Sartorial branch of the saphenous nerve in relation to a medial knee ligament repair or reconstruction.
Surgical approaches to repair or reconstruct the medial knee structures note caution to avoid the sartorial branch of saphenous nerve. However, the approximate area of potential iatrogenic nerve injury has not been previously described in relation to landmarks for a medial knee reconstruction. The purpose of this study was to define the course of the sartorial branch of the saphenous nerve in relation to the superficial medial collateral ligament. ⋯ The distance from the anterior border of the superficial medial collateral ligament to the sartorial branch of the saphenous nerve decreased as the distance was increased distally with a mean distance of 4 cm (4.1 +/- 0.8 cm) distal from the joint line and 6 cm (3.8 +/- 0.8 cm) distal from the joint line. We have characterized the surgically relevant landmark anatomy of the sartorial branch of the saphenous nerve in regards to performing a repair or reconstruction of the medial knee structures. Familiarity with these anatomic landmarks and associated distances from the sartorial branch of the saphenous nerve, we can assess the potential area of vulnerability to this nerve branch intraoperatively.

Randomized Controlled Trial Multicenter StudyAutologous patellar tendon and quadrupled hamstring grafts in anterior cruciate ligament reconstruction: a prospective randomized multicenter review of different fixation methods.
ACL reconstruction with bone patellar tendon bone (BPTB) grafts has been shown to produce dependable results. Recently, reconstructions with double-looped semitendinosus gracilis (DLSG) grafts have become common. The prevailing opinion is that ACL reconstruction with patellar tendon graft produces a more stable knee with more anterior knee pain than DLSG grafts, while the functional results and knee scores are similar. ⋯ BPTB ACL reconstruction fixed with interference screws and DLSG fixed with Bone Mulch Screws on the femur and WasherLoc Screws on the tibia produce satisfactory and nearly identical outcomes. Among our patients in the DLSG group, flexion strength was lower, and more patients underwent meniscus surgery in the follow-up period. The BPTB group has more anterior knee pain.

Are evidence-based protocols which identify vascular injury associated with knee dislocation underutilized?
A concerning number of patients referred to our clinic with knee dislocations have not been thoroughly evaluated for popliteal injury. The objective of this study is to present our experience and attempt to identify possible causes for this trend. Thirty-one consecutive patients with knee dislocations referred over a 1-year period were evaluated. ⋯ The consequences of a delay in diagnosis beyond 8 h can be catastrophic and one patient in this series required an above-knee amputation. This is not new information, however, a significant number of patients with knee dislocations continue to be evaluated solely by initial pedal pulse examination. Though effective protocols exist, orthopedic surgeons must work to facilitate the implementation of these protocols at their referring institutions.
