RESUMEN
Acetabular labral tears are commonly diagnosed in patients with hip or groin pain, most of which occur anterosuperiorly. In some cases, operative intervention in the form of arthroscopic labral repair may be necessary to restore labral function. Posterolateral tears can be technically challenging when using traditional modified anterior portal and anterolateral (AL) portal access owing to a suboptimal drill trajectory. In this article, we describe the establishment of a posterolateral (PL) portal 1 to 2 cm posterior to the tip of the greater trochanter, mirroring the distal-to-proximal trajectory of the AL portal and entering the capsulotomy at the 10-o'clock position. This method highlights that the PL portal is used for drilling and anchor placement, whereas the remaining work is performed through the AL portal. This avoids the use of any shavers or burrs in the PL portal near important neurovascular structures, including the sciatic nerve. Addressing posterolateral labral tears in the 9- to 11-o'clock position using a PL portal can enhance labral fixation, thereby mitigating the risk of suboptimal repairs that can negatively impact postoperative outcomes.
RESUMEN
BACKGROUND: Osteochondral allograft (OCA) transplantation is an important surgical technique for full-thickness chondral defects in the knee. For patients undergoing this procedure, topography matching between the donor and recipient sites is essential to limit premature wear of the OCA. Currently, there is no standardized process of donor and recipient graft matching. PURPOSE: To evaluate a novel topography matching technique for distal femoral condyle OCA transplantation using 3-dimensional (3D) laser scanning to create 3D-printed patient-specific instrumentation in a human cadaveric model. STUDY DESIGN: Descriptive laboratory study. METHODS: Human cadaveric distal femoral condyles (n = 12) underwent 3D laser scanning. An 18-mm circular osteochondral recipient defect was virtually created on the medial femoral condyle (MFC), and the position and orientation of the best topography-matched osteochondral graft from a paired donor lateral femoral condyle (LFC) were determined using an in silico analysis algorithm minimizing articular step-off distances between the edges of the graft and recipient defect. Distances between the entire surface of the OCA graft and the underneath surface of the MFC were evaluated as surface mismatch. Donor (LFC) and recipient (MFC) 3D-printed patient-specific guides were created based on 3D reconstructions of the scanned condyles. Through use of the guides, OCAs were harvested from the LFC and transplanted to the reamed recipient defect site (MFC). The post-OCA recipient condyles were laser scanned. The 360° articular step-off and cartilage topography mismatch were measured. RESULTS: The mean cartilage step-off and graft surface mismatch for the in silico OCA transplant were 0.073 ± 0.029 mm (range, 0.005-0.113 mm) and 0.166 ± 0.039 mm (range, 0.120-0.243 mm), respectively. Comparatively, the cadaveric specimens postimplant had significantly larger step-off differences (0.173 ± 0.085 mm; range, 0.082-0.399 mm; P = .001) but equivalent graft surface topography matching (0.181 ± 0.080 mm; range, 0.087-0.396 mm; P = .678). All 12 OCA transplants had mean circumferential step-off differences less than a clinically significant cutoff of 0.5 mm. CONCLUSION: These findings suggest that the use of 3D-printed patient-specific guides for OCA transplantation has the ability to reliably optimize cartilage topography matching for LFC to MFC transplantation. This study demonstrated substantially lower step-off values compared with previous orthopaedic literature when also evaluating LFC to MFC transplantation. Using this novel technique in a model performing MFC to MFC transplantation has the potential to yield further enhanced results due to improved radii of curvature matching. CLINICAL RELEVANCE: Topography-matched graft implantation for focal chondral defects of the knee in patients improves surface matching and has the potential to improve long-term outcomes. Efficient selection of the allograft also allows improved availability of the limited allograft sources.
