Comparison between the effects of Maitland's mobilization versus its combination with vastus medialis oblique neuromuscular stimulation on two scales (NPRS & WOMAC) in knee osteoarthritis patients.

Background & objectives: Osteoarthritis (OA) is the most common form of arthritis that increases with age affecting the population from the middle age to the elderly. The present study was undertaken to find whether neuromuscular stimulation of vastus medialis oblique (VMO) in combination with Maitland's mobilization and exercises was more effective as compared to Maitland's mobilization with exercises alone in patients with knee OA. Methods: Sixty patients with knee OA were purposively selected and randomly distributed to two groups that received an intervention for eight weeks. Group A patients received Maitland's mobilization in combination with exercises and group B patients received the same intervention as group A in combination with neuromuscular stimulation of VMO muscle. After eight weeks, outcome measures, i.e. Numeric Pain Rating Scale (NPRS) and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) index, were reassessed. Results: Both groups showed significant (P<0.05) within-group improvement in the knee pain levels and stiffness as reflected by NPRS and WOMAC index. Interpretation & conclusions: Patients of both the groups (A and B) were found to be improving significantly in pain and disability, group A patients receiving Maitland's mobilization in combination with exercises were found to get more relief in pain and disability.

Evaluation of Crestal Bone Loss in Flap vs Flapless Implant Placement Technique: An In Vivo Comparative Study.

AIMS: The aims of the study were to assess the technique with-flap and flapless implant placement and to compare crestal bone heights around the implant in flapless and conventional flap technique using digital radiovisiograph, in 3 and 6 months after the surgery. MATERIALS AND METHODS: A total of 20 implants were placed by flap and flapless implant technique; each patient received two implants, except for two patients who received four implants. A radiovisiograph was taken at implant placement, as well as 3- and 6-month intervals. Crestal bone level was compared between flapless and flap during these intervals and compared between intervals for each group. RESULTS: On evaluating the distribution, it was found to be asymmetric and hence lacked normality (K-S = 0.382; p <0.001). On mesial side, bone loss values in group I ranged from 0.40 to 1.10 units with a mean value of 0.71 and a standard deviation of 0.26 units. The median value was 0.70. On evaluating the data for normality, it was found to be symmetric and normal (K-S = 0.166; p = 0.200). CONCLUSION: This study concluded that there are not any significant differences in the crestal bone with both flap and flapless techniques. Comparatively, the flapless approach showed a lesser crestal bone height reduction, which was statistically significant. CLINICAL SIGNIFICANCE: Implant dentistry is nonetheless behind when advances are concerned, we have seen the inclination toward minimal invasive implant techniques to yield better esthetic as well as improved results, thus taking care of patients' discomfort.
