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(More)
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.(More)
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.(More)
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(More)
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.(More)
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. Level of evidence IV.
