Hip arthroscopy is now commonly used to treat hip pain and pathology, including osteoarthritis (OA). Despite this, little is known about the effect of hip arthroscopy on outcomes of pain and function and progression to total hip arthroplasty (THA) in hip OA. This systematic review aimed to (1) determine pain and function outcomes after hip arthroscopy in people with hip OA; (2) compare the outcome after hip arthroscopy between people with and without hip OA; and (3) report the likelihood of progression to THA in patients with hip OA after hip arthroscopy. This review was conducted in accordance with the PRISMA statement. The Downs and Black checklist was used for quality appraisal. Studies scoring positively on at least 50% of items were included in final analyses. Standardized mean differences (SMDs) were calculated where possible or study conclusions are presented. Twenty-two studies were included in the final analyses. Methodological quality and followup time varied widely. Moderate to large SMDs were reported for people with and without hip OA; however, the positive effects of the intervention were smaller for people with hip OA. Greater severity of hip OA and older age each predicted more rapid progression to THA. Patients with hip OA report positive outcomes from hip arthroscopy, although observed positive effects may be inflated as a result of methodological limitations of the included studies. Patients with hip OA had inferior results compared with those who did not. Chondropathy severity and patient age were associated with a higher risk and more rapid progression to THA. High-quality comparative studies are required to confirm the effects of hip arthroscopy on symptoms and structural change in people with hip OA.

Background: standing on textured surfaces or wearing textured shoe insoles can alter balance performance. This evidence, although inconclusive, offers a potential intervention for improving balance in older adults. This study explored the effect of standing on textured surfaces on double-limb balance in older adults and changes in muscle activity as a possible mechanism of effect. Methods: 50 healthy older adults (29 female, age mean [1SD] 75.1 [5.0]) stood quietly in six conditions—eyes open and closed on two different textured surfaces and a smooth surface control. Mediolateral sway, anterior-posterior sway and centre of pressure velocity were extracted from a force platform and lower limb muscle activity collected using surface electromyography (EMG) over 30 s. Results: for mediolateral range with eyes closed, there was a statistically significant effect of texture (F [2, 47] = 3.840, P = 0.033). This was attributed to a 9.2% decrease with Texture 1 compared with Control. No such effects were seen in any other balance variable or lower limb EMG activity for either visual condition. Conclusion: the results suggest an effect of standing on textured surfaces on mediolateral sway in older adults, supporting further work to develop the therapeutic benefits of textured surfaces as an intervention to improve balance.

Background: Evidence suggests that textured insoles can alter gait and standing balance by way of enhanced plantar tactile stimulation. However, to date, this has not been explored in older people at risk of falling. This study investigated the immediate effect of wearing textured insoles on gait and double‐limb standing balance in older fallers.Methods: Thirty older adults >65 years (21 women, mean [SD] age 79.0 [7.1]), with self‐reported history of ≥2 falls in the previous year, conducted tests of level‐ground walking over 10 m (GAITRite system), and double‐limb standing with eyes open and eyes closed over 30 seconds (Kistler force platform) under two conditions: wearing textured insoles (intervention) and smooth (control) insoles in their usual footwear.Results: Wearing textured insoles caused significantly lower gait velocity (P = 0.02), step length (P = 0.04) and stride length (P = 0.03) compared with wearing smooth insoles. No significant differences were found in any of the balance parameters (P > 0.05).Conclusions: A textured insole worn by older adults with a history of falls significantly lowers gait velocity, step length and stride length, suggesting that this population may not have an immediate benefit from this type of intervention. The effects of prolonged wear remain to be investigated.

Objective: Impaired balance control has been reported in the elderly with hip osteoarthritis, yet this relationship has not been explored in young adults with hip chondropathy. This study aimed to determine whether people with hip chondropathy demonstrated impaired balance ability during a dynamic single‐leg squat with eyes open (SquatEO) and a single‐leg standing task with eyes closed (StandEC) and whether hip range of motion (ROM) and hip muscle strength were correlated with balance measures in adults with hip chondropathy.Methods: Sixty‐three adults with hip chondropathy and 60 controls performed 2 tasks: SquatEO and StandEC while standing on a Nintendo Wii Balance Board. Center of pressure (COP) movement in mediolateral and anteroposterior directions was extracted. Hip ROM and muscle strength were measured with an inclinometer and dynamometer. Data were analyzed using an analysis of covariance and stepwise multiple regression model.Results: During SquatEO, greater COP mediolateral range (P = 0.023) and anteroposterior SD (P = 0.043) were observed in those with hip chondropathy compared to controls. No significant between‐group differences were observed for StandEC. Hip external rotation ROM was significantly associated with mediolateral range during SquatEO.Conclusion: Dynamic single‐leg balance squat performance is reduced in people with hip chondropathy compared to healthy adults, but static single‐leg standing balance is not. This may be reflective of reduced control of dynamic movements. Those with greater hip joint external rotation ROM appear to have worse single‐leg squat balance performance. Further investigation into balance deficits associated with hip disease is necessary to establish early identification strategies and a tailored approach to rehabilitation.
