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...

BACKGROUND Patellar tendinopathy (jumper's knee) is characterized by localized tenderness of the patellar tendon at its origin on the inferior pole of the patella and a characteristic increase in signal intensity on magnetic resonance imaging at this location. However, it is unclear why the lesion typically occurs in this area of the patellar tendon as surface strain gauge studies of the patell...

The aims of the present study were to investigate the ultrasonographic appearance of the patellar ligaments in buffaloes before and after desmotomy. The medial, middle (intermediate) and lateral patellar ligaments, with upward fixation of the patella, were examined ultrasonographically in 12 adult buffaloes before and after medial patellar desmotomy. The results reveal that the ligaments were a...

Arthroscopic reconstruction of the anterior cruciate ligament (ACL) using the middle third of the patellar tendon is an effective method for treating ACL insufficiency. Donor site morbidities are usually mild. This article presents a case of simultaneous patellar fracture and patellar tendon avulsion that occurred 8 weeks after this operation. Such a case has rarely been reported. Theoretically...

From a dental viewpoint, incisor-luxation fractures in horses are fraught with complexities. Luxation fractures are defined as the dislocation of a tooth out of its alveolus without being totally avulsed from the mouth. These are dental emergencies with far-reaching implications. The periodontal and endodontic survival of the involved teeth depends on how these cases are handled. Owners should ...

Luxation of the eye globe is a rare event but it carries a risk of threat to permanent vision loss if appropriate intervention is not initiated on time. Although a rare presentation following minor trauma, it is usually associated with other ocular conditions like shallow orbital socket, floppy eyelid syndrome, and exophthalmos. Prompt reduction results in restoration of full anatomical and vis...

Twenty-four clinically successful, autopsy retrieved porous-coated anatomic total knee arthroplasty (TKA) specimens were evaluated to determine the structure and function of the patellar meniscus. Mean implant duration was 76 months (range: 11-135 months). Histological examination showed the patellar meniscus to be composed of dense fibrous tissue with scattered regions of chronic granulomatous...

Patellar instability has been extensively studied in selected, high-risk cohorts, but the epidemiology in the general population remains unclear. A longitudinal, prospective epidemiological database was used to determine the incidence and demographic risk factors for patellar dislocations presenting to emergency departments of the United States. The National Electronic Injury Surveillance Syste...
