A 45-year-old patient presents with pain and swelling after undergoing an arthroscopic rotator cuff repair 10 weeks ago. On physical exam the portal sites are healed and there is no drainage. Testing of the integrity of the rotator cuff is limited secondary to pain. He has a WBC of 11.0 (reference range, 3-11 cells/mL), ESR of 40 mm/hr (reference range, 0-22 mm/hr), and CRP of 1.5 mg/dL (reference range, 0-1 mg/dL). An aspiration is completed and no organisms are seen on the gram stain. Twelve days after the aspiration, positive cultures are reported. Which organism is most likely to have grown in culture medium?

During shoulder arthroscopy of a 58-year-old female recreational golfer, the rotator cuff is examined and is seen to be intact on the articular side. After a bursectomy is performed in the subacromial space, a bursal sided tear is found measuring 1.5 cm from anterior to posterior and 4 mm in depth from the surface of the tendon with surrounding cuff softening. What is the appropriate management?
Debride the tear and perform an acromioplasty
Abort surgery and start a physical therapy program
Convert it to a full-thickness tear and repair it with suture anchors
Consider it incidental, as this is a common finding in this age group
Perform acromioplasty only
What is the average medial-to-lateral distance of the supraspinatus tendon insertion at its footprint on the greater tuberosity?
A 50-year-old man sustains a left shoulder injury after falling from a motorcycle. A physical examination test to examine for this shoulder injury is found in Figure A. What is the most likely diagnosis?
Teres minor tear
During diagnostic arthroscopic evaluation of a patient's shoulder, you identify a thickened portion of the coracohumeral ligament, near its avascular zone, running perpendicular to the supraspinatous tendon. The structure is identified in Figure A with black arrows. What is the name for this structure?
Middle glenohumeral ligament
A latissimus dorsi tendon transfer is a well established procedure for treatment of massive irreparable posterosuperior rotator cuff tears. All of the following factors have been shown to result in worse clinical outcomes after a transfer EXCEPT?

Deficiency of the subscapularis
Absence of the coracoacromial ligament

A large rotator cuff tear is repaired through 3 trans-osseous tunnels by a mini-open approach. What is the most appropriate post-operative therapy protocol?

A 50-year-old recreational league baseball pitcher reports that 3 months ago he started having right shoulder pain after every game he had pitched. One month ago he injured his shoulder further when he fell off of a ladder. He has attempted to participate in a shoulder rehabilitation program but could not return to pitching secondary to pain and weakness. Figure A demonstrates an arthroscopic image taken from a lateral portal in the subacromial space (HH= humeral head, LHB= long head of the biceps) while in the beach-chair position. What is the injury pattern sustained as highlighted by the injured structure labeled with the asterisk in Figure A?
Humeral avulsion of the glenohumeral ligament (HAGL lesion)
Superior labrum anterior-posterior (SLAP) tear
Rotator cuff tendon tear
Anterior-inferior capsulolabral lesion (Bankart lesion)
Anterior labral periosteal sleeve avulsion (ALPSA lesion)
A 65-year-old right-hand-dominant man reports acute right shoulder pain and inability to lift his arm overhead after a glenohumeral dislocation while skiing 2 weeks ago. Physical exam reveals active forward elevation to 30 degrees and 3/5 external rotation strength, pain with motion, and intact lateral arm sensation. An MRI is contraindicated due to a pacemaker, and therefore an arthrogram is performed and shown in Figure A. What is the most appropriate treatment option?
Rotator cuff repair
Proximal humerus ORIF
Total shoulder arthroplasty
A 34-year-old carpenter has left shoulder pain for the past 3 months following a fall from a ladder. Figure A displays a coronal T2 MR image. Which of the following diagnoses most appropriately describes this patient's lesion?

HPI - 45 yr old female with hx of shoulder pain had mini open cuff repair (anterior subscap / supra as per op note) 7 months ago by another surgeon.
What are her current options?
HPI - 43 yr old male with shoulder pain. Hx of cuff repair 4 years ago.
HPI - Patient was operated in Feb 2014 for supraspinatus tear right shoulder arthoscopically.Sympotms improved after surgery .At about 3 weeks post op patient developed sudden pain following physiotherapy which subsided after rest for few days.Three months after surgery patient developed severe sudden pain in right shoulder which progressively increased and was also present on rest.
Patient had no fever .
ESR was 50 and crp was negative ,counts were normal
Repeat MRI ON 26 JUNE 14 showed tear of supraspinatus infraspinatus and subscapularis along with signal changes at greater tuberosity.
After course of iv antibiotics symptoms subsided and pain releif was about 70%. After shifting to oral antibiotics pain also increased after about one week .At present pain is about 50%better and movements have slightly improved .
Serial xrays show increasing erosion around greater tuberosity
What is the diagnosis of this post operative complication
