Patients with unicondylar knee arthroplasty (UKA) report higher functionality compared to those with total knee arthroplasty (TKA). However, these patients should also be assessed during more demanding tasks in order to appreciate their true functionality. The forward lunge (FL) is a motor task commonly used in clinics to evaluate functional recovery after knee replacement surgery. Unfortunately, clear evidence comparing FL kinematics between patients with UKA and TKA is still missing. The purpose of this study was to compare hip and knee joint kinematics during the FL between patients with UKA, TKA and controls. Twenty subjects (8 TKA, 6 UKA, 6 controls) underwent 3D motion analysis during a FL. Differences in hip and knee kinematics between groups were identified using statistical parametric mapping. We concluded that patients with TKA demonstrated reduced knee and hip flexion angles during the loaded phase of the FL, which could have been an attempt to unload the knee joint. This is in contrast to patients with UKA, who showed similar knee and hip joint kinematics compared to controls throughout the entire FL. It seems that retaining the cruciate ligaments is beneficial for the execution of a complex motor task such as the FL.
- Evaluation of a magnesium ring device for mechanical augmentation of a ruptured ACL: Finite element analysis. [Journal Article]
- CBClin Biomech (Bristol, Avon) 2019 Jun 05; 68:122-127
- CONCLUSIONS: This study offers new knowledge on the function of a ring device to mechanically augment ACL repair in order to improve its healing. Quantitative data on loading levels in the repaired ACL and its insertion site that led to its healing could be used as basis for developing novel devices to mechanically augment the healing of ACL in humans.
- Non-atherosclerotic Abdominal Vasculopathies. [Journal Article]
- AVAnn Vasc Surg 2019 Jun 11
- CONCLUSIONS: NAV are rare and can be caused by different etiologies that primarily affect females. Hypertension and tobacco use were prevalent. Various imaging strategies revealed aneurysms, stenosis, dissection and or thrombosis affecting renal and celiac arteries. Most patients improved with conservative, medical, endovascular and or surgical approach. More research is needed to standardize management approach to patients with NAV.

Bilateral inferior shoulder dislocations also known as luxatio erecta is an extremely rare injury that is commonly complicated with injuries to the humeral head, glenoid, clavicle, scapula, rotator cuff, capsule, ligaments, brachial plexus, axillary artery and vein. Our patient is a 66-year-old man who presented with both upper extremities above his head in a fixed abducted position after sliding down a ladder approximately 6-meters. Initial radiographs revealed both humeral heads to be located below the glenoid fossa with each humeral shaft parallel to the scapular spines. Computed tomography (CT) revealed a right Hill-Sachs compression fracture (posterolateral humeral head) with a bony Bankart fracture (anteroinferior glenoid) and an avulsion fracture of the left acromion. Successful closed reduction was obtained. Upon follow up, bilateral rotator cuff tears were suspected and confirmed with magnetic resonance imaging (MRI). Early recognition, treatment and follow-up is essential to minimize complications.
- Hip Arthroscopy of a Painful Hip with Borderline Dysplasia. [Journal Article]
- HPHip Pelvis 2019; 31(2):102-109
- CONCLUSIONS: The results of the current study indicate that arthroscopic management may be beneficial for a subset of patients with borderline dysplasia; however, the dissatisfaction rate associated with this treatment approach may be as high as 40%. The poor preoperative pain score appears to be the sole indicator for poor outcomes.
- Short-Term Outcome of Multi-Ligament Knee Injury among Sudanese Patients. [Journal Article]
- OAOpen Access Maced J Med Sci 2019 May 15; 7(9):1486-1493
- CONCLUSIONS: Reconstruction of multi-ligament knee injury shows a good outcome than it was left alone. Post-operative physiotherapy increases the potential of reconstruction. While our data is limited because of the rare condition, we plan to expand our study area to include a larger sample size. We also recommend extending the post-operative physiotherapy to improve the outcome of a multi-ligament knee injury.
- Comparison of Bite Force After Administration of Midazolam and Dexmedetomidine for Conscious Sedation in Minor Oral Surgery. [Journal Article]
- JPJ Pharm Bioallied Sci 2019; 11(Suppl 2):S446-S449
- CONCLUSIONS: Dexmedetomidine and midazolam significantly increased the bite force because of the loss of proprioceptive function of periodontal ligament, but there was no significant difference between the drugs regarding bite force.

FEM was technologically innovated which initially aimed at answering structural analysis difficulties involving Mechanics, Civil and Aeronautical Engineering. FEM basically stands for a numerical model of analyzing stresses as well as distortions in the form of any agreed geometry. There for the shape is discretized into the so-called 'finite elements' coupled through nodes. Accuracy of the results is determined by type, planning and total number of elements used for a particular study model. 3-D FE model was designed for in-depth qualitative examination of the relations amongst implant, tooth, periodontal ligament, and bone. Scholarly work equating work reliability, validated with a 3-D modeling suggested that meticulous data can be acquired with respect to stress distribution in bone. Comparative results from 3-D FEA studies showed that 3D FEA, when matched with in-vivo strain gauge measurements were corresponding with clinical outcomes. The aim of this review of literature is to provide an overview to show the application of FEM in (Short) implant dentistry.
- [Research progress of surgical treatment for anterior shoulder dislocation and combined injuries]. [Journal Article]
- ZXZhongguo Xiu Fu Chong Jian Wai Ke Za Zhi 2019 Jun 15; 33(6):768-773
- CONCLUSIONS: With the development of arthroscopy and the improvement of the surgical concept, there is a complete set of surgical options for various injuries of the anterior shoulder dislocation. When choosing a surgical procedure, the patient's specific injury and age, exercise level, and other relating factors should be comprehensively assessed in order to achieve the best results.