RESUMEN
PURPOSE: To assess the consistency and quality of risk factor reporting for rotator cuff repair (RCR) retear and identify risk factors most frequently associated with retear. METHODS: A systematic review with PRISMA guidelines was performed. Of the initial 3,158 titles, a total of 31 studies met the following inclusion criteria: (1) clinical studies regarding RCR failure, (2) arthroscopic procedures involving RCR, (3) reporting clinical outcomes (4) performed within 5 years (5) and studies investigating pre-operative risk factors for retear. After full-text review, 18 risk factors were analyzed. RESULTS: The most consistently significant risk factors were acromiohumeral distance (AHD) (80%), critical shoulder angle (CSA) (67%), tear size (63%), anterior/posterior (AP) dimension (60%), fatty infiltration (FI, 58%), and retraction size (56%). FI was analyzed using different methods between studies with 63% finding significant results and 50% of all studies performing ordinal analysis. Tear size was inconsistently analyzed quantitatively or qualitatively, with 58% finding significant results and 63% of all studies analyzing quantitatively. Risk factors consistently found to be non-significant included age, sex, diabetes mellitus (DM), symptom duration, hand dominance, repair technique, smoking and body mass index (BMI). CONCLUSIONS: Tear size, fatty infiltration, and retraction size were found to be significant risk factors in the majority of included studies evaluating rotator cuff retear. Risk factors less likely reported as predictive included repair technique, age, sex, DM, symptom duration, hand dominance, repair technique, smoking, and BMI. Risk factors that require further investigation include CSA, AHD, and AP tear dimension. Level III, systematic review of Level III-V studies.
RESUMEN
Purpose: To report the clinical outcomes and reoperation rates of arthroscopic and endoscopic iliopsoas release at short-term follow-up after ipsilateral total hip arthroplasty (THA) at 2 separate medical institutions and to evaluate whether demographic and radiographic parameters are associated with postoperative patient-reported outcomes (PROs). Methods: Patients with iliopsoas tendinitis in the setting of prior THA who underwent arthroscopic iliopsoas fractional lengthening from 1988 to 2023 at 2 academic institutions were reviewed. Patients were included if they had 12 months of follow-up and underwent evaluation of preoperative anterior acetabular component overhang, surgery satisfaction, postoperative subjective hip flexion strength and anterior groin pain improvement, modified Harris Hip Score, Single Assessment Numeric Evaluation score, Tegner activity scale score, visual analog scale (VAS) score, and revision hip arthroplasty. Results: Sixty hips in 58 patients (19 male and 39 female patients) were followed up for a mean of 39.3 months (range, 12.0-105.9 months) postoperatively. Of the patients, 77% reported feeling "much better" or "slightly better," 75% reported improved anterior groin pain, and 60% reported improved subjective hip flexion strength. The surgery satisfaction rating was 7.2 ± 3.3 (scale of 0 to 10). The mean postoperative modified Harris Hip Score, VAS score for pain at rest, VAS score for pain with use, and Single Assessment Numeric Evaluation score were 73.9 ± 19.4, 1.3 ± 2.4, 3.8 ± 2.9, and 71.9 ± 21.9, respectively. Preoperative anterior acetabular component overhang was 3.3 ± 6.5 mm and did not significantly correlate with postoperative PROs (P ≥ .45). The Tegner score improved from 2.5 ± 1.7 preoperatively to 2.9 ± 1.4 postoperatively (P = .0253). Three patients underwent revision arthroplasty at a mean of 25.3 months (range, 11.6-40.4 months) postoperatively, with an acetabular component revision rate of 3.3%. Conclusions: Satisfactory outcomes and low revision arthroplasty rates were observed in patients undergoing arthroscopic iliopsoas lengthening after THA. There was no statistically significant relation between anterior acetabular component overhang and final PROs. Level of Evidence: Level IV, therapeutic case series.
RESUMEN
The hip capsule is the primary stabilizer of the hip joint. At the time of hip arthroscopy, the capsule is disrupted to obtain intra-articular access and proper joint visualization. With the number of patients undergoing primary and revision hip arthroscopy continuing to increase, it is not uncommon for surgeons to encounter patients with iatrogenic capsular deficiency from prior hip arthroscopy. In cases where substantial capsular defects beyond the scope of capsular repair are visualized, reconstruction may be required to obtain satisfactory closure and restore hip stability. We present a step-by-step workflow for efficient hip capsular reconstruction with rectus overlay while allowing for facile incorporation of other revision procedures such as labral repair and femoral osteochondroplasty.
