Anterior knee pain and/or radiological evidence of degeneration of the patellofemoral joint are considered to be contraindications to unicompartmental knee replacement. The aim of this study was to determine whether this is the case. Between January 2000 and September 2003, in 100 knees (91 patients) in which Oxford unicompartmental knee replacements were undertaken for anteromedial osteoarthri...

medialis obliquus, is the main passive stabilizer of the patellofemoral joint. Recently, it has been shown that the medial patellofemoral complex is the main pathoanatomy after patellar dislocation [1-3] . In addition, biomechanical studies have demonstrated that the MPFL is the main restraint against lateral patellar displacement and that repair or reconstruction of the MPFL restores normal pa...

PURPOSE the aim of this article was to review the clinical approach of quadriceps strengthening programmes. METHODS a literature search was carried out from 1980 up to September 2011. Eligible studies were those that: (1) evaluated the patients with patellofemoral pain syndrome (not healthy or asymptomatic subjects) (2) examined the effect of kinetic chain exercises (3) examined the effect of...

BACKGROUND Significant correlation has been previously demonstrated between radiographic and clinical diagnoses of knee osteoarthritis (OA); however, the specific findings on clinical examination that relate best to a radiographic diagnosis have not been fully elicited. AIMS We aimed to explore the relationship between clinical symptoms and physical findings with radiographic diagnoses of tib...

Patellofemoral instability is related to anatomy. Magnetic resonance imaging (MRI) provides anatomic detail, but spoiled gradient echo (SPGR) imaging during isometric quadriceps contraction provides objective functional data for diagnosing patellofemoral laxity. Knee MRI studies and medical charts of 398 patients were retrospectively reviewed. Two independent blinded observers evaluated the kne...

OBJECTIVE To determine the differences in load-bearing patellofemoral joint cartilage thickness between genders. To determine the differences in load-bearing cartilage thickness between pain-free controls and individuals with patellofemoral pain. METHODS The articular cartilage thickness of the patella and anterior femur was estimated from magnetic resonance images in 16 young, pain-free cont...

This prospective study determined whether selected anatomic measures identified women at increased risk of patellofemoral pain syndrome (PFPS) and shin splints (SS). Ten anatomic measures were performed on 748 women before basic training at the Marine Corps Recruit Depot (MCRD), Parris Island, South Carolina. Recruits were then followed throughout basic training for occurrence of injuries. Logi...

Introduction: Patients with patellofemoral instability with trochlear dysplasia may be treated with trochlear osteotomy. Case presentation: We present a patient with patellofemoral instability treated with trochlear osteotomy. The procedure resulted in nonunion with painful bony impingement and isolated patellofemoral osteoarthritis. Patellofemoral arthroplasty was performed. Conclusion: Patell...

BACKGROUND The treatment of isolated patellofemoral arthritis is controversial. Several surgical procedures have been used to treat the severely degenerated patellofemoral joint, with varying degrees of success. The purpose of this study was to determine the clinical results of a custom patellofemoral arthroplasty for the treatment of isolated patellofemoral degenerative arthritis of the knee. ...

OBJECTIVE To evaluate the patellar height of volunteers with and without patellofemoral pain syndrome (PPS) during maximal voluntary isometric contraction (MVIC) in open kinetic chain (OKC) and closed kinetic chain (CKC) exercises. METHODS Twenty healthy women, and nineteen women with patellofemoral pain syndrome were evaluated and subjected to nuclear magnetic resonance imaging during rest a...
