This type of tear is particularly devastating to meniscal function. Incisions were made in the dorsal root of the oblique popliteal ligament and the joint capsule . These lie on the inside (medial) and outside (lateral) edges of the top of your tibia (shin bone). There is a history of sudden inability to fully extend the knee, with a rotational flexion/extension 'trick' required to regain full extension. Arthroscopic repair An arthroscope is inserted into the knee to see the tear. Sometimes these tears require surgical repair. Another exam finding is palpating the anteromedial joint line, while placing a varus stress on a fully extended knee and feeling for meniscal extrusion.

Proton weighted sagittal image demonstrates an example of a posterior horn medial meniscal horizontal tear (white arrow). The meniscus root attachment aids meniscal function by securing the meniscus in place and allowing for optimal shock-absorbi (6a) A radial tear of the body of the lateral meniscus also appears vertical on sagittal MR images (arrow), though in the case of radial tears, the lesion is oriented perpendicular to the c-shaped fibers of the meniscus. The medial meniscus is on the inner side of the knee joint. A tear in this "red" zone may heal on its own, or can often be repaired with surgery. History, clinical findings, magnetic resonance imaging, and arthroscopic correlation in meniscal lesions. This tear pattern was historically unrecognized, although more recently it has been suggested this hidden pathology may account for nearly 80% of the total knee replacements in patients younger than 60 years. A magnetic resonance imaging (MRI) scan is often used to diagnose meniscal injuries. Pain is typically medial and activity-related (e.g. The outer one-third of the meniscus has a rich blood supply. Perhaps the best know of these is the bucket-handle tear. Nonoperative treatments are often successful in patients with certain types of tear patients who have no loss of joint function, suffer minimal pain or swelling and are willing to reduce their activities temporarily or in the long term. The procedure can reduce pain, improve mobility and stability, and get you back to life's activities. Makris EA, Hadidi P, Athanasiou KA. RICE stands for Rest, Ice, Compression, and Elevation.

When people talk about torn cartilage in the knee, they are usually referring to a torn meniscus. The skilled interpreter of MR of the knee must do more than simply identify the presence of a meniscal tear. With regard to tear morphology, the classic ideal candidate for meniscal repair is the peripheral longitudinal tear. The absolute indication for specialist referral is the locked knee loss of joint function necessitates surgical intervention. A high level of suspicion is required to detect these injuries, and repair is recommended to preserve joint function. Clin J Sport Med 2009;19:912. Of note, drilling tibial tunnels may improve healing of the meniscus-bone interface due to the presence of progenitor cells and growth factors derived from the bone marrow. Meniscal intra-substance signal abnormalities are defined as an increased signal that does not fulfill the criteria for a meniscal tear according the "two-slice-touch" rule (i.e., it does not reach the meniscal surface on two consecutive views) and is a common finding on routine MRI of the knee (Fig. controlling the movements of the knee joint. A gradient-echo T2*-weighted sagittal image demonstrates a tear within the posterior horn of the medial meniscus (arrow). These injuries have been reported to change joint loading due to failure of the meniscus to convert axial loads into hoop stresses. Meniscal tears are categorised as traumatic or non-traumatic (degenerative) on the basis . When displacement is not evident on MR images, additional criteria that suggest tear instability include the presence of fluid signal intensity within the tear on T2-weighted images, a tear that is greater than 10mm in length, and tears with complex patterns (10a). X-rays and MRIsallow the doctor to evaluate the bone and soft tissue at the knee. Call us today at (410) 644-1880 or (855) 4MD-BONE (463-2663) to schedule an appointment. A meniscectomy requires less time for healing approximately 3 to 6 weeks. This tear is usually best seen on the coronal T2-weighted MRI scan (see figure 1), where a fragment of meniscus (black in appearance) is stuck between the medial tibial plateau and the overlying medial collateral ligament.This tear pattern tends to be persistently painful, as the meniscal fragment becomes entrapped between bone and the adjacent soft tissues. Conservative management of the patient with a meniscal tear. 17 Old Kings Road N., Suite K Palm Coast, FL 32137, East Coast Surgery Center (10a) A GRE T2*-weighted sagittal image reveals a complex tear of the posterior horn of the medial meniscus, having horizontal (arrows) and longitudinal (arrowhead) components.

This means that athletes, especially those who participate in contact sports like football, are at a higher risk of sustaining this injury. Sports-related meniscus injuries often occur along with other knee injuries, such as anterior cruciate ligament (ACL) tears. Principles and decision making in meniscal surgery. Tears should be characterized with regard to morphology, size, location, and stability, all of which are important factors that may influence the choice of operative treatment.

(12a) A radial tear (arrow) truncates the central attachment/root of the posterior horn of the medial meniscus on this fat suppressed proton density-weighted coronal image. The procedure begins with a complete diagnostic arthroscopy using a 30-degree arthroscope. It is important that these root avulsions are anatomically repaired back to the bone. Helms CA, Laorr A, Cannon WD, Jr. The menisci of the knee have several important roles: The medial meniscus is 'C' shaped whereas the lateral is a shorter incomplete circle with closer spaced 'horns'.

It absorbs about 50% of the shock of the medial compartment. Other nonsurgical treatment. The anatomic landmark for repair is anterior to the PCL footprint on the tibia. This part of the tibia is also known as the tibial plateau. Tears that are stable, < 1 cm in length, and that do not cause significant . Adjunctive measures to promote vascularity and healing at the repair sites are also recommended. In younger patients, this is typically a twisting force on a weightloaded flexed knee. The tear can be seen as a white line through the dark body of the meniscus. Semin Roentgenol. Symptoms. Two months later, the post-operative image (17b) reveals a repaired, normal appearing lateral meniscal body (arrow), with resolution of the previously seen displaced fragment.

Age of injury peaks at 2029 years.7 Partial meniscectomy (removal of the torn section) is one of the most commonly performed orthopaedic surgical procedures.8. 2nd edn. The healing time in children is a little less as the healing process is faster in children than in adults. These tears often occur in association with ACL tears, but even if found in isolation, are highly likely to be clinically relevant, as the displaced meniscal fragment frequently results in knee locking. Surgical treatment is usually reserved for younger patients with a vertical longitudinal tear within the vascularised outer third of the meniscus. X-rays provide images of dense structures, such as bone. The operative equipment needs and post-operative rehabilitation process markedly differ between meniscal repair and partial meniscectomy.
