Neglected bilateral rupture of the patellar tendon: A case report

Simultaneous bilateral rupture of the patellar tendon (PT) is extremely rare and is generally associated to some chronic diseases. When the rupture becomes chronic, it is more difficult to repair that as it remained untreated.The diagnosis, which is clinical, is often delayed, guided by standard radiography and confirmed by ultrasound or MRI.The management of a bilateral neglected, chronic patellar tendon rupture must address some serious difficulties: the proximally retracted patella, the reconstruction of the patellar tendon, finally, the temporary protection of this repair.We report a case of neglected bilateral rupture of the patellar tendon in a chronic hemodialysis patient, treated with a plastic surgery of the ipsilateral quadriceps tendon.     

Neglected rupture of the patellar tendon

Neglected rupture of the patellar tendon is a rare but well recognised complication of knee trauma. We present the case of a 43-year-old man who sustained a complete rupture of the patellar tendon of his left knee following a fall. Clinical diagnosis was delayed by 2 months and was confirmed by magnetic resonance imaging. Treatment began with skeletal patellar traction and was followed by late reconstruction of the patellar tendon and transfer of the gracilis and semitendonosus tendons supplemented by figure-of-eight tension band wiring.

Spontaneous bilateral patellar tendon rupture: a case report and review of the literature

Bilateral rupture of the patellar tendon is a very rare injury. It occurs in association with chronic systemic diseases or corticosteroid medications. We report a case of a 13-year-old child with Ehlers-Danlos syndrome presenting a bilateral patellar tendon disruption of proximal insertion that occurred with a trivial trauma. Surgical management consisting in tendon repair with a suture anchor technique protected temporarily with a cerclage wiring gives a good outcome.     

Neglected patellar tendon rupture: a case of reconstruction without quadriceps lengthening

Neglected rupture of the patellar tendon is a rare, can be easily missed in a group of patients. We present a 24 year old, male patient who sustained right femoral diaphyseal and tibial plateau fractures and a patellar tendon rupture following a motor vehicle accident. The fractures were treated by open reduction internal fixation but the patellar tendon rupture was missed and the diagnosis was delayed by 7 months. Patella was migrated proximally. It was moved distally to the original location and neglected patellar tendon rupture treated successfully with modified Ecker technique. Neither preoperative traction nor additional intraoperative procedures were performed to relocate the patella to its anatomic position in the extended knee and good functional result was achieved with intensive rehabilitation.     

Simultaneous and spontaneous bilateral rupture of the patellar tendon in rheumatoid arthritis. A case report.

A case of rupture of the patellar tendon in a patient with rheumatoid arthritis is presented. The age of this patient (27 years) makes this case quite uncommon. The rupture was bilateral, simultaneous and spontaneous. The absence of previous cortisone administration rules out this drug as a cause of the tendon rupture.     

Neglected patellar tendon rupture: preserve the fat pad

Management of neglected patellar tendon ruptures remains a difficult therapeutic endeavor, as complications such as adhesions, proximal patellar migration, and quadriceps contracture occur. Treatment goals include restoration of extensor mechanism, both structurally and functionally, which allows active knee extension. Few cases of neglected patellar tendon rupture have been reported in the literature, however, all have used preoperative or additional intraoperative procedures to relocate the patella or to provide additional support to the reconstructed tendon. This article presents a case of a 25-year-old man whose diagnosis of patellar tendon rupture was delayed by 1 year. The patella was mobile and could be brought down to its original position manually. The patellar tendon was successfully reconstructed with autogenous semitendinosus and gracilis tendon graft. No preoperative or intraoperative traction was used on the patella. Quadriceps lengthening was not performed and no hardware was used between the patella and the tibia to augment the reconstruction. Scar tissue was not excised and was used to cover the hamstring tendons. The patient achieved a good functional result after 5 months of rehabilitation. At 14-month follow-up, the patient had returned to his pre-injury level of work with no deterioration of knee function.     

Simultaneous bilateral patellar tendon rupture without predisposing systemic disease or steroid use: a case report

There is a dearth of case reports describing simultaneous bilateral patellar tendon ruptures in the medical literature.These ruptures are often associated with systemic disorders such as lupus erythema...     

