The Jumper's Knee - a New Look at Non-surgical Treatment. Pilot Study

There are many opinions and views regarding the methods of treatment of patellar ligament enthesopathy. No gold standard of treatment exists. This paper presents our approach involving conservative treatment and an appropriate rehabilitation regime. Our aim was to assess the effectiveness of a combination of various conservative treatment techniques and the time needed to return to sport.

The study enrolled 14 patients treated in 2019 and 2020. Knee joint evaluation was based on clinical and radiological examination (sonography and MR). All patients were treated conservatively according to a specially prepared treatment protocol. Patients were evaluated at two-week intervals until the symptoms subsided completely. The KOOS, Kujala and SF36 questionnaires were used to evaluate the results.

All of the patients returned to painless physical activity within 3-4 weeks from the start of treatment. In the group of professional athletes, 100% returned to sport. The return to sport took slightly longer for pa-tients with bilateral (5-6 weeks) in comparison to unilateral jumper's knee (3-4 weeks). The longest period of return to sport, in a patient who had severe pain at rest before starting treatment, was 7 weeks. Statistically significant improvement was noted in all of the questionnaires used and in all subdomains at 6 months after the beginning of the treatment.

1. The conservative approach proposed by us generated promising results in the treatment of the jumper's knee. 2. A 100% rate of return to sport was recorded among our patients.
