Background:Osteochondral injuries constitute an entity that is widespread and can be seen in patients of all ages. Actual treatment modalities aim to relieve pain, obtain full range of movement of the joint, and improve the quality of life. There are many slow-acting chondroprotective agents prevalently used in the United States that are classified as nutritional support but not as medicines . This study presents the importance of clinical adverse effect profiles as well as the pharmacological mechanism of action and application of combinations of drugs that are widely prescribed and not subjected to control.Methods:Electronic databases were searched with keywords about the chondroprotective drugs without any language restriction. Evaluations of the descriptive statistics were represented via Microsoft Office Excel 2010 lists in the form of a mean±standard deviation or frequency (%). The first evaluation showed that 1502 studies were potentially relevant. Following exclusion of the 1277 studies which were not clinical, full versions of the remaining 225 studies were subjected to further evaluation. No controlled, blinded, randomized and/or comparative studies met the inclusion criteria of the study, and no studies evaluated the comparative clinical results of the hyaluronan of different molecular weights.Results:The findings of this study concluded that especially when prescribing drugs with ingredients like GS and CS, many patients’ pre-existing conditions must be considered, such as whether the patient has a glucose intolerance or not. Additionally, mineral toxication should be considered since the drugs contain minerals, and after the application of injected hyaluronan, complications should be considered.Conclusion:Clinical, controlled and comparative studies about the use of chondroprotective drugs must be performed to define the benefits of these drugs, if any, in order to determine the most suitable time for operative intervention.

The largest articulation inside human body is the knee joint which is composed by hard components, soft tissues and surrounded muscles. The knee is a mobile hinge, and it permits flexion, extension, slight internal and external rotation of the leg. The knee joint is vulnerable to both sharp injury and chronic osteoarthritis. Once have been injured, the knee joint is not easily restored. This study employs separately the experimental measurement, reverse engineering and finite element analysis to investigate the dynamic characteristics of intricate knee joint. The three-dimensional geometric model of each component of knee joint includes hard tissues and soft tissues. The hard tissues have femur, tibia, fibula, patella and the soft tissues have meniscus, patellar ligament, medial and lateral collateral ligament, a pair of cruciate ligaments, etc. Then the model is imported into ANSYS software. Via modal, periodic excitation and impact analysis, the dynamic characteristics of each component and the whole knee model are received. The fundamental mode shapes, natural frequencies and stresses of all the components of knee are also obtained. These normal modes are essential when investigating the dynamic motion of the whole knee. The results show that after impact, the soft tissues have larger displacement than that of the hard tissues. Consequently, the fracture occurs when the stretch which is caused by external force excess ultimate strength of the component. It also explains why the athletes frequently injure the ligaments and tendons of the knee or ankle during the intensive exercise. Therefore, by reducing the motion of articulation, the professional player could not only reduce the generated internal stresses in the tissue but also consequently lessen the chance of injury.

Background: Patellofemoral Pain Syndrome (PFPS) is one of the most common orthopedic knee conditions encountered in athletes and general population and is more prevalent in females than in males. Lower limb malalignment is an important etiological factor for PFPS. Aim of the Study:The purpose of this study was to determine if there was any relationship between static lower extremity alignment and PFPS.Patients and Methods: Forty nine patients (38 females and 11 males) diagnosed as PFPS had participated in this study with age ranged from eighteen to thirty five years. Each patient was assessed for static lower limb alignment measures (pelvic tilting angle, tibial torsion using PALM (PALpation meter); femoral neck anteversion using inclinometer; Q-angle, tibiofemoral angle using plastic standard goniometer and navicular drop using ruler) and patellofemoral pain by kujala scale. Results:The results showed no relationship between lower limb alignment measures and PFPS Pelvic angle (ρ =0.03, p=0.839), Tibial torsion (ρ =0.145, p=0.319), Q-angle (ρ = 0.074, p=0.612), Tibiofemoral angle ( ρ =0.051, p=0.729), FNA (ρ =-0.144, p=0.436), Navicular drop (ρ=0.03, p=0.836). Conclusion:Lower extremity malalignment does not affect pain and function in patients with PFPS.
