Patellar tendon ossification after partial patellectomy: a case report

Journal of Medical …, 2010

Introduction: Patellar tendon ossification is a rare pathology that may be seen as a complication after sleeve fractures of the tibial tuberosity, total patellectomy during arthroplasty, intramedullary nailing of tibial fractures, anterior cruciate ligament reconstruction with patellar tendon autograft and knee injury without fracture. However, its occurrence after partial patellectomy surgery has never been reported in the literature. Case presentation: We present the case of a 35-year-old Turkish man with a comminuted inferior patellar pole fracture that was treated with partial patellectomy. During the follow-up period, his patellar tendon healed with ossification and then ruptured from the inferior attachment to the tibial tubercle. The ossification was excised and the tendon was subsequently repaired. Conclusion: To the best of our knowledge, this is the first report of patellar tendon ossification occurring after partial patellectomy. Orthopaedic surgeons are thus cautioned to be conscious of this rare complication after partial patellectomy.

Anatomical study of the inferior patellar pole and patellar tendon

Scandinavian Journal of Medicine & Science in Sports, 2017

In this study, detailed investigations of the shape of the inferior patellar pole, the site of the patellar tendon attachment, and the length and course of the patellar tendon were performed with the aim of examining the anatomical factors involved in the developmental mechanism of patellar tendinitis. The investigation examined 100 legs from 50 cadavers. The inferior patellar pole was classified into three types: Pointed, Intermediate, and Blunt.

The length of the patellar tendon was measured from the tibial tuberosity to the inferior patellar pole. The Pointed Type was seen in 57% of legs, the Intermediate Type in 21%, and the Blunt Type in 22%. Twenty-one legs were the Pointed Type, as well as the Anterior Type. The patellar tendon was significantly shorter with the Posterior Type than with the Anterior Type. The Blunt Type also had a significantly shorter patellar tendon than the Pointed Type. In legs that were both the Pointed Type and the Anterior Type, the inferior patellar pole and the proximal posterior surface of the patellar tendon impinged during knee flexion due to the posterior tilt of the patella, suggesting the possibility that this may induce damage. With the Posterior Type and Blunt Type, on the other hand, the possibility of strong tensile stress on the tendon fibres of the posterior facet of the inferior patellar pole was suggested.

Patellar Tendon Ossification or Reformation of Patella after Partial Patellectomy? A Case Report

Global journal of surgery, 2014

We present a curious case of spontaneous reformation of patella/patellar tendon ossification after partial patellectomy. This is a very rare pathology that has been reported as a complication after sleeve fractures of the tibial tuberosity, total patellectomy during total knee arthroplasty, intramedullary nailing of tibial fractures, anterior cruciate ligament reconstruction with patellar tendon autograft and knee injury without fracture. Patellar tendon ossification after partial patellectomy has been reported just once in literature. We present the second one of this nature. The patellar tendon ossification resembled a reformation of the patella and could easily be mistaken for an inadequate removal of the patellar remnant.

Massive Patellar Tendon Ossification: Excision and Simultaneous Total Knee Replacement

Tendon ossification has a multifactorial aetiology. We present a case of a massive ossification within the substance of patellar tendon. A 79-years-old male who had a previous history of patellar tendon rupture and its surgical repair. He gradually developed a large bony mass within the patellar tendon and progressive symptoms of arthritis in the knee joint. The patient underwent a total knee replacement along with simultaneous excision of the entire bony lump and primary repair of the patellar tendon. The knee was mobilised gradually after surgery and achieved satisfactory range of motion, function and alleviation of symptoms without any complication.

Surgical treatment of patellar tendinitis

Knee Surgery Sports Traumatology Arthroscopy Official Journal of the Esska, 1993

Patellar tendinitis is an overuse syndrome affecting the origin of the patellar tendon and its underlying part. Ultrasonography is useful to investigate tendinous pathology. It describes the anatomical lesions and their extent. Surgical excision of irreversible lesions, demonstrated on ultrasonography, is a logical attitude which provides good results.

Arthroscopic Resection of the Lower Patellar Pole in Patients With Chronic Patellar Tendinosis

Arthroscopy: The Journal of Arthroscopic & Related Surgery, 2008

The aim of this prospective study is to evaluate the clinical results of arthroscopic resection of the lower patellar pole in patients with patellar tendinosis. Methods: Twenty patients underwent an arthroscopic resection of the lower patellar pole between 2002 and 2004. All of them were evaluated at 6 weeks and 3, 6, 12, and 24 months after surgery using the Tegner activity level, the Lysholm score, the Kujala score, a modified jumper's knee classification according to Blazina, and visual analog scales for pain, function, and satisfaction. Clinical evaluation was performed 2 years after surgery. In addition, magnetic resonance imaging was performed preoperatively and at a 2-year follow-up. Results: By 6 weeks postoperatively and at every other follow-up visit, significant improvements were seen in the Lysholm score (P ϭ .001), the Kujala score (P ϭ .001) and the visual analog scales. The Tegner score improved significantly by 3 months postsurgery (P ϭ .01). Two years after surgery, the Tegner score improved from 4.4 Ϯ 2.9 to 7.95 Ϯ 1.6 (P Ͻ .0001); the Lysholm score from 57.1 Ϯ 17.1 to 97.3 Ϯ 4.4 (P Ͻ .0001); and Kujala score from 53.7 Ϯ 14.7 to 95.4 Ϯ 7.8 (P Ͻ .0001). The jumper's knee classification showed excellent (stage 0) or good (stage I) results in 18 of 20 patients. At follow-up, all but one magnetic resonance image showed hypodens areals in the proximal aspect of the patellar tendon, and small osteophytes were seen in some cases at the resection area. These findings did not seem to have any influence on the results. Conclusions: The arthroscopic resection of the lower patellar pole as a minimal invasive method to treat jumper's knee provides satisfactory clinical results in knee function and pain reduction with fast recovery and return to sport activities. Level of Evidence: Level IV, therapeutic case series. FIGURE 4. The mean values of the Lysholm score (white) and the Kujala score (black) are shown. Significant improvement is achieved at 6 weeks after surgery.
