Randomized Controlled Trial Multicenter Study Comparative Study
Calcific tendinitis of the rotator cuff: a randomized controlled trial of ultrasound-guided needling and lavage versus subacromial corticosteroids.
Calcific tendinitis of the rotator cuff (RCCT) is frequently diagnosed in patients with shoulder pain, but there is no consensus on its treatment. ⋯ On average, there was improvement at 1-year follow-up in both treatment groups, but clinical and radiographic results were significantly better in the barbotage group.

There have been no previous studies showing clinical outcomes according to treatment options of posterior cruciate ligament (PCL) injury with mild grade 2 or less posterior translation (<7 mm) combined with posterolateral rotatory instability. ⋯ Simultaneous reconstruction of the PCL and PLC is recommended when addressing PCL injuries with mild grade 2 or less posterior translation combined with posterolateral rotary instability.

Comparative Study
Biomechanical comparison of anatomic single- and double-bundle anterior cruciate ligament reconstructions: an in vitro study.
Arthroscopic identification of the anteromedial (AM) and posterolateral (PL) bundle locations of the anterior cruciate ligament (ACL) has facilitated an improved quantitative description of ACL anatomy. Few studies have directly compared the biomechanical laxity of anatomic single-bundle (SB) versus anatomic double-bundle (DB) ACL reconstruction techniques based on precise anatomic descriptions. ⋯ Although significant differences between reconstructions were observed for internal rotation, the small magnitude of these differences (<3°) may not have clinical significance.

Headache-related symptoms may be predictive of delayed recovery in student athletes after sport-related concussion. PURPOSE AND HYPOTHESIS: To compare balance performance, cognitive function, and symptom recovery in concussed student athletes with no headache, those with posttraumatic headache, and those with characteristics of posttraumatic migraine following a sport-related concussion. It was hypothesized that those with posttraumatic migraine would take longer to recover on all clinical measures. ⋯ Posttraumatic migraine characteristics are related to prolonged symptom recovery after sport-related concussion. Clinicians should exercise caution in making decisions about return to participation for athletes with migraine-like symptoms given the increased short-term impairments and delayed symptom recovery we observed.

Although previous research has demonstrated that patients with posttraumatic migraine (PTM) after concussion report more symptoms and cognitive deficits after injury than do those without PTM, it is not known whether these effects persist beyond the first week of injury or whether PTM predicts recovery time. ⋯ Results suggest that PTM is associated with cognitive impairments and protracted recovery and that headache alone is not a good predictor of recovery.
