Arthroscopy Implants: Types, Uses, and Selection Guide

Introduction: Why the Right Implant Matters in Arthroscopic Surgery

When a patient in Bengaluru tears an ACL playing football or suffers a rotator cuff injury at the gym, the conversation with the surgeon quickly turns to surgery. What most patients do not realise is that the outcome of that surgery depends not only on the surgeon's skill but also on a small, precisely engineered device placed inside the joint: the arthroscopy implant.

Arthroscopic surgery has transformed orthopaedic care across India. Unlike traditional open surgery, keyhole arthroscopy uses portals of just 5 to 10 mm, causing minimal soft tissue disruption and allowing patients to recover in weeks rather than months. At the heart of every arthroscopic repair is a carefully chosen implant, and selecting the wrong one can result in fixation failure, graft loosening, or the need for revision surgery.

This guide covers every major category of arthroscopy implant, explains the clinical reasoning behind implant selection, and helps you understand what your surgeon is considering when they plan your procedure at Sports Orthopedics Institute, Bengaluru.

What Are Arthroscopy Implants?

Arthroscopy implants are small medical devices inserted through keyhole incisions to repair, reconstruct, or stabilise damaged joint structures such as ligaments, tendons, cartilage, and labral tissue. They act as anchors, fixation points, or scaffolds that hold repaired tissue in place while the body heals.

The three primary functions of arthroscopy implants are:

• Fixation: Securing tendon or ligament grafts to bone (e.g., ACL reconstruction screws).

• Reattachment: Anchoring torn soft tissue back to its bone insertion (e.g., rotator cuff suture anchors).

• Reconstruction: Providing a scaffold or buttress for joint stabilisation (e.g., Latarjet titanium screws for shoulder instability).

Main Categories of Arthroscopy Implants

Orthopaedic surgeons in India use several categories of arthroscopy implants, each designed for a specific clinical situation. Understanding these categories helps you ask informed questions before surgery.

1. Suture Anchors

Suture anchors are perhaps the most widely used arthroscopic implant in shoulder and knee surgery. They consist of a small anchor body that is drilled or screwed into bone, with one or more sutures pre-loaded through an eyelet. The sutures are then used to tie the torn soft tissue back to the bone.

Suture anchors are used in:

• Bankart repair and labral reconstruction for shoulder instability

• Rotator cuff repair (partial and full thickness tears)

• SLAP (Superior Labral Anterior to Posterior) repair

• Ankle ligament reconstruction (ATFL and CFL repair)

• Hamstring tendon reattachment to the ischial bone

Suture anchors come in three material types:

Titanium Suture Anchors

Titanium anchors are the original gold standard in arthroscopic fixation. Made from medical-grade titanium alloy (Ti6Al4V ELI), they provide exceptional pull-out strength and proven long-term biocompatibility. Their radiopaque nature means they are clearly visible on post-operative X-rays, which simplifies monitoring and revision planning.

Titanium anchors are the preferred choice when:

• Maximum holding strength is needed, such as in large rotator cuff repairs.

• The patient is elderly with reduced bone density where bone ingrowth is uncertain.

• The surgeon anticipates future revision surgery, since titanium remains easy to locate on imaging.

• The repair site is in a high-load zone, such as the 3 o'clock position in a Bankart repair.

A key consideration in India is that titanium anchors can cause MRI scatter artefact, which may occasionally complicate post-operative imaging. However, modern titanium alloys produce far less artefact than earlier stainless steel devices.

PEEK (Polyether-Ether-Ketone) Suture Anchors

PEEK has emerged as a highly popular implant material across India's leading orthopaedic centres. It is a high-performance thermoplastic polymer with a modulus of elasticity close to cortical bone, which reduces stress shielding and promotes a more natural load transfer through the repaired tissue.

Key advantages of PEEK suture anchors include:

• Radiolucency: PEEK does not appear on X-rays or MRI scans, enabling cleaner post-operative imaging.

• No metallic artefact on MRI, which is valuable in India where post-operative MRI review is increasingly common.

• Bone-like stiffness reduces the risk of anchor loosening from mechanical mismatch.

• No degradation over time, unlike bioabsorbable anchors.

PEEK anchors are ideal for younger, active patients who may require post-operative MRI assessment, or for procedures where imaging follow-up is critical, such as SLAP repairs and posterior labral reconstructions.

At Sports Orthopedics Institute, PEEK anchors and PEEK-titanium hybrid anchors are routinely used in shoulder stabilisation procedures including Bankart repair and SLAP repair.