RESUMEN
To define Minimally Clinically Important Difference (MCID) and Patient Acceptable Symptomatic State (PASS) threshold scores after open gluteus medius and/or minimus repair. Primary open gluteus medius and/or minimus repair patients from November 2013 to March 2020 were identified. Patient reported outcomes (PROs) were assessed preoperatively, 1- and 2-year follow-up, including the Hip Outcome Score Activities of Daily Living (HOS-ADL), modified Harris Hip Score (mHHS), International Hip Outcome Tool-12 (iHOT-12) and Visual Analog Scale (VAS) Pain. Thresholds for achieving a MCID and PASS postoperatively were calculated using the distribution method and receiver operator curve analysis; 25 patients (24 females, 1 male, age: 69 ± 6.8 years, body mass index: 26.9 ± 5.0 kg/m2) were included in final analyses. MCID threshold scores for HOS-ADL, mHHS, iHOT-12 and VAS Pain were calculated as 11.1, 6.2, 15.3 and 14.0, respectively. PASS threshold scores for each of the PROs were as follows: HOS-ADL (71.9), mHHS (60.0), iHOT-12 (49.2) and VAS Pain (36.8). MCID thresholds for HOS-ADL, mHHS, iHOT-12 and VAS Pain were achieved by 58.3%, 83.3%, 66.7% and 57.1% of patients, respectively. PASS thresholds for HOS-ADL, mHHS, iHOT-12 and VAS Pain were achieved by 52.4%, 44.8%, 65% and 59.1% of patients, respectively. Open gluteus medius and/or minimus repair results in a high rate of achievement of clinically significant outcomes at a minimum of 2 years postoperatively. MCID threshold values for HOS-ADL, mHHS, iHOT-12 and VAS Pain were 11.1, 6.2, 15.3 and 14.0, respectively. PASS threshold values for HOS-ADL, mHHS, iHOT-12 and VAS Pain were 71.9, 60.0, 49.2 and 36.8, respectively. The majority of patients achieved clinically significant outcomes with 81.3% and 77.3% achieving MCID and PASS for at least one PRO, respectively.
RESUMEN
Cartilage injuries can present in a diverse setting of anatomic locations, with varying severity, and can impact athletes of all ages and competition levels. Moreover, the timing of when an injury presents introduces an additional dimension to treatment decision-making. Frequently, the level of competition, in conjunction with career trajectory and short-term and long-term athlete goals, will dictate whether a temporary or definitive treatment strategy is ideal. Although indicating the correct therapeutic regimen may prove challenging, understanding the athlete-specific considerations can be essential to meeting the goals of the athlete and other stakeholders involved in the athlete's career. The purpose of this review is to comprehensively present the deliberations a treating physician must consider in managing cartilage injuries within a spectrum of athletic levels ranging from youth to professional levels, with a secondary focus on the presentation of temporizing treatment strategies and associated outcomes.

PURPOSE OF REVIEW: The purpose of this review is to summarize current clinical knowledge on the prevalence and types of meniscus pathology seen with concomitant anterior cruciate ligament (ACL) injury, as well as surgical techniques, clinical outcomes, and rehabilitation following operative management of these pathologies. RECENT FINDINGS: Meniscus pathology with concomitant ACL injury is relatively common, with reports of meniscus pathology identified in 21-64% of operative ACL injuries. These concomitant injuries have been associated with increased age and body mass index. Lateral meniscus pathology is more common in acute ACL injury, while medial meniscus pathology is more typical in chronic ACL deficiency. Meniscus tear patterns associated with concomitant ACL injury include meniscus root tears, lateral meniscus oblique radial tears of the posterior horn (14%), and ramp lesions of the medial meniscus (8-24%). These meniscal pathologies with concomitant ACL injury are associated with increased rotational laxity and meniscal extrusion. There is a paucity of comparative studies to determine the optimal meniscus repair technique, as well as rehabilitation protocol, depending on specific tear pattern, location, and ACL reconstruction technique. There has been a substantial increase in recent publications demonstrating the importance of meniscus repair at the time of ACL repair or reconstruction to restore knee biomechanics and reduce the risk of progressive osteoarthritic degeneration. Through these studies, there has been a growing understanding of the meniscus tear patterns commonly identified or nearly missed during ACL reconstruction. Surgical management of meniscal pathology with concomitant ACL injury implements the same principles as utilized in the setting of isolated meniscus repair alone: anatomic reduction, biologic preparation and augmentation, and circumferential compression. Advances in repair techniques have demonstrated promising clinical outcomes, and the ability to restore and preserve the meniscus in pathologies previously deemed irreparable. Further research to determine the optimal surgical technique for specific tear patterns, as well as rehabilitation protocols for meniscus pathology with concomitant ACL injury, is warranted.
