Soft tissue laxity should be considered to achieve a constant polyethylene thickness during total knee arthroplasty.
In total knee arthroplasty (TKA), the gap expansion effect by soft tissue laxity and bone resection amount influence directly on the proper gap size and ideal polyethylene insert thickness. In this study, we hypothesized if bone resection level could be controlled lesser as gap expansion effect resulted in the effects on gap expansion of the collateral release and lax lateral structure, appropriate gap size would be attained without extensive medial soft tissue release even in severe varus deformed knee. The purpose of this study was to show the usefulness of preoperative calculation of soft tissue laxity for determining the appropriate gap size for the targeted PE thickness in TKA. ⋯ This study showed the usefulness of preoperative calculation of soft tissue laxity for appropriate gap size for targeted polyethylene thickness and possibility to attain constant extension gap regardless of preoperative varus deformity.

Analysis of agreement between the German translation of the American Foot and Ankle Society's Ankle and Hindfoot Scale (AOFAS-AHS) and the Foot Function Index in its validated German translation by Naal et al. (FFI-D).
Despite its wide use in clinical outcome measurement, there is yet no validated German language version of the AOFAS-AHS available. After finishing cross-cultural adaption of the AOFAS-AHS according to the AAOS guidelines, an analysis of agreement was carried out. ⋯ Although the agreement analysis was performed for the German translation of the two questionnaires, analogous results can be expected also for other languages. It should be noted that the results do not allow for judging which of the scores is better suited to give a valid statement on patient outcome in treatment of hindfoot disorders. To verify which of these two scores is better suited to represent hindfoot-dysfunction a subsequent study using instrumental gait analysis and surface EMG is being carried out.

Bilateral tibial lengthening over the nail: our experience of 143 cases.
Using lengthening over an intramedullary nail as a technique for cosmetic purposes improves the individuals' quality of life and provides more satisfactory results due to less external fixator period. ⋯ Lengthening over an intramedullary nail provides bone formation in equal quality to that obtained by the conventional Ilizarov method, along with lower rate of complications. The large number of individuals involved in our study is a remarkable benefit which could be used as an appropriate sample to compare results for outcomes and complications.

Sufficient first aid equipment is essential to treat injuries on football fields. Deficits in first aid on field are still present in youth football. ⋯ Current first aid equipment in youth football is insufficient. Scientific-based first aid equipment with 90 € is adequate to serve all injuries. Football coaches need education in first aid management.

A single dose of platelet-rich plasma improves the organization and strength of a surgically repaired rotator cuff tendon in rats.
Rotator cuff tear (RCT) is a common cause of pain and disability among adults. Platelet-rich plasma (PRP) is a fraction of whole blood containing concentrated growth factors and proteins important for tissue healing. This study aimed at investigating the effects of local autologous PRP injection on repaired rotator cuff (RC) tendon repair in rats. ⋯ Application of a single dose autologous PRP in adjunct to surgical repair resultes in improved tendon-to-bone healing, assessed by histological and biomechanical testing in a rat model of acute RCT, when tested at 3 weeks compared to controls. Further studies will be essential to determine the role of PRP in clinical practice.
