This study is a feasibility study. It will assess areas of uncertainty relating to the implementation of an individualised exercise programme for patients with a recent kneecap dislocation. This will help determine if a future larger study is feasible, and inform the design and conduct of future research that would aim to optimise outcomes after a kneecap dislocation.
The investigators aim to recruit 15 adult participants with a recent, first-time or recurrent kneecap dislocation, from an acute hospital. Participants will receive up to 6 physiotherapy sessions over 3 months. The investigator's exercise programme aims to improve leg muscle strength and facilitate a return to the participant's usual activities. This may include activities such as hopping and changing direction which differentiates it from other programmes. Participants will be required to perform the exercise programme 3 times a week independently. Strategies to increase adherence to the exercise programme will also be used. This study is part of a Masters in Clinical Research funded by the National Institute for Health Research

The intervention will be comprised of up to 6, one-to-one physiotherapy sessions, over a maximum duration of 3 months. 1 or 2 extra sessions are allowed if deemed essential by the participant's physiotherapist. Less than 6 physiotherapy sessions can be agreed with the participant if they have achieved their goals. Throughout this time participants will be required to perform an exercise programme a minimum of 3 times per week. The exercise programme aims to increase leg muscle strength and facilitate a return to the participant's usual activities. It may include hopping and change of direction tasks if these are activities the participant would normally do. Behavioural change techniques to increase participant adherence to the exercise programme will also be used.

Eligibility Rate
Percentage of patients with a diagnosed lateral patellar dislocation, screened for eligibility, who satisfied the eligibility criteria
Time frame: 15 weeks
Recruitment Rate
Percentage of eligible participants who consented to participate in the study
Time frame: 15 weeks
Attrition
Percentage (0-100%) of participants enrolled in the study who failed to provide any 12 week follow-up data
Time frame: 12 weeks
Acceptability [Participant Satisfaction]: Questionnaire
Participant response to an internally designed patient questionnaire. This will measure several domains of of intervention acceptability: satisfaction with treatment, self-efficacy, burden of treatment, and intention to adhere. 6 questions will assess satisfaction with treatment, 3 questions will assess self-efficacy,1 question will assess burden of treatment and 1 question will assess intention to adhere. Each question will use a 5 point likert scale (0-4) with lower scores indicating higher satisfaction, self-efficacy, and intention to adhere. Each question will be reported individually.
Time frame: 12 weeks
Adherence
Percentage (0-100%) of scheduled physiotherapy sessions attended
Time frame: 12 weeks
Adherence [Participant-reported Adherence to Home Exercise Using a Likert Scale]
Participant response at follow-up to the question 'how often did you perform your exercises at least three times a week?' using a five-point Likert scale (0-4) anchored at 'always' (0) and 'never' (4)

Acceptability of Outcome Data Collection
Percentage (0-100%) of questions completed in the following patient-reported outcome measures: Lysholm Knee Scoring Scale, Tegner Activity Scale, EQ-5D-5L, completed at baseline and returned at 3-month follow-up
Time frame: 12 weeks
Number of Treatment Related Adverse Events Experienced by Participants
The total number and type of treatment related adverse events experienced by participants will be recorded. This will be recorded from commencement of the intervention to 12 week follow-up. Treatment related adverse events will be recorded by physiotherapists at each physiotherapy session and by participant self report at 12 week follow up.
Time frame: Through 12 weeks after first physiotherapy session
Presence/Absence of Common Lateral Patella Dislocation Diagnostic Criteria
Following diagnosis of a lateral patellar dislocation by an orthopaedic surgeon or physiotherapist, the clinician will be asked which of the following proposed assessment findings to include in the eligibility criteria for future studies, were present/absent during their clinical examination: positive patella apprehension test, visible knee joint effusion or haemarthrosis, medial patellofemoral ligament tenderness on palpation, and a convincing patient history of a visible deformity on the lateral aspect of the knee or a sensation of the patella 'popping' out of joint followed by spontaneous reduction
Time frame: Baseline
Tegner Activity Scale Questionnaire
This measures activity on a scale from 0-10, with higher scores indicating higher activity. It will be administered as a patient completed questionnaire.
Time frame: 12 weeks
Lyhsolm Knee Scoring Scale Questionnaire
It is scored from 0-100 with lower scores indicating higher pain and disability. It will be administered as a patient completed questionnaire.
Time frame: 12 Weeks
Quality of Life Using the EQ-5D-5L Questionnaire
This assess quality of life using 5 domains: mobility, self-care, usual activities, pain/discomfort and anxiety/depress, each containing 5 options. These domains are combined to give a single score ranging from -0.594 to 1 for UK populations, with higher scores indicating higher quality of life. Participants rate their overall health on a visual analogue scale from 0 (worst health you can imagine) to 100 (the best help you can imagine). It will be administered as a patient completed questionnaire.
Time frame: 12 weeks