RESUMEN
Background: While the biomechanical properties of the native medial patellofemoral ligament (MPFL) have been well studied, there is no comprehensive summary of the biomechanics of MPFL reconstruction (MPFLR). An accurate understanding of the kinematic properties and functional behavior of current techniques used in MPFLR is imperative to restoring native biomechanics and improving outcomes. Purpose: To provide a comprehensive review of the biomechanical effects of variations in MPFLR, specifically to determine the effect of graft choice and reconstruction technique. Study Design: Systematic review. Methods: A systematic review was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A total of 32 studies met inclusion criteria: (1) using ≥8 human cadaveric specimens, (2) reporting on a component of MPFLR, and (3) having multiple comparison groups. Results: Gracilis, semitendinosus, and quadriceps grafts demonstrated an ultimate load to failure (N) of 206.2, 102.8, and 190.0 to 205.0 and stiffness (N/mm) of 20.4, 8.5, and 21.4 to 33.6, respectively. Single-bundle and double-bundle techniques produced an ultimate load to failure (N) of 171 and 213 and stiffness (N/mm) of 13.9 and 17.1, respectively. Anchors placed centrally and superomedially in the patella produced the smallest degree of length changes throughout range of motion in contrast to anchors placed more proximally. Sutures, suture anchors, and transosseous tunnels all produced similar ultimate load to failure, stiffness, and elongation data. Femoral tunnel malpositioning resulted in significant increases in contact pressures, patellar translation, tilt, and graft tightening or loosening. Low tension grafts (2 N) most closely restored the patellofemoral contact pressures, translation, and tilt. Graft fixation angles variably and inconsistently altered contact pressures, and patellar translation and tilt. Conclusion: Data demonstrated that placement of the MPFLR femoral tunnel at the Schöttle point is critical to success. Femoral tunnel diameter should be ≥2 mm greater than graft diameter to limit graft advancement and overtensioning. Graft fixation, regardless of graft choice or fixation angle, is optimally performed under minimal tension with patellar fixation at the medial and superomedial patella. However, lower fixation angles may reduce graft strain, and higher fixation angles may exacerbate anisometry and length changes if femoral tunnel placement is nonanatomic.
RESUMEN
Labral tears most commonly occur anteriorly between the 12- and 3-o'clock positions, with the 12-o'clock position denoted as superior and the 3-o'clock position denoted as anterior. When approaching the 3-o'clock position and beyond, suture anchor placement becomes difficult given the challenging arthroscopic trajectory and an overall thin anterior rim of cortical bone for anchor purchase, resulting in a narrow angle of safe drilling. The purpose of this technical note is to present a safe and reproducible method of suture anchor placement during acetabular labral repair approaching the 3- and 4-o'clock positions, with the 12-o'clock position representing the superior anatomic location and the 3-o'clock position representing the anterior anatomic location regardless of hip laterality. We use an inside-out anchor placement technique to place far medial anchors, which differs from the conventional techniques (e.g., outside-in technique) in which anchor placement is performed along the external margin of the acetabular labrum.
RESUMEN
Background: Patients with isolated anterior cruciate ligament (ACL) reconstruction have demonstrated an increased risk of ACL graft failure and lower patient-reported outcome (PRO) scores when increased posterior tibial slope (PTS) is present. However, there is a paucity of literature evaluating the effect of PTS on outcomes after combined bicruciate multiligamentous knee reconstruction. Purpose: To determine whether differences exist for graft failure rates or PRO scores based on PTS after combined bicruciate multiligamentous knee reconstruction. Study Design: Cohort study; Level of evidence, 3. Methods: All patients who underwent combined ACL and posterior cruciate ligament (PCL) reconstruction between 2000 and 2020 at our institution were identified. Exclusion criteria were age <18 years, knee dislocation grade 5 injuries, concomitant osteotomy procedures, and <2 years of clinical follow-up. Demographic and outcomes data were collected from our prospectively gathered multiligamentous knee injury database. Lysholm and International Knee Documentation Committee (IKDC) scores were analyzed in relation to PTS. Outcomes were compared for patients with a PTS above and below the mean for the total cohort, PTS >12° versus <12°, positive versus negative Lachman test at follow-up, and positive versus negative posterior drawer test at follow-up. Results: A total of 98 knees in 98 patients were included in the study, with a mean clinical follow-up of 5.1 years (median, 4.6 years; range, 2-16 years). The mean PTS was 8.7° (range, 0.4°-16.9°). Linear regression analysis showed no significant correlation between PTS and IKDC or Lysholm scores. Patients with a PTS above the mean of 8.7° trended toward lower IKDC (P = .08) and Lysholm (P = .06) scores. Four patients experienced ACL graft failure and 5 patients experienced PCL graft failure. There were no differences in graft failure rates or PRO scores for patients with a PTS >12°. Patients with a positive Lachman test trended toward higher PTS (9.6° vs 8.5°, P = .15). Conclusion: In this series of bicruciate multiligamentous knee reconstructions at midterm follow-up, no differences in graft failures, complications, reoperations, revisions, or PRO scores based on PTS were identified. Patients with a positive Lachman test were found to have a slightly higher PTS, although this did not reach statistical significance.