Bioabsorbable (Biocomposite) Suture Anchors

Bioabsorbable anchors are made from materials that gradually dissolve in the body over months to years. Early-generation bioabsorbable anchors used poly-glycolic acid (PGA), which was abandoned due to rapid strength loss and inflammatory reactions. Modern bioabsorbable anchors use poly-L-lactic acid (PLLA) or PLLA combined with beta-tricalcium phosphate (beta-TCP), which is also called a biocomposite.

The main advantage of bioabsorbable anchors is that as they resorb, bone can theoretically grow in their place. However, they are not suitable in all situations:

• They require 8 to 12 weeks to achieve full biological integration, so they are not appropriate for patients with very early aggressive rehabilitation.

• In patients with poor bone quality, pure PLLA anchors may not achieve adequate pull-out strength.

• Rarely, incomplete resorption can cause a foreign body reaction or cyst formation, particularly with older PLLA formulations.

Modern biocomposite anchors (PLLA with beta-TCP) have largely addressed these concerns and offer reliable outcomes for rotator cuff repair, Bankart repair, and ankle ligament reconstruction, particularly in younger patients who will not require future revision surgery in the near term.

All-Suture Anchors

All-suture anchors represent the newest generation of suture anchor design. As the name suggests, the anchor body itself is made entirely of ultra-high molecular weight polyethylene (UHMWPE) suture material with no rigid anchor body.

These anchors are gaining popularity because:

•       They require only a very small drill hole, preserving bone stock.

•       Multiple anchors can be placed in tight anatomical spaces.

•       They are fully radiolucent and cause no imaging interference.

•       Pull-out strength is excellent in good quality bone.

All-suture anchors are particularly well-suited for paediatric patients, for small joint applications (such as wrist and elbow arthroscopy), and for situations where bone preservation is critical. They are less reliable in osteoporotic or very soft bone.

2. Interference Screws

Interference screws are the primary implant used in ligament reconstruction surgery, most commonly ACL (Anterior Cruciate Ligament) and PCL (Posterior Cruciate Ligament) reconstruction. An interference screw is inserted into the bone tunnel alongside the tendon graft, creating compression between the graft and the tunnel wall to achieve secure fixation.

At Sports Orthopedics Institute, ACL reconstruction is one of the most commonly performed procedures, and interference screw selection follows a clear clinical protocol. Learn more about the full range of ACL treatment options on the

ACL Treatment Options page.

Titanium Interference Screws

Titanium interference screws provide the highest initial pull-out and toggle resistance of any screw type. They are recommended when:

• The tendon graft diameter is thin (less than 8 mm) and maximum fixation security is needed.

• Revision ACL reconstruction is being performed, where a stiff, reliable implant is preferred.

• Bone-Tendon-Bone (BTB) grafts are used, as titanium screw-to-bone contact optimises bone-to-bone healing.

Biocomposite Interference Screws

Biocomposite screws, made from PLLA combined with beta-TCP or hydroxyapatite, are widely used in India for primary ACL reconstruction with hamstring grafts. Their advantages include:

• Gradual resorption over 2 to 4 years, allowing bone to fill the tunnel as the screw dissolves.

• No metallic interference on post-operative MRI, which is valuable for graft assessment at 6 months.

•  Good initial pull-out strength comparable to titanium in well-prepared tunnels.

The most widely used fixation construct for ACL reconstruction in India currently combines a titanium cortical button (tight rope) on the femoral side with a biocomposite screw on the tibial side, providing both the initial strength of metal and the resorption benefit on the tibial cortex. This is the standard technique at Sports Orthopedics Institute.

PEEK Interference Screws

PEEK interference screws occupy a middle ground between titanium and biocomposite. They are non-absorbable and radiolucent, making them useful when the surgeon wants permanent fixation without imaging interference. PEEK screws are increasingly used in elite athletes where post-operative MRI review of graft integration is a priority.

3. Cortical Suspension Devices (Endobuttons and Tight Ropes)

Suspension devices are small titanium or PEEK buttons attached to high-strength polyethylene tape or suture. They are looped through the graft and flipped against the outer cortex of the femur or tibia, suspending the graft at the aperture of the tunnel.

The tight rope with fibre tape and titanium button is the most commonly used femoral fixation device for ACL reconstruction in India. It offers:

•  Adjustable loop length, allowing graft tensioning intra-operatively.

•  Extremely high pull-out strength at the cortex.

•   A small bone footprint, preserving bone stock for potential future revision.

The same principle applies to AC (Acromioclavicular) joint reconstruction, where a tight rope device with buttons fixes the clavicle back to the coracoid. Read more about this procedure on the

AC Joint Reconstruction page.

4. Meniscal Repair Devices

Meniscal tears are among the most common knee injuries seen in Indian sports clinics. When the tear is in the vascular zone (the outer one-third of the meniscus where blood supply is present), repair is preferred over removal, particularly in younger patients.

