Suture anchors are among the most frequently used implants in modern arthroscopic surgery. They play a critical role in procedures such as rotator cuff repair, Bankart repair, SLAP repair, and other soft tissue fixation techniques.

Among the various anchor materials available today, PEEK (Polyether Ether Ketone) and titanium remain two of the most commonly used options. Both have demonstrated excellent clinical performance, but each offers unique characteristics that may influence implant selection.

Understanding the differences between these materials can help surgeons choose the most appropriate fixation solution for specific clinical situations.


The Role of Suture Anchors in Arthroscopy

Suture anchors are designed to secure soft tissue to bone.

Common applications include:

  • Rotator cuff repair
  • Bankart repair
  • Labral repair
  • Capsular repair
  • Tendon reattachment procedures

The anchor provides fixation while biological healing occurs between tissue and bone.

Because anchor performance directly affects repair stability, material selection is an important consideration.


What Is a Titanium Suture Anchor?

Titanium anchors have been used successfully in orthopedic surgery for decades.

Titanium is a strong metallic material known for:

  • Excellent mechanical strength
  • High durability
  • Long clinical history
  • Reliable fixation

These characteristics have made titanium anchors a trusted option in shoulder arthroscopy and sports medicine procedures.


Advantages of Titanium Anchors

High Mechanical Strength

Titanium provides excellent pull-out resistance and fixation stability.

This can be particularly useful in patients with poor bone quality.

Long Clinical Track Record

Titanium anchors have been used for many years with proven clinical outcomes.

Numerous published studies support their safety and effectiveness.

Reliable Fixation

Titanium anchors offer consistent fixation performance across a wide range of procedures.


Limitations of Titanium Anchors

Despite their advantages, titanium anchors have certain limitations.

Imaging Artifacts

Titanium may create artifacts on MRI and CT imaging.

Although modern imaging technology has reduced this issue, artifacts may still affect postoperative evaluation.

Permanent Implant Presence

Titanium remains permanently within the bone unless surgically removed.

For most patients this is not problematic, but some surgeons prefer non-metallic alternatives.


What Is a PEEK Suture Anchor?

PEEK (Polyether Ether Ketone) is a high-performance thermoplastic polymer that has become increasingly popular in orthopedic implant design.

PEEK combines excellent mechanical properties with advanced imaging compatibility.

Today, PEEK anchors are widely used in shoulder and knee arthroscopy.


Advantages of PEEK Anchors

Radiolucency

One of the most important advantages of PEEK is radiolucency.

PEEK does not create significant imaging artifacts.

Benefits include:

  • Easier MRI evaluation
  • Better postoperative imaging
  • Improved assessment of tendon healing

Excellent Mechanical Performance

Modern PEEK anchors provide fixation strength comparable to many metallic systems.

They are designed to withstand physiological loads during healing.

Biocompatibility

PEEK demonstrates excellent biocompatibility and has been successfully used in orthopedic implants worldwide.

MRI Compatibility

PEEK anchors allow improved postoperative imaging assessment compared with many metallic implants.


Limitations of PEEK Anchors

Although highly effective, PEEK anchors also have certain considerations.

Higher Material Cost

PEEK manufacturing may be more expensive than traditional metallic implants.

Surgeon Preference

Some surgeons continue to prefer metallic fixation due to familiarity and long-term experience.

Both materials provide excellent fixation when used appropriately.


Rotator Cuff Repair Applications

Both titanium and PEEK anchors are commonly used in rotator cuff repair.

Factors influencing implant selection include:

  • Tear size
  • Bone quality
  • Repair technique
  • Surgeon preference
  • Imaging requirements

Neither material has demonstrated universal superiority in all clinical situations.


Bankart Repair Applications

Bankart repair procedures frequently utilize smaller anchor systems.

PEEK anchors are often selected when postoperative MRI evaluation is important.

Titanium anchors continue to be used successfully worldwide for shoulder instability surgery.


Factors Influencing Anchor Selection

Surgeons may consider:

Patient Age

Younger patients may require long-term imaging follow-up.

Bone Quality

Bone density can influence fixation requirements.

Revision Surgery Risk

Future revision procedures may affect implant choice.

Imaging Needs

MRI evaluation may favor radiolucent implants such as PEEK.

Conclusion

Both PEEK and titanium suture anchors have established roles in modern arthroscopic surgery. Titanium anchors offer exceptional strength and a long clinical history, while PEEK anchors provide excellent imaging compatibility and radiolucency.

The optimal choice depends on patient-specific factors, surgical goals, imaging requirements, and surgeon preference. Understanding the advantages and limitations of each material helps support informed implant selection and successful surgical outcomes.
