Knee pain and postural stability in women with gonarthrosis before and six months after unilateral total knee replacement

Abstract

The aim of this study was to investigate knee pain and postural stability in women with knee osteoarthritis (OA), who used postoperative home exercise program (HEP) with balance exercises. 14 women with knee OA in stage III-IV (aged 48-70 years) participated in this study before and 6 months after unilateral total knee arthroplasty (TKA). All patients performed HEP during 6 months after unilateral TKA. Data of patients was compared with healthy age-matched women (controls, n=10). Postural stability characteristics (centre of pressure (COP) displacement in the anterior-posterior (AP) and mediolateral (ML) direction, COP sway equivalent radius and area) during 30 s bipedal standing (eyes open) were recorded on two dynamographic force plates. Pain in knee joint was estimated with visual-analogue scale. COP displacement in AP direction of the operated and non-operated leg was greater (p<0.05) in women with knee OA before and 6 months after TKA compared to the controls. Knee joint pain in the operated leg reduced 70% after TKA. TKA together with HEP has an important role in preserving postural stability and reducing knee joint pain in women with III-IV stage gonarthrosis.

Pre-surgery exercise and post-operative physical function of people undergoing knee replacement surgery: A systematic review and meta-analysis of randomized controlled trials

“…Full recovery of muscle strength and physical function to a normal level is rare (10,12) and impairments may persist several years after surgery (17)(18)(19)(20). In addition, these impairments can lead to reduced balance and movement control (21,22) and a greater risk of falling (22,23). Neuromuscular performance capabilities are altered significantly in people with arthritis, and impairments are evident pre-operatively (24).…”

Quadriceps Strength, Postural Stability, and Pain Mediation in Bilateral Knee Osteoarthritis: A Comparative Analysis with Healthy Controls

“…These findings are in agreement with previous research. A study by Rätsepsoo et al [56] found a significant association between quadriceps strength and postural stability in individuals with knee OA. Similarly, a study by Hinman et al [57] reported a relationship between muscle strength and functional performance in individuals with knee OA.…”

Prophylaxis of knee joint contractures after primary knee replacement with kinesiotherapy (metaanalysis and literature review)

“…Снижение силы четырехглавой мышцы бедра оказывает существенное влияние на изменение статического и динамического постурального баланса [17,45] и повышает риск падения пациентов [45]. Это, в свою очередь, потенцирует увеличение частоты неблагоприятных результатов эндопротезирования коленного сустава.…”
