» Approximately 1 in 3 high-impact athletes develops patellar tendinopathy (PT), with the proximal insertion of the patellar tendon being the most commonly affected anatomical site.» Nonoperative treatment options are effective in reducing pain and restoring functionality in most patients with PT. However, operative intervention should be considered when conservative management fails.» A comprehensive review of the literature on surgical procedures, including both open and arthroscopic approaches, was conducted with a specific focus on clinical outcomes and return to sports.» Both open surgery and arthroscopic surgery for PT have demonstrated favorable success rates and return-to-sport outcomes, with arthroscopic treatment potentially expediting the recovery process.

“…Unfortunately, there is still no consensus on the best surgical treatment for chronic patellar tendinopathy. According to the published studies both surgeries give satisfactory results with success rate of more than 77% but arthroscopic surgery gives fewer complications, faster return to preinjury level of sport activities and a non-significant higher success rate [12,14,[23][24][25][26]. Multiple tenotomies and excision of a portion of the tendon can theoretically decrease mechanical properties of the tendon prolonging the patient's return to full function and sports, especially when dealing with athletes, who expect to gain an excellent result to compete at a high level and to practice daily with infrequent rest increasing the risk of failure.…”

Background: The surgical treatment of chronic patellar tendinopathy could be open or arthroscopic. A general agreement on the best surgical treatment option is still lacking.Purpose: The aim of our study was to evaluate the clinical results after a minimally invasive arthroscopic treatment of chronic patellar tendinopathy including a resection of the lower patellar pole.Methods: The study included 14 patients with a mean age of 26 years and chronic patellar tendinopathy refractory to non-operative treatment of more than 6 months. All patients underwent arthroscopic debridement of the adipose tissue of the Hoffa’s body posterior to the patellar tendon, debridement of abnormal patellar tendon and resection of the lower patellar pole. Preoperative and postoperative evaluation was undertaken using clinical examination, magnetic resonance imaging (MRI) and the Lysholm and Victorian Institute of Sport Assessment-Patella (VISA-P) scores. Return to sports and postoperative complications were also assessed. The mean follow-up was 12.2 ± 0.9 months.Results: All 14 patients continued with sport activities, but only 12 of them (85.7%) achieved their presymptom sporting level. The median time to return to preinjury level of activity was 3.9 ± 0.8 months. Patients showed a major improvement in the mean Lysholm score from 51.1 ± 3.8 to 93.4 ± 4.2 (p=0.001) and in the mean VISA-P score from 42.1 ± 3.5 to 86.7 ± 8.4 (p=0.001) There were no postoperative complications.Conclusion: We found that this arthroscopic technique gives reduced morbidity and satisfactory outcome resulting in significantly faster recovery and return to sports in patients with chronic patellar tendinopathy.

“…Clinically, insertional tendinopathies such as QT and PT rupture and jumper’s knee are difficult to repair and treat. 6,17 The QT and PT, including part of the patella, are used as grafts in ACL reconstructions 4,8 and are difficult to regenerate. 5,15 Our results suggest consideration of appropriate treatment strategies based on age and the development of new treatment methods for regeneration of the tendon-bone interface and insertions.…”

Background: Differences in the development of fibrocartilage layers in quadriceps tendon (QT) and patellar tendon (PT) insertion sites are unclear. Because the mechanical environments for the QT and PT are different, the development of the QT and PT insertions may differ. Purpose: To investigate differences in the development of fibrocartilage layers in the QT and PT insertion sites in rabbits through use of quantitative morphometric evaluations. Study Design: Descriptive laboratory study. Methods: This study included 54 male Japanese White rabbits. Animals were euthanized at ages 1 day and 1, 2, 3, 4, 6, 8, 12, and 24 weeks (n = 6 for each age). Chondrocyte number, proliferation, apoptosis, sex-determining region Y box 9 (Sox9)–positive rates, safranin O–stained glycosaminoglycan (GAG) areas, tidemark length, insertion width, and patellar length were evaluated and compared with the same parameters at age 24 weeks and between QT and PT insertion sites. Results: Chondrocyte proliferation was low up to age 2 weeks for QT insertion and low up to 1 week for PT insertion. Chondrocyte apoptosis was high at 1 day and Sox9 expression was low up to 1 week for PT insertion. Sox9 expression was higher in QT than in PT insertion at age 12 weeks. The high chondrocyte count continued to age 1 day in PT insertion and up to 6 weeks in QT insertion. The chondrocyte number was higher in QT than in PT insertion at age 2 weeks. The period of thicker GAG lasted from 2 to 8 weeks in PT insertion and from 1 to 12 weeks in QT insertion. GAG thickness in QT insertion was higher than in PT insertion at age 4 and 12 weeks. Conclusion: Development of fibrocartilage layers in QT and PT insertion sites was completed at age 24 weeks in rabbits. However, the period of high chondrocyte count and period of thicker GAG were longer in QT than in PT insertion up to 12 weeks. Clinical Relevance: Development of fibrocartilage layers in QT and PT insertions differed in rabbits. Our results may contribute to the development of appropriate treatments based on age and the development of methods for regeneration of the insertion.