Modern arthroscopic meniscal repair uses all-inside devices that combine two small PEEK or bioabsorbable anchors pre-loaded with non-absorbable UHMWPE sutures. These all-inside systems allow the surgeon to repair even complex tears without the need for additional posteromedial or posterolateral portals.

The choice of implant for meniscal repair depends on:

• Tear location: All-inside devices suit mid-body and posterior horn tears. Inside-out sutures are preferred for complex anterior tears.

• Tear pattern: Vertical longitudinal tears have the best biology for healing; radial tears and root tears may need reinforcement with additional anchors.

• Patient age and activity: Repair is always the first choice in patients under 40 who are willing to follow a protected weight-bearing rehabilitation protocol.

For patients with combined ACL and meniscal injuries, detailed arthroscopic treatment is described on the Arthroscopy Knee page.

5. Knotless Anchors

Knotless anchors are a specialised suture anchor design where the suture is tensioned and locked within the anchor body itself, eliminating the need to tie arthroscopic knots. This is a significant technical advantage because poorly tied arthroscopic knots are one of the most common causes of early construct failure.

Knotless anchors are widely used in:

• Rotator cuff repair using the double-row bridge technique, which compresses the repaired tendon footprint against the bone.

• Bankart repair where a precise, reproducible tissue tension is required.

• Ankle ligament repair (Internal Brace technique with fibre tape), which is a procedure that has gained significant popularity across India.

How Surgeons Choose the Right Implant: Factors That Matter

Implant selection is not based on brand preference alone. Experienced arthroscopic surgeons at institutions like Sports Orthopedics Institute consider multiple patient and surgical factors before deciding on an implant.

• Bone Quality: In elderly patients with osteopenia, titanium anchors or large-diameter PEEK anchors are preferred because they achieve reliable pull-out strength in soft cancellous bone. All-suture anchors and small bioabsorbable anchors are less reliable in low-density bone.

• Patient Age and Activity Level: Young, active patients who will likely need post-operative MRI assessment benefit from radiolucent PEEK or biocomposite implants. Elderly, lower-demand patients may do well with titanium, which has the longest clinical track record.

• Rehabilitation Protocol: Early aggressive rehabilitation protocols require implants with high initial strength at 14 days. Bioabsorbable implants take longer to achieve full biological fixation and may not suit patients starting active motion within the first two weeks.

• Revision Surgery Risk: If a patient has had a previous repair or if revision surgery may be needed in the future, permanent implants such as titanium or PEEK are preferred because they remain easy to localise on imaging.

• Imaging Requirements: For athletes or patients with complex repairs where MRI review is anticipated at 6 months, radiolucent implants (PEEK, biocomposite, all-suture) ensure that the repaired structure can be assessed without metallic artefact.

• Joint and Procedure Type: Different joints place different mechanical demands on implants. The shoulder, which moves through a wide arc of motion under variable loads, demands implants with high fatigue resistance. The knee, particularly after ACL reconstruction, requires graft tunnel fixation that can withstand rapid deceleration forces from early walking and later running.

Arthroscopic Implants in India: What Patients in Bengaluru Should Know

The arthroscopic surgery market in India has grown substantially over the past decade, driven by increasing sports participation, greater awareness of joint health, and the availability of high-quality implants from both Indian manufacturers and global companies. Indian orthopaedic implant manufacturers now produce CE and FDA-approved arthroscopic implants that meet the same quality standards as international brands, offering significant cost advantages for patients.

In Bengaluru specifically, the demand for arthroscopic procedures has risen sharply, driven by the city's large IT workforce, active young population, and growing participation in recreational sports such as cricket, football, badminton, and running. Conditions treated most frequently at Sports Orthopedics Institute include ACL tears, meniscal injuries, rotator cuff tears, shoulder instability, and ankle ligament injuries.

When patients from Bengaluru and across Karnataka ask about implant costs, they should understand that implant choice directly affects the overall procedure cost. Titanium implants, biocomposite screws, and PEEK anchors vary in price, and surgeons at Sports Orthopedics Institute discuss these options transparently during pre-operative consultations.

To understand more about conditions affecting different joints, explore the Bone and Joint School on the Sports Orthopedics Institute website, which covers knee pain, shoulder pain, ankle pain, hip pain, and elbow pain in detail.

Implants by Procedure: A Practical Summary

ACL Reconstruction

Standard construct: Titanium tight rope (cortical button) on the femur plus biocomposite interference screw on the tibia. For thin grafts (less than 8 mm), an all-inside technique with titanium buttons on both sides may be preferred.

