Background: In today’s life style, the gap between athletic activities and daily life activities is becoming wider. The daily life routine is becoming sedentary due to technology and sports activities and thus require high level of physical performance. Knee joint is the most vulnerable to rapid forces and injuries, in which meniscal injury is quite noticeable. Objective: To determine the mechanism of meniscal injury and its impact on performance in athletes after knee meniscal injury. Methods: After taking approval from ethical committee, consent was taken from the athletes prior to filling out the forms. The study was conducted on 145 male athletes in Lahore, aged between 17 to 40 years. Data was collected through international knee documentation committee subjective knee form which consisted of demographical data and questions which were divided into three sections; symptoms, sports activities and knee functions. Results: The main results regarding the mechanism of meniscal injury showed that there were 29% athletes having insidious tear, 16.6% acute noncontact, 32.4% contact with player and 22.1% non-specific mechanism of tear. The mean and standard deviation of total international knee documentation committee score was found to be 66.64±3.83, reflecting a moderately affected level of performance. Conclusion: The findings concluded that the common mechanism of meniscal injury was during contact with player or defense strategy during activity. The athletic performance level due to meniscal injury was moderately affected.
Background: Prolonged sitting and standing raise the load on the knee, thus increasing the risk of knee pain and severity among teachers. Objective: To determine the association of knee pain in long-standing and sitting among school and university teachers. Methods: It was a cross-sectional survey conducted on 185 patients with a history of chronic knee pain. The data was collected from school and university teachers in the private and public sectors. Data were collected from both male and female teachers having knee pain and aged between 27 to 60 years and the patients who have a history of knee osteoarthritis, carcinoma, traumatic injury and wound/infection were excluded from the survey. The categorical variables were evaluated by frequency and percentages, while mean and standard deviation were calculated for continuous variables. The correlation was calculated between knee pain reported by university professors due to long periods of standing or sitting. Results: Out of 185 participants, 111 (60%) were females and 74 (40%) were males, with a mean age of 41.37±11.33. There was a weak positive correlation between knee pain and standing hours, which was statistically significant (r=0.273, n =185, p<0.001). There was a negative correlation between knee pain and sitting hours, (r=-0.160, n=185, p<0.05). Conclusion: This study found that prolonged standing hours may increase knee pain among teachers as compared to prolonged sitting. More standing hours during academic activities tend to increase knee pain while prolonged sitting did not increase that pain. There was a negative correlation between knee pain and sitting hours, and weak positive correlation between knee pain and standing hours, which was statistically significant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
