Arthroscopic Treatment of Tibial Eminence Avulsion Fracture With Suture Tensioning Technique.

Although a tibial eminence avulsion fracture is a rare knee injury, it can result in some complications such as nonunion, limited range of motion, and anterior instability of the knee if the displaced fracture is not well reduced. Arthroscopic procedures for this fracture have been commonly performed in recent years. In patients with small fragments, a pullout operation is usually performed, but arthroscopic suture reduction is technically difficult.

Surgical Technique to Bring Down the Patellar Height and to Reconstruct the Tendon for Chronic Patellar Tendon Rupture.

Although surgical treatment is the gold standard for chronic patellar tendon rupture, the technique of patellar tendon reconstruction is still difficult. Basically, good clinical results of surgical repair for acute patellar tendon rupture have been reported. However, the results of reconstructive surgery for chronic patellar tendon rupture are still inconsistent.

Self-flip Technique of the TightRope RT Button for Soft-Tissue Anterior Cruciate Ligament Reconstruction.

The TightRope RT (Arthrex, Naples, FL) is a suspensory device for anterior cruciate ligament reconstruction. However, there is a potential risk of the button being pulled too far off the lateral femoral cortex into the soft tissue because the adjustable loop is long. The purpose of this article is to present an easy and safe technique for self-flip.

Three-dimensional knee kinematics in patients with a discoid lateral meniscus during gait.

Background: To date, the knee kinematics of a discoid lateral meniscus (DLM) has not been elucidated. The aim was to investigate the three-dimensional knee kinematics in knees with a DLM using gait analysis.

Methods: Ten patients (mean: 14years) diagnosed with bilateral DLM and unilaterally symptomatic snapping as well as 10 healthy controls (mean: 23years) participated in the study.

Arthroscopic Visualization of Abnormal Movement of Discoid Lateral Meniscus With Snapping Phenomenon.

Discoid lateral meniscus with snapping phenomenon is a rare pathologic condition. The purpose of this article is to present an arthroscopic technique for the treatment of discoid lateral meniscus with snapping phenomenon. The patient is placed in the supine position for confirmation of snapping.

Effect of unstable meniscal injury on three-dimensional knee kinematics during gait in anterior cruciate ligament-deficient patients.

Background: Our purpose was to clarify the differences of three-dimensional knee kinematics in anterior cruciate ligament (ACL)-deficient patients between with and without meniscal injury using gait analysis.

Methods: A total of 72 knees in 36 young athletes with primary and unilateral ACL injury, with a mean age of 22 years, participated. Gait analysis was done before surgery.

A Novel Surgical Technique for Patellar Fracture: Application of Extra-articular Arthroscopy With Hanger-Lifting Procedure.

We describe a novel operative technique for patellar fracture. The patient is placed in the supine position for setup of both an image intensifier and arthroscopy. After routine intra-articular inspection with an arthroscope, an extra-articular space including the prepatellar bursa is developed.

The "coiling-up procedure": a novel technique for extra-articular arthroscopy.

The "coiling-up procedure" is a novel technique for extra-articular arthroscopy. A coil-shaped lifter is used to create the extra-articular working space, and a dry arthroscopy is performed. It can be combined with conventional intra-articular arthroscopy to enable direct vision from both inside and outside the joint.

Medial patellofemoral ligament reconstruction with hanger lifting procedure.

Medial patellofemoral ligament (MPFL) reconstruction has become a common surgical procedure in the treatment of recurrent dislocation of the patella. A technique of MPFL reconstruction with the "hanger lifting procedure" using extra-articular arthroscopy is presented. After conventional intra-articular arthroscopy, an incision about 1 cm long is made at the superomedial edge of the patella.

Hanger-lifting procedure in knee arthroscopy.

We propose a unique arthroscopic technique, the "hanger-lifting procedure." Unlike conventional arthroscopy, the space in which the arthroscope is placed is not a joint space filled with water but a subcutaneous space filled with air. The space is kept lifted by a semi-loop-shaped hanger and a retraction system by use of a wire.
