Abstract

Background:

The anterolateral ligament (ALL) contributes to anterolateral rotational stability of the knee. Internal bracing of the anterior cruciate ligament (ACL) and ALL reinforces the ligaments and encourages natural healing by protecting both during the healing phase and supporting early mobilization.

Purpose/Hypothesis:

To assess the 2-year patient-reported outcomes of combined ACL repair and ALL internal brace augmentation. We hypothesized that significant improvements in outcomes would be seen.

Study Design:

Case series; Level of evidence, 4.

Methods:

A total of 43 consecutive patients with acute proximal ACL ruptures were prospectively evaluated for a minimum of 2 years. The mean age at the time of surgery was 25.7 years (range, 13-56 years). Indications for the combined ACL/ALL procedure were associated Segond fractures, grade 3 pivot shift, or high levels of sporting activity. Patients with chronic ruptures or with multiligament injuries were excluded. The Knee injury and Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain, Veterans RAND 12-Item Health Survey (VR-12), and Marx activity scale were collected preoperatively and at 12 and 24 months postoperatively. Patients with any postoperative complications were identified at the time of this analysis.

Results:

The mean follow-up period was 44.8 months. Five patients were lost to follow-up, leaving 38 patients (88.4%) in the final analysis. The mean KOOS for Pain, Symptoms, Activities of Daily Living, Sport/Recreation, and Quality of Life improved from a respective 64.9, 58.6, 75.0, 33.7, and 28.9 preoperatively to 91.1, 81.8, 96.1, 82.8, and 74.3 at the 2-year follow-up ( P < .0001). The mean WOMAC scores for pain, stiffness, and function improved from 77.5, 65.3, and 75.0 preoperatively to 94.6, 88.6, and 96.0 at the 2-year follow-up ( P < .0001). The VAS pain score improved from 3.4 preoperatively to 0.7 at the 2-year follow-up, and the VR-12 physical score improved from 34.4 preoperatively to 52.7 at the 2-year follow-up ( P < .0001 for both ). However, the Marx activity score decreased from 13.3 preinjury to 10.6 at the 2-year follow-up ( P = .01). Two patients (5.3%) sustained a rerupture.

Conclusion:

Combined ACL repair and ALL internal brace augmentation demonstrated excellent outcomes in 94.7% of the study patients. Based on our experience with this cohort as well as our isolated ACL repair data, we suggest that high-risk patients with ACL ruptures have an additional ALL procedure to provide rotational stability.

Anatomy of the anterolateral ligament of the knee.

Steven Claes, Evie Vereecke, Michael Maes … (2013)

In 1879, the French surgeon Segond described the existence of a 'pearly, resistant, fibrous band' at the anterolateral aspect of the human knee, attached to the eponymous Segond fracture. To date, the enigma surrounding this anatomical structure is reflected in confusing names such as '(mid-third) lateral capsular ligament', 'capsulo-osseous layer of the iliotibial band' or 'anterolateral ligament', and no clear anatomical description has yet been provided. In this study, the presence and characteristics of Segond's 'pearly band', hereafter termed anterolateral ligament (ALL), was investigated in 41 unpaired, human cadaveric knees. The femoral and tibial attachment of the ALL, its course and its relationship with nearby anatomical structures were studied both qualitatively and quantitatively. In all but one of 41 cadaveric knees (97%), the ALL was found as a well-defined ligamentous structure, clearly distinguishable from the anterolateral joint capsule. The origin of the ALL was situated at the prominence of the lateral femoral epicondyle, slightly anterior to the origin of the lateral collateral ligament, although connecting fibers between the two structures were observed. The ALL showed an oblique course to the anterolateral aspect of the proximal tibia, with firm attachments to the lateral meniscus, thus enveloping the inferior lateral geniculate artery and vein. Its insertion on the anterolateral tibia was grossly located midway between Gerdy's tubercle and the tip of the fibular head, definitely separate from the iliotibial band (ITB). The ALL was found to be a distinct ligamentous structure at the anterolateral aspect of the human knee with consistent origin and insertion site features. By providing a detailed anatomical characterization of the ALL, this study clarifies the long-standing enigma surrounding the existence of a ligamentous structure connecting the femur with the anterolateral tibia. Given its structure and anatomic location, the ALL is hypothesized to control internal tibial rotation and thus to affect the pivot shift phenomenon, although further studies are needed to investigate its biomechanical function.

