Anteromedialization of the tibial tuberosity is a new and highly effective technique for transferring the tibial tuberosity when anteriorization is desired in addition to medial shift of the patellar tendon insertion. Prompt primary bone healing can be achieved, allowing rapid rehabilitation with substantially improved patellofemoral mechanics. No bone(More)
The patient-athlete with patellofemoral pain requires precise physical examination based on a thorough history. The nature of injury and specific physical findings, including detailed examination of the retinacular structure around the patella, will most accurately pinpoint the specific source of anterior knee pain or instability. Radiographs should include(More)
This retrospective study determined that the outcome from anteromedialization of the tibial tubercle correlates well with the location of patellar articular lesions. Detailed descriptions of patellar articular cartilage lesions were obtained from the operative reports of 36 patients who had anteromedialization performed between February 1984 and March 1994.(More)
Computerized tomography (CT) provides an accurate diagnostic tool for evaluating tilt and subluxation of the patella. Using a previously described technique, this study reviews 62 computerized tomograms, including those of 21 patients before and after lateral release or anteromedial tibial tubercle transfer. One patient was evaluated before and after(More)
In this study of bioabsorbable screw fixation of free tendon grafts used in anterior cruciate ligament reconstruction, we performed load-to-failure and cyclic loading of tendon fixation in porcine bone. Bone density measurements from dual photon absorptometry scans were obtained to correlate bone density with fixation failure. The average density of porcine(More)
There are well-recognized limitations of conventional axial radiographs of the patellofemoral joint in assessing patients with peripatellar pain, particularly in the first 20 degrees of knee flexion. Computerized tomography (CT) was used, therefore, to evaluate 20 patients with persistent patellofemoral pain and ten asymptomatic volunteers. Multiple(More)
All new patients who presented with knee problems were asked to fill out standard knee pain diagrams before being evaluated. Completed diagrams were not seen by the examining physicians. After obtaining the history and performing the physical examination, one of four physicians marked an identical diagram with the areas of tenderness. Ninety patients with a(More)
There are clear differences between men and women regarding anterior knee pain. Anatomic factors including increased pelvic width and resulting excessive lateral thrust on the patella are primary factors that predispose females to anterior knee pain. Effects of estrogen on connective tissue synthesis have been reported, but there is no clear mechanism by(More)
This is a retrospective study of one surgeon's experience performing anteromedialization of the tibial tubercle for the treatment of isolated patellofemoral arthritis in active older patients. Patients were included if they were > 50 years at the time of the surgery and had a minimum follow-up of 2 years. Outerbridge classifications were documented by(More)
