Arthroscopic Acetabular Microfracture With the Use of Flexible Drills: A Technique Guide

Chondral injuries of the hip joint are often symptomatic and affect patient activity level. Several procedures are available for addressing chondral injuries, including microfracture. Microfracture is a marrow-stimulating procedure, which creates subchondral perforation in the bone, allowing pluripotent mesenchymal stem cells to migrate from the marrow into the chondral defect and form fibrocartilaginous tissue. In the knee, microfracture has been shown to relieve pain symptoms. In the hip, microfracture has been studied to a lesser extent, but published studies have shown promising clinical outcomes. The depth, joint congruity, and geometry of the hip joint make microfracture technically challenging. The most common technique uses hip-specific microfracture awls, but the trajectory of impaction is not perpendicular to the subchondral plate. Consequently, the parallel direction of impaction creates poorly defined channels. We describe an arthroscopic microfracture technique for the hip using a flexible microfracture drill. The drill and angled guides simplify access to the chondral defect. The microfracture drill creates clear osseous channels, avoiding compaction of the surrounding bone and obstruction of the channels. Furthermore, this technique allows for better control of the angle and depth of the drill holes, which enhances reproducibility and may yield improved clinical outcomes

SLAP Lesions: Trends in Treatment

Purpose: To determine the trends in SLAP repairs over time, including patient age, and percentage of SLAP repairs versus other common shoulder arthroscopic procedures. Methods: The records of 4 sports or shoulder/elbow fellowship trained orthopaedic surgeons were used to identify the total number of common shoulder arthroscopic cases performed between 2004 and 2014 using current procedural terminology codes (CPT): 29822, 29823, 29826, 29827, 29806, 29807, 29825, and 29828. The number of SLAP repairs (CPT code 29807) as a combined or isolated procedure were recorded, and the classification of SLAP type was undertaken using operative reports. Patient age was recorded. Linear regression was used to determine statistical significance. Results: There were 9,765 patients who underwent arthroscopic shoulder procedures using the defined CPT codes between 2004 and 2014 by our 4 orthopaedic surgeons. Of these, 619 underwent a SLAP repair (6.3%); average age 31.2 AE 11.9. The age of patients undergoing SLAP repair significantly decreased over time (P < .001, R 2 ¼ 0.794). Most SLAP repairs were performed on type II SLAP tears (P ¼ .015, R 2 ¼ 0.503). The percentage of SLAP repairs compared with the total number of shoulder arthroscopic surgeries and total number of patients who underwent SLAP repair significantly decreased over time (P < .001, R 2 ¼ 0.832 and P ¼ .002, R 2 ¼ 0.674, respectively). Conversely, the number and percentage of biceps tenodeses are increasing over time (P ¼ .0024 and P ¼ .0099, respectively). Conclusions: Over the past 10 years, the total number of biceps tenodeses has increased, whereas the number and relative percentage of SLAP repairs within our practice have decreased. The average age of patients undergoing SLAP repair is decreasing, and most SLAP repairs are performed for type II SLAP tears. Level of Evidence: Level IV, therapeutic case series

The Posterolateral Portal: Optimizing Anchor Placement and Labral Repair at the Inferior Glenoid

The Bankart lesion is considered the critical lesion in anterior shoulder instability, in which the anteroinferior glenoid labrum separates from the glenoid rim. Technical advances in arthroscopy have ushered in a shift from open to arthroscopic Bankart repair. When one is performing an arthroscopic Bankart repair, proper portal placement is critical for success in labral preparation and anchor placement. Frequently, standard anterior portals are insufficient for inferior glenoid anchor placement and suture shuttling. The posterolateral portal—located 4 cm lateral to the posterolateral corner of the acromion—simplifies and improves anchor placement, trajectory, and anatomic capsulolabral repair of the inferior glenoid. We present our preferred technique for capsulolabral repair of the inferior glenoid

Perineal Post Padding Technique to Improve Hip Distraction in Tall Patients

Hip distraction is necessary for safe arthroscopic entry into the hip joint. Achieving sufficient distraction is difficult in exceedingly tall patients (>190.5 cm) because of size limitations of currently available hip distraction systems. Inadequate distraction can delay the surgical procedure and potentially lead to complications. By repurposing a foam head-positioning block, we report a safe and inexpensive positioning technique for extending the traction distance for tall patients by 2 inches
