Serial structural MRI evaluation of arthroscopy rotator cuff repair: does Sugaya's classification correlate with the postoperative clinical outcomes?
Sugaya's classification is the most commonly used for postoperative evaluation of rotator cuff repairs. However, the correlation between this classification and clinical outcomes after supraspinatus tendon repair were not performed with serial MRI examinations in standardized time intervals. ⋯ The pain was more intense in patients classified as types III, IV, or V of Sugaya's classification. The postoperative appearance of the supraspinatus tendon was not correlated with the Constant and UCLA scales. The occurrence of type II, the most prevalent, decreased over time, whereas the occurrence of type I increased; these differences were not significant. Level de evidence: prospective cohort evaluation-level III.

Importance of additional temporary pin fixation combined coracoclavicular augmentation using a suture button device for acute acromioclavicular joint dislocation.
We evaluated the outcomes of coracoclavicular (CC) augmentation using a suture button device with additional temporary pin fixation for acute acromioclavicular (AC) joint dislocation. ⋯ Level-IV, Retrospective Case Series, Treatment Study.

A novel method to measure femoral component migration by computed tomography: a cadaver study.
Radiostereometric analysis (RSA) is the most accurate technique to measure implant migration. However, it requires special equipment, technical expertise and analysis software and has not gained wide acceptance. The current paper analyzes a novel method to measure implant migration utilizing widely available computer tomography (CT). ⋯ CT based measurement of head displacement in a cadaver model were highly accurate and reproducible.

Duration of sick leave after shoulder arthroscopy in Germany: analysis of health care data.
The expected duration of incapacity after arthroscopic shoulder surgery is an important factor for therapy planning. The aim of this study was to analyze the duration of sick leave after arthroscopic shoulder surgery in Germany and to identify factors associated with a longer duration of sick leave. We hypothesized that certain patient-related factors may be associated with a longer duration of sick leave. ⋯ The duration of sick leave after arthroscopic shoulder surgery in Germany does not exceed sick leave duration in other countries. More complex procedures, advanced age and sick leave beginning prior to surgery resulted in longer durations of sick leave. Preoperative prognosis of the necessary duration of postoperative sick leave may not always be realistic. An extended period of sick leave can be expected after more complex procedures and in patients older than 50 years of age. Future studies should investigate whether a longer period of physiotherapy may help to shorten the period of postoperative sick leave.

Real-time elastography of patellar tendon in patients with auto-graft bone-tendon-bone anterior cruciate ligament reconstruction.
Patellar tendon donor site has been previously evaluated in patients with auto-graft bone-tendon-bone (BTB) anterior cruciate ligament (ACL) reconstruction using either magnetic resonance imaging or B mode ultrasound. However, donor site patellar tendon strain ratio-reflecting structural features-has not been studied with US elastography. Here, we ascertain real-time elastography properties of patellar tendon donor site and clinical relevance of these properties in patients with auto-graft BTB ACL reconstruction in the postoperative period. ⋯ Patellar tendons on the operated sides seemed to thicken and shorten with decreased strain ratios at the donor side compared to the healthy side at an average of 2-year follow-up in patients with ACL reconstruction using BTB autograft, and amount of smoking had negative relationship with strain ratio of donor patellar tendon.
