Is the wrinkled wall syndrome the same as patellar locked dislocation?

Hello, Dr.
Fan: Is surgery the only option for the diagnosis of (wrinkled wall syndrome)? Additionally, the orthopedic doctor at the National Defense Medical Center 804 Hospital diagnosed it as (patellar dislocation with bony impaction).
Are these two conditions the same in terms of symptoms and location? After surgery, what precautions should be taken? Is there a chance of recurrence? Thank you for your professional advice!

Hello, regarding your question, here is the response:
1.
Plica syndrome and patellar instability are different conditions and diagnoses.
Plica syndrome: The knee does not cause pain under normal use, but prolonged friction between the articular cartilage can lead to inflammatory responses (e.g., bursitis), which affects joint function.
Over time, repetitive friction and inflammation can cause the plicae to fibrose and thicken, becoming trapped between the patella and the medial femur, resulting in pain and symptoms such as sudden weakness or giving way when walking or climbing stairs.
Clinical examination may reveal localized tenderness in the knee joint, and a crackling sound may be felt when bending the knee.
If there is pain and swelling, treatment usually involves rest, ice application, and oral medications to control inflammation.
Physical therapy can generally alleviate most inflammatory conditions; however, if symptoms do not improve effectively, arthroscopic surgery may be required to remove chronic inflammatory tissue.
2.
Patellar instability refers to the condition of patellofemoral instability, which includes a range of issues from abnormal movement of the patella (kneecap) over the distal femur to recurrent subluxation and dislocation of the patella.
Patellar instability typically occurs laterally, while medial instability is extremely rare.
Uneven stress on the patellar ligaments and tendons can cause the patella to tilt laterally or predispose it to dislocation.
The causes of patellar dislocation are often due to indirect trauma, although direct impact injuries can also occur.
Acute treatment involves compressive bandaging of the injured knee joint or using a splint for protection.
If there is swelling in the joint, aspiration may be performed to relieve pain.
Cold therapy should be applied within 24 to 48 hours, along with analgesics and anti-inflammatory medications.
Although the patient is in a splint, they can still perform isometric exercises for the thigh muscles, and reevaluation should occur every two weeks.
The splint should ideally be used for six weeks, and as pain on the medial side of the knee decreases, strengthening exercises and range of motion activities should be initiated promptly.
If loose bodies (fragments of cartilage) remain in the joint after injury, they can be surgically removed.
Initial treatment for chronic patellar ligament and tendon uneven stress should focus on strengthening and improving joint mobility, and using a knee brace can help the patient return to work or sports.
Sometimes physical therapy, such as electrical stimulation or massage, may be effective.
If conservative treatment fails, surgical intervention, such as patellar ligament reconstruction, may be considered.
The outcomes of the surgery are generally favorable, requiring only a short period of rehabilitation for recovery.
Thank you for your inquiry!

Wrinkled Wall Syndrome (WWS) and Patellar Dislocation are distinct medical conditions, each with its own pathophysiology, symptoms, and treatment approaches. Understanding the differences between these two conditions is crucial for effective diagnosis and management.

Wrinkled Wall Syndrome primarily involves the knee joint, where chronic friction between the joint surfaces leads to inflammation and the thickening of the synovial tissue. This condition can result in pain, swelling, and functional limitations, particularly during activities such as walking or climbing stairs. The symptoms may include localized tenderness, a "crackling" sound during knee movement, and episodes of weakness in the leg. Initial treatment often involves conservative measures such as rest, ice application, anti-inflammatory medications, and physical therapy. If these methods fail to alleviate symptoms, arthroscopic surgery may be necessary to remove the inflamed tissue.

On the other hand, Patellar Dislocation refers to the instability of the patella (kneecap), which can either partially dislocate (subluxation) or completely dislocate from its normal position on the femur. This condition is often characterized by acute pain, swelling, and a visible deformity of the knee. Patellar dislocation can occur due to direct trauma or as a result of anatomical predispositions, such as abnormal alignment of the knee joint. Treatment for patellar dislocation typically begins with conservative measures, including immobilization, ice, and anti-inflammatory medications. Rehabilitation focuses on strengthening the muscles around the knee and improving stability. In cases of recurrent dislocations or significant structural abnormalities, surgical intervention may be required to realign the patella and stabilize the joint.

Regarding your question about surgical intervention, both conditions may require surgery if conservative treatments are ineffective. However, the specific surgical procedures and recovery protocols differ based on the underlying pathology. After surgery, it is essential to follow your orthopedic surgeon's post-operative care instructions, which may include physical therapy, gradual return to activities, and monitoring for signs of complications such as infection or re-injury.

As for the risk of recurrence, both conditions can have varying outcomes. In the case of WWS, if the underlying causes of inflammation and friction are not addressed, symptoms may recur. For patellar dislocation, the risk of re-dislocation can be higher, especially if there are anatomical factors contributing to the instability. Engaging in a structured rehabilitation program and adhering to preventive measures can significantly reduce the likelihood of recurrence.

In summary, while Wrinkled Wall Syndrome and Patellar Dislocation may present with some overlapping symptoms related to knee pain and dysfunction, they are fundamentally different conditions requiring tailored treatment approaches. If you have been diagnosed with either condition, it is crucial to work closely with your healthcare provider to develop an appropriate management plan that addresses your specific needs and circumstances.
