Continuous real-time biofeedback in orthosis improves partial weight bearing on stairs.
Climbing up and down stairs with crutches is a particular challenge. The current study evaluates a commercially available insole orthosis device for weighing an affected limb and for biofeedback training of gait. This study was done on healthy, asymptomatic individuals before applying to the intended postoperative patient. The outcomes should demonstrate whether a continuous real-time biofeedback (BF) system is more effective on stairs than the current protocol involving a bathroom scale. ⋯ Traditional training without biofeedback led to poor performance for partial weight bearing on stairs, even among young and healthy individuals. However, continuous real-time biofeedback clearly improved compliance, indicating its potential to enhance training and support future research in patient populations.

Lowest instrumented vertebrae selection in posterior fusion of Lenke 3C/6C adolescent idiopathic scoliosis: L3 versus L4, when LEV is L4.
In structural thoracolumbar/lumbar (TL/L) curves, lowest instrumented vertebra is selected mostly as the lower end vertebra (LEV). To save more lumbar mobile segments, fusion may be stopped one level proximal. This study aimed to compare the radiologic and functional outcomes of Lenke type 3C and 6C adolescent idiopathic scoliosis patients according to distal fusion level. ⋯ In TL/L curves which have L4 as LEV, satisfactory results can be achieved with stopping the fusion at L3, if a proper disc alignment below LIV can be obtained intraoperatively. Higher amount of LIV disc angle in L3 group did not cause coronal and sagittal imbalance. Although clinical outcomes are similar with stopping at L3 or L4, fusion to L3 may be prefered to save one more mobile disc.

Favorable outcomes of posterior cruciate-stabilized inserts over ultracongruent inserts in total knee arthroplasty.
Posterior cruciate-stabilized (PS) and ultracongruent (UC) inserts are used during total knee arthroplasty (TKA), but superiority in gaining postoperative knee flexion and functionality remains contested. Therefore, this study compared postoperative outcomes between PS and UC inserts. ⋯ III, retrospective comparative study.

Five-year polyethylene cup migration and PE wear of the Anatomic Dual Mobility acetabular construct.
Dual mobility implants have been successful in reducing postoperative hip dislocation but mid-term results of cup migration and polyethylene wear are missing in the literature. Therefore, we measured migration and wear at 5-year follow-up using radiostereometric analysis (RSA). ⋯ Anatomic Dual Mobility monoblock cups were well-fixed, the polyethylene wear rate was low, and the clinical outcomes were good until 5-year follow-up suggesting good implant survival in patients of different age groups and with heterogeneous indications for THA.

Pre-operative corticosteroid injection within 1 month of total shoulder arthroplasty is associated with increased risk of periprosthetic joint infection.
Corticosteroid injections (CSI) may increase the risk of peri-prosthetic infections (PJI) following total shoulder arthroplasty (TSA). Our study specifically assessed the risk of PJI in patients who received CSI: (1) less than 4 weeks prior to TSA; (2) 4-8 weeks prior to TSA; and (3) 8-12 weeks prior to TSA. ⋯ Level III.