Rotator Cuff Repair

Small tears (less than 1 cm): Single-row repair with PEEK or biocomposite knotless anchors. Large and massive tears: Double-row bridge technique using knotless PEEK anchors medially and laterally. Elderly patients with poor bone: Titanium anchors for maximum pull-out strength.

Bankart Repair (Shoulder Instability)

Standard repair: 3 to 4 biocomposite anchors or PEEK anchors placed along the glenoid rim. For athletes with high re-dislocation risk, knotless anchors improve tissue tension reproducibility. Bony Bankart or significant glenoid bone loss requires the Latarjet procedure with titanium screws.

Read more about shoulder stabilisation procedures at the Bankart Repair page and the

Latarjet Procedure page.

Ankle Ligament Reconstruction

Anatomical ATFL and CFL repair: PEEK or biocomposite suture anchors into the fibula.
Internal brace technique: Knotless anchor with fibre tape providing dynamic ligament augmentation.

Details on ankle procedures are available at the Ankle Ligament Surgery page.

Are Arthroscopy Implants Safe? What the Research Says

Patients frequently ask whether implants left inside the body are safe. The short answer is that modern arthroscopy implants have an excellent long-term safety record when used appropriately and implanted with correct technique.

•  Titanium implants are permanent but well-tolerated. Long-term studies confirm that titanium ions are not toxic in orthopaedic applications.

•  PEEK implants are chemically inert, non-absorbable, and do not trigger a foreign body reaction. They have been used safely in spinal and orthopaedic applications for over two decades.

•  Bioabsorbable implants (modern PLLA/beta-TCP composites) resorb over 2 to 4 years with the gradual replacement of polymer by bone. Rare complications such as synovitis or cyst formation have been reported with earlier PGA formulations, but modern biocomposite anchors have a very low complication rate.

•  All-suture anchors made from UHMWPE are biologically inert with no adverse tissue reactions in long-term follow-up studies.

The key to implant safety is accurate placement and appropriate indication selection, both of which depend on the surgeon's experience and preoperative planning.

Frequently Asked Questions (FAQ)

Q1. What is the most commonly used implant in arthroscopic ACL surgery in India?

The most commonly used construct is a titanium cortical button (tight rope) on the femoral side combined with a biocomposite (PLLA/beta-TCP) interference screw on the tibial side. This combination provides the initial fixation strength of metal at the femur with the resorption benefits of a biocomposite at the tibia.

Q2. Are bioabsorbable implants safe? Will they dissolve completely?

Modern biocomposite implants made from PLLA combined with beta-tricalcium phosphate do dissolve over approximately 2 to 4 years. As resorption occurs, bone gradually replaces the implant material. Serious complications from bioabsorbable implants are rare with modern materials. Your surgeon will recommend the appropriate type based on your specific anatomy and activity level. 

Q3. Can I get an MRI after arthroscopic surgery if I have a metal implant?

Most titanium arthroscopy implants are MRI conditional rather than MRI safe. This means MRI can usually be performed after an appropriate waiting period (typically 6 weeks), but imaging artefact from the metal may limit the quality of views near the implant. If MRI follow-up is planned, your surgeon may choose PEEK or biocomposite implants to eliminate artefact.

Q4. What is the cost difference between titanium and bioabsorbable implants in India?

Implant costs vary depending on the manufacturer (Indian versus international brands) and the specific product. Indian-manufactured biocomposite and PEEK anchors are significantly more affordable than international alternatives while meeting the same ISO and CE quality standards. Your surgeon at Sports Orthopedics Institute will discuss implant choices and their cost implications during your consultation.

Q5. How long does arthroscopic surgery take and when can I return to sports?

Arthroscopic procedures range from 30 minutes for a simple meniscal repair to 90 minutes for complex shoulder reconstruction. Return to sports depends on the procedure: most patients return to recreational sports within 4 to 6 months after ACL reconstruction and 3 to 6 months after rotator cuff repair, depending on the tear size and patient compliance with physiotherapy.

Q6. What happens if an arthroscopy implant fails or loosens?

Implant failure, though uncommon, can occur due to technical errors, patient non-compliance with rehabilitation restrictions, or implant-specific issues such as anchor pull-out in poor bone. Revision surgery is possible in most cases. Choosing permanent implants (titanium or PEEK) for the initial procedure simplifies revision planning, as they remain clearly visible on imaging.

Q7. Is arthroscopic surgery available for all age groups in Bengaluru?

Yes. Sports Orthopedics Institute in HSR Layout, Bengaluru treats patients across all age groups, from adolescent athletes with growth plate considerations to elderly patients with degenerative joint conditions. Implant selection is tailored to age, bone quality, and activity requirements.
