CONCLUSION: Osteochondral fractures were detected by plain radiography in 10% of patients presenting with lateral patellar dislocation and did not alter ED management. [ncbi.nlm.nih.gov]

• Soft Tissue Mass

  MRI revealed an intra-articular soft tissue mass at the lateral gutter of the knee joint with considerable mass effect displacing patella from the trochlear groove. [ncbi.nlm.nih.gov]

• Arachnodactyly

  Two siblings were affected with almost identical features; including blepharophimosis, arachnodactyly, flexion contractures of the elbows, camptodactyly, slender ribs, hooked lateral clavicular ends, and bilateral radial head dislocations. [ncbi.nlm.nih.gov]

• Dysostosis

  This disease causes many skeletal changes including dysostosis multiplex, synovial hypertrophy, and Charcot-type joints. [ncbi.nlm.nih.gov]

• Prognathism

  In addition to the already described macrocephaly and mild ID, they share osteoarticular defects, patella dislocation, behavioral abnormalities, psychosis, learning difficulties, celiac disease, prognathism, myopia, and astigmatism. [ncbi.nlm.nih.gov]

• Flexion Contracture

  We present a case of an 8-year-old boy diagnosed with melorheostosis who was suffering from severe genu valgum, permanent dislocation of the patella, knee flexion contracture and leg length shortening. [ncbi.nlm.nih.gov]

  contracture should be 5o Angular deformity should be 15 o (10 o varus to 15 o valgus) and be passively correctable to neutral Both cruciates should be intact Final decision to proceed after inspection of the joint surfaces Patello femoral joint pain [flinders.edu.au]

  Quadriceps muscle weakness can be expected to occur post-operatively. 2015 The British Editorial Society of Bone & Joint Surgery. [ncbi.nlm.nih.gov]

• Joint Deformity

  Soft tissue contracture of the limb and subsequent joint deformities were reported to represent clinical manifestations of pediatric melorheostosis. [ncbi.nlm.nih.gov]

• Macrocephaly

  In addition to the already described macrocephaly and mild ID, they share osteoarticular defects, patella dislocation, behavioral abnormalities, psychosis, learning difficulties, celiac disease, prognathism, myopia, and astigmatism. [ncbi.nlm.nih.gov]

• Learning Difficulties

  In addition to the already described macrocephaly and mild ID, they share osteoarticular defects, patella dislocation, behavioral abnormalities, psychosis, learning difficulties, celiac disease, prognathism, myopia, and astigmatism. [ncbi.nlm.nih.gov]

A workup typically includes X-rays and may require additional testing such as an MRI or CT scan to fully define the injury, and determine why the patient had the injury, if risk factors are present. [trihealth.com]

Two common treatment options include nonoperative treatment or operative repair of injured structures. [ncbi.nlm.nih.gov]

Prognosis Most people recover full function following a course of conservative care of physical therapy to strengthen and stabilize the knee. [twinboro.com]

What is the Prognosis of Kneecap Dislocation? The prognosis of Kneecap Dislocation is usually good, if appropriate medical treatment is provided. [dovemed.com]

What Is the Prognosis of a Knee Dislocation? In general, this is a very serious injury. Recover is possible, but often the injured knee does not regain its previous capacity to adsorb stresses. [emedicinehealth.com]

A MRI is necessary to assess for osteochondral lesions, as they are associated with a poor prognosis if not addressed. [physio-pedia.com]

Etiology, diagnosis and treatment are discussed. Arthroscopy is recommended to visualize chondral defects. Results are presented in combination with follow-up. Four patients still complain of instability of the knee after surgery. [ncbi.nlm.nih.gov]

Another cause of patellar symptoms is lateral patellar compression syndrome, which can be caused from lack of balance or inflammation in the joints. [8] The pathophysiology of the kneecap is complex, and deals with the osseous soft tissue or abnormalities [en.wikipedia.org]
