Knee joint lateral retinaculum
Common Questions and Answers about Knee joint lateral retinaculum
knee
Hello and Welcome,
I am sorry to hear about your knee pain. I personally know how disruptive knee pain can be to our daily life.
For our members VMO stands for vastus medialis oblique and is part of the vastus medialis quadriceps muscle at the front of the thigh. It is an active and dynamic stabiliser of the patella (knee cap). The VMO stabilizes the patella within the patella groove. It also controls the tracking of the patella when the knee is bent and straightened.
- Lateral Meniscus: There is minimal blunting of the body of lateral
meniscus as seen on image 9:21.
- Cartilage: There is a focal area of full-thickness cartilage defect of
the articular surface of tibial plateau as seen on image 9:21. Also seen
is mildly increased signal in the articular cartilage in keeping with
chondromalacia with few areas of partial-thickness cartilage loss.
- Lateral collateral ligament: The lateral collateral ligament is intact.
A Baker’s cyst or a popliteal cyst is a swelling caused by collection of synovial fluid which has escaped from the knee joint, protruding in the area which is back of the knee. Check if you have a baker's cyst?
The treatment for Baker’s cyst includes rest, keeping your leg propped up for several days, massage treatments by a physiotherapist, compression wraps/elastic bandage, NSAIDs and cortisone injections. It may even recede on its own. If not consider surgical treatment.
Take care!
No acute fracture or joint dislocation is identified involving the left knee. Bones of the left knee do appear somewhat under mineralized relative to the right knee. Areas of sclerosis within the lateral tibial plateau and lateral femoral condyle are demonstrated, as well as within the distal femoral metaphysis. One or all of these sclerotic foci may represent sequelae of avascular necrosis given reported history. No significant joint space narrowing is identified.
Anterior Horn Diminutive, ACL Diminutive, Stable Chondral degeneration grade 1, grade 2 Medial Joint, Chondral thinning grade 2 and grade 3 posterior aspect Lateral Tibial Plateau, Patchy Bone Marrow Edema in Lateral Femoral Condyle, Small joint effusion with synovitis, joint effusion Patella, Chondral degeneration Patella, Trochlear Groove Cartilage Grade 2, some edematous medial and posterior capsules, tendinopathy.
Ever since then, I have had a bad, achy pain in the right side of my knee on the joint line, especially when standing and I pick my foot up. The worst pain is when I rotate my toes outward with my knee bent. It occasionally hurts when decelerating, and definitely when going down stairs. I got an MRI today and am waiting the results, but does this sound like a tear? I know it's not large since the knee hasn't locked, but I do feel a small pop on that side of my knee when I straighten it.
MRI of knee shows "irregularity and hyperense signal in root of lateral meniscus , popliteal fossa cysts, small bakers cyst, myxoid degeneration in lateral meniscus and posterior horn of medial meniscus." ( also mild chondromalacia patella??)
Physician is reccommending arthroscopic surgery.... does this sound reasonable??
You likely have bruised meniscus. These are the shock absorbers in the knee (two per knee, medial and lateral, medial inside, lateral outside). Good policy is to give every muscle and joint one day of rest for every day practicing/training. You can work out every day, but work different things. Wait 3 days and if it still hurts see a doctor. Skip your PCP if you can and go to an Ortho. Sounds to me like you'll be fine with rest...
Tiny toci of ill-defined marrow edema are seen in the medial and lateral femoral condyles and lateral tibial plateau. No discrete fracture is identified. A small joint effusion is present.
IMPRESSION: Left patellar chondromalicia, including partial thickness cartilage fissuring with formation of cartilage flap at the junction between the patellar apex and medial facet.
There is a defect in the cartilage covering the surface of the thigh bone that forms the knee joint and a similar defect in the bone of the lower leg with associated degenerative/ inflammatory changes. There are two small body bodies seen within the joint with increased fluid in the joint space.
Hope this helps.

There is mild intermediate intensity intrasubstance signal within the menisci but no discrete tear evident extending to an articular surface. The medial and lateral compartment hyaline cartilage appears preserved. With the knee in extension there is lateral patellar tilt with approximate 3mm lateral patellar subluxation. Probably mild fibrillation hyaline cartilage patellofemoral compartment predominantly lateral. Patellar retinacula are intact. Marrow signal is normal.
m a 46yo fem skier symptoms of joint line pain and stiffness in the right knee. No locking or serious instability although the knee has given a couple of times.
18years prior I had a broken tibial plateau that required bone graft (freeze dried cadaver bone) with 2 screws and meniscus repair on the lateral side. Screws were taken out and the plateau had to be reshaped on both the lateral and medial sides to due excess bone growth from the repair. I've been skiing ever since.
The other area in which there is cartilage loss in at the outer part of the main thigh bone at the knee joint. However the rest cartilage disc in between the knee joint appear normal from this report. With regards to treatment, a lot of decisions are based on the clinical picture - how much this is affecting you and your activities and what the knee is like on examination. I hope this has been of some help and has answered your questions.
