Total Shoulder Arthroplasty

Arthroplasty is the replacement or reconstruction of a joint that has been damaged or has degenerated over time, as with arthritis. Glenohumeral osteoarthritis is the wearing out of cartilage in the shoulder joint. People who have severe osteoarthritis of the shoulder joint with accompanying long-term damage of the rotator cuff are candidates for total shoulder arthroplasty. Patients with osteoarthritis of the shoulder and an intact rotator cuff are ideal candidates for a total shoulder arthroplasty.

Total shoulder arthroplasty involves removing the damaged cartilage that lines the joint and replacing it with a metal implant. In this procedure, the ball of the shoulder is replaced with a metal ball and the socket of the shoulder is replaced with a metal socket and plastic liner. The implants used are made of titanium or cobalt chrome. They are sometimes cemented in place for additional stability.

Post Operative Instructions:


  • For the first 7 days after your surgery, you must wear your sling at all times including while you are asleep. You may only remove the sling to shower and to perform range of motion exercises for your elbow. You should flex and extend your elbow 3 to 4 times a day to prevent stiffness.In order to replace your shoulder joint, a muscle in the front of your shoulder had to be cut during your surgery. This muscle was then reattached and repaired at the end of the procedure. However, because of this you should not move your elbow away from your body as this may damage the repair. Also, do not externally rotate your arm past neutral. You can extend/raise your arm forward only, as if you were bringing your arm to a salute position. See the pictures below for what you should and should not do.

OK to do:

What NOT to do:


  • An ice machine will be provided to you prior to your surgery. This will help decrease swelling and pain after your surgery. Use the ice machine as much as possible when you get home at intervals of 30 minutes on and off. You should keep the ice machine for approximately two weeks. Do not use the ice machine while you are sleeping.


  • An injection of local anesthesia was injected into your shoulder after the completion of the operation. This medication will wear off in 5 to 6 hours. Therefore, begin taking the pain medication (e.g. Vicodin, Percocet, etc) immediately when you get home. This will prevent you from having severe pain. Take the pain medication every 4 hours until you go to bed.
  • The day after surgery you can take 600 mg of Ibuprofen (Advil/Motrin) every 6 hours to help with inflammation and pain. This medication will help cut down the use of narcotic-based pain medication. However, if you still have pain after taking the Ibuprofen, continue taking the pain medication every 4-6 hours as needed.
  • A sleeping medication (e.g. Ambien) is also provided to help you sleep at night. Take one tablet 30 minutes before you plan to sleep.


  • Your shoulder dressing is waterproof. You may shower the next day after surgery. Two days after surgery you may remove the entire dressing. Gently wash the wounds with soap and warm water and towel dry. You may then cover the incisions with band-aids until your post op visit.
  • Do not take a bath or submerge your shoulder in water until your incisions are checked at your first post-op visit.


  • You may drive 1 week after surgery if you are not taking pain medication. If your right arm is the operative side, then you must have good control of your arm prior to driving.


  • Please call the office prior to, or immediately following, your surgery in order to schedule a postoperative appointment. This should be scheduled 7-10 days after surgery. At that visit your stitches will be removed and you will be given a prescription to begin physical therapy.

Recovery Timeline:

Day of surgery: Arrive one to two hours prior to surgery. Procedure will take approximately one to two hours. Recovery time is one hour. Expect to stay in the hospital for one to two days after surgery. For immediate post-op instructions, download the instruction sheet. One week post-op: First follow-up visit with Dr. Snibbe/Jennifer. Your stitches will be taken out, and an X-ray will be taken in the office. Continue icing the surgical area two to three times a day (or more if needed). Discontinue the sling as soon as possible to avoid stiffness. Physical therapy will be prescribed. Start physical therapy immediately to work on range of motion. Four weeks post-op: Second follow-up visit. Range of motion and strength test. Physical therapy will continue to improve range of motion. Mild stiffness is still common. At this point you can start resistance and strengthening exercises. Eight weeks post-op: Third follow-up visit. Range of motion and strength testing. If additional range of motion or strength training needed, continue physical therapy to work on these. Pain should be mostly resolved at this point. Twelve weeks post-op: Fourth follow-up visit. Range of motion should be full/normal. You should feel stronger and have very little pain, if any. Near to full recovery is expected at this time.
