- Pain
Inclusion criteria were age 18–50 years and anterior knee pain or instability of at least 6 months’ duration. [dovepress.com]
Signs and symptoms [ edit ] Symptoms usually include: [3] Knee buckles and can no longer support your weight Kneecap slips off to the side Knee catches during movement Pain in the front of the knee that increases with activity Pain when sitting Stiffness [en.wikipedia.org]
Physical therapy is recommended which helps to control pain and swelling, prevent formation of scar of sof t tissue, and helps in collagen formation. [njorthoinstitute.com]

Patients should be discharge home on crutches with simple analgesia for pain control. [lifeinthefastlane.com]
- Weakness
Her history is atypical in that after her fifth dislocation, her recovery was hindered secondary to persistent weakness and atrophy of her quadriceps out of proportion to disuse alone. [ncbi.nlm.nih.gov]
Finally, weak core musculature and weak hip muscles can decrease the muscular control an athlete has over their entire lower extremity including the knees. [sportsmd.com]
- Falling
In this case, a 53-year-old woman sustained a locked lateral patellar dislocation when falling from a chair. [ncbi.nlm.nih.gov]
This condition usually results from a twisting injury or a direct blow, with the knee in slight flexion. the injury is painful and may cause the patient to fall to the ground commonly seen in the second and third decade of life and often in women (1) [gpnotebook.co.uk]
The kneecap, or patella, serves as armor that protects the joint from falls and other types of damage. Patellar dislocation is a condition where the kneecap becomes misaligned. [vivehealth.com]

- Surgical Procedure
RESULTS: The medial stiffness of the affected side before the surgical procedure was significantly lower than the lateral stiffness (p = 0.004) and the stiffness for healthy reference knees (p = 0.004). [ncbi.nlm.nih.gov]
Patella stabilisation is a surgical procedure used in the treatment of conditions such as patella subluxation and patella dislocation. [physio.co.uk]
- Inflammation
However, if the injury and subsequent inflammation is not resolved, inflammation can become a chronic issue, leading to further inflammation and additional injury. This cycle of inflammation leads to continued or progressive knee pain. [webmd.com]
After an injury, inflammation invades the knee, which causes further injury, and further inflammation, and so on. This cycle of inflammation leads to continued or progressive knee pain. [emedicinehealth.com]

She re-presented 2 months later with ipsilateral knee pain after climbing a step. The initial diagnosis was quadriceps tear and ultrasound confirmed a partial tear in proximal vastus medialis. [ncbi.nlm.nih.gov]
- Genu Valgum
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]
Patellar dislocation usually occurs spontaneously following torsion of a semiflexed knee and is typically the result of underlying biomechanical abnormalities such as hyperlaxity of the medial patellofemoral ligament, high-riding patella, genu valgum, [amboss.com]
- Muscle Weakness
She experienced muscle weakness after the initial injury and developed neuropathic symptoms through the anterior left thigh. [ncbi.nlm.nih.gov]
Children with cerebral palsy and Down syndrome may have kneecaps that dislocate frequently due to imbalance and muscle weakness. Rarely, children are born with unstable kneecaps causing dislocations at a very early age, often without pain. [orthoinfo.aaos.org]

- Joint Dislocation
Some people are more prone than others to dislocation. Which are the most common joint dislocations? Most joints in the body can be dislocated but some are dislocated more commonly than others. [patient.info]
There are different degrees of instability that occur in the knee, like dislocation. When referring to knee dislocation, we are referring primarily to the patellarfemoral joint. [twinboro.com]

Permanent post-traumatic dislocation of the patella is an extremely rare condition, and is often confused with congenital dislocation. [ncbi.nlm.nih.gov]

Not to be confused with the trochlear spur (discussed below), the trochlear bump measurement assesses the most anterior extent of the trochlear floor, measured relative to a line drawn along the most distal 10 cm of the anterior cortex of the femoral [radsource.us]
These differences in definition area permanent source of confusion in the literature, making it most difficult toproperly interpret reported results. [em-consulte.com]
Workup
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]
Treatment
Surgical Treatment for Patella Dislocation/Subluxation Surgical treatment is recommended for those individuals who have recurrent patella dislocation. [njorthoinstitute.com]
Two common treatment options include nonoperative treatment or operative repair of injured structures. [ncbi.nlm.nih.gov]

Prognosis
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]

Pathophysiology
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]
