The interaction between the vastus medialis and vastus intermedius and its influence on the extensor apparatus of the knee joint.
Although the vastus medialis (VM) is closely associated with the vastus intermedius (VI), there is a lack of data regarding their functional relationship. The purpose of this study was to investigate the anatomical interaction between the VM and VI with regard to their origins, insertions, innervation and function within the extensor apparatus of the knee joint. ⋯ The VM consists of multiple muscle units inserting into the entire VI. Together, they build a potential functional muscular complex. Therefore, the VM acts as an indirect extensor of the knee joint regulating and adjusting the length of the extensor apparatus throughout the entire range of motion. It is of clinical importance that, besides the VM, substantial parts of the VI directly contribute to the medial pull on the patella and help to maintain medial tracking of the patella during knee extension. The interaction between the VM and VI, with responsibility for the extension of the knee joint and influence on the patellofemoral function, leads readily to an understanding of common clinical problems found at the knee joint as it attempts to meet contradictory demands for both mobility and stability. Surgery or trauma in the anteromedial aspect of the quadriceps muscle group might alter a delicate interplay between the VM and VI. This would affect the extensor apparatus as a whole.

Reliability and validation of the Dutch Achilles tendon Total Rupture Score.
Patient-reported outcome measures (PROMs) have become a cornerstone for the evaluation of the effectiveness of treatment. The Achilles tendon Total Rupture Score (ATRS) is a PROM for outcome and assessment of an Achilles tendon rupture. The aim of this study was to translate the ATRS to Dutch and evaluate its reliability and validity in the Dutch population. ⋯ Diagnostic study, Level I.

All-arthroscopic AMIC® (AT-AMIC®) technique with autologous bone graft for talar osteochondral defects: clinical and radiological results.
Autologous Matrix-Induced Chondrogenesis (AMIC®) is known to provide satisfactory clinical results for the treatment of knee, hip, and ankle cartilage lesions. The purpose of this study was to evaluate clinical and radiological outcomes of patients treated with a new all-arthroscopic AMIC® (AT-AMIC®) technique with autologous bone graft for talar osteochondral defects at a follow-up of 24 months. ⋯ IV.

ReviewDevelopment of an accelerated functional rehabilitation protocol following minimal invasive Achilles tendon repair.
Surgical repair after acute Achilles tendon rupture leads to lower re-rupture rates than non-surgical treatment. After open repair, early functional rehabilitation improves outcome, but there are risks of infection and poor wound healing. Minimal invasive surgery reduces these risks; however, there are concerns about its stability. Consequently, physicians may have reservations about adopting functional rehabilitation. There is still no consensus about the post-operative treatment after minimal invasive repair. The aim of this study was to define the most effective and safe post-operative rehabilitation protocol following minimal invasive repair. ⋯ II.
