The Ahlbäck system has been found to have comparable interobserver precision and arthroscopy correlation to the IKDC system, but most of the span of the Ahlbäck system focused at various degrees of bone defect or loss, and it is therefore less useful in early osteoarthritis. It was formed by a group of knee surgeons from Europe and America who met in 1987 to develop a standard form to measure results of knee ligament reconstructions. severe joint space narrowing, or joint space obliterationįor the grading of osteoarthritis in the knee, the International Knee Documentation Committee (IKDC) system is regarded to have the most favorable combination of interobserver precision and correlation to knee arthroscopy findings.minor joint space narrowing (normal joint space is at least 2 mm at the superior acetabulum).Severe (Tönnis grade 3) osteoarthritis of the hip. There is no consensus whether it is more or less reliable than the Kellgren-Lawrence system. Osteoarthritis of the hip joint may also be graded by Tönnis classification. Large osteophytes, marked joint space narrowing, severe sclerosis and definite bony deformity Multiple osteophytes, definite joint space narrowing, sclerosis and possible bony deformity Possible joint space narrowing (normal joint space is at least 2 mm at the superior acetabulum) and osteophyte formationĭefinite osteophyte formation with possible joint space narrowing No radiographic features of osteoarthritis The most commonly used radiographic classification system for osteoarthritis of the hip joint is the Kellgren–Lawrence system (or KL system). Hip Hip joint with no signs of osteoarthritis. Samilson–Prieto classification GradeĮxostosis of inferior humerus and/or glenoid measuring less than 3 mmĮxostosis of inferior humerus and/or glenoid measuring 3–7 mm, and slight irregularity of the jointĮxostosis of inferior humerus and/or glenoid measuring more than 7 mm in height as well as sclerosis and narrowing of the joint space (normal joint space is 4–5 mm). The Samilson–Prieto classification is preferable for osteoarthritis of the glenohumeral joint. Small chondrophytes or osteophytes at marginsįibrocartilage extending from subchondral bone irregularity and focal sclerosis in subchondral boneĬlefts extended through nucleus and annulus Thomson grading of lumbar disc degeneration GradeĮxtensive mucinous infiltration loss of annular-nuclear demarcation The Thomson grading system is regarded to have more academic than clinical value. Lane grading of lumbar disc degeneration Grade Kellgren grading of cervical disc degeneration I Weishaupt grading of lumbar facet joint degeneration (by MRI and computed tomography).Pathria grading of lumbar facet joint degeneration (by computed tomography).Thompson grading of lumbar disc degeneration (by magnetic resonance imaging).Lane grading of lumbar disc degeneration.Kellgren grading of cervical facet joint degeneration.Kellgren grading of cervical disc degeneration.There are many grading systems for degeneration of intervertebral discs and facet joints in the cervical and lumbar vertebrae, of which the following radiographic systems can be recommended in terms of interobserver reliability: ![]() In osteoarthritis, the choice of treatment is based on pain and decreased function, but radiography can be useful before surgery in order to prepare for the procedure. Radiographic systems to classify osteoarthritis vary by which joint is being investigated. Radiographic classification of osteoarthritis ![]()
