Brief Summary

Patellar tendinopathy (PT) is a commonly used term for the clinical manifestation of patellar tendon pain and functional limitation with multifactorial etiology. It occurs in both athletes and general population in all age groups. It is often characterized as an overuse injury resulting from chronic failure of the healing response that is not strictly linked to inflammatory or degenerative processes.

EXPERIMENTAL

Device: Extracorporeal Shockwave Therapy

Interventions

Extracorporeal Shockwave Therapy DEVICE

The low-energy focused ESWT was applied using the BTL-6000 FSWT device with piezoelectric generator and a coupling pad which modulates penetration depth to 0-35 mm. The setting was chosen based on ISMST guidelines (https://shockwavether apy.org). Energy flux density varied between 0.14 and 0.18 mJ/ mm2 due to patient tolerance, frequency was set at 8 Hz. A total of 2000 shocks were applied semi-statically to the most defined pathological area in the patellar tendon followed by2000 shocks dynamically to the quadriceps muscle.

Eligibility Criteria

• Age: 15 Years - 18 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• Has patellar tendon pain, which limits (at least in part) the quality of normal daily.
• Has clinical manifestation of PT (pain and impaired function) confirmed by a clinician.
• Has symptoms only in one leg, the other one is asymptomatic.
• Normal BMI.

You may not qualify if:

• Any contraindication for ESWT is present (according to the International Society for Medical Shockwave Treatment \[ISMST\] consensus at https://shockwavetherapy.org).
• They were aware of any symptomatic mechanical tendon damage in the past (e.g. partial or complete rupture in relation to the injury), neurological, oncological, or systemic disease (e.g. neuropathy, lupus or rheumatic arthritis) coexists
• They were already treated for PT elsewhere up to 3 months prior to the study (e.g. platelet- rich plasma therapy, physiotherapy incl. resistance training or ESWT).
