Summary

Ultrasonography aids in diagnosing and monitoring jumper's knee (patellar tendinitis). This imaging technique revealed tendon anomalies in all affected athletes, guiding effective treatment strategies for athletes with knee pain.

Background:

Jumper's knee, or patellar tendinitis, affects athletically active individuals.
Accurate diagnosis and monitoring are crucial for effective treatment of patellar tendinitis.

Purpose of the Study:

To evaluate the utility of ultrasonographic examination in diagnosing and managing jumper's knee.
To correlate ultrasonographic findings with clinical presentation and treatment outcomes in athletes.

Main Methods:

Ultrasonographic examination of 25 athletically active patients (15-45 years) with jumper's knee.
Comparison with a control group of 15 healthy, athletically active subjects (25-35 years).
Assessment of tendon anomalies including thickening, heterogeneous structure, and envelope irregularities.

Main Results:

All 32 affected tendons showed ultrasonographic anomalies.
Acute cases presented with tendon thickening/swelling; heterogeneous structure and envelope irregularities were also common.
Conservative treatments (physical therapy, electrotherapy, massage) were effective for acute cases and some chronic cases.

Conclusions:

Ultrasonography provides precise information for diagnosing and monitoring jumper's knee.
A combination of conservative and surgical treatments can lead to successful recovery in athletes with patellar tendinitis.
All patients in the study reported being healed at least 2 years post-treatment.
