“…Repeatability tests were also performed twice in a 7-day interval in 50 selected patients. To determine the reliability of the instrument, intraclass correlation coefficients (ICC [2,1] ); (two times and one examiner) were calculated. The acceptable level for ICCs was set at > 0.7 [17].…”

“…Meniscal rupture occurs most often in the third, fourth and fifth decades of human life [1], and the mean incidence of meniscal tear is about 60-70 per 100,000. Meniscal arthroscopy is performed for two milion persons annually worldwide, at a cost of several million USD [2,3]. People with chronic meniscal injury are at greater risk of increased loads on the knee cartilagea type of injury that can be associated with knee osteoarthrities.…”

“…People with chronic meniscal injury are at greater risk of increased loads on the knee cartilagea type of injury that can be associated with knee osteoarthrities. In addition, prolonged meniscal pathology can make people unwell in other ways [2,[4][5][6][7]. Previous studies found that neither surgical nor nonsurgical approaches to treat meniscal pathology prevent knee osteoarthritis, although conservative treatments may be more effective in preventing knee osteoarthritis more than partial menisectomy.…”

Background: The Western Ontario Meniscal Evaluation Tool (WOMET) is the only questionnaire available to assess quality of life in patients with isolated meniscal injuries. The aims of this study were to prepare the Persian version of the WOMET (PWOMET) and validate it in Iranian patients with isolated meniscal tears. Methods: In the first stage, the English version of WOMET was translated into Persian. Content validity, and qualitative and quantitative (impact score) face validity were tested by specialists and in a sample of 30 patients. In the second stage, PWOMET was assessed for the evaluation of psychometric properties in 100 patients with isolated meniscal injury and 50 healthy people based on the COSMIN checklist. Construct validity was tested based on structural validity (factor analysis) and hypothesis testing. Correlation with the total scores on the SF-36, IKDC and KOOS were used for concurrent criterion validity. Test-retest reliability and internal consistency were calculated using intraclass correlation coefficient (ICC) and Cronbach's alpha, respectively. In addition the standard error of measurement (SEM) and smallest detectable change were calculated. Interpretability was investigated as the ceiling and floor effects and minimal important difference. Results: The PWOMET had acceptable qualitative face validity and content validity. The impact score (quantitative face validity) was more than 1.5 for all items. For construct validity, structural validity (factor analysis) and hypothesis testing ability were confirmed. Correlations between the PWOMET total score and IKDC, SF-36, KOOS scores were 0.61, 0.54 and 0.63, respectively (p < 0.001), thus confirming concurrent criterion validity. The intraclass correlation coefficient, Cronbach's alpha, SEM and smallest detectable change for the PWOMET were 0.73, 0.89, 9.43 and 26.13, respectively. The PWOMET had no ceiling or floor effects, and minimal important difference was 9.07. Conclusion: The PWOMET provides valid and reliable scores for assessment of the quality of life in patients with isolated meniscal injury.

“…However, the analysis of the published data allows us to conclude that meniscal and chondral lesions may become more prevalent with experience. For example, Beals et al, having analyzed 14 studies on the prevalence of asymptomatic meniscal lesions in adult amateur and professional athletes (mean age 31.2 years), observed such lesions in 31.3% of the participants [40].…”

Background: Currently, no data is available regarding the association between professional experience or limb dominance and the prevalence of asymptomatic knee joint lesions in adult professional male soccer players. Hypothesis: The prevalence of the accumulated changes increases with training experience. This is especially true for the dominant leg, which is involved in a large proportion of the athletes' movements. Study Design: Level 2 cross-sectional cohort study Methods: MRI was used to assess the condition of 94 knee joints in 47 adult professional male soccer players (mean age 25.7 ± 4.6 years, BMI 22.8 ± 1.4). Previous surgery on joints was an exclusion criterion. No football player had knee injuries (including fresh bruises) for at least 3 months before the examination. All the scans were performed using a 1.5T MRI scanner and a slice thickness of 3 mm. The images were blindly analyzed by two experienced radiologists. We analyzed all the three compartments of the knee joint. We consider a chondral lesion already from grade I in modified Noyes and Stabler classification system. To assess the influence of soccer training experience, all players were divided into two groups: group 1 formed from players with less than 20 years of experience and group 2 with more than 20 years of experience. Results: One hundred percent of the soccer players had at least one chondral and meniscal lesion. In both legs, the posterior horn of the medial meniscus (95.6%) was the most frequent site of injury. Most of the injuries were classified as grade II injuries (73.3% for the dominant and 75.6% for the non-dominant leg). Experience and age of the athletes significantly increased the probability of subcortical bone lesions. They were significantly positively correlated with the grades of patellar lesions and lesions of the patellar surface of the femur

“…Among the published literature were 2 reviews analyzing the prevalence of asymptomatic changes of the knee joint in athletes of different performance levels. Beals et al 3 summarized the results of 14 studies on the prevalence of asymptomatic meniscal injuries in amateur and professional athletes (N ¼ 295; mean age, 31.2 years) and found changes of meniscal tissue in 31.1% of the participants. A study by Flanigan et al 8 analyzed 11 studies (N ¼ 931) on the prevalence of changes in tissue of menisci and cartilages in groups of adult elite athletes.…”

Background: Currently, there are few data on the association between participation in soccer and the condition of the knee joints in adult professional players. Hypothesis: A high percentage of professional soccer players will have asymptomatic intra-articular changes of the knee. Study Design: Cross-sectional study; Level of evidence, 3. Methods: The condition of the intra-articular structures (osteophytes, cartilage, and menisci) in 94 knee joints of 47 adult professional soccer players (mean ± SD age, 25.7 ± 4.6 years; body mass index, 22.8 ± 1.4 kg/m2) was analyzed. A 1.5-T magnetic resonance imaging scanner was used to perform the imaging, and the anonymized data were analyzed by 2 experienced radiologists. Results: Cartilage of both knee joints was affected in 97.9% of soccer players. Meniscal lesions were detected in 97.8% of joints, affecting both joints in 93.6% of athletes. Grade 2 cartilage lesions were the most prevalent (36%-60% depending on the lesion site), and grade 4 lesions were detected in 12.7% of joints. The medial femoral condyle and medial tibial plateau were most frequently affected by cartilage lesions (85.1%). Among meniscal lesions, grade 2 lesions were the most prevalent, being detected in 71% of the cases. Grade 3 lesions were detected in 13.8% of the joints. The posterior horn of the lateral meniscus was the most common site of meniscal lesions (affected in 95.7% of the joints). Osteophytes were detected in 4.2% of joints. Conclusion: The prevalence of asymptomatic cartilage and meniscal lesions in the knees of adult professional soccer players is extremely high and is not associated with the reduction of sports involvement. This research should promote the correct interpretation of magnetic resonance imaging data obtained from soccer players with acute trauma and the reduction of the number of unwarranted surgical procedures.

The Prevalence of Meniscal Pathology in Asymptomatic Athletes

Abstract: The overall prevalence of isolated meniscal pathology in asymptomatic athletes was 31.1 % (27.2 % with intrasubstance meniscal damage and 3.9 % with a meniscal tear). More studies of age-comparable, non-athletic populations are necessary for direct comparison with these groups.
