Description of intervention(s) / exposure
At first, a meeting will be held with the patients under study where they will be informed and any doubts that may arise in relation to the investigation will be resolved. In addition, the correct adaptation of these to the inclusion and exclusion criteria of our study will be verified. Subsequently, they will be given individually the informed consent prepared expressly for the present study, the doubts arising with respect to this one will be resolved and their signature will proceed. At this time, and individually again, we will proceed to the development of the Clinical History of Physiotherapy where only the information necessary for our study will be collected.
To emphasize in this point that the participants will grant their consent for the treatment of the data obtained for scientific purposes, according to the legal norms.

Next, the patients will be randomly assigned to two groups: control group and experimental group. The randomization of the sample was done through the EPIDAR software in version 3.1 between the Experimental Group and the Control Group
Subsequently, the evaluations and measurements of the study variables will be carried out by the research team.
CONTROL GROUP: You will be provided exclusively therapeutic exercises protocol to develop in the home setting that you must perform following a daily activity for three weeks.

EXPERIMENTAL GROUP: After the initial evaluation, the first 10 treatment sessions will be developed at the rate of five daily sessions in the first week, three sessions on alternate days in the second week and two sessions on alternate days in the third week (3 weeks in total), applying the monopolar capacitive diathermy with radiofrequency in the anterior aspect of the knee, in dynamic application in one of the members: affect or randomized (uni or bilateral pathology, respectively). This diathermy will be combined with a therapeutic exercise program supervised by a Physiotherapist.
The treatment is administered with a pulsatile short-wave equipment and inductive electrodes of 100 W peak power, with a frequency of application of twice daily with a dose submitis (grade I), for 10 min, with a frequency of repetition of the impulses of 46 Hz and a pulse duration of 0.2 ms
After the tenth treatment session all the measurements will be repeated following the same environmental conditions as at the beginning and by the evaluators themselves to the components of both groups.

Rehabilitation
Comparator / control treatment
CONTROL GROUP: The patients will be exclusively provided with a protocol of therapeutic exercises to develop at home that must be performed daily for a minium period of three weeks.

The protocol of therapeutic exercises will include a combination between hip and knee-targeted exercises in order to reduce pain and improve the patients' functional outcomes. The hip-targeted exercises will include posterolateral hip musculature. The knee-targetted exercises will include both types of exercises: those that implies body weight bearing and those which not. In the beginning of the protocol we will prefer to introduce hip-targeted exercises withoutaddition of external weight.
An example of non weight bearing exercise would be resisted extensión, paying special atention to the internal component of the quadriceps and an example of weight bearing exercise would be adapted squats.

Outcomes
Primary outcome [1] 320201 0
The perception of pain through the Visual Analogue Scale (EVA). This variable has been obtained through a validated scale of 10 centimeters (0-10), where the subject self-positioned from absence of pain to the worst bearable pain
Timepoint [1] 320201 0
Two evaluations were performed by physiotherapists: before the intervention and when the intervention was finished (after 10 sesions).
Our objective is to study the effects on the short term.
Primary outcome [2] 320203 0
The functional disability, quantified by means of the tests: Kujala Score.

In addition an anthropometric study of knee joint range of movement will be performed. Evaluating the Active and Pasive Knee's Range of Movement using universal goniometer measurement. we pay special attention to the possible restrictions in the normal range of motion.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients diagnosed with unilateral or bilateral PFPS will be divided into two groups, randomly selected (experimental group and control group), of 30 subjects each.

Allocation was concealed and it was done by central randomisation by computer (EPIDARcomputer program).

The subjects of the experimental group will undergo a program of supervised physical therapeutic exercise. And the subjects of the control group will follow the medical-pharmacological treatment and the ergonomic recommendations according to the established protocol.

The target population will be all patients diagnosed with patellofemoral pain syndrome (PFPS) unilaterally or bilaterally, from the health area of La Rinconada while the eligible population will be composed of all those patients residing in or around Seville who can and wish to be part of it. of the study and that they meet the inclusion and exclusion criteria..
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (EPIDAR versión 3.1)
Masking / blinding
