Relationship of Patellofemoral Angles and Tibiofemoral Rotational Angles With Jumper's Knee in Professional Dancers: An MRI Analysis.

Background: Jumper's knee is a type of tendinopathy affecting the distal insertion of the quadriceps tendon (25% of cases) or the patellar tendon. It has been shown that frontal-plane measurements, such as genu valgum, genu varum, an increased quadriceps angle, a protuberant tibial tuberosity, patella alta, and short hamstring muscles, may be related to jumper's knee.

Purpose: To investigate the effects of tibiofemoral rotational angles and patellofemoral (PF) angles on the development of jumper's knee in professional folk dancers.

Patellofemoral Chondropathy Areas in Folk Dancers: An MRI Study.

Background: Patellofemoral chondropathy (PFC) is one of the most important causes of patellofemoral pain syndrome. PFC may occur as a result of anatomic reasons such as patellar malalignment and/or increased patellofemoral joint stresses. Most research on this subject has involved sports injuries and anatomic variations.

Traumatic knee injury patterns in Anatolian folk dancers: a case series and literature review.

Lower extremities, especially the knee region, are susceptible to traumatic injuries because of long-lasting hard landings and impacts. Most of the injuries described in the literature are associated with ballet. In this review study, the authors tried to present the traumatic knee injury patterns of the Anatolian folk dance.

Relationship of Popliteus Sulcus Depth and Tibiofemoral Rotational Alignment with Popliteus Tendinitis in Professional Folk Dancers Exposed to Turnout Positions: An MRI Analysis.

Aims: The popliteus musculotendinous unit plays the major role in range of motion, rotation and stabilization of the knee. Frequent repetition of the rotational strains such as turnout in dancers may be the cause of popliteus tendinitis. In addition, popliteus sulcus depth (PSD) and PSD/lateral condyle width (LCW) ratio are also highly related with popliteal tendinitis in professional folk dancers.

Overuse Injuries in Professional Anatolian Folk Dancers: A Descriptive Study Verified with MRI.

Background: Professional dancers are artists as well as athletes who push their bodies beyond limits for aesthetic expression. Therefore, overuse injuries are common. We present our findings on overuse injuries in Anatolian (Turkish) folk dancers.

Radiographic and pathological stages of the changes at the bone-cement interface: an in-vivo experimental study.

Introduction: Chemical and physical effects of cementation cause radiographic and histological changes at bone-cement interface. These changes can be of interest in the assessment of the residual lesions and subsequent recurrences after local resection and cementation of local aggressive tumours.

Aim: The aim of the study was to evaluate the evolution and determine the stages of the changes that occur at the bone-cement interface after cementation of cavitary lesions.

[Hot saline irrigation as an alternative local adjuvant therapy in local aggressive bone tumors].

Objectives: This study aimed to develop an alternative thermoinactivation method for biological inactivation of microscopic contamination on the cavity wall following curettage of local aggressive tumors. Hot saline irrigation was applied at various temperatures to bone cavity, with or without tourniquet on the extremity and temperature changes and local effects were investigated in vivo.

Methods: Bone cavities 12 cm3 in size were created in the condylar regions of the hind legs in nine female adult sheep.

[Comparison of temperature increments in bone cavities induced by methylmethacrylate and heated saline solution].

Objectives: We administered saline solution at 70 degrees C and methylmethacrylate to varying volumes of bone cavities and compared temperature changes produced in bone regions at varying distances to the cavity wall.

Methods: We created varying sizes of cavities in the femoral heads of 20 human cadavers (6, 10, 12, and 20 cubic centimeters) and in the knee region of a human cadaver (6, 10, 12, 20, 30, and 40 cubic centimeters). Initially, saline solution at 70 degrees C was administered to all the cavities for 15 minutes by a pulse-irrigation method, during which temperature changes induced within the bone cavity and at specific distances (1, 2, 3, and 10 mm) to the cavity wall were recorded.
