Detailed Description
Knee osteoarthritis (OA) is a chronic joint disease and one of the leading causes of disability among adults, resulting in irreversible damage to articular cartilage and subchondral bone, osteophyte formation, joint pain and stiffness. Knee osteoarthritis often makes it difficult to participate in activities of daily living, which can make work difficult or even impossible, especially when it comes to physical activities that impose a great mechanical strain on the knee. For example, when climbing stairs, the pressure on the knees is six times greater than body weight, which is a known risk factor for knee OA due to occupational activities.Given the increasing prevalence of knee OA with the ageing population and the increasing state retirement age in most European countries, the implications of knee OA need to receive special attention.The most common surgical solution is the placement of a total knee arthroplasty, There are several reasons why your doctor might recommend knee replacement surgery. Recommendations for surgery are based on the patient's pain and disability, not age. Most patients who undergo a total knee replacement are between the ages of 55 and 80, but orthopedic surgeons evaluate patients individually. Usually, the surgical procedure takes between 1 and 2 hours. The orthopedic surgeon will remove the damaged cartilage and bone, and then place the new metal and/or plastic implants to restore knee alignment and function.The purpose of the study is to evaluate the acute responses of lower limb strengthening on physical function and pain, in patients operated on by total knee arthroplasty. Candidates for this study will be men and women over 55 years of age who have undergone total knee arthroplasty, who are admitted to the University Clinical Hospital of Valencia, with an intervention date in 2022-2023, and who begin their physiotherapy treatment between days 1-2 post-surgical. Patients will voluntarily participate in the study. All of them will be informed about the objectives and content of the research and written informed consent will be obtained. The study will conform to the Declaration of Helsinki and will be approved by the local ethics committee.Participants will be excluded if they have any involvement in the contralateral lower limb, if they have already had/have any other knee injury or other anatomical part of the intervened MI (in the last year), and if they have any other condition or disease in which there is a contraindication to physical exercise. Also if they participate in other research studies. In addition, if severe neural or vascular injury is evident.In a previous study, initial WOMAC scores had a standard deviation of 11. If the difference between the means of the intervention and control groups is at least 10, a sample size of 20 patients in each group is adequate to reject the null hypothesis with a power of 80% and a significance level of p < 0.05.If possible, two days before the surgical intervention, a video will be sent to the participants with the performance of the exercises to be performed, so that they can check the technique to be executed. Likewise, they will be sent the following information about guidelines to follow for the realization of the tests:
• Try to rest at least 8 hours the post-surgical night. Patients will be treated while admitted to the hospital (between 3 and 4 days), through 1 session / day of approximately 40 minutes.
Evaluation 1 will be performed on the first day after surgery (1st postoperative day) and evaluation 2 on the day of hospital discharge (3rd postoperative day).EXERCISE PROGRAM WITH ELASTIC RESISTANCE:
- All exercises are done until the maximum number of repetitions is reached, since they will only be done once / day.
- During the first day, each exercise should begin with 2 sets of 2 repetitions as a warm-up and calculation of the appropriate intensity. The appropriate intensity will be the one where the patient tells us that he perceives 5-6 out of 10 on the Borg CR10 scale after finishing 2 repetitions.CONTROL GROUP EXERCISE PROGRAM:
The patients of the control group will perform the physiotherapy exercises following the RHB protocol in ATR of the University Clinical Hospital of Valencia.

Kinesiophobia
Time Frame: 3 days
|
Kinesiophobia will be evaluated (REPASAR) mainly through the Spanish version of the Kinesiophobia Tampa Scale in a selfrecorded manner.

|
Pain intensity
Time Frame: 3 days
|
The patient will be mark a point on the scale and subsequently, the clinician or researcher quantifies the number of mm indicated by the patient.
The level is from 0 to 100 mm.
|

|
Pain percepcion
Time Frame: 3 days
|
The chronic pain perception will be measured by Questionnaire on Perception of Self-Efficacy in the Face of Chronic Pain (CPSS) that contains 19 items and evaluates 3 domains: self-efficacy for pain management (α=0.72),
physical functioning (α=0.98) and symptom management (α=0.85).

Range of motion
Time Frame: 3 days

The degrees of movement (ROM) of the following joints shall be actively and passively measured by means of a manual goniometer.

Isometric knee extension/flexion force
Time Frame: 3 days

They will be evaluated with a portable handheld dynamometer.maximum
contractions of 5 seconds will be performed, separated by 1 minute of rest, selecting the average value of these 3 for later analysis.

Self-administered physical function
Time Frame: 3 days
|
WOMAC questionnaire be used to assess stiffness, pain and physical function in a self-administered manner.
The questionnaire is a multidimensional scale composed of 24 items divided into 3 domains: functional pain (5 items), stiffness (2 items) and difficulties in activities of daily living (17 items).

Catastrophism
Time Frame: 3 days
|
Scale of Catastrophism before pain in a self-registered way, which consists of 13 items that describe different thoughts and feelings associated with pain.
The scale has 5 degrees, being 0 nothing at all, 1 a little, 2 moderately, 3 a lot and 4 all the time.
The subject must mark his situation in each case.
The scale consists of 13 items in total (0-52 points).
Higher scores will indicate higher levels of pain catastrophism.

The Time up and go (TUG) measures the time it takes for a person to get up from a standard chair (without using their arms to get up), walk to a line on the floor 3m away, turn around, walk back to the chair, and sit down again.
Walking aids (e.g.
walker) are allowed if necessary.
Two tests are performed, with one minute of rest between them, using the highest value for analysis.

It was assessed by measuring knee circumference.
Patients lie on a stretcher with the operated knee relaxed and extended as much as possible.
If the knee can extend below 0°, a cylinder is placed under the heel.
A non-elastic tape measure was carefully placed and adjusted 1 cm above the base of the kneecap.
Knee joint circumference was measured twice and the highest value was used for analysis.

UDP is defined as the minimum amount of pressure in which a feeling of pressure is transformed into a sensation of pain.
The mechanical pressure instrument, called an algometer (Wagner Instruments, Greenwich, CT, USA), will be used in this study.
This consists of a round rubber disc (1 cm2 in surface) attached to a pressure (force)

we assessed the number of days on which participants were taking painkillers during the week.
The following question was asked of the participants: "As a result of the pain, how many days during this week did you take painkillers?"
Participants had to respond with a number of 0-7, and the drugs administered were recorded in the hospitalization room.
