Abstract [en]

PURPOSE: Treatment of patellar tendinopathy/jumper's knee with ultrasound-guided sclerosing injections or ultrasound-guided arthroscopic shaving has shown good clinical short-term results. Former studies indicate that the tendon thickness and structure stays unaffected after successful treatment. The aim of this study was to evaluate the sonographic findings and clinical outcome 3-5 years after treatment of patellar tendinopathy with ultrasound-guided sclerosing injections or arthroscopic shaving.

METHODS: Fifty-seven patellar tendons (43 patients) with chronic patellar tendinopathy were evaluated, with ultrasound, colour Doppler (CD) and visual analogue scale (VAS) for pain and satisfaction with treatment, 3-5 years after treatment. Functional status was evaluated with a single question-"Back in full loading activity?" yes or no.

RESULTS: At endpoint (mean 46 months), there was a significant decrease in anteroposterior thickness of the proximal patellar tendon in patients treated with ultrasound-guided arthroscopic shaving but not after sclerosing injections. Tendon structure had improved, and CD local blood flow had diminished significantly in both groups. There were good clinical results with a significant decrease in VAS for pain after sclerosing injections (VAS 64 ± 18 → 17 ± 23) with 74 % satisfied patients and also after arthroscopic shaving (VAS 77 ± 16 → 13 ± 23) with 80 % satisfied patients. There were no significant differences in VAS between groups. A significant correlation between low local blood flow and high patient satisfaction was found.

CONCLUSIONS: Tendon thickness decreased over time after ultrasound-guided arthroscopic shaving, and tendon structure and local blood flow decreased after both treatments. There were good, and similar, clinical results with both methods. LEVEL OF EVIDENCE: III.
