Posterior Horn Repair Augmented With the Central Portion of Thickened Meniscus for Large Posterolateral Corner Loss Type of Discoid Lateral Meniscus.

Large posterolateral corner loss type of discoid lateral meniscus tear is unsalvageable. Therefore, subtotal meniscectomy has been the only treatment option in this case. However, long-term results of subtotal or total meniscectomy have shown a high prevalence of early degenerative changes.

Channel Measurement and Feasibility Test for Wireless Avionics Intra-Communications.

Wireless avionics intra-communication (WAIC) refers to a wireless communication system among electronic components (e.g., sensors and actuators) that are integrated or installed in an aircraft and it is proposed to replace heavy and expensive wired communication cables.

Lateral meniscus allograft transplantation: an arthroscopically-assisted single-incision technique using all-inside sutures with a suture hook.

We present an arthroscopically-assisted single-incision technique using all-inside sutures with a suture hook in the lateral meniscus allograft transplantation. Although this technique is technically demanding, it provides vertically oriented and secure sutures with good tissue approximation without the accessory skin incision.

The safe establishment of a transseptal portal in the posterior knee.

Purpose: The aims of this study were as follows: (1) to determine the dimensions of the posterior compartments and the location of the popliteal artery with regard to the posterior septum by magnetic resonance arthrography; (2) to assess the effect of demographic factors on the measurements taken; and (3) to find a safe means of establishing the transseptal portal.

Methods: Thirty magnetic resonance arthrographies taken in 90° of flexion were evaluated to simulate knee position during arthroscopic surgery. Coronal and axial images were obtained in positions parallel and perpendicular to the long axis of the tibia, respectively.

Is correctional osteotomy crucial in primary varus knees undergoing anterior cruciate ligament reconstruction?

Background: Valgus high tibial osteotomy (HTO) has been recommended for ligament stability and enhanced function after anterior cruciate ligament (ACL) reconstruction in varus-angulated knees. However, it is not clear whether HTO should be performed in patients undergoing ACL reconstruction who have primary varus knees without medial compartment arthrosis.

Questions/purposes: We therefore asked whether stability and function differed in patients having ACL reconstruction with differing degrees of preoperative alignment.

A biomechanical comparison of 3 reconstruction techniques for posterolateral instability of the knee in a cadaveric model.

Purpose: The objective of this study was to compare the varus and external rotatory laxity of reconstructed knees by use of 3 different reconstruction techniques that address posterolateral instability of the knee: popliteus tendon (PT) and lateral collateral ligament (LCL) reconstruction, PT and popliteofibular ligament (PFL) reconstruction, and PFL and LCL reconstruction.

Methods: We divided 36 fresh-frozen cadaveric knees into 3 groups of 12, and each group was assigned to a reconstruction technique: PT-LCL reconstruction with the posterior tibialis tendon, PT-PFL reconstruction with the patellar tendon and bone (Warren technique), and PFL-LCL reconstruction with the semitendinosus tendon (Larson technique). Each specimen was fixed with an Ilizarov external fixator and mounted on a custom-designed apparatus that was made to measure posterolateral instability of the knee, that is, external rotatory and varus laxity in the intact state, after cutting, and in the postoperative state at every 30 degrees from 0 degrees to 90 degrees .

A combined transglenoid and suture anchor technique for bony Bankart lesions.

We present a modified hybrid technique that is a combination of a transglenoid and suture anchor technique. Three-dimensional CT reconstruction is indicated for patients with bony fragments larger than 10 mm. First, a transglenoid technique is performed to reduce the bony fragment and then a suture anchor technique is performed to achieve a stable fixation.

Is the transglenoid suture technique recommendable for recurrent shoulder dislocation? A minimum 5-year follow-up in 59 non-athletic shoulders.

The aim of this retrospective study is to compare the clinical outcomes following arthroscopic Bankart repair employing the transglenoid technique versus suture anchors in non-athletic shoulders of patients 30 years or older at the time of surgery. Fifty-nine consecutive patients who were available for a minimum of 5 years follow-up after arthroscopic Bankart repair were included. The transglenoid technique was employed in 27 patients whose age and follow-up period were 37 years (range 30-58) and 82 (range 61-109) months.
