Joint Replacement Specialist: Shoulder, Hip and Knee
Dr. Sobky utilizes cutting edge, minimally invasive methods when it comes to total joint repair surgery for hips, knees and shoulders. Some highlights include:

  • Direct Anterior Total Hip Replacement: This surgery allows for less muscle damage and pain and much faster recovery times when compared to traditional techniques.
  • Cement-free Press Fit Knee Replacement: Dr. Sobky uses implants that can allow the bone to grow and permanently bond to the implant directly instead of using cement, which helps ensure an even longer lasting replacement.
  • Reverse Shoulder Replacement: This surgery is used when there’s arthritis in the shoulder in addition to a rotator cuff tear or shoulder deformity. This revolutionary surgery can return function and decrease pain for patients who up until 10 years ago had no other option.

Sports Medicine/Arthroscopic Specialist: Shoulder/Knee
Using the latest minimally invasive techniques, Dr. Sobky offers the following shoulder and knee surgeries, most of which are day or outpatient surgeries.

  • Shoulder Surgeries: Rotator Cuff Repairs, Biceps Tendon Surgeries, Shoulder Instabilities, AC Joint Dislocations and Arthritis and Labrum Tears can often be treated arthroscopically.

Mark Tuttle, M.D.

  • Direct Anterior Hip Replacement: Dr. Tuttle uses this minimally invasive technique as it’s associated with reduced muscle damage, less pain and faster, post-operative patient recoveries.
  • Cement Free Knee Replacement: Dr. Tuttle specializes in Press Fit Knee Replacements, which utilize biological fixation rather than the usual cement on an artificial joint that mimics your real knee joint in that there’s a single radius. This means that as your knee flexes and extends, there’s a constant center of rotation. And because the original fit is so snug and flush, the implant won’t move or loosen over time.
  • Metal or Cement Allergic Replacement Surgery: Sometimes a patient might have an allergy to a metal implant or the cement (sometimes both in rare cases) and Dr. Tuttle offers solutions for metal allergy problems, cement allergy problems and even the rare combination of both.
  • Revision Surgery: Dr. Tuttle performs select revision surgeries for failed or loosed total hip and knee replacements.
  • Fracture Care: Dr. Tuttle treats fractures of the upper and lower extremities, including the scapular to the ankle and everything in between.
  • Minimally Invasive Surgery: When it comes to hip and knee replacements, Dr. Tuttle uses only the latest, most minimally invasive surgical techniques available.
