In cases with root tear of the medial meniscus posterior horn, the meniscus usually can be repaired by a pull out suture technique. However, there is difficulty in manipulating a suture hook via the anteromedial portal and looking through the arthroscopic camera via anterolateral portal in the narrow medial joint space at the same time. This article describes a modified simple pull out suture t...

We have investigated the effectiveness and safety of a newly developed biological adhesive for repair of meniscal tear. The adhesive was composed of disuccinimidyl tartrate (DST) as a crosslinker and human serum albumin (HSA) as a hardener. To determine adequate concentration, bonding strength was measured using a tensiometer 5 min after applying the adhesive on the avascular zone tear of porci...

PURPOSE To elucidate the effect of the cotton thread test (CT-T) and Schirmer test (S-T) on the tear reservoir by evaluating the radius of tear meniscus curvature. METHODS The radii (R) of the central lower tear menisci were measured by a newly developed video meniscometer in 11 eyes of 11 normal volunteers (6 men, 5 women; mean age, 27.7 +/- 3.6 years [SD]) and 9 eyes of 9 patients with tear...

The meniscus plays an important role in the function of the knee. Preservation of the meniscus is preferred if possible when considering treatment of a meniscus tear. A thorough understanding of the anatomy of the meniscus, the structure, the mechanics, and other factors of meniscal healing are critical when evaluating the torn meniscus for a reparative procedure. Many options for meniscus repa...

Background: Meniscus tissue is highly susceptible to injury and tears. As these are intrasynovial and lack cellularity, their healing potential is less. Any knowledge to the factors affecting the meniscal healing can help surgeons in treating meniscal injuries. Hypothesis: Patient age is a predictor of the healing of meniscus tissue. Study Design: Prospective study. Methods: Gross and histologi...

The anatomy of 1000 symptomatic meniscus lesions is described and related to the age of the patients. All symptomatic lesions found during the study period were treated by arthroscopic surgery. Meniscal lesions were commoner in the right knee (56.5%) and 81% of the patients were men. Of the medial meniscus tears, 75% were vertical and 23% horizontal. Vertical tears of the medial meniscus occurr...

BACKGROUND Tears of the posterior root of the medial meniscus are becoming increasingly recognized. They can cause rapidly progressive arthritis, yet their biomechanical effects are not understood. The goal of this study was to determine the effects of posterior root tears of the medial meniscus and their repairs on tibiofemoral joint contact pressure and kinematics. METHODS Nine fresh-frozen...

BACKGROUND Radial transection of the peripheral fibers of the meniscus could render it nonfunctional; however, the biomechanical consequences of a complete lateral meniscal radial tear and repair in human specimens have not been elucidated. HYPOTHESIS A complete radial tear will exhibit knee contact mechanics approaching those of total meniscectomy. Repair of complete radial tears will re-cre...

Discoid meniscus is an anatomical congenital anomaly more often found in the lateral meniscus. A discoid medial meniscus is a very rare anomaly, and even more rare is to diagnose a bilateral discoid medial meniscus although the real prevalence of this situation is unknown because not all the discoid medial menisci are symptomatic and if the contralateral knee is not symptomatic then it is not u...

Menthol is thought to stimulate lacrimation via activation of cold-sensitive primary afferent neurons in the cornea. We evaluated a warm compress containing menthol as a potential treatment for dry eye by examining its effects on the tear film in healthy subjects (n = 20) and dry eye patients (n = 35). Disposable eyelid-warming steamers that either did (MH) or did not (HO) contain menthol were ...
