Multicenter StudyEpidemiology of the Frequency, Etiology, Direction, and Severity (FEDS) system for classifying glenohumeral instability.
The purpose of this multicenter epidemiologic study was to determine the distribution of patients within the Frequency, Etiology, Direction, and Severity (FEDS) classification system to determine which categories are of clinical importance. ⋯ There are 16 categories within the FEDS classification that are clinically significant. Solitary, traumatic, anterior dislocation and occasional, traumatic, anterior dislocation were the most frequently observed in our cohort.

The role of meniscal tears and meniscectomy in the mechanical stability of the anterior cruciate ligament deficient knee.
The role of an intact meniscus in providing mechanical stability to the knee of anterior cruciate ligament (ACL) deficient and ACL reconstructed patients has not been well studied. ⋯ PHMM acts as a secondary stabilizer of the knee joint in the absence of functional ACL. There is no effect of partial meniscectomy on mechanical stability of the knee in ACL reconstructed patients. Medial or lateral partial meniscectomy performed at the time of ACL reconstruction does not affect the stability of ACL reconstructed knee. However, the presence of a concomitant tear in PHMM is associated with increased instability in ACL deficient knee.

Until now, there has been a lack of in vivo analysis of the correlation between bony morphological features and laxity values after an anterior cruciate ligament (ACL) injury. ⋯ A higher antero-posterior laxity at 30° and 90° of flexion was found in those with a lateral tibial slope <5.5°.

Clinical TrialIntraoperative medial joint laxity in flexion decreases patient satisfaction after total knee arthroplasty.
The relationship between postoperative tibiofemoral ligament balance and patient satisfaction in total knee arthroplasty (TKA) has been explored previously. However, the optimal intraoperative medial-lateral ligament balance during knee flexion in terms of postoperative patient satisfaction remains unknown. We evaluated the effect of intraoperative flexion instability on patient satisfaction after TKA. ⋯ Therapeutic study, Level III.

Observational StudyLongitudinal observational study of reverse total shoulder arthroplasty for irreparable rotator cuff dysfunction: results after 15 years.
This study investigated the hypothesis that functional outcome remains significantly improved over the preoperative state beyond 15 years of reverse total shoulder arthroplasty (RTSA) for irreparable rotator cuff dysfunction. ⋯ This early series of RTSA shows a substantial complication and failure rate. If, however, complications can be treated without removal of the implants, outcome is not compromised. Overall shoulder function and subjective outcome remained significantly improved and highly satisfactory during the entire study period.
