Open Patellar Tendon Debridement for Treatment of Recalcitrant Patellar Tendinopathy: Indications, Technique, and Clinical Outcomes After a 2-Year Minimum Follow-up

BACKGROUND: Patellar tendinopathy can be treated surgically for patients that have failed at least 1 year of nonoperative treatment who continue to have debilitating symptoms. Patellar tendinopathy can cause significant functional deficits, yet little has been reported about the operative treatment of patellar tendinopathy. HYPOTHESIS: A combined arthroscopic and open surgical technique for the treatment of recalcitrant patellar tendinopathy results in an improvement in function and pain at a minimum 2-year follow-up. The purpose of this study was to present the indications, combined surgical technique, rehabilitation protocol, and the 2-year minimum follow-up results of the operative treatment of recalcitrant patellar tendinopathy. STUDY DESIGN: Retrospective case series. METHODS: A retrospective review was performed of all patients who underwent a surgical primary patellar tendon debridement for recalcitrant patellar tendinopathy by a single surgeon between July 1999 and December 2005. Every patient failed at least 1 year of nonoperative treatment. Patients were excluded from the study if they had previous open knee surgery. Validated patient-reported outcome scores were used to assess function and pain levels pre- and postoperatively (Lysholm, International Knee Documentation Committee, Tegner activity, and visual analog pain score). RESULTS: Thirty-four consecutive patients (37 consecutive cases) with mean follow-up 3.8 ± 1.6 years (range, 2-7.6 years) underwent the procedure with no complications. The mean age at surgery was 29 years (range, 14-51 years). Postoperatively, the visual analog score decreased by an mean of 6 points (range, 1 to −10, P < 0.001), and patients were able to return to their preinjury Tegner activity level. When asked if they were satisfied by the overall outcome of their surgery, 28 patients (82%) were completely or mostly satisfied with their surgical outcome on a particular knee; 6 (18%) were somewhat satisfied; and 2 (6%) were dissatisfied. Twenty-seven patients (79%) said they would have the surgery again. CONCLUSION: The combined arthroscopic and open surgical technique described for chronic recalcitrant patellar tendinopathy successfully reduces knee pain and allows return to preinjury level of activity.
