To compare the mid-term outcomes in intra-articular distal humerus fracture (AO/OTA type C) treated with either open reduction-internal fixation (ORIF) or total elbow arthroplasty (TEA) in patients older than 75 years and with more than five years of follow-up. ⋯ Although there were no differences in mid-term functional outcomes between either treatment, our results suggest that the recent trend towards the use of TEA instead of ORIF in the elderly should be re-examined due to the high rate of complications beyond five years of follow-up with TEA.

This study aimed to evaluate the safety and efficacy of fusiform capsulectomy of posterior capsule in correcting severe flexion contracture during total knee arthroplasty (TKA). ⋯ The technique of fusiform capsulectomy of posterior capsule to correct the severe flexion contracture during primary TKA is safe and effective and could provide good short-term results.

The accuracy of robot-assisted pedicle screw implantation is a safe and effective method in lumbar surgery, but it still remains controversial in lumbar revision surgery. This study evaluated the clinical safety and accuracy of robot-assisted versus freehand pedicle screw implantation in lumbar revision surgery. ⋯ Compared with freehand screw implantation, in lumbar revision surgery, the Renaissance robot had higher accuracy and safety of pedicle screw implantation, fewer superior level facet joint violations, and less intra-operative blood loss and intra-operative fluoroscopy time.

In upper and chronic brachial plexus injuries for which neurological surgery is not a good treatment option, one possibility for gaining elbow flexion is free functional muscle transfer. The primary aim of our study was to evaluate the elbow flexion gain achieved by free gracilis muscle transfer with partial ulnar nerve neurotization. ⋯ In patients with upper and chronic brachial plexus injuries, free gracilis muscle transfer with ulnar nerve neurotization yields a satisfactory gain in elbow flexion strength and is therefore a good treatment option.

Stromal vascular fraction (SVF) as an injectable regenerative therapy for knee osteoarthritis (OA) has gained recent popularity. However, there is no clear consensus on the outcomes of such treatment. We systematically reviewed available evidence on the use of SVF injection in the treatment of knee OA. ⋯ Intra-articular injection of SVF is a safe and effective technique for the management of knee OA. However, comparative Level I studies are needed to support the use of adjuvants with SVF and also to compare the use of SVF (with or without adjuvants) with ADMSCs, PRP, and bone marrow concentrate.
