Trial Title: Effectiveness of Two Exercise Protocols in the Treatment of Patients With Patellar Tendinopathy

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: SINGLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* patients with chronic unilateral patellar tendinopathy confirmed by the reproduction of the pain during the palpation test in the region of the lower pole of the patella~* presence of pain for three months or more~* both genders~* body mass index less than 30 kg/m²~* age between 18 and 40 years~* practice of physical activity on a regular basis~* pain intensity ≥ 3 points on the pain numerical rating scale in the anterior region of the knee, specifically in the region of the lower pole of the patella when performing squatting, jumping or activities with change of direction~* score \< 80 points on the Victorian Institute of Sport Assessment-Patella (VISA-P)~* blazine functional scale between 1 and 3~Exclusion Criteria:~* patients who have previous pain in the knee that does not correspond to patellar tendinopathy~* previous rupture of the patellar tendon (blazin functional scale at level 4)~* previous surgery or infiltration of the patellar tendon in the last six months~* inflammatory diseases~* diabetes mellitus~* lower limbs injuries~* other chronic pain conditions that prevent exercise, such as severe hip and knee osteoarthrosis and joint fractures.

Study Arms:
- Eccentric (Type: ACTIVE_COMPARATOR): Patients allocated in this group will perform three sets of 15 unipodal squats with the affected limb on an inclined plane. The patient will be instructed to perform only the eccentric phase of the exercise, keeping the torso erect and flexing the knee up to 90 degrees. The return to the initial position will be performed with the unaffected leg. To increase exercise load, the patient will carry a bag with washers. This protocol will last eight weeks, with 24 face-to-face sessions.~Both groups will also receive a protocol with complementary isotonic exercises, focusing on the strengthening of gluteus maximus, gluteus medius, hamstrings and calves.
- Modified protocol (Type: EXPERIMENTAL): Patients allocated in this group will receive treatment based on a protocol published in a clinical practice guide, with modifications to make the protocol more pragmatic. Thus, the use of mechanotherapy devices will be replaced by free weight exercises, so that the protocol can be performed in environments that do not offer this type of machinery. This protocol is composed of four exercise stages, being the first three stages performed in the presence of the physiotherapist, and will last eight weeks with approximately 24 face-to-face sessions.~Both groups will receive a protocol with complementary isotonic exercises, focusing on the strengthening of gluteus maximus, gluteus medius, hamstrings and calves.

Based on this trial design, predict the completion outcome and termination type (if applicable).
