چکیده:
The purpose of this study was to compare the severity of osteoarthritis and knee pain, movement difficulties, and quality of life related to knee osteoarthritis in veteran endurance runners and non-athletes. In this study, 26 male subjects were purposefully selected and divided into two equal groups of thirteen. Diagnosis of the disease was confirmed by an orthopedic specialist through clinical signs based on the American College of Radiology diagnostic criteria, as well as clinical assessment using the Lequesne’s pain and function index for knee osteoarthritis. Then, the global and localized questionnaire of outcomes of osteoarthritis and knee injuries (KOOS) was used to measure the research variables. Independent t-test with an error rate of α ≤ 0.05 was used for data analysis. Despite a higher average severity of knee osteoarthritis by 5.5% (P=86.0%), the severity of knee pain by 69.4% (P=40.0%), the amount of difficulty in performing daily activities by 52.3% (P=83.0%), the amount of difficulty in performing sports-recreational activities by 10.35% (P=97.0%), and quality of life by 82.3% (P=48.0%) in veteran endurance runners compared to non-athletes, no significant difference was observed between the two groups. Therefore, it is concluded that endurance running at a competitive level does not significantly increase the risk of developing knee osteoarthritis and related problems in veteran endurance runners compared to non-athletes; so that endurance at a competitive level cannot be a risk factor for knee joint erosion.

Assistant Professor, Department of Physical Education, Payam Noor University of Tehran, Iran Abstract The aim of this study was to compare the severity of osteoarthritis and knee pain, movement difficulties, and quality of life related to knee osteoarthritis in veteran endurance runners and non-athlete individuals.
Therefore, it is concluded that endurance running at a competitive level does not significantly increase the risk of developing knee osteoarthritis and related problems in veteran endurance runners compared to non-athlete individuals; so that endurance at a competitive level cannot be a risk factor for knee joint erosion.
In contrast, researchers such as Chakravarty7 and colleagues (2008), Hohmann8 and colleagues (2004), Konradsen9 and colleagues (1990), Lane10 and colleagues (1986-1998), Van Ginckel11 and colleagues (2010), Wijayaratne12 and colleagues (2008) and also Ward13 and colleagues (1995) showed no significant association between endurance running and increased severity of knee osteoarthritis.
Comparison of Osteoarthritis Severity and Knee Pain, Movement Difficulties in Daily Activities, Sports, Recreational Activities, and Quality of Life in the Runner and Non-Athlete Groups and the Results of the t-test (Refer to the image on the page) Continuation of Table 2.
The results of the present study show that despite the lack of significant difference, the conditions in terms of knee osteoarthritis are more severe in endurance runners compared to non-athletes (control group).
Based on the research findings, despite the worse conditions in veteran endurance runners compared to non-athletes, considering the non-significance of the results, it can be concluded that endurance running at the championship level does not increase the risk of developing knee osteoarthritis and problems 1.
