romano et al reported CMS scores of 95 at 18-month follow up. Loukovitis et al used the Nottingham clavicle score, the patients treated with Infinity-Lock Button System had a mean score of 80 at follow-up, the control group score was 69. Chowdhury et al used the Oxford score, recording 40.5 (maximum 48) improved from 16.2 pre-operatively (no control group).
Two studies also measured the reduction, with 7.4 mm and 8.2 mm mean reductions in clavicle-coracoid distance. There were only two instances of loss of reduction in the 45 cases across all three reports.

Pec Major
The pectoralis major tears are uncommon
injuries; however, ruptures have become more
prevalent in the past 20-years, attributed to an
increase in recreational weight-lifting and
sports participation.
Pec tears can be managed non-operatively; however, for patients who are active in the gym, performing movements such as bench pressing, there will be a noticeable weakness on the affected side. There can also be a significant cosmetic difference between the injured side and the non-injured side which tends to be unacceptable to those who train regularly in a gym.
For partial or full-thickness chronic tendon tears, the Poly-Tape 20 mm tape provides a suitable graft option to augment the repair.

Rotator Cuff
Treat RC tears with confidence
Maintaining the integrity of surgical repair of massive rotator cuff tears is a complex problem, with patients experiencing high re-tear rates. Pitch-Patch reinforces the repair in cases where either the soft tissue is weak, or the repair is incomplete. Published results on rotator cuff tears treated with Pitch-Patch show low re-tear rates over five-year follow-up.
Surgical Technique
Features and Benefits
Low re-tear rate
14% in massive cuff tears, over 5-year follow-up. This is substantially below the published levels for cuff repair without augmentation or with bioresorbable patches, reported up to 94%
Strong
Very high strength of 355 N when fully sutured along the medial and lateral edges.
Sustained
improvement
Function and pain reduction scores improved over at least five years postoperatively.
Flexible
Suitable for arthroscopic or open technique: - Long shelf life, no special storage or pre-operative preparation. - Anatomical design in two sizes for varying patient anatomy and tear size. - Intra-operative decision on whether reinforcement is needed.
Even for poor tissue
quality
Indicated for patients where either the rotator cuff tear cannot be completely repaired using normal methods and/or the quality of the soft tissue is poor.
Tissue intergration
The device structure allows a natural body response whereby native tissue integrates into the device.
Data
A prospective study on the repair of massive cuff tears reinforced with Pitch-Patch has been conducted, with results reported at a minimum of five-years post surgery. The excellent functional outcomes continued to improve between the one-year and five-year timepoints (figure 1). There was only 14% re-tear rate1 and only one of those cases requiring a second surgery, compared to re-tear rates up to 94 % reported in the literature for repair of massive tears.
A separate retrospective study followed a group of patients with short tendon length (14 mm or less), with significant improvement in functional and structural outcomes. There were only three clinical failures (20%). Re-tears occurred in 53% of patients, but these were not associated with inferior outcomes compared with intact cuff repairs. Speak with a specialist for more detail on the clinical data relevant to Pitch-Patch.

Foot & Ankle
Spring Ligament
Adult Acquired Flatfoot Deformity (AAFD) is a condition defined by “medial foot arch insufficiency” , which is commonly caused by Posterior Tibial Tendon Dysfunction (PTTD) or deltoid spring ligament complex incompetency. Both etiologies have undergone substantial research to better understand their course and treatment. In severe AAFD, increasing tension on the interosseous and spring ligaments causes progressive peritalar subluxation, followed by deltoid and spring ligament insufficiency.
