“…In addition women are more susceptible to obesity than men which are another important risk factor for OA. This is consistent with previous reports of Sudo, et al, (2008) and Sanjeev, & Michael, (2012) who revealed that knee OA was more common among females than males.Concerning the level of education, the present study revealed that post/secondary was prevailing among less than half of the patients, this finding in the same line with Kim et al, (2010) who stated that knee OA is significantly greater with a good level of education. Also this is in agreement with The Center for Disease Control and Prevention (CDC, 2010) which reported that the incidence of knee OA in people with high education more than in people of illiteracy.…”

“…They include obesity (high BMI) [14,15], gender (female) [14], aging [14,16], previous knee trauma [14], occupational kneeling or squatting [15,17] and a higher BMD [18][19][20] Knee pain defined as: − absent, + one sided, ++ bilateral OA osteoarthritis, CI confidence interval, BMI body mass index, ROM range of movement and previous knee trauma in Japan have also been reported as risk factors [2,21,22]. Our previous crosssectional study [5] also found that a higher BMI, female gender, more advanced age and a higher BMD were significantly associated with an increased risk of radiographic knee OA. This longitudinal study showed that gender and obesity were risk factors for the incidence of knee OA, whereas aging was not.…”

“…The risk factors for progressive knee OA reported by Felson et al [8] are obesity, not smoking and weight gain, whereas those reported by Cooper et al [13] are obesity, knee pain and Heberden's nodes. Felson et al [5] reported that smoking favourably affects rates of other diseases, such as inflammatory bowel disease, and one of the many constituents of smoke might inhibit cartilage destruction. However, this finding is not universal and smoking did not affect the progression of knee OA in our study.…”

This longitudinal study aimed to identify risk factors for the incidence and progression of radiographic knee osteoarthritis (OA). We examined the inhabitants of Miyagawa village aged ≥65 years every two years between 1997 and 2007. Anteroposterior radiographs of both knees were graded for OA using the Kellgren-Lawrence (K/L) grading system. Knee OA was defined as grade ≥2. We recorded the incidence of knee OA among participants in whom both knees changed from K/L grades 0 or 1 to ≥2 over a four-year follow-up period. We also recorded the progression of knee OA using this threshold among patients in whom one or both knees changed from K/L grades 2 or 3 to any higher grade over the follow-up period. Baseline data obtained from standard questionnaires, physical findings and X-rays included age, gender, body mass index (BMI), osteoporosis, Heberden's nodes, knee range of motion (ROM), knee pain and cigarette smoking. The rates of incidence and progression of knee OA among 360 participants (241 women, 119 men) who fulfilled the study criteria were 4.0 and 6.0% per year, respectively. Female gender (odds ratio [OR] 2.849, 95% confidence interval [CI] 1.170-6.944) and high BMI (OR 1.243, 95% CI 1.095-1.411) were significantly associated with the incidence of knee OA, and restricted knee ROM (OR 0.941, 95% CI 0.892-0.992) was significantly associated with knee OA progression. Patients with a low knee ROM relative to grade of radiographic knee OA require more careful follow-up than those with a higher ROM.

“…Although people at risk of developing this condition are known to include the elderly, women, people with obesity, people with a history of knee injury, and people with a knee varus deformity, the underlying causes are still unknown [1][2][3]. Onset typically occurs after reaching 40 years of age, and it is clear that the prevalence increases sharply in people aged 50 and above [4][5][6].…”

Transparent 3D images was used to analyze the motion of the patella in knee extension movements at the patellofemoral joint in asymptomatic persons aged 40 and over who are at increased risk of osteoarthritis of the knee.By adding transparency to 3D images constructed by extracting the femoral condyle cartilage and patella from 3D data using MRI scans at knee flexion angles of 120°, 90° and 60°, the patella movement analysis images allow the position of the patella to be accurately ascertained through the joint cartilage. This made it possible to analyze the rotation and inclination of the patella when the patella is moved by the femoral trochlear during knee extension movements.There was a correlation between patella rotation and patella inclination when the knee is extended. 3D motion analysis of the patella at the patellofemoral joint was performed by complex computer analysis according to conventional methods. Transparent 3D imaging facilitates the use of bony landmarks to analyze the motion of the patella. This method is thought to be useful in preventive medicine by enabling early prognostic prediction by performing motion analysis of the patella with respect to deformation of the patellofemoral joint.
