New meniscus repair by an all-inside knot suture technique.

The indications for the all-inside knot suture technique include tears in the red-red zone or red-white zone in the meniscus, and a horizontal tear, a vertical tear, and a peripheral tear. First, find an appropriate place for a suture insertion site with a Kateran needle or a spinal needle. Make sure it exits beyond the tear in the meniscus. Once the insertion site is chosen, a suture is passed into and through the joint. The suture is slowly pulled back. You should be able to feel the tip of the suture come out of the joint capsule. If you want to make a vertical suture to suture the tear, move the suture vertically apex. Then insert the suture back into the joint through the capsule. Make sure the suture stays inside the joint. Find and grab the suture with a punch inserted from the clear cannula. Pull the suture out of the joint through the clear cannula with the punch. Tighten the knot with a knot pusher. Then confirm the stability of the sutured site with the probe. Our all-inside knot suture technique can be performed arthroscopically, allowing reliable repair of the torn meniscus.

Discoid lateral menisci in Japanese cadaver knees.

We undertook a descriptive, observational study to determine the prevalence of the discoid lateral menisci. The relation between the lateral meniscal shapes and the incidence of meniscal tears were studied, and the gender differences in discoid lateral menisci and the similarities of the lateral meniscal shapes in bilateral knees were examined. A total of 602 knees from 306 cadavers were macroscopically analyzed. Altogether, 577 lateral menisci were classified into the following three types: normal type (NM); incomplete discoid type (ICDM); and complete discoid type (CDM). Each lateral meniscus was examined for meniscal tears. The prevalence of a discoid lateral meniscus and gender differences in its prevalence were examined, as were the presence of a meniscal tear for the three types of lateral meniscus. In all, there were 21 (3. 6%) CDM cases and 171 ICDM cases (29.6%). The prevalence of discoid lateral meniscus, including ICDM and CDM, in the female cadavers was significantly higher than that in the male cadavers, but there was no significant gender difference in the prevalence of CDM. It was found that the shape of the lateral meniscus was similar bilaterally. The incidence of meniscal tears for ICDM was significantly higher than that for NM.

Patellar dislocation: arthroscopic patellar stabilization with anchor sutures.

There are many procedures to treat recurrent patellar subluxations and dislocations. Most of these procedures are open repairs for acute conditions or open reconstructions for chronic conditions, and both surgeries need large skin incisions. Although there are many arthroscopic procedures for meniscal and ligament injuries, there are very few arthroscopic procedures described for patellofemoral instability. In this report, we describe a new arthroscopic method to stabilize the patella for acute dislocation. Our technique includes an arthroscopic lateral release and a medial structure repair. We suggest that this procedure is minimally invasive and easier than traditional open procedures. Moreover, this may prevent patients from developing chronic instability of the patellofemoral joint.