Spontaneous bilateral patellar tendon rupture in an otherwise healthy patient. A case report

Bilateral rupture of the patellar tendons is a rare lesion, usually associated with systemic diseases such as systemic lupus erythematosus, rheumatoid arthritis, chronic renal failure and others. It is extremely rare in a healthy individual, with fewer than 15 cases described. A case of a 32-year-old male with no known history of systemic disease or knee problems is presented. Physical examination, xrays and MRI demonstrated bilateral rupture of the patellar tendons. The tendons were repaired using a nonabsorbable suture reinforced with two titanium anchors fixed to each patella, and a quadriceps tendon flap. The evolution was satisfactory, with both knees recovering a full range of motion in a four-month period.     

Old rupture of the patellar tendon. A case report

A 46-year-old man with pain and instability in the right knee and a long-neglected rupture of the patellar tendon was treated by means of tendon reconstruction. External skeletal fixation between the patella and the tibial tubercle allowed for early exercise of the knee joint, resulting in a favorable range of knee motion. This method is considered to be helpful in the reconstruction of old and disabling patellar tendon ruptures.     

Bilateral spontaneous concurrent rupture of the patellar tendon in a healthy man: case report and review of the literature

Knee extensor mechanism disruption is a serious injury usually requiring emergent treatment. Rupture of the patellar tendon is rare in the normal population; bilateral spontaneous concurrent rupture in a healthy population is an exceptional event. We describe the case of a 39-year-old man with bilateral spontaneous concurrent rupture of the patellar tendon without any underlying systemic disease or drug use.     

Bilateral patellar tendon rupture: case report and literature review.

Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases. We report the case of a 67-year-old man with bilateral ruptures of the patellar tendons caused by minor trauma and with a good functional end result.     

Levofloxacin-induced bilateral Achilles tendon rupture: a case report and review of the literature

We present a rare case of spontaneous bilateral Achilles tendon rupture induced by levofloxacin, one of the fluoroquinolone antibiotics. A 76-year-old man was diagnosed with acute appendicitis and was commenced on oral levofloxacin 300mg/day for 2 weeks. Seven days afterward he developed pain in both Achilles tendons, and at 14 days he developed swelling in the tendons. Four days later he felt a sharp, painful snap in both Achilles tendons while changing trousers. Both Achilles tendons ruptured completely at the mid-portion. There was no obvious underlying disease or pathophysiological factor causing fragility of his Achilles tendons. Despite the relatively large volume of case-based evidence, the pathophysiology of fluoroquinolone-induced tendinitis and tendon rupture is unclear. When tendinitis develops during fluoroquinolone therapy, the physician should consider the possible association between the fluoroquinolone and tendon rupture.

Atraumatic bilateral patellar tendon rupture in a patient receiving steroid therapy

Atraumatic bilateral patellar tendon rupture is a rare entity. It is usually due to systemic or local disorders causing tendon degeneration. Early diagnosis and surgical treatment are crucial for recovery of knee functions. Atraumatic bilateral patellar tendon rupture was diagnosed in a 31-year-old female patient who had been receiving steroid therapy for seven years due to systemic lupus erythematosus. She underwent patellar tendon reconstruction with the use of semitendinosus and gracilis tendons. After a follow-up of six months, she could walk without crutches and had a full range of motion.     

Simultaneous bilateral distal biceps tendon rupture during a preacher curl exercise: a case report

Complete rupture of the distal biceps tendon is a rare injury, the overwhelming majority occurring in the dominant arm of males during the fourth to sixth decades of life. Simultaneous bilateral rupture of the distal biceps tendon is an extremely rare occurrence, with only three cases reported in the literature. This unusual injury occurred in a recreational weightlifter during a preacher curl exercise. In this particular case, a 6-week delay in presentation necessitated a staged procedure in which a primary repair was feasible in one elbow, while reconstruction using allograft tissue was required in the contralateral elbow. Satisfactory results for both elbows were achieved, with return to weightlifting by one year following surgery.
