BACKGROUND Recurrent dislocation of the patella in patients with below knee amputation is a known entity. Abnormally high-riding patella (patella alta) and medial patellofemoral ligament insufficiency in these patients predisposes them to patellar instability. The established treatment of this problem is surgical realignment. CASE PRESENTATION A 25 year old male patient with bilateral below k...
The purpose of this study was to test the hypothesis that patella alta leads to a less favourable situation in terms of patellofemoral contact force, contact area and contact pressure than the normal patellar position, and thereby gives rise to anterior knee pain. A dynamic knee simulator system based on the Oxford rig and allowing six degrees of freedom was adapted in order to simulate and rec...
Objective—To determine whether tissue angiotensin converting enzyme (ACE) is increased in synovia from patients with rheumatoid arthritis, osteoarthritis or chondromalacia patellae. Methods—Sections of synovia from patients with rheumatoid arthritis (n = 7), osteoarthritis (n = 7) or chondromalacia patellae (n = 6) were tested for immunoreactivity for ACE, and for binding of the ACE inhibitor [...
OBJECTIVE The objective of this study was to describe the arthroscopic findings of chondromalacia and its relation with the internal derangement of the temporomandibular joint (TMJ). PATIENTS AND METHODS A total of 161 patients (299 TMJs) who underwent arthroscopy were included in the study. The TMJs were evaluated objectively under arthroscopic vision, and 4 groups of patients were establish...
A lowering of the patella after total knee arthroplasty is accompanied by pain and a restriction of the range of motion. With its etiology being unclear at present, a multifactorial genesis is under discussion. For the first time, we present a case report describing an HIV infection as a possible cause of patella infera.A 54-year-old HIV-positive woman developed patella infera (Insall-Salvati r...
BACKGROUND Patellar crepitus may occur with posterior-stabilized (PS) TKAs. Several studies have suggested numerous etiologies of patellar crepitus after PS-TKA with patellar resurfacing. However, it is unclear whether and to what degree crepitus influences pain and function without or with patellar resurfacing. QUESTIONS/PURPOSES We therefore determined (1) the frequency of crepitus; (2) whi...
The purpose of this study is to determine if patellar maltracking is more prevalent among patellofemoral (PF) pain subjects with patella alta compared to subjects with normal patella height. We imaged 37 PF pain and 15 pain free subjects in an open-configuration magnetic resonance imaging scanner while they stood in a weightbearing posture. We measured patella height using the Caton-Deschamps, ...
A retrospective study of 4 cases of frostbite was undertaken to examine causes and to identify related contributory behaviors and circumstances. These patients underwent various surgical interventions before the onset of frostbite during similar postoperative care regimens. Surgical procedures included some of the following in each patient: lateral retinacular release, vastus medialis oblique m...
