Intrasubstance/incomplete tear (top left) This type of tear is often a sign of degenerative changes in the meniscus tissue. These injuries have been reported to change joint loading due to failure of the meniscus to convert axial loads into hoop stresses. Steroid injection. Tears to the medial meniscal root change the biomechanics and kinematics of the knee, which cause early degeneration of the joint. The treatment of these type of tears can be either arthroscopy (surgery through a tiny hole in knee) or conservative. 2nd edn. Barrett GR, Field MH, Treacy SH, Ruff CG. Physiotherapy at two visits per week for at least 8 weeks is recommended.20 There is little evidence for strapping of meniscal injuries and this is not currently recommended. Weakness, grinding, instability or giving way rarely result from meniscal pathology. Currently, routine MR images do not reveal signal intensity differences between the red and white zones of the menisci. 6 Mri of knee shows "oblique tear posterior horn medial meniscus, lateral patellar plica and minimal synovial knee effusion" will i need surgery? The clinician applies axial pressure to the foot and rotates the tibia internally and externally. Anti-inflammatory drugs such as aspirin, ibuprofen, and naproxen help reduce pain and swelling.

(13a) A coronal image from another patient with a medial meniscal root tear demonstrates associated severe medial subluxation of the meniscal body (arrow). (Left) Radial tear. The most commonly encountered signs are posterior knee pain with deep flexion and joint line tenderness. Because these two tear patterns differ greatly in prognosis and treatment approach, vertical is therefore not the preferred descriptor for such meniscal tears, unless paired with the proper category, such as vertical longitudinal. Results: Medial meniscus posterior horn longitudinal tears in ACL-deficient knees resulted in a significant increase in anterior-posterior tibial translation at all flexion angles except 90 (P < .05). In many areas, nonessential orthopaedic procedures that were postponed due to COVID-19 have resumed. The MRI revealed a vertical flap (oblique) tear of the medial meniscus. Treatment for a meniscus tear will depend on its size, what kind it is, and where it's located within the cartilage.

Principles and decision making in meniscal surgery. 7 Yao L, Stanczak J, Boutin RD. Damaged avascular meniscus must be removed.27 However, meniscectomy causes long term osteoarthritis,28 so is only performed when the patient suffers joint locking or mensical pain that is refractory to conservative management. McMurray test: The patient lies supine on the bed with the hip and knee both flexed. Peripheral meniscal tears are located in the most vascular portion of the menisci and comprise 39-72 % [2, 3, 56, 69, 82] of all meniscal tears. Immediate conservative measures include the RICE regimen: Longer term measures include activity modification, nonsteroidal antiinflammatory drugs (NSAIDs) and physiotherapy.4,1921 Nonsteroidal anti-inflammatory drugs are often recommended for 812 weeks,20 although paracetamol can be considered if NSAIDs are contraindicated or poorly tolerated.22 Where available, intensive physiotherapy is very useful and should include range of motion, proprioceptive work and muscle strengthening exercises. Jarit G, Bosco J. Meniscal repair and reconstruction. Guides you through the decision to have surgery for a torn meniscus. Aged, worn tissue is more prone to tears.

In fact, the tear will most likely get bigger leading to additional damage if not taken care of soon. The Thessaly test is the most sensitive and specific clinical test to diagnose meniscal injury. Absence of the medial meniscus (entire medial meniscal root tear) places large stresses on the ACL, the primary ligament that prevents anterior translation of the knee.

Injury, degeneration, or surgical removal of all or part of the meniscus is associated with an increased risk of developing knee osteoarthritis. Lufkin R. The MRI manual. Knee arthroscopy is one of the most commonly performed surgical procedures. This often signals a tear. History, clinical findings, magnetic resonance imaging, and arthroscopic correlation in meniscal lesions. If the test is positive (suggesting a meniscal tear), the patient will feel pain and the clinician will feel and/or hear meniscal movement when the meniscus is compressed between the tibia and femur 32, Figure 2. Meniscal tears are common sports-related injuries in young athletes and can also present as a degenerative condition in older patients. It presents as a wedge-shaped defect resembling a parrot beak at the free edge of the meniscus as a result of displaced oblique vertical orientation. The lateral meniscus has a symmetrical C-shape, whereas the medial meniscus is more crescentic (3a), as the posterior horn of the medial meniscus is always larger than the anterior horn.

In this case, a portion may break off, leaving frayed edges. Because a torn meniscus is made of cartilage, it won't show up on X-rays. When appropriate, tears that appear to involve the periphery, or red zone of the meniscus, should be described as such (9a), thereby alerting the surgeon to the fact that the tear is more amenable to repair. Disclosures: Blake and Johnson report no relevant financial disclosures.