Updated U.S. population standard for the Veterans RAND 12-item Health Survey (VR-12).

James Rothendler, William Rogers, Benjamin G Fincke … (2009)

The purpose of this project was to develop an updated U.S. population standard for the Veterans RAND 12-item Health Survey (VR-12). We used a well-defined and nationally representative sample of the U.S. population from 52,425 responses to the Medical Expenditure Panel Survey (MEPS) collected between 2000 and 2002. We applied modified regression estimates to update the non-proprietary 1990 scoring algorithms. We applied the updated standard to the Medicare Health Outcomes Survey (HOS) to compute the VR-12 physical (PCS((MEPS standard))) and mental (MCS((MEPS standard))) component summaries based on the MEPS. We compared these scores to PCS and MCS based on the 1990 U.S. population standard. Using the updated U.S. population standard, the average VR-12 PCS((MEPS standard)) and MCS((MEPS standard)) scores in the Medicare HOS were 39.82 (standard deviation [SD] = 12.2) and 50.08 (SD = 11.4), respectively. For the same Medicare HOS, the average PCS and MCS scores based on the 1990 standard were 1.40 points higher and 0.99 points lower in comparison to VR-12 PCS and MCS, respectively. Changes in the U.S. population between 1990 and today make the old standard obsolete for the VR-12, so the updated standard developed here is widely available to serve as such a contemporary standard for future applications for health-related quality of life (HRQoL) assessments.

Lateral Extra-articular Tenodesis Reduces Failure of Hamstring Tendon Autograft Anterior Cruciate Ligament Reconstruction: 2-Year Outcomes From the STABILITY Study Randomized Clinical Trial

Alan Getgood, Dianne Bryant, Robert C. Litchfield … (2020)

Persistent anterolateral rotatory laxity after anterior cruciate ligament (ACL) reconstruction (ACLR) has been correlated with poor clinical outcomes and graft failure. We hypothesized that a single-bundle, hamstring ACLR in combination with a lateral extra-articular tenodesis (LET) would reduce the risk of ACLR failure in young, active individuals. Randomized controlled trial; Level of evidence, 1. This is a multicenter, prospective, randomized clinical trial comparing a single-bundle, hamstring tendon ACLR with or without LET performed using a strip of iliotibial band. Patients 25 years or younger with an ACL-deficient knee were included and also had to meet at least 2 of the following 3 criteria: (1) grade 2 pivot shift or greater, (2) a desire to return to high-risk/pivoting sports, (3) and generalized ligamentous laxity (GLL). The primary outcome was ACLR clinical failure, a composite measure of rotatory laxity or a graft rupture. Secondary outcome measures included the P4 pain scale, Marx Activity Rating Scale, Knee injury Osteoarthritis and Outcome Score (KOOS), International Knee Documentation Committee score, and ACL Quality of Life Questionnaire. Patients were reviewed at 3, 6, 12, and 24 months postoperatively. A total of 618 patients (297 males; 48%) with a mean age of 18.9 years (range, 14-25 years) were randomized. A total of 436 (87.9%) patients presented preoperatively with high-grade rotatory laxity (grade 2 pivot shift or greater), and 215 (42.1%) were diagnosed as having GLL. There were 18 patients lost to follow-up and 11 who withdrew (~5%). In the ACLR group, 120/298 (40%) patients sustained the primary outcome of clinical failure, compared with 72/291 (25%) in the ACLR+LET group (relative risk reduction [RRR], 0.38; 95% CI, 0.21-0.52; P < .0001). A total of 45 patients experienced graft rupture, 34/298 (11%) in the ACLR group compared with 11/291 (4%) in the ACL+LET group (RRR, 0.67; 95% CI, 0.36-0.83; P < .001). The number needed to treat with LET to prevent 1 patient from graft rupture was 14.3 over the first 2 postoperative years. At 3 months, patients in the ACLR group had less pain as measured by the P4 ( P = .003) and KOOS ( P = .007), with KOOS pain persisting in favor of the ACLR group to 6 months ( P = .02). No clinically important differences in patient-reported outcome measures were found between groups at other time points. The level of sports activity was similar between groups at 2 years after surgery, as measured by the Marx Activity Rating Scale ( P = .11). The addition of LET to a single-bundle hamstring tendon autograft ACLR in young patients at high risk of failure results in a statistically significant, clinically relevant reduction in graft rupture and persistent rotatory laxity at 2 years after surgery.
