We present a case of a patient with chronic anterior knee pain (AKP) recalcitrant to conservative treatment who returned to our office for severe hip pain secondary to Cam femoroacetabular impingement (Cam FAI) at 10 months after the onset of knee pain. This case highlights the fact that the main problem is not in the patella but in the hip in some patients with AKP. We hypothesize that there i...

Patellofemoral pain (PFP) is a common knee disorder in orthopedic clinics. In the last decade, several investigations have considered the role of proximal factors in addition to local and distal factors in development of PFP. There is a hypothesis which suggests that impaired neuromuscular control and altered hip joint kinematic affect tibiofemoral and patellofemoral biomechanics. Hence, PFP ma...

Anterior knee pain is a frequent clinical problem. It provides a common challenge to diagnose and manage. Basic science studies have provided insight into the origin of anterior knee pain and refined understanding of the anatomy. Clinical evaluation has progressively focused on the contribution of the entire lower extremity to patellofemoral function. Nonsurgical management has been refined by ...

Patellofemoral pain is common in both athletic and nonathletic individuals. It is observed in 15%–33% of the young active group and approximately in 21%–45% in adolescence. Among athletes, men tend to present with more patellofemoral injuries than women. In the nonathletic population, women and young individuals more commonly present with patellar disorders. Many static and dynamic internal der...

CONTEXT Patellofemoral pain syndrome (PFPS) is a common orthopaedic condition for which operative and nonoperative treatments have been used. Therapeutic modalities have been recommended for the treatment of patients with PFPS-including cold, ultrasound, phonophoresis, iontophoresis, neuromuscular electrical stimulation, electrical stimulation for pain control, electromyographic biofeedback, an...

OBJECTIVE To retrospectively assess the early results of the NexGen Legacy posterior-stabilised total knee prosthesis, which is a newer version of the Insall-Burstein II posterior-stabilised implant. METHODS 48 consecutive elderly patients had 60 NexGen Legacy posterior-stabilised total knees. The mean follow-up duration was 21 months. Clinical evaluation was performed according to the Knee S...

The purpose of this study was to investigate the shortand long-term effect of leg-press exercises in dealing with patellofemoral pain. Sixty subjects with patellofemoral pain participated. They were randomly assigned into leg-press exercise or control (no exercise) group. Training consisted of three weekly sessions for eight weeks. Measurements of pain (VAS), Lysholm scale score, morphology of ...

BACKGROUND Anterior knee pain may occur after total knee arthroplasty (TKA). Patellar resurfacing, which is considered to lower the incidence of anterior knee pain after TKA, remains controversial. In the present study clinical and radiological outcomes after TKA performed on patients with clinical and radiological signs of femorotibial and patellofemoral osteoarthritis (OA) with and without pa...

Although wearing high-heeled shoes has long been considered a risk factor for the development for patellofemoral pain (PFP) in women, patellofemoral joint kinetics during high-heeled gait has not been examined. The purpose of this study was to determine if heel height increases patellofemoral joint loading during walking. Eleven healthy women (mean age 25.0±3.1 yrs) participated. Lower extremit...

Because we communicate mainly through words, it is important that terms be understood in the same manner by all readers. Unfortunately, the study of the patellofemoral joint is complicated by the use of expressions that hold different meanings for different readers. Ideally, the community of musculoskeletal physicians should agree on a single definition of terms, but until then, authors and spe...
