Osgood-Schlatter Disease (OSD) is a painful, growth-related overuse condition of the tibial tuberosity, leading to inflammation of the patellar ligament at the tibial tuberosity. It primarily affects young adolescents, athletic population, and usually, resolves with age or skeletal maturity. Therapy is usually conservative, with surgery indicated in a minority of cases. For patients with treatm...

Aim: To develop a method for closure of the arthrotomy wound and approximation of the medial periosteum at the level of tibial tuberosity after total knee arthroplasty in severe varus deformity. Method: We describe a technique of osteotendinous suturing through the tibial tuberosity for suturing of the medially elevated periosteum. Result: This is an easily reproducible technique which results ...

BACKGROUND The purpose of this study was to quantify the meniscal root anatomy of the New Zealand white rabbit to better understand this animal model for future in vitro and in vivo joint degeneration studies. METHODS Ten non-paired fresh frozen New Zealand white rabbit knee stifle joints were carefully disarticulated for this study. Measurements were made for all bony landmarks and ligamento...

BACKGROUND AND PURPOSE Whether tibial torsion affects the positioning of extramedullary instrumentation and is a possible factor in malalignment of the tibial component in total knee arthroplasty (TKA) is unknown. We assessed the influence of tibial torsion on distal alignment of extramedullary systems for TKA, using the center of the intermalleolar distance as anatomical reference at the ankle...

Stifle trauma can be a common cause of lameness in the athletic horse. Traumatic fractures of the tibial tuberosity and surgical treatment with internal fixation has been previously reported. However, implant failure and catastrophic fracture of the tibia are inherent risks associated with recovery from general anesthesia following repair. To this author’s knowledge, there is no report in the l...

The objective here was to report two rare cases of anterior avulsion fracture of the tibial tuberosity in adolescents. Case 1 was a 15-year-old male who became injured through landing on his left knee and presented limited extension. Case 2 was a 16-year-old basketball player who presented sudden pain in the right knee and functional incapacity, after a jump. Imaging examinations (radiographs a...

BACKGROUND Conventional computed tomography (CT) images are routinely used for diagnosing patellofemoral instability and are obtained with the patient in a supine position, nonweightbearing, with the knee in full extension, and with leg muscles relaxed. A new portable extremity cone beam CT (CBCT) scanner has been developed that may allow for more accurate diagnosis, as imaging can be performed...

The patella is a motorical important part of the feline stifle joint. By gliding proximally and distally inside trochlear groove, its position continually changes during each step mobility. Stifle diseases like patellar luxation, cruciate ligament rupture, or tendon disease as well consecutive surgical interventions may cause dislocation.

OBJECTIVE To identify the anatomical motor points of the abductor hallucis muscle in cadavers. METHODS Motor nerve branches to the abductor hallucis muscles were examined in eight Korean cadaver feet. The motor point was defined as the site where the intramuscular nerve penetrates the muscle belly. The reference line connects the metatarsal base of the hallux (H) to the medial tubercle of the...

The importance of a dysplastic trochlea as a component of patellar instability (especially recurrent dislocation or habitual dislocation) has been recognized for many years. It is usually combined with other static or dynamic abnormalities, such as genu recurvatum, patella alta, patellar tilt, increased Q angle, and bone torsional abnormalities. Major trochlear dysplasia is characterized by the...
