Shoulder Replacement

Conventional Total Shoulder Replacement

In a traditional (anatomic) total shoulder replacement:

​

  • The damaged humeral head (ball) is removed and replaced with a durable metallic ball attached to a stem positioned within the arm bone.

  • The socket (glenoid) is carefully prepared and resurfaced with a high-grade polyethylene (medical plastic) liner.

  • The socket component is secured with specialized bone cement to ensure long-term stability.

​

This time-tested procedure reliably relieves pain and restores motion in appropriately selected patients.

Personalized Implant Selection — Based on You

True excellence in shoulder replacement lies in personalization, choosing the precise implant and reconstruction strategy tailored to the individual. Dr. Petty does not believe in a one-size-fits-all approach.

​

For lower-demand patients or those with specific anatomical considerations, he utilizes proven conventional systems, including implants from Zimmer Biomet, selected for durability, proven reliability, and consistently strong clinical outcomes.

​

For technically complex cases, including deformity or bone loss, Dr. Petty performs advanced reconstructions that may include:

​

  • Metal baseplates for enhanced socket fixation

  • Modular plastic liners for improved stability

  • Customized components for optimal biomechanics

 

Every decision is driven by anatomy, lifestyle, and long-term success.

Advanced Technology for the Most Complex Cases

For the most demanding shoulder reconstructions, Dr. Petty utilizes the Arthrex VIP System, one of the most advanced planning systems available.
 

This system provides:

​

  • CT-based 3D modeling of your exact shoulder anatomy

  • Computer-guided preoperative planning

  • Patient-specific surgical models

  • Increased accuracy in implant positioning

 

The result is greater precision, improved implant alignment, and optimized long-term outcomes.

​

Successful shoulder replacement depends on:
 

  • Accurate implant positioning

  • Stable fixation

  • Proper joint biomechanics

  • Surgeon experience

 

Dr. Petty combines modern implant technology with meticulous surgical technique to restore mobility while protecting long-term joint function.

Partial Shoulder Resurfacing / Hemiarthroplasty

Bone Preservation. Maximum Strength. Unrestricted Performance.

For younger, high-demand patients who are not ready for a full shoulder replacement, Partial Shoulder Resurfacing (Hemiarthroplasty) offers a powerful, bone-preserving solution designed for strength, durability, and return to elite performance.

​

Dr. Petty frequently performs shoulder resurfacing in:

​

  • Athletes

  • Firefighters

  • Military special forces operators

  • Weightlifters

  • Highly active professionals

 

This procedure preserves the native humeral head by capping it with a durable metal hemisphere, such as the Arthrosurface OVO, rather than removing the entire ball and placing a stemmed implant.

Why Resurfacing?

  • Preserves bone

  • Avoids stem placement down the arm

  • Maintains native anatomy

  • Facilitates potential future procedures if ever needed

  • Allows return to high-level activity

 

The socket is often left natural and addressed only if necessary, maintaining as much of the patient’s own anatomy as possible.

25 Years. Zero Loosening.

Dr. Petty has performed shoulder resurfacing procedures for over 25 years with zero loosening or implant failures to date.

​

Patients return to unrestricted activity, including heavy lifting and tactical performance, with confidence and stability. It is a strategic solution for the right candidate.

Reverse Total Shoulder Replacement —
Stability for Complex Rotator Cuff Deficiency

When advanced arthritis is combined with a severely torn rotator cuff, traditional shoulder replacement may not provide stability. Reverse Total Shoulder Replacement is specifically engineered to restore function when the rotator cuff can no longer support the joint.

How It Works

Unlike traditional replacement, reverse shoulder replacement:

​

  • Reverses the ball-and-socket orientation

  • Places the ball on the socket side

  • Allows the deltoid muscle, not the damaged rotator cuff, to power the shoulder

 

This design restores stability, improves strength, and relieves pain in patients who otherwise have limited surgical options.

Experience Matters

Dr. Petty has performed reverse shoulder replacements for over 15 years, primarily utilizing the DJO Reverse Shoulder System, a system known for durability and biomechanical reliability.

​

To date, Dr. Petty has experienced:

​

  • No dislocations

  • No component failures

What Patients Can Expect

  • Excellent pain relief

  • Improved daily function

  • Clear activity guidelines designed to protect the implant

  • Stable, dependable shoulder mechanics

A Commitment to Excellence

Across all joint replacement procedures, Dr. Petty’s philosophy remains consistent:

Use High-quality Implants

Employ Precise, Reproducible Surgical Techniques

Minimize Complications

Maximize Durability and Patient Satisfaction

His mission is simple: restore movement, preserve performance, and deliver results that last.
