The objective of this study was to arthroscopically analyse the morphology and dynamics of variants of the anterior horn of the medial meniscus of the knee (VAMM) and to then consider the pathological significance of these variants. VAMM was defined as knees in which the anterior horn of the medial meniscus is not attached to the tibia. Between April 1992 and March 1995, arthroscopy was performed on 953 knees of 903 patients. ⋯ In these cases, even detailed arthroscopic observation proved the causes of the symptoms or injury. On the basis of these findings, we surmised that the anterior portion shows hypermobility at the time of flexion/extension of the knee, regardless of the type of VAMM. In this study, we discussed the possibility that the existence of VAMM may become the cause of pain or injury to the meniscus.

Comparative Study
The efficacy of regional anesthesia for outpatient anterior cruciate ligament reconstruction.
Arthroscopically assisted anterior cruciate ligament (ACL) reconstruction is a common orthopaedic procedure. Until recently, the majority of these procedures have been performed on an impatient basis. This retrospective study evaluated 67 consecutive patients who underwent an arthroscopically assisted, autogenous bone-patellar ligament-bone ACL reconstruction that was supervised by the same surgeon. ⋯ The use of this technique was not found to compromise operating room efficiency. Patients receiving regional anesthesia did require a slightly longer recovery room stay. ACL reconstruction performed under regional anesthesia with same-day discharge was well tolerated by our patients and it provides a cost-efficient alternative to ACL reconstructions performed as inpatient procedures.

Case Reports
Arthroscopic reduction and fixation of bony avulsion of the posterior cruciate ligament of the tibia.
Bony avulsion fractures of the posterior cruciate ligament of the tibia have commonly been treated by open reduction and internal fixation using the posterior approach. However, this approach, using the prone position, makes it difficult to investigate and treat other combined injuries of the knee joint. ⋯ The posterior sag was absent after the operation and the result was excellent. By arthroscopy, we got rigid fixation of the avulsed fragment for early rehabilitation, and detection of a concomitant injury was also possible.
