Comparative Study
Biomechanical comparison of arthroscopically performable techniques for suprapectoral biceps tenodesis.
The aim of this study was to biomechanically compare the cyclic and ultimate failure load (UFL) of 4 widely used techniques for arthroscopically performable suprapectoral tenodesis of the long head of the biceps tendon (LHB). ⋯ The lasso-loop suture anchor technique is an appropriate alternative for suprapectoral LHB tenodesis compared with tenodesis screw techniques.

Subcutaneous emphysema of the upper extremity is rare. Crepitation on physical examination and visible gas on radiographs raise the concern of gas gangrene due to gas-producing bacteria. Rapid establishment of a differential diagnosis is necessary to initiate proper treatment. ⋯ Frequent blood tests and clinical evaluation ruled out a potentially life-threatening bacterial infection, and the signs resolved after 1 week without surgical treatment. Presumably, the intensive postoperative range-of-motion exercises led to a sucking in of air into the wound during each movement. This case illustrates that it is important to differentiate nonbacterial from bacterial causes of soft-tissue gas formation to initiate the appropriate treatment.

We investigated the effects of the beach-chair position and induced hypotension on regional cerebral oxygen saturation (rSO(2)) in patients undergoing arthroscopic shoulder surgery by using near-infrared spectroscopy. ⋯ Level IV, study of nonconsecutive patients without consistently applied reference gold standard.

Tibial plateau fracture after primary anatomic double-bundle anterior cruciate ligament (ACL) reconstruction is rare. To our knowledge, this is the first case report of a tibial plateau fracture after primary anatomic double-bundle ACL reconstruction. In our patient the tibial plateau fracture occurred after a torsional injury to the involved extremity. ⋯ The fracture was intra-articular Schatzker type IV and had a significant displacement. The patient was treated operatively by open reduction-internal fixation. He recovered well.

Randomized Controlled Trial Comparative Study
Anterior cruciate ligament reconstruction using patellar tendon versus hamstring tendon: a prospective comparative study with 9-year follow-up.
To analyze the long-term evaluation of clinical, functional, and magnetic resonance imaging (MRI) results after implant-free press-fit anterior cruciate ligament (ACL) reconstruction with bone-patella tendon (BPT) versus quadrupled hamstring tendon (HT) grafts. ⋯ Level II, prospective comparative study.
