What is a cleavage tear?

Such a tear is the functional equivalent of a total meniscectomy. Radial tear. Horizontal cleavage tears usually occur in older individuals. They extend from the inner free margin peripherally to the intrameniscal substance where myxoid degeneration may be present.

Correspondingly, what is a meniscal cyst?

The meniscus is a cartilage pad that serves as a shock absorber, provides stress transmission, enhances lubrication and facilitates nutrition to the knee. When the meniscus is torn, a small cyst can form adjacent to the tear. This cyst is thought to develop as part of the body’s healing response.

What causes a Baker’s cyst behind the knee?

Baker’s cysts are not uncommon and can be caused by virtually any cause of joint swelling (arthritis). The excess joint fluid (synovial fluid) bulges to the back of the knee to form the Baker’s cyst.

What is a tear of the medial meniscus?

The menisci — the medial meniscus and lateral meniscus – are crescent-shaped bands of thick, rubbery cartilage attached to the shinbone (tibia). They act as shock absorbers and stabilize the knee. The medial meniscus is on the inner side of the knee joint. The lateral meniscus is on the outside of the knee.

What is the posterior horn of medial meniscus?

Description of Posterior Horn Medial Meniscus Tear. It varies from the main weightbearing portion of the meniscus up to where it attaches on the tibia at its lateral aspect, called the root attachment. The posterior horn of the medial meniscus is the most important weightbearing portion of the meniscus.

What is a tear of the posterior horn of the medial meniscus?

People can suffer tears of the meniscus because of trauma, sports injuries or the meniscus can tear simply because it wore out. By far, the most common location for a tear is in the back, and on the inner or medial side of the knee — that is the area we call the posterior horn of the medial meniscus.

What is a radial tear?

There are radial tears, which are short tears that extend from the inner margin of the meniscus and head towards the periphery or outer part of the meniscus. There is a picture above of a radial tear. There are also horizontal cleavage tears.

What is a cystic meniscus?

The meniscus is a cartilage pad that serves as a shock absorber, provides stress transmission, enhances lubrication and facilitates nutrition to the knee. When the meniscus is torn, a small cyst can form adjacent to the tear. This cyst is thought to develop as part of the body’s healing response.

What is a Intrasubstance tear?

Interstitial tears (Figure 6), also known as intrasubstance tears or intramuscular cysts, can occur in isolation within the tendon without articular- or bursal-sided extension, or they can also occur in combination with either articular- or bursal-sided partial thickness tears.

What is a mucoid degeneration?

Mucoid degeneration (MD) is a rare pathological affection of the anterior cruciate ligament (ACL). Mucinous material within the substance of ACL produces pain and limited motion in the knee.

What is the meaning of mucoid degeneration?

medical Definition of mucoid degeneration. : tissue degeneration marked by conversion of cell substance into a glutinous substance like mucus.

What is cystic degeneration of the ACL?

The lesion may manifest as an elongated cyst along the long axis of the ACL, or as an enlarged ACL. This appearance can mimic acute or chronic interstitial partial tears of the ligament [1]. Long with tears and ACL ganglion cysts, mucoid degeneration is a relatively common cause of increased signal within the ACL [1].

What is a myxoid degeneration?

A degenerative process in which the connective tissues are replaced by a gelatinous or mucoid substance. Supplement. For instance, myxoid degeneration of the tendon occurs when the normal fibrilary appearance of the tendon is replaced by a homogenous, opaque, mucoid type of tissue.

What is the ICD 10 code for ACL tear?

Sprain of anterior cruciate ligament of left knee, initial encounter. S83.512A is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2018 edition of ICD-10-CM S83.512A became effective on October 1, 2017.

What is an internal derangement of the knee?

Internal derangement of the knee (IDK), for the purposes of VAC , is a chronic disorder of the knee due to a torn, ruptured or deranged meniscus of the knee, or a partial or complete cruciate rupture, with or without injury to the capsular ligament of the knee, resulting in ongoing or intermittent signs and symptoms

What is CPT code 29888?

The CPT code for an arthroscopic ACL reconstruction is 29888, “Arthroscopically aided anterior cruciate ligament repair/augmentation or reconstruction.”

What is CPT code 29889?

CPT 29889, Under Endoscopy/Arthroscopy Procedures on the Musculoskeletal System. The Current Procedural Terminology (CPT) code 29889 as maintained by American Medical Association, is a medical procedural code under the range – Endoscopy/Arthroscopy Procedures on the Musculoskeletal System.

What is CPT code 29880?

HCPCS code G0289 may be reported in addition to CPT® code 29880, Arthroscopy, knee, surgical; with meniscectomy (media AND lateral, including any meniscal shaving) or CPT® code 29881, Arthroscopy, knee, surgical; with meniscectomy (medial or lateral, including any meniscal shaving)if performed in a separate compartment

What is procedure code 29875?

ASC Coding Guidance: Arthroscopic Knee Synovectomy Reporting. The lateral synovectomy, CPT 29875, is inclusive in the lateral meniscectomy procedure reported with CPT 29881. Only the medial compartment will have a final synovectomy reporting of CPT 29875.

What is the CPT code 29879?

One of the biggest challenges in coding knees occurs with the determination of reporting CPT 29877, arthroscopy knee, surgical; debridement/shaving of articular cartilage (chondroplasty) vs. CPT 29879, arthroscopy knee, surgical; abrasion arthroplasty (includes chondroplasty where necessary) or multiple drilling or

What is a cyclops lesion?

The cyclops lesion, also known as localised anterior arthrofibrosis, is a painful anterior knee mass that arises as a complication of anterior cruciate ligament (ACL) reconstruction, although has rarely been reported in patients with ACL injuries that have not been reconstructed.

What is a meniscectomy of the knee?

Arthroscopic meniscectomy is an outpatient minimally invasive surgical procedure used to treat a torn meniscus cartilage in the knee. The meniscus is often torn as a result of sport-related injury in athletic individuals. Only the torn segment of the meniscus is removed.
