Cortical Button Fixation for Proximal Tibiofibular Instability: A Technical Report
Instability of the proximal tibiofibular joint (PTFJ) is a rare injury pattern than can affect high-demand athletes involved in twisting or pivoting movements on a flexed knee. Instability may produce painful subluxations during provocative activity and occasional neuritic symptoms from tethering of the common peroneal nerve at the fibular neck. There are several reports of reconstruction for symptomatic PTFJ instability; however, no optimal treatment has been elucidated in the literature. Use of a cortical button suspensory device for fixation of the PTFJ offers the advantage of stabilizing the joint without need for free graft harvest or rigid screw fixation. The present technical report illustrates the operative technique and the advantages, disadvantages, pearls, and pitfalls associated with this operation
A Staged Arthroscopic Approach to Fixation of Unstable Osteochondritis Dissecans in the Medial Femoral Condyle of the Knee Using Nonabsorbable Fixation Screws
Osteochondritis dissecans is a focal lesion of articular cartilage that can result in fragment instability with progression of early osteoarthritis. Regarding the knee joint, salvage of an unstable lesion can be achieved using arthroscopic-assisted reduction and fixation via a 2-stage process. The first involves arthroscopic fixation of the fragment using nonbioabsorbable screws, whereas the second stage performed 12 weeks later involves removal of the screws and confirmation of successful healing of the lesion. Previous studies have demonstrated excellent outcomes in patients undergoing fixation for unstable chondral lesions not amenable to conservative treatment. A critical component of successful treatment is understanding the importance of hardware placement and technique. The purpose of the Technical Note is to describe a method performing this 2-stage arthroscopic repair of an unstable chondral lesion located on the medial femoral condyle of the knee
Superior Gluteal Reconstruction for Severe Hip Abductor Deficiency
Abductor tendon tears are one of the common causes of recalcitrant laterally based hip pain and dysfunction. In most cases, abductor tendon tears are associated with chronic nontraumatic tearing of the gluteus medius tendon. Restoring abductor function of the hip by primary repair of the gluteus medius tendon has been reported to have good and excellent outcomes. However, primary repair might not be as effective for chronic detachment of the gluteus medius tendon with a wide separation from the femoral footprint or severe tendon loss. The lack of tendinous foot for repair and the intrinsically degenerative condition of the tendon may create high tension at the repair site thereby predisposing to surgical failure. We believe that the use of soft-tissue allograft from the Achilles tendon or human dermal allograft may help strengthen the surgical site. We describe a superior gluteal reconstruction technique that is suitable for cases with abductor tendon tear with severe tendon loss
Reconstruction Guide for the Measurement of Segmental Labral Insufficiency: An Alternative Technique for Acetabular Labral Reconstruction
The acetabular labrum is a dynamic structure important for both hip stability and functional motion. Given its importance, injuries to the labrum result in significant symptomatic dysfunction caused by altered hip kinematics. Although labral repair represents the standard for symptomatic labral tears with underlying bony deformity, complex labral tears or those with significant degeneration may not be amenable to repair and require labral reconstruction. Labral reconstruction has been shown to restore intra-articular fluid pressurization to levels similar to those in the intact state, and cohort studies have increasingly demonstrated significant improvement in patient-reported outcomes at midterm follow-up. A critical component of successful labral reconstruction is accurate measurement of the graft length to restore native anatomy and kinematics of the hip. The purpose of this Technical Note is to describe a way to accurately measure graft length required for labral reconstruction
Endoscopic Repair of Proximal Hamstring Tear With Double-Row Suture Bridge Construct
Hamstring strains account for 25% to 30% of all muscle strains and are an exceedingly common injury in the athletic population. Although proximal hamstring avulsion injuries occur less commonly than strains at the myotendinous junction, they are more severe and debilitating. Proximal hamstring avulsions do not respond well to conservative treatment and are more likely to require surgical intervention. Surgical repair of proximal hamstring avulsions is indicated when the injury fails to respond to conservative treatment, in cases of osseous avulsion with retraction, and in cases of tearing of all 3 hamstring tendons. Endoscopic repair of proximal hamstring avulsions is a promising technique to repair these injuries while reducing morbidity. We describe our technique for endoscopic proximal hamstring repair, which uses a double-row suture bridge construct to reattach the tendons to the ischial tuberosity
Contemporary Hip Capsular Management and Closure Using a Suture Passing Device
Before comprehensive correction of femoroacetabular impingement syndrome, capsular management must be thoughtfully considered to ensure both adequate visualization for bony resection and prevention of iatrogenic microinstability. A number of biomechanical and clinical studies have shown the importance of performing comprehensive capsular closure to restore native hip biomechanical kinematics. The purpose of this Technical Note is to describe the technique of using a suture passing device for capsular plication by a fellowship-trained hip arthroscopist at a large-volume academic center
