Radial meniscal tears historically have been treated by partial meniscectomy, although they are more biomechanically detrimental than longitudinal tears. Clinical results after meniscal repair for radial tears of the midbody of the lateral meniscus have been reported rarely. STUDY
Case series: Level of evidence, 4.
Fourteen consecutive patients who had radial tears of the midbody of the lateral meniscus underwent arthroscopic repair. Inclusion criteria were radial tears involving the red-red or red-white zone. All patients underwent all-inside meniscal repair using absorbable sutures. Postoperative evaluation was performed using joint-line tenderness, McMurray test, range of motion, and follow-up magnetic resonance imaging (MRI) scan at 6 months postoperatively. Lysholm knee score and Tegner activity level were evaluated at last follow-up. In 4 patients, second-look arthroscopies were performed.
The average follow-up was 36.3 months. No patient had joint-line tenderness. Three patients complained of pain or a click on McMurray test. The mean follow-up range of motion was 138.6°. Follow-up MRI scans demonstrated that 5 (35.7%) menisci were healed, 8 (57.1%) were partially healed, and 1 (7.1%) was not healed. The follow-up Lysholm score was 94.7 (range, 81-100; standard deviation [SD] = 6.4) and Tegner score was 5.7 (range, 3-7; SD = 1.4). Second-look arthroscopies in 4 patients showed partial healing of meniscal tears.
Meniscal repair for radial tears of the midbody of the lateral meniscus may be an effective, alternative treatment to partial meniscectomy.

Radial meniscus tears disrupt the circumferential fibers and thereby compromise meniscus integrity. Historically, radial tears were often treated with meniscectomy because of an incomplete understandi...
Meniscus injury and treatment occurred with the majority of anterior cruciate ligament reconstructions (ACLR) in the multicenter orthopaedic outcomes (MOON) cohort. We describe the patient reported ou...
This study was undertaken to diagnose and to document the clinical results and technical aspects of arthroscopic meniscus repair for recurrent subluxation with peripheral tears around the popliteal hi...
Meniscal tears can lead to significant pain and disability, necessitating surgical treatment. Nondisplaced vertical tears are usually smaller in size and can be repaired in most cases; however, bucket...
Meniscectomy remains one of the most frequent orthopedic procedures, despite meniscal sparing having been advocated for several decades now. Incidence is excessive in the light of scientifically robus...
There are two cartilage structures in each knee joint called a meniscus. A torn meniscus can be caused by either a smaller or larger trauma or be a degenerative age-related tear. Arthrosco...
The menisci in the knee joint are important for normal functioning of the knee. Meniscus tears are amongst the commonest of injuries to the knee. The pattern and blood supply of the menisc...
Meniscal repair resulting in meniscal preservation is the most desirable treatment of a torn meniscus and is one of the most commonly performed arthroscopic procedures. The inside-out men...
This is a retrospective study of meniscal tear repairs at least one-year post repair status. All patients were treated with Ceterix NovoStitch devices. The primary objectives of this study...
In the past it was shown, that medial partial meniscectomy (MPM) leads to an increase of the knee adduction moment (KAM) during walking. Other researches found out that an increase of the...
Disease involving the RADIAL NERVE. Clinical features include weakness of elbow extension, elbow flexion, supination of the forearm, wrist and finger extension, and thumb abduction. Sensation may be impaired over regions of the dorsal forearm. Common sites of compression or traumatic injury include the AXILLA and radial groove of the HUMERUS.

A procedure to surgically correct REFRACTIVE ERRORS by cutting radial slits into the CORNEA to change its refractive properties.
The reconstruction of a continuous two-stranded DNA molecule without mismatch from a molecule which contained damaged regions. The major repair mechanisms are excision repair, in which defective regions in one strand are excised and resynthesized using the complementary base pairing information in the intact strand; photoreactivation repair, in which the lethal and mutagenic effects of ultraviolet light are eliminated; and post-replication repair, in which the primary lesions are not repaired, but the gaps in one daughter duplex are filled in by incorporation of portions of the other (undamaged) daughter duplex. Excision repair and post-replication repair are sometimes referred to as "dark repair" because they do not require light.
