Outcomes of an All-Soft Tissue Fixation Technique for Reconstruction of the Medial Patellofemoral Complex Using Double-Bundle Quadriceps Tendon Autograft for Recurrent Patellar Dislocation in Skeletally Immature Patients.

Background: Patellar fracture, femoral physis injury, and recurrent instability are concerning complications in medial patellofemoral ligament (MPFL) reconstruction (MPFLR) techniques for recurrent patellar dislocation in children and adolescents.

Purpose: To evaluate the outcomes of an anatomic all-soft tissue fixation technique for reconstruction of the medial patellofemoral complex (MPFC) using a double-bundle quadriceps tendon (QT) autograft for recurrent patellar dislocation in skeletally immature patients.

Study Design: Case series; Level of evidence, 4.

Double-Bundle Quadriceps Tendon Autograft for Reconstruction of the Medial Patellofemoral Complex to Manage Recurrent Patellar Dislocation in Patients With Open Physes.

Management of chronic patellar instability in patients with open physis requires special reconstruction techniques to minimize the risks of femoral growth plate injury due to the close proximity of the open physis to the native femoral origin of the medial patellofemoral ligament (MPFL). Children and adolescents have a relatively smaller patella than the adult group, so, there is a higher risk of patellar fracture when tunnels are performed in the patella. It is wise to mimic the normal anatomy of the medial patellofemoral complex (MPFC) by reconstruction of both of the medial quadriceps tendon femoral ligament (MQTFL) and MPFL, so as to restore the normal fan-shaped MPFC, with its wide anterior attachment to both of the patella and quadriceps tendon (QT).

Biological Bone Plate and Iliac Bone Autograft for Proximal Tibial Slope Changing Osteotomy in Genu Recurvatum.

Genu recurvatum (GR) is defined as knee hyperextension greater than 5°, with the normal physiological accepted limits of up to 10 to 15° of extension. Physiological GR is commonly bilateral, symmetrical, and mostly asymptomatic. Pathologic GR is usually asymmetric, symptomatic, and can be congenital or acquired.

Arthroscopic Single-Tunnel Pullout Suture Fixation for Tibial Eminence Avulsion Fracture.

Various arthroscopic techniques have been devised for fixation of tibial eminence avulsions, namely percutaneous K-wires, arthroscopy-guided screw fixation, staples, TightRope (Arthrex)-suture button fixation, and transosseous suture fixation. Such techniques provide well-pronounced advantages including less postoperative pain, a reduced hospital stay, and minimal scar with resultant earlier and more compliant rehabilitation. As for transosseous suture fixation, the standard technique comprises the creation of 2 tibial tunnels exiting on both sides of the footprint of the avulsion fracture using an anterior cruciate ligament tibial guide with the angle set at 45°.

Autogenous Hamstring-Bone Graft Preparation for Anterior Cruciate Ligament Reconstruction.

Despite the popularity of anterior cruciate ligament (ACL) reconstruction procedures, the ideal graft for reconstruction remains a matter of controversy. The ideal graft for ACL reconstruction should have histologic and biomechanical characteristics similar to those of the native ACL; should be quickly and fully incorporated within the bony tunnels; should maintain its viscoelastic properties for a long time; should have minimal donor-site morbidity; should be of sufficient length and diameter; should have minimal adverse effects on the extensor mechanism; should have no risk of rejection or disease transmission; and should be cost-effective and readily available. Synthetic grafts are not widely accepted because of their dangerous complications.

Combined Anatomic Anterior Cruciate Ligament and Double Bundle Anterolateral Ligament Reconstruction.

The results of arthroscopic anterior cruciate ligament (ACL) reconstruction are so far satisfactory and improving over time as a result of the improved understanding of the anatomy and biomechanics of the ACL. Rotational instability confirmed by a positive pivot shift is present in more than 15% of cases who underwent successful ACL reconstruction. Persistent rotational instability interferes with performing pivoting sports, and also may lead to meniscal and chondral injuries, or re-rupture of the reconstructed ACL.

Combined Anatomic Reconstruction of the Anterior Cruciate and Anterolateral Ligaments Using Hamstring Graft Through a Single Femoral Tunnel and With a Single Femoral Fixation.

Patients with complete anterior cruciate ligament (ACL) injury have different degrees of rotational (internal rotation) laxity. A residual pivot shift has been found to be positive in more than 15% of cases after an accurate ACL reconstruction. Improved understanding of the existence, function, and biomechanical role of the anterolateral ligament (ALL) in controlling rotational instability of the knee has redirected and refocused attention on a supplemental extra-articular reconstruction of the ALL in conjunction with the intra-articular ACL reconstruction so as to restore normal kinematics of the knee.

Step-by-Step Arthroscopic Assessment of the Anterolateral Ligament of the Knee Using Anatomic Landmarks.

New insights into the existence and function of the anterolateral ligament (ALL) of the knee have redirected and refocused attention on the secondary restraints of rotational stability of the knee. The importance of assessing the ALL is increasing, especially in anterior cruciate ligament reconstruction surgery, to decide on the need for an adjunctive extra-articular reconstruction of the ALL to control rotational instability of the knee. However, preoperative assessment of this ligament is difficult.
