“…Further, previous findings of changes in gait patterns (3,24) and coactivation/elongation of the hamstrings (25) suggest that KOA may not only affect the quadriceps, but also other thigh muscles, specifically the hamstrings. Some studies also reported flexor strength (1) and/or the extensor:flexor strength ratio to be reduced in osteoarthritic knees (26).…”

Objective. To determine whether thigh muscle strength differs between symptomatic and asymptomatic knees, and/or different radiographic strata of knee osteoarthritis (KOA). Results. Isometric strength was significantly lower in symptomatic than in asymptomatic legs: ؊11 to ؊13% for extensor strength and ؊7 to ؊16% for flexor strength (P < 0.0001 for both) in men, and ؊9 to ؊17% (P ‫؍‬ 0.029) for extensor strength, and ؊10 to ؊21% (P ‫؍‬ 0.049) for flexor strength in women. Similar observations were made for pain frequency strata. Extensor and flexor strength were not significantly different across K/L grade strata in asymptomatic legs in either sex (P > 0.12). However, strength normalized to body weight was lower at higher K/L grades in both sexes (P < 0.02) because the body mass index was greater in participants with more advanced radiographic disease. Conclusion. Knee symptoms (i.e., pain) appear to be the relevant determinant of isometric knee extensor and flexor strength in KOA, whereas no direct association between strength and radiographic severity was observed. These findings suggest that the reduction in thigh muscle strength in KOA is related to pain but not to the structural (radiographic) disease status.

“…Хотя непродолжительного уменьшения массы тела можно добиться с помощью диеты и физической нагрузки, сохранить полученный результат в течение длительного времени не удается большинству людей [96]. До 75% паци-ентов, соблюдающих диету (особенно очень низкокало-рийную -около 400-800 ккал/сут), набирают большую часть от потерянного в течение 1 года [55,80].…”

В обзоре освещены проблемы влияния ожирения на развитие, прогрессирование, тяжесть остеоартроза (ОА), обсуждаются методы лечения ожирения при этом заболевании. Показано, что снижение массы тела у пациентов с ожирением и ОА ведет к уменьшению клинических проявлений. Несмотря на множество про-веденных исследований по влиянию немедикаментозной терапии ожирения у больных ОА (диета, физиче-ская активность), результаты остаются противоречивыми и требуют дальнейшего изучения. Ключевые слова: остеоартроз; ожирение. Для ссылки: Стребкова ЕА, Алексеева ЛИ. Остеоартроз и ожирение. Научно-практическая ревматология. 2015;53(5):542-52. OSTEOARTHRITIS AND OBESITYStrebkova E.A., Alekseeva L.I.The review highlights the impact of obesity on the development, progression, and severity of osteoarthritis (OA) and discusses treatments for obesity in this disease. Weight loss in obese patients with OA is shown to lead to a reduction in clinical manifestations. Despite a great deal of performed investigations of the impact of non-drug therapy for obesity (diet, physical activity), their results are contradictory and call for further investigation.

“…Low muscle strength and power is associated with patients' poor mobility [17] and decreased knee range of motion (ROM) affect patients' ambulation function [32]. According to this the gait parameters are affected in patients with knee OA before and after total knee arthroplasty (TKA) [13].…”

On patients with knee osteoarthritis (OA) the muscle strength, gait and everyday activities performance capacity decreased, though patients care started many years before. Patients care includes supervised physio therapy sessions and home exercise performing. Research goal was to assess the improvement in patients with knee OA motor performance with home exercise program (HEP) 8-weeks before total knee arthroplasty (TKA). Hypothesis: 8-week HEP improve legs motor performance in patients with knee OA. Ten female patients with knee OA with the mean (±SE) age of 62.7±2.3 yrs; ten age-and gender-matched healthy controls with the mean (±SE) age of 62.6±1.1 yrs. Motor performance was assessed by isometric strength of the quadriceps femoris (QF) and hamstring (HM) muscles, gait, Five-Time-Sit-to-Stand (FTSTS) test and knee active range of motion (aROM) before and after 8-week HEP. Outcome was measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). After 8-week HEP, QF and HM isometric strength, knee aROM during flexion and the gait stride length for the involved leg increased (p<0.05) compared to pre-exercising level. The WOMAC score increased and FTSTS test time shortened (p<0.05) after 8-week HEP. Difference in measured parameters between the patients involved leg decreased as compared to uninvolved leg and controls. Study showed that after 8-week HEP improved involved leg thigh's muscle strength, knee aROM, and stride length.

In conclusion, HEP with at least 8 weeks should be recommended for patients with knee OA before TKA.

Body mass index affects knee joint mechanics during gait differently with and without moderate knee osteoarthritis

Abstract: Our results suggest that increased BMI is associated with different changes in biomechanical patterns of the knee joint during gait depending on the presence of moderate knee OA.
