The effectiveness of an exercise programme on knee loading, muscle co-contraction, and pain in patients with medial knee osteoarthritis: A pilot study

Introduction: Alteration of foot posture may influence the knee loading, particularly in medial compartment. The purpose of this study was to find the relation of foot postures with clinical finding in medial knee osteoarthritis (KOA).Methods: Subjects with medial KOA who met inclusion criteria were recruited consecutively, in Nursing home on August to October 2018. The foot posture has determined by Foot Posture Index (FPI). The severity of KOA has measured by Kelgreen-Lawrence (KL) grading system, and pain level using numeric rating score (NRS).Results: There were 37 subjects consisted of male and female with normal foot subsequently 17(8.5%) and 3(15%), male and female with abnormal food subsequently 3(15%) and 1(16%). There were 12 (32.43%) of pronated foot, 5 (13.51%) of supinated foot, and 20 (54.06%) of normal foot subjects. The subjects with abnormal foot posture have severe medial KOA (p<0.001), while the pain sensation similar between groups (p=0.321, p=0.688).Conclusion: There was a correlation between foot posture and the severity of medial KOA.Keywords: Foot posture, Knee osteoarthritis, Foot posture index, Numeric rating score

Contact Pressures

Medial knee loading during stair negotiation in individuals with medial knee osteoarthritis has only been reported in terms of joint moments, which may underestimate the knee loading. This study assessed knee contact forces (KCF) and contact pressures during different stair negotiation strategies. Motion analysis was performed in 5 individuals with medial knee osteoarthritis (52.8 [11.0] y) and 8 healthy subjects (51.0 [13.4] y) while ascending and descending a staircase. KCF and contact pressures were calculated using a multibody knee model while performing step-over-step at controlled and self-selected speed, and step-by-step strategies. At controlled speed, individuals with osteoarthritis showed decreased peak KCF during stair ascent but not during stair descent. Osteoarthritis patients showed higher trunk rotations in frontal and sagittal planes than controls. At lower self-selected speed, patients also presented reduced medial KCF during stair descent. While performing step-by-step, medial contact pressures decreased in osteoarthritis patients during stair descent. Osteoarthritis patients reduced their speed and increased trunk flexion and lean angles to reduce KCF during stair ascent. These trunk changes were less safe during stair descent where a reduced speed was more effective. Individuals should be recommended to use step-over-step during stair ascent and step-by-step during stair descent to reduce medial KCF.
