Background:Anterior cruciate ligament injuries commonly occur during sports that involve sudden stops or direction changes. Although athletes often use arch-support insoles in competition and training, little is known about the effect of foot insoles on knee biomechanics and jump take-off performances.Objective:This study aimed to investigate the effects of arch-support insoles on knee kinematics and kinetics during the stop-braking phase and the subsequent jump take-off performances.Study design:That is a quasi-experimental study, repeated-measures design.Methods:Twenty male healthy recreational university basketball athletes performed stop-jump with maximum effort in both arch-support and flat insole conditions. Paired t-tests were performed on knee kinetics and kinematics and jump performance variables to determine whether there were significant differences between insole conditions.Results:Wearing arch-support insoles experienced larger ground reaction forces (GRFs), loading rates of peak vertical and posterior GRFs, peak knee adduction and rotation moments, and knee flexion angular velocity than the flat insoles (P < 0.05).Conclusions:The increased GRFs and knee loading in arch-support insoles are indicative of a higher risk of anterior cruciate ligament injuries. The findings could be insightful to the knee mechanics that are related to performance and injury potential during stop-jump maneuvers.

“…These results suggest that the lateral thrust is independent on DMME in a severe case. Some studies report an increase in MME when going from a non-weight-bearing to a weight-bearing condition [12,13,20]. However, Patel et al reported the effect of OA severity on meniscus extrusion during weight bearing.…”

“…1). MME was quantified as the distance from the medial tibial plateau cortex to the outermost edge of the medial meniscus, based on previous studies [12,20], and it was measured using image processing software (Image J ver19, NIH, US). MME was measured in two conditions: non-weightbearing (supine) and weight-bearing (unipedal standing).…”

Background: Lateral thrust is known to be risk factors for knee osteoarthritis progression. Medial meniscus extrusion is also known to be risk factors for knee osteoarthritis progression; moreover, the amount of change in medial meniscus extrusion from non-weight bearing to weight bearing is an important factor for the progression of knee osteoarthritis. This study aimed to investigate the correlation between lateral thrust and the change in medial meniscus extrusion. Methods: In total, 44 knees from 44 patients (mean age, 68.9 years) with knee osteoarthritis were divided into two groups according to the KellgreneLawrence grade: early-stage osteoarthritis (Kellgren eLawrence ¼ 2) and severe osteoarthritis (KellgreneLawrence ¼ 3 or 4). The lateral thrust during gait, represented as the lateral acceleration peak immediately after heel strike, was recorded by an inertial sensor. The amount of change in medial meniscus extrusion, which was the difference between weightbearing (unipedal standing) and non-weight-bearing (supine) conditions, was evaluated using ultrasonography. Results: The mean value of the lateral acceleration peak in the severe osteoarthritis group was higher than that of the early-stage osteoarthritis group (p < 0.05). The non-weight-bearing and weight-bearing medial meniscus extrusion in the severe OA group were significantly higher than those of the early-stage osteoarthritis group (p < 0.001). However, the amount of change in medial meniscus extrusion in severe osteoarthritis group was significantly lower than in the early-stage osteoarthritis group (p < 0.05). The amount of change in medial meniscus extrusion showed a significant correlation with the lateral acceleration peak in the early-stage osteoarthritis group (r ¼ 0.56, p < 0.001). On the other hand, there was no significant correlation in the severe osteoarthritis group. Conclusion: The lateral thrust shows a positive correlation with the amount of change in medial meniscus extrusion by weight bearing in patients with early-stage knee osteoarthritis.

“…Use of the wedge insole, as is a nonoperative approach, is used for the treatment of knee osteoarthritis in clinical practice, because it can decrease the loading stress of knee compartment. [18] Besides, the wedge insole can significantly increase femorotibial angle, which means reduce the knee varus deformity. [8] However, Maly et al's study have shown no association with between severity of pain and knee load.…”

Background:Functional limitations and pain are common presenting complaints for people suffering from knee osteoarthritis. Wedge insole can be sued for treatment of knee osteoarthritis. Hence, we conducted a systematic review and meta-analysis to explicit the efficacy of wedge insole in the treatment of knee osteoarthritis.Methods:A systematic literature search for studies will be performed in MEDLINE, Embase, the Chinese National Knowledge Infrastructure Database (CNKI), Cochrane Library, Web of Science. The methodological quality of the included studies using the risk bias assessment tool of Cochrane. Funnel plot will be used to assess the reporting bias. And the level of evidence for results are assessed by the GRADE method. Statistical analysis is conducted with Revman 5.3.Results:This systematic review and meta-analysis will provide a synthesis of evidences for wedge insole on knee osteoarthritis.Conclusion:The conclusion of this study will provide recommendations to assess effectiveness of exercise on knee osteoarthritis, which may further guide clinical practice.PROSPERO registration number:CRD42018096804
