Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Thus, this study investigates the feasibility and acceptability of foot insoles as a gait modification tool among Saudi Arabian knee osteoarthritis patients and physiotherapists.
This study aims to answer the following:
* Which gait modification intervention is most likely to be implemented in Saudi Arabia (SA) clinical practice, taking context, patients' clinical and research evidence into consideration?
* In Saudi Arabia, can this proposed foot-insole intervention be implemented? Is there sufficient experience among physiotherapists regarding gait modification to deliver it, and will patients engage with it? How can KOA rehabilitation outcomes be evaluated in the future?
The participants will be conducted over three phases:
1. The patients' interview and therapists' focus group discussion will be used to examine KOA patients' and clinicians' perspectives on enabling and accepting gait modifications in phase 1.
2. The feasibility study will explore how a small number of KOA patients tolerate gait modifications and consider the most relevant outcome measures, such as pain and function, in phase (2).
3. A small group of knee osteoarthritis patients and their physiotherapists who participated in phase (2) will be asked to participate in a descriptive survey in phase (3). To examine the acceptability and feasibility of the study intervention in phase (2).

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A notable number of Saudi Arabians suffer from knee osteoarthritis (KOA), which reported a 29.5% prevalence of KOA; another recent study reported a 24.5% prevalence of KOA among the elderly. A 2002 study found that 30.8% of those aged 46-55 and 60.6% aged 66-75 were affected. Thus, KOA is roughly equally distributed between genders and is more prevalent among elderly and overweight individuals, so policymakers should focus on raising awareness to prevent and treat affected individuals. The healthcare system in SA is publicly funded and accessible; 79% of patients use the public system, and the rest obtain private care. In most cases, private patients have insurance coverage. The public healthcare system has three primary, secondary, and tertiary care levels. Rehabilitation and gait modification investigations are not available at the primary level.
This snapshot of the literary review raises questions about the viability of the long-term use of learned/assistive gait modifications. The studies reported dissatisfaction with the gait modification approach but gave no reasons. Since most studies focus on results in a short time or a specific area, pre-training courses measuring acceptability and commitment can fill the gaps in previous studies. After determining the importance of gait modification, the question becomes, should it be integrated into the therapy strategy or other rehabilitative methods to increase the treatment's clinical efficacy? It is essential to understand the practices, views and expectations of KOA patients and health professionals concerning gait modifications.

NA
SINGLE_GROUP
* During the session, the researcher will observe participants inside the clinic and ensure that the modified gait application is applied, and outside the clinic will be followed by telephone.
* Participants will walk on the gym floor or an adjusted treadmill for at least 15 to 20 minutes during each session. Participants will be instructed to use the mirror for feedback and achieve the target modified gait procedure. However, it will be emphasised gait modification procedures exhibited at baseline pain and function, and then at the end of the trial, it will focus on subjects' acceptability.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Feasibility intervention
The intervention will be foot insole (lateral wedge) insole, which has already been delivered in routine UK NHS and SA environments by at least one physiotherapist. Clinical testing will be done with 15-25 knee osteoarthritis subjects. These individuals will be assigned to a single intervention group for 4-6 weeks of re-gait training intervention. It involves a personalised gait retraining programme (sizable insole) for the KOA subjects to evaluate the impact on knee pain and improve function. It is set within 4-6 weeks of VAS and the WOMAC tools for knee pain \& function outcome.
Lateral Wedge insole
Insoles with lateral wedges are placed in patients' shoes to control biomechanical knee loading on the medial side of the knee. Insoles with lateral wedges are designed to be thinner on the inside (medially of the foot) and thicker on the outside (laterally of the foot) to relieve knee biomechanical loading parameters.
