CONTEXT Limitations in gastrocnemius/soleus flexibility that restrict ankle dorsiflexion during dynamic tasks have been reported in individuals with patellofemoral pain (PFP) and are theorized to play a role in its development. OBJECTIVE To determine the effect of restricted ankle-dorsiflexion range of motion (ROM) on lower extremity kinematics and muscle activity (EMG) during a squat. The au...

Minimizing the number of probes is one of the main challenges in reconstructing geometric objects with probing devices. In this paper, we investigate the problem of using an ω-wedge probing tool to determine the exact shape and orientation of a convex polygon. An ω-wedge consists of two rays emanating from a point called the apex of the wedge and the two rays forming an angle ω. A valid ω-probe...

We consider an inviscid fluid, initially at rest inside a wedge, bounded by one free surface and one solid surface. When t = 0, we allow the contact angle to change discontinuously, which leads the free surface to recoil under the action of surface tension. As noted by Keller and Miksis [SIAM J. Appl. Math., 43 (1983), pp. 268–277], a similarity scaling is available, with lengths scaling like t...

Background: Nowadays combined high tibial osteotomy and ACL reconstruction is accepted as a safe and effectivesurgery for patients with symptomatic varus osteoarthritis and anterior knee instability; however, the source of varusdeformity is sometimes the femoral bone. No studies have reported concomitant ACL reconstruction and distal femoralosteotomy in ACL-deficient knees wit...

In this paper, we consider the problem of placing a small number of angle guards inside a simple polygon P such that each point in the plane can determine if it is in or out of P from a monotone Boolean formula (and (.) and or (+) operations only) composed from the angle guards. Each angle guard views an infinite wedge of the plane. This class of new art gallery type problems is called sculptur...

  Background: Patients with an anterior cruciate ligament-deficient varus-angulated knee may need not only an isolated high tibial osteotomy (HTO), but also an additional anterior cruciate ligament reconstruction (ACLR). A number of prospective clinical trials have been published considering the combination of HTO and ACL reconstruction. Our aim was to investigate whether one-stage combined HTO...
