Ligament graft fixation with bioabsorbable interference screws is a standard procedure in cruciate ligament replacement. Previous screw designs may resorb incompletely, and can cause osteolysis and sterile cysts despite being implanted for several years. The aim of this study was to examine the in vivo degradation and biocompatibility of the new Milagro interference screw (Mitek, Norderstedt, G...

Tarsal tunnel syndrome (TTS), also known as posterior tibial neuralgia is a painful disorder of the foot. It is a medical condition arising due to the compression of the tibial nerve in the tarsal tunnel, resulting in numbness, parenthesis and muscle weakness in foot. A number of imaging methodologies such as ultrasound as well as MRI imaging has been used in the past in order to analyze the st...

We read the article “Anatomical ACL reconstruction with double bundle: first 40 cases” by Zekcer A. et al [Rev Bras Ortop 2011;46(3): 262-5] with great interest and would like to make some comments on what was reported in that paper. The authors drilled an anteromedial femoral tunnel with the knee flexed at 90°. At this degree of flexion, the tunnel is significantly shorter than it is at flexio...

BACKGROUND Standard tibial motor nerve conduction measures are established with recording from the abductor hallucis. This technique is often technically challenging and clinicians have difficulty interpreting the information particularly in the short segment needed to assess focal tibial nerve entrapment at the medial ankle as occurs in posterior tarsal tunnel syndrome. The flexor hallucis bre...

Several anatomical anterior cruciate ligament (ACL) reconstruction techniques have been proposed to restore normal joint kinematics. However, the relative superiorities of these techniques with one another and traditional single-bundle reconstructions are unclear. Kinematic responses of five previously reported reconstruction techniques (single-bundle reconstruction using a bone-patellar tendon...

There is little consensus on how to optimally reconstruct the posterior cruciate ligament (PCL) and the natural history of injured PCL is also unclear. The graft material (autograft vs. allograft), the type of tibial fixation (tibial inlay vs. transtibial tunnel), the femoral tunnel position within the femoral footprint (isometric, central, or eccentric), and the number of bundles in the recons...

INTRODUCTION Quantitative data regarding the dimensions of the posterior cruciate ligament (PCL) and its insertions have not been studied in Asians, and concerns have been raised regarding the danger of vascular injury when the bony tunnels are created during arthroscopically-assisted reconstruction. MATERIALS AND METHODS Ten male cadavers were used in this study, incorporating dissection and...

BACKGROUND Allograft healing (ligamentization) after reconstruction of the anterior cruciate ligament (ACL) is dependent on multiple factors, including tissue processing, host biologic environment, and biomechanical stressors. Magnetic resonance imaging (MRI) can be used to assess graft maturation after ACL reconstruction. HYPOTHESIS A significant difference will exist in the MRI analysis bet...

Purpose: to study in cadaver knees the position of the tibial tunnel in anterior cruciate ligament (ACL) reconstruction using the 65° Howell guide. Type of study: controlled laboratory study in vitro Methods: 21 fresh-frozen cadaver knees were employed. The ACL was resected and its tibial attachment was demarcated. To drill the guide wire we employed the Howell 65 degrees tibial guide which ref...

All the information about tarsal tunnel so far is both important and variable. The reason for this situation that there are many structures in tunnel, such as tibial nerve its branches, posterior artery, veins some tendons. During routine dissection, we found an abnormal relationship between medial calcaneal (MCN) on right side of a male cadaver. In case, would show variant condition communicat...
