Introduction:
Arthroscopy has revolutionized the field of joints repair, offering minimally invasive procedures that significantly reduce patient recovery time and post-operative complications. One crucial aspect of arthroscopic surgery is the selection of suture anchors, which play a vital role in stabilizing and repairing damaged tissues within the joint. This article aims to compare the performance and benefits of three commonly used suture anchor types: Titanium Suture Anchors, PEEK Suture Anchors, and All-Suture Anchors.
Basic Insights of Suture Anchor:
Suture anchors are a type of medical device, which is widely used in arthroscopic surgeries for securing soft tissue to bone. They are inserted into the bone to provide good fixation and support. However, the suture anchors seem the same but have different purposes, there are several types of suture anchors available in different sizes, materials, and designs.
The story of the suture anchor began with metal. The first suture anchor was made in 1985. It was composed of titanium (Ti) material and designed for Bankart labral shoulder surgery.
Thanks to its continuous improvements in procedures and innovations. A number of musculoskeletal tissues can now be repaired with suture anchors, including rotator cuff, femoral acetabular impingement, meniscus extrusion & tears, patellar tendons ruptures, and Achilles tendon ruptures etc. It is also beneficial for hip, elbow, hand, wrist, foot, and ankle surgery.
Characteristics of Good Suture Anchor:
The following are the characteristics of a good suture anchor:
· Fix the suture to the bone.
· Not to pull out of the bone under stress
· Easy to insert
· Make room for arthroscopic knot tying
· Capable of holding multiple sutures
· Has no long-term effects
Note: Selecting the appropriate suture anchor is a decision influenced by various factors, including patient characteristics, anatomical location, and surgeon preferences. While titanium anchors continue to be reliable and versatile, PEEK anchors and all-suture anchors offer distinct advantages in specific scenarios. Surgeons should consider the type of tissue being repaired, the patient’s overall health, and the desired post-operative outcome when making this decision.
Types of Suture Anchors:
The following are the top 3 different types of suture anchors. Take a look at our wide selection of suture anchors and discover the perfect solution for a reliable bone fixation:
Titanium Suture Anchors:
Titanium suture anchors have long been the gold standard in arthroscopic surgery due to their biocompatibility and excellent strength. The metallic composition offers rigid fixation to bone, providing stability and reducing the risk of anchor loosening over time. Titanium anchors can be inserted using various techniques, such as the drill, tap, and screw, allowing surgeons to adapt to different anatomical locations and tissue types. Moreover, titanium’s radiopaque nature enables clear visualization during imaging procedures.
Features:
· Superior pull-out strength
· Radiographic visibility & MRI compatibility
· Biocompatibility
· Available in various sizes and designs
· Self-punching and screwing
PEEK Suture Anchors:
Polyether-Ether-Ketone (PEEK) suture anchors are gaining popularity in arthroscopy due to their unique advantages. PEEK is a thermoplastic polymer known for its biocompatible properties, allowing for reduced tissue irritation. Compared to titanium, PEEK has a lower modulus of elasticity, minimizing the stress-shielding effect and providing a more natural load-sharing environment. PEEK anchors also possess radiolucency, which allows better visualization of tissues during post-operative imaging. Additionally, their fully threaded design provides a larger surface area for tissue contact, enhancing the potential for healing and integration.
Features:
· Radiolucency & MRI compatibility
· Elastic modulus similar to bone
· Reduced thermal conductivity
· Limited availability of designs and sizes when compared to titanium counterparts
· Highest Biocompatibility
All Suture Anchor:
All-suture anchors, as the name suggests, are composed entirely of suture material, removing the need for bulky anchor bodies. These anchors offer excellent pull-out strength and fixation by distributing the load across a larger area. The smaller anchor size enables surgeons to place more anchors within a limited space, providing improved tissue approximation. All-suture anchors are known for their minimal bone removal and reduced surgical trauma, making them particularly suitable for delicate anatomical areas.
Features:
· Minimal bone removal
· Improved tissue-to-implant ratio
· Less radiographic visibility & MRI compatibility
· Fixation against the cortex
· Revision ability

Wrap Up
As time advances, a suture anchor is playing a vital role in orthopaedics and sports medicine. The suture anchor is ideal for fixing soft tissue to bone and maintaining the position of these attachments; until the healing process has reached its full potential.
When considering suture anchor options for arthroscopic procedures, surgeons must weigh various factors related to strength, biocompatibility, radiographic visibility, and surgical technique. Titanium suture anchors offer excellent pull-out strength, biocompatibility, and radiographic visibility. PEEK suture anchors provide radiolucency and bone-like modulus of elasticity. All-suture anchors present advantages in minimal bone removal and improved tissue-to-implant ratio. Ultimately, the choice of suture anchor should be based on the specific surgical indication, surgeon preference, and patient-specific factors to achieve optimal clinical outcomes.
