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]

• Gagging

  The results from quantitative MRI of the patellar cartilage indicate changes in both GAG content and collagen structure. [openarchive.ki.se]

• 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]

• Long Legs

  Long-leg standing radiographs showed an anatomic tibiofemoral angle of right 13° and left 6° valgus and a mechanical tibiofemoral angle of right 8° and left 2° valgus and weight-bearing line of 65% on the right and 48% on the left. [ncbi.nlm.nih.gov]

  […] slightly abducted, the other hand is placed on the lat side of the leg at the level of the fibular head- applying a valgus thrust to the leg and gently flexing it if +ve, subluxation will occur at 20-30 o with the lat fem condyle sliding forward on the [flinders.edu.au]

  In a series of 36 patients, Piodarino et al. reported one case of tibia fracture requiring 2 months in a long leg cast and one case of arthrofibrosis that improved followed closed manipulation under anaesthesia 5 months after surgery [ 53 ]. [oapublishinglondon.com]

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]

For this reason, low-velocity dislocations have a more optimistic prognosis than high-velocity dislocations. Knee Dislocation Symptoms There are several possible signs and symptoms that manifest when a knee is dislocated. [sgbonedoctor.com]

Prognosis of PFPS In younger patients, if appropriate action is taken at an early stage, exercise adjusted accordingly and the quadriceps muscles built up then the outlook for full functional recovery is very good. [patient.info]

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]

RESULTS: Tibial tubercle distalization was generally successful in normalizing patellar height and preventing recurrent patellar dislocation. [ncbi.nlm.nih.gov]

To prevent this from happening a surgeon can cut through the tightest aspects of the capsule. This will prevent it from pulling your patella too hard to the outer side. This procedure is only done when conservative treatment didn’t work. [alwaysfysio.nl]

Surgical procedures include: Arthroscopic repair of damaged cartilage, or to realign ligaments or tendons that stabilize the patella Reconstruction of medial patellofemoral ligament to help with stability and prevent recurrent dislocations Prevention [winchesterhospital.org]
