“…Although open techniques yield equivalent VISA-P scores compared to arthroscopy, due to the very short length of follow-up, side effects, complications, delayed failure may be underrepresented. Compared to open surgical techniques APR has minimal risk for complications and demonstrates reduced postoperative pain and knee stiffness (never observed in our practice) [ 40 ]. Outcome of our study is comparable to previous studies on arthroscopic techniques with the major difference, that we have solely performed a patellar release without any tendon debridement and/or or osseous resection [ 39 ].…”

BackgroundArthroscopic patellar release (APR) is utilized for minimally invasive surgical treatment of patellar tendinopathy. Evidence regarding long-term success following the procedure is limited. Also, the influence of age and preoperative performance level, are incompletely understood. The aim of this study was to investigate whether APR translates into sustained pain relief over a long-term follow-up in athletes undergoing APR. Furthermore, we analyzed if age influences clinical and functional outcome measures in APR.MethodsBetween 1998 and 2010, 30 competitive and recreational athletes were treated with APR due to chronic refractory patellar tendinopathy. All data were analyzed retrospectively. Demographic data, such as age or level of performance prior to injury were extracted. Clinical as well as functional outcome measures (Swedish Victorian Institute of sport assessment for patella (VISA-P), the modified Blazina score, pain level following exercise, return to sports, and subjective knee function were assessed pre- and postoperatively.ResultsIn total, 30 athletes were included in this study. At follow-up (8.8 ± 2.82 years), clinical and functional outcome measures such as the mean Blazina score, VISA-P, VAS, and subjective knee function revealed significant improvement compared to before surgery (P < 0.001). The mean time required for return to sports was 4.03 ± 3.18 months. After stratification by age, patients younger than 30 years of age yielded superior outcome in the mean Blazina score and pain level when compared to patients ≥30 years (P = 0.0448). At 8 years of follow-up, patients yielded equivalent clinical and functional outcome scores compared to our previous investigation after four years following APR.ConclusionIn summary, APR can be regarded a successful, minimally invasive, and sustained surgical technique for the treatment of patella tendinopathy in athletes. Younger age at surgery may be associated with improved clinical and functional outcome following APR.Electronic supplementary materialThe online version of this article (10.1186/s12891-017-1851-3) contains supplementary material, which is available to authorized users.

Chronic patellar tendinosis (jumper's knee) is a common problem among athletes. Conservative treatment is successful in most of the cases including, among others, the use of nonsteroidal anti-inflammatory drugs, local cryotherapy, eccentric muscle training, limitation of sports activity, and local infiltration. In approximately 10% of conservatively treated patients, conservative treatment fails and surgery is required. Different open and arthroscopic surgical techniques have been described in the literature. The presented all-arthroscopic surgical technique for the treatment of chronic patellar tendinosis includes debridement of soft tissue at the lower patellar pole and resection of the bony lower patellar pole. It leads to excellent clinical results comparable to described open treatment and provides the benefits of a minimally invasive and safe procedure with a faster recovery and return to sporting activities after surgery. An additional bony resection in case of a prominent lower patellar pole does not lead to a significant extension of the operation time and may avoid a relapse or treatment failure in selective cases. Therefore, arthroscopic treatment such as the presented technique may be the preferred method for surgical treatment of chronic patellar tendinosis.

We present an overview of imaging and intervention of the extensor mechanism of the knee. Particular focus is placed on the evaluation of patellofemoral tracking disorders, patellar and quadriceps tendinosis and tears, patellar fracture, lateral patellar condyle patellar friction syndrome, and prepatellar bursitis. Anatomical and biomechanical factors contributing to these disorders are considered. Imaging evaluation is presented in a clinical context, and therapeutic options for these disorders are discussed. Image-guided therapy options for symptomatic patellar tendinosis are also described and illustrated.
