Comparative StudyClinical comparison of the two-stranded single and four-stranded double Krackow techniques for acute Achilles tendon ruptures.
Several different Krackow stitch configurations have been used for acute Achilles tendon rupture repair. Although several biomechanical studies compared different Krackow stitch configurations, to our knowledge, no previous studies compared the clinical outcome of these different suture methods. Therefore, in this study, we aimed to compare the clinical outcomes and complications of the two-stranded single and four-stranded double Krackow techniques. ⋯ III.

Kinematics of a bicruciate-retaining total knee arthroplasty.
The recently reintroduced bicruciate-retaining Total Knee Arthroplasty (BCR TKA) is an interesting approach in the quest for close replication of knee joint biomechanics and kinematics closer to the native knee. Therefore, this study aimed at providing a detailed biomechanical view on the functional resemblance of BCR TKA to the native knee joint. ⋯ As both cruciate ligaments are preserved with BCR TKA the unloaded knee closely resembles native knee kinematics including preserving the rollback mechanism. The loss of the conforming anatomy of menisci and tibial cartilage and replacement via a relatively flat polyethylene inlay may account for the loss of tibial internal rotation and the slight paradoxical AP motion of the medial femoral condyle with BCR TKA. This phenomenon reproduces findings made earlier with fixed bearing unicondylar knee arthroplasty.

Randomized Controlled TrialFunctional weight-bearing mobilization after Achilles tendon rupture enhances early healing response: a single-blinded randomized controlled trial.
Functional weight-bearing mobilization may improve repair of Achilles tendon rupture (ATR), but the underlying mechanisms and outcome were unknown. We hypothesized that functional weight-bearing mobilization by means of increased metabolism could improve both early and long-term healing. ⋯ Functional weight-bearing mobilization enhanced the early healing response of ATR. In addition, early ankle range of motion was improved without the risk of Achilles tendon elongation and without altering long-term functional outcome. The relationship between functional weight-bearing mobilization-induced upregulation of glutamate and enhanced healing suggests novel opportunities to optimize post-operative rehabilitation.

Controlled Clinical TrialProprioception after bicruciate-retaining total knee arthroplasty is comparable to unicompartmental knee arthroplasty.
Rising expectations in functional performance of total knee joints are inciting further improvement of knee arthroplasty implants. From a patient-centred view, bicruciate-retaining models provide a more natural feeling knee. However, there is no evidence of functional advantage for these implants. The aim of this study was to evaluate balance ability as a measure of proprioception in patients with a bicruciate-retaining total knee arthroplasty. ⋯ II.
