Case ReportsIntrathoracic shoulder dislocation causing rupture of the right main bronchus.
An intrathoracic shoulder dislocation is a rare injury, usually the result of high-energy trauma [Hawkes et al. in Am J Orthop 43(4):E74-E78, 2014; Tsai et al. in Ann Thorac Cardiovasc Surg 20:592-594, 2014, in Rupprecht et al. Bull Emerg Trauma 5(3):212-214, 2017; Abellan et al. J Orthop Surg (Hong Kong)18(2):254-257, 2010]. ⋯ Following a literature review, it appears that no cases have been reported of an intrathoracic shoulder dislocation associated with a rupture of the ipsilateral main bronchus. We present a case of a rupture of the right main bronchus that occurred due to high-energy impact and an associated intrathoracic right-shoulder fracture dislocation. Computed tomography identified diastasis of the ipsilateral first intercostal space, humeral head indentation in the hilum of the lung, and a pneumoarthrogram of the right glenohumeral joint.

Unicondylar vs. total knee arthroplasty in medial osteoarthritis: a retrospective analysis of registry data and functional outcome.
It was the aim of our study to compare the functional outcome (WOMAC score, range of motion) achieved with unicondylar knee arthroplasty (UKA) and total knee arthroplasty (TKA). It was hypothesized that UKA and TKA would differ with regard to the WOMAC function scale (hypothesis 1) and the WOMAC total scale (hypothesis 2). It was assumed that the groups would differ with respect to changes in range of motion (ROM) over time (hypothesis 3). ⋯ On the basis of our findings, it is concluded that whether knee osteoarthritis is treated with either medial UKA or TKA has no influence on the WOMAC total score or any of the WOMAC subscales. It has no effect on early or late ROM gain.

The single-suture technique for anterior cruciate ligament graft preparation provides similar stability as a three-suture technique: a biomechanical in vitro study in a porcine model.
Numerous techniques have been described for the tibial-sided graft preparation in anterior cruciate ligament (ACL) reconstruction. The use of less suture material for graft preparation is thought to improve ingrowth and to reduce the risk for infection. At the same time, the suture construct should be strong enough to resist the surgeon's pull during tensioning of the transplant. ⋯ The presented single-suture tendon graft preparation resisted to smaller failure loads than the conventional three-suture technique. However, no failures in the suture-tendon interface were seen and the failure loads observed were far beyond the tension forces that can be expected intraoperatively. Hence, the single-suture graft preparation technique may be a valuable alternative to the conventional technique.

Human umbilical cord blood-derived mesenchymal stem cell implantation for osteoarthritis of the knee.
This study aimed to investigate the clinical outcomes after human umbilical cord blood-derived mesenchymal stem cell (hUCB-MSC) implantation for medial compartment (MC) osteoarthritis of the knee. ⋯ hUCB-MSC implantation regenerated cartilage satisfactorily and showed satisfactory clinical outcomes in patients older than 60 years who had MC osteoarthritis.
