Project description: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.

Project description:The prevalence of hip arthroscopy has increased exponentially with the advent of arthroscopic labral repair techniques for femoroacetabular impingement. The goal of arthroscopic labral repair is to re-create the anatomic suction seal of the labrum against the femoral head. This important anatomic relationship has been demonstrated in several biomechanical studies. Performing the acetabular recession and evaluating the congruity of labral repairs during surgery is difficult with the application of traction distracting the femoral head from the chondrolabral junction. Additionally, prolonged traction risks nerve injury during hip arthroscopy. The purpose of this technique article is to describe a method of using traction only for central compartment work, and releasing the traction to allow the femoral head to reduce the labrum to its anatomic position for acetabular recession, anchor placement, and suture fixation. In this manner, the presented technique prevents an "out-of-round" or everted repair. This technique re-creates the native anatomy and biomechanics of the hip after acetabular recession and labral repair while decreasing traction time.

Project description:The goal of acetabular labral repair is to preserve/restore labral function. Maintaining labral function necessitates recreating the labrum's anatomy, especially avoiding a nonanatomic repair of the labrum to the acetabular rim. The purpose of this report is to detail the technique of acetabular labral repair using this Q-FIX all-suture anchor.

Project description:Lateral meniscus lesions result in loss of meniscus hoop stresses and can lead to lateral compartment overload and early degenerative changes. Arthroscopic suture repair provides good long-term results. However, posterior vertical tears in the peripheral area of the meniscus can be technically challenging to resolve. This Technical Note describes the suture hook technique using an accessory posterolateral portal. We believe it is a safe, effective method for repairing full vertical tears of the lateral meniscus.

Project description:Labral tears are the most common pathology in patients undergoing hip arthroscopy and the most common cause of mechanical hip symptoms. Labral repair techniques have been described in the literature using suture anchors placed as close as possible to the acetabular rim without penetrating the articular surface. Optimal surgical technique for labral repair is very important, and an inappropriate entry point and guide angulation may lead to intra-articular penetration of the anchor, chondral damage, anchor loosening, or inadequate fixation. A shallow dysplastic hip, the drilling trajectory, the narrow width of the acetabular rim, or some specific anatomic variations may generate difficulty during anchor placement. Suture anchors themselves have been associated with several significant complications, including rim fracture, osteolysis, enlargement of drill holes, and infection. The treatment of labral lesions with transosseous suture is an alternative to anchor use, eliminating the need for anchors and avoiding anchor-associated complications. This technique offers versatility to surgeons and is more cost-effective for patients and health services. We aim to describe the indications and technique for transosseous labral repair without anchors.

Project description:Pan-labral tears are relatively uncommon, but they present significant challenges to arthroscopists. The difficulty lies in the need to access the glenoid rim circumferentially for proper anchor placement. Traditionally, this requires that multiple portals and percutaneous access be established as needed. Additionally, proper preoperative planning is needed to accurately reduce the labrum. In this Technical Note, we demonstrate a technique that accomplishes circumferential access and a well-planned approach with 2 portals and a percutaneous cannula.

Project description:PurposeThe purpose of this study was to systematically review the evidence in the literature to ascertain whether acetabular labral repair (ALR) or debridement (ALD) resulted in superior patient outcomes.MethodsThe systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Peer-reviewed studies comparing ALR and ALD published in English with full text available were included. Patients undergoing both open and arthroscopic surgery in randomized controlled trials, prospective cohort studies, retrospective cohort studies, and case-control studies were included. Studies were quantified for methodological quality using the MINORS criteria. Clinical outcomes were compared, with qualitative analysis, and quantitative analyses were performed using GraphPad Prism version 7. A P value <.05 was considered to be statistically significant.ResultsThere were 8 studies included (level of evidence [LOE] I = 1; LOE II = 2; LOE III = 5). The 7 studies compared 364 patients (369 hips) with ALR to 318 patients (329 hips) with ALD, with a mean follow-up time ranging between 32-120 months. Five studies found significantly improved patient reported outcomes with ALR (Harris Hip Score, Merle d'Aubigné, Pain, SF-12). Several studies compared the outcomes after ALR and ALD and found statistical significance in all investigated metrics in favor of ALR. One study found a significant improvement in abduction but no other study found any difference in range of motion. No study found any difference in complication rate, revision rate or conversion to total hip arthroplasty. Although, 2 studies found ALR reduced the rate of osteoarthritic progression.ConclusionCurrent literature suggests that acetabular labral repair may result in superior patient reported outcomes. However, there appears to be no significant difference in the rate of progression to total hip arthroplasty at up to 10-year follow-up.Level of evidenceLevel III, systematic review of Level I, II, and III studies.

Project description:Posterior cruciate ligament (PCL) reconstruction using the transtibial drilling or arthroscopic tibial-inlay technique has a risk of injury to the popliteal neurovascular bundle because a pin is drilled anterior to posterior. Intraoperative fluoroscopy is used to decrease the risk of neurovascular injury. In addition, graft passage in the transtibial technique may be problematic because of a sharp turn when placing the graft into the tibial tunnel, which may damage graft fibers. In the surgical technique described in this report, the posteromedial portal is used for visualization and the posterolateral portal is used for debridement of the PCL tibial footprint and the synovial fold closest to the PCL. A curved guide is placed from the posterolateral portal to the tibial footprint, and a flexible pin is drilled across the tibia. The tibial tunnel is then created using a flexible reamer under direct visualization up to the desired length, and a graft can be positioned in the tibial tunnel through the posterolateral portal. This technique has the potential advantages of decreasing the risk of injury to the popliteal neurovascular bundle (use of anteriorly directed, inside-out drilling), avoiding a sharp turn during graft passage, and allowing accurate and anatomic tibial tunnel placement without intraoperative fluoroscopy.

Project description:Traditional techniques for acetabular osteoplasty in femoral acetabular impingement have required surgical detachment of the labrum at the chondrolabral junction. Such approaches compromise labral blood flow and contribute to a limited ability for healing at the chondrolabral junction. In this technical note and accompanying video, we present a technique for preservation of the chondrolabral junction during labral repair and acetabular osteoplasty. We elevate the chondrolabral complex subperiosteally off the acetabular rim, and the acetabular shelf is then contoured under fluoroscopic guidance. The labrum is then repaired and reconstituted to a new anatomic footprint. We find this technique to be advantageous because it preserves the blood flow to the labrum, thereby maximizing healing potential. Outcome studies are warranted to further elucidate the functional and outcome benefits of this surgical technique.

Project description:Posterior instability, although an uncommon shoulder pathology, is reported most frequently in the athletic population. Arthroscopic repair has emerged as the main surgical treatment modality for posterior instability. However, when compared with arthroscopic repair for anterior instability, the results of this procedure remain suboptimal. The creation of iatrogenic defects in the capsule, due to cannula placement, is a possible culprit. Because these defects typically do not heal satisfactorily, they become stress risers within the capsule itself, which may lead to recurrent instability or an otherwise compromised repair construct. Therefore, we find that routine intraoperative repair of these defects after repair can reduce the risk of injury and possibly improve long-term outcomes. In this article, we illustrate the repair of a posterior segmental tear using all-suture knotless implants with closure of the posterior and posterior-inferior portals after stabilization.
