The patella is the largest sesamoid bone in the body. As the patella bone is responsible for the strong extensor mechanism of the knee joint, its reconstruction and anatomical restoration after fracture is always desirable over excision. Extra articular fracture of lower pole of patella accounts for less than 10 percent of all patellar fractures. The treatment of these fractures is complicated,...

INTRODUCTION Patellar tendon rupture can occur due to multiple causes ranging from inflammatory pathologies to episodes of trauma. Extensor mechanism rupture is a rare complication of total knee arthroplasty (TKA). In most of these cases, the failure occurs as avulsion of patellar tendon from tibial tuberosity. We report a rare case with bilateral mid-substance patellar tendon rupture one month...

A 58-year -old man with a past history of acquired emphysema was admitted after his legs 'gave way' as he walked down a short flight of steps. He was unable to extend either knee actively. Bilateral patellar tendon ruptures were diagnosed clinically from the history, and the finding of swelling and a palpable gap below the lower pole of each patella. The diagnosis was confirmed radiologically (...

We present an exceedingly rare case of spontaneous bilateral patellar tendon rupture in a fit and well 38year-old Afro-Caribbean gentleman regularly participating in recreational long-distance running. Prior to sustaining this injury, he complained of ongoing anterior knee pain, for which he was awaiting an outpatient X-ray arranged by his general practitioner after weeks of anti-inflammatory m...

Atraumatic patellar fractures after Total Knee Arthroplasty (TKA) are rare in unresurfaced patella. Previous reports are few and have highlighted association of these fractures with rheumatoid arthritis and gout along with interference with patellar blood flow after lateral release and Hoffas’ fat pad excision. We report a case of insufficiency fracture of patella in a patient following TKA aft...

conclusions surgical treatment for patellar dislocation is indicated primarily in case of relevant concomitant injuries such as osteochondral fractures, and secondarily for recurrent dislocations. evidence acquisition authors searched the medline library for studies on both surgical and conservative treatment for patellar dislocation and patellofemoral instability. additionally, the reference l...

Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consi...

Orthopedic surgeons resurface the patella during total knee arthroplasty to avoid complications such as pain, patello-femoral arthritis, and patellar maltracking and to reduce the risk for reoperation. However, many complications, such as decreased range of motion, increased fractures, and polyethylene wear, have been described with this procedure. One determinant when resurfacing a patella is ...
