BACKGROUND Sports activities were thought to be the major cause of meniscus injury in both men and woman, but our observations of non-athletic females show that the cause of meniscus injury was unrelated to any type of sports activity. OBJECTIVES This study revealed squat winnowing to be a major cause of meniscus injury in non-athletic females. PATIENTS AND METHODS This retrospective study ...

With increasing life expectancy, the demand for preservation of native articular cartilage is increasing to delay joint arthroplasties. In the knee, there are many different strategies to preserve the articular cartilage including but not limited to corrective osteotomies, chondral injury restoration, intraarticular injection of cells or growth factors(PRP). However, One of the most important s...

BACKGROUND The purpose of this study was to determine the epidemiology and history of knee injury and its impact on activity limitation among football premier league professional referees in Iran. METHODS This was a descriptive study. 59 Football Premier League professional referees participated in the study. The knee injury related information such as injury history and mechanism was recorde...

OBJECTIVE The purpose of this study was to assess the relationship between the presence of meniscal injury and the femorotibial angle in the knee joint. METHODS Patients who underwent knee magnetic resonance imaging (MRI) at our department between January 2015 and March 2015 were included in this study. Knee MR images of these patients were retrospectively re-evaluated for meniscal injury. Th...

the arthroscopic study of knee joint is of outstanding interest in assessment of knee complaints. the present article describes the results of arthroscopic examination of 100 patients (mean age 29.4 years 82% male) evaluated from 1996 to 1997 in imam khomeini hospital of tehran. sport injury was the most prevalent cause of referral (40%). the 2 most frequent complaints were knee pain (94%) and ...

The mechanisms of anterior cruciate ligament (ACL) injuries are still inconclusive from an epidemiological standpoint. An epidemiological approach in a large sample group over an appropriate period of years will be necessary to enhance the current knowledge of the ACL injury mechanism. The objective of the study was to investigate the ACL injury occurrence in a large sample over twenty years an...

UNLABELLED PURPOSE The purpose of this present study was to examine contralateral ACL injury cases after ACL reconstruction, to determine the characteristics of such injuries. METHODS We performed a retrospective analysis of 24 patients with contralateral ACL injury after ACL reconstruction. The control group consisted of 200 cases with unilateral ACL injury. The following were examined in...

This article describes a traumatic complete anterior knee dislocation of a previously well-functioning total knee arthroplasty. A thorough physical examination with appropriate radiographic imaging study is required for proper evaluation and treatment of this injury, as it is often associated with neurovascular injury and subsequent global instability of the injured knee is likely.

Knee dislocation is an uncommon, potentially limb-threatening, knee injury. Most often caused by high-velocity trauma, it can also result from low- or even ultra-low-velocity trauma. Rapid identification of the injury, reduction, and definitive management are necessary to minimize neurovascular damage. We present a case of rotatory anterolateral knee dislocation sustained during a twisting spor...

OBJECTIVE To clarify the determinants of dynamic knee stability early after anterior cruciate ligament injury. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 1. METHODS Three hundred forty-five consecutive patients who were regular participants in International Knee Documentation Committee level I/II sports before injury and had an acute isolated anterior cruciate ligament injury...
