Recurrent patellar instability can result from osseous abnormalities, such as patella alta, a distance of >20 mm between the tibial tubercle and the trochlear groove, and trochlear dysplasia, or it can result from soft-tissue abnormalities, such as a torn medial patellofemoral ligament or a weakened vastus medialis obliquus.

Bracing for Patellar Instability
Clinics in Sports Medicine, 1990Knee pain secondary to problems with patellar tracking is common. The initial treatment for these problems is conservative. Patellar orthotics have been used extensively to treat a variety of extensor mechanism problems. Millions of health care dollars are spent annually on the use of these braces.

What activities do patients with patellar instability perceive makes their patella unstable?
Knee, 2011 Patellar instability is a disabling musculoskeletal condition. Whilst previous texts have suggested that twisting activities may cause patients to experience instability symptoms, no studies have assessed which activities are related to the patient's ...

Patellar Instability in Young Athletes
Clinics in Sports Medicine, 2022This article summarizes the latest research related to pediatric patellar instability. The epidemiology, patterns of patellar instability, and underlying pathoanatomy are unique in children and adolescents. Information related to the natural history and predictive factors of patellar instability in young patients would allow for better patient ...

Patellar tendon length — the factor in patellar instability?
The Knee, 2002Patellar tendon length has been compared in 42 knees with a history of patellar dislocation, and 51 control knees. A lateral X-ray and a magnetic resonance image (MRI) were taken of each knee. The mean radiological patellar tendon length was 46 mm in the controls and 53 mm in the dislocation group. From MRI images, the mean was 44 mm in controls and 52

Lateral Patellar Retinaculum Tension in Patellar Instability
Clinical Orthopaedics and Related Research, 2002The patellar retinaculum is important in patellar tracking. However, little attention has been paid to the biomechanics of the retinaculum. This study assessed the change in tension of the lateral patellofemoral ligament before and after anteromedial tibial tubercle transfer for patellar instability.

Patellar fracture following surgery for patellar instability
The Knee, 2004We present a case of patellar fracture in a teenager that followed a soft tissue realignment surgery for patellar instability. We propose that this fracture was due to disruption of the blood supply to the patella as a result of the procedure. To our knowledge this complication, which has been documented following Total Knee Arthroplasty, has not been ...

The inferomedial patellar protuberance and medial patellar ossicle in patellar instability
Knee Surgery, Sports Traumatology, Arthroscopy, 2015The purpose of the study was to define the frequency of an inferomedial patellar protuberance in patients presenting to a specialist Patella Clinic and to characterise the clinical and radiological features as well the association between the inferomedial patellar protuberance and the medial patellar ossicle.A cohort of 163 patients (166 knees) was ...

Nonoperative Treatment of Patellar Instability
Sports Medicine and Arthroscopy Review, 2017The treatment of patellar instability is challenging and typically begins with nonoperative methods. Clinical decisions are made on an individual basis and may vary according to a number of factors. First-time patellar dislocations most commonly occur during sports participation.