RESUMEN
PURPOSE: The demographic and radiological risk factors of subchondral insufficiency fractures of the knee (SIFK) continue to be a subject of debate. The purpose of this study was to associate patient-specific factors with SIFK in a large cohort of patients. METHODS: Inclusion criteria consisted of patients with SIFK as verified on magnetic resonance imaging (MRI). All radiographs and MRIs were reviewed to assess characteristics such as meniscus tear presence and type, subchondral oedema presence and location, location of SIFK, mechanical limb alignment, osteoarthritis as assessed by Kellgren-Lawrence grade and ligamentous injury. A total of 253 patients (253 knees) were included, with 171 being female. The average body mass index (BMI) was 32.1 ± 7.0 kg/m2. RESULTS: SIFK was more common in patients with medial meniscus tears (77.1%, 195/253) rather than tears of the lateral meniscus (14.6%, 37/253) (p < 0.001). Medial meniscus root and radial tears of the posterior horn were present in 71.1% (180/253) of patients. Ninety-one percent (164/180) of medial meniscus posterior root and radial tears had an extrusion ≥3.0 mm. Eighty-one percent (119/147) of patients with SIFK on the medial femoral condyle and 86.8% (105/121) of patients with SIFK on the medial tibial plateau had a medial meniscus tear. Varus knees had a significantly increased rate of SIFK on the medial femoral condyle in comparison to valgus knees (p = 0.016). CONCLUSION: In this large cohort of patients with SIFK, there was a high association with medial meniscus root and radial tears of the posterior horn, meniscus extrusion ≥3.0 mm as well as higher age, female gender and higher BMI. Additionally, there was a particularly strong association of medial compartment SIFK with medial meniscus tears. As SIFK is frequently undiagnosed, identifying patient-specific demographic and radiological risk factors will help achieve a prompt diagnosis. LEVEL OF EVIDENCE: Level IV.
RESUMEN
Meniscal extrusion (ME) is a valuable, noninvasive diagnostic tool for meniscus pathology. In addition, ultrasound can allow for instant results in the office. However, ME is a fragile metric in the degree of millimeters. The inconsistent techniques used by different authors in the literature and the additional operator variability that ultrasound technology introduces make it important a systematic approach is used. The purpose of this study is to propose a reproducible technique. The current authors recommend having the patient in (1) 30° of knee flexion while weight-bearing, (2) capturing the image at the posterior border of the medial collateral ligament, (3) using a reference line parallel to the articular margin of the tibia, and (4) measuring ME at the coronal midpoint of the outermost edge of the meniscus.
RESUMEN
CASE: A 20-year-old woman presented with a unipolar, 1.8 × 1.8-cm osteochondral defect of the left acetabulum. Osteochondral allograft transplantation was performed using a medial tibial plateau allograft resulting in excellent clinical outcomes across 4 different outcome scores and maintenance of the joint space at 4.3 years postoperatively. CONCLUSION: Although previous literature has demonstrated long-term clinical success of osteochondral allograft transplantation in knee, excellent clinical outcomes can also be obtained in the hip. Thus, osteochondral allograft transplantation may be a viable treatment option for adolescents and young adults with concomitant cartilage and subchondral bone hip defects.

Capsular management in hip arthroscopy has recently become a popular topic in the literature. Various approaches have been developed around the critical balance between safe and satisfactory exposure while maintaining hip joint stability and the restoration of capsular integrity at the conclusion of the case. Advocates for capsular closure recognize the role of the capsule in providing hip joint stability and aim to reestablish normal hip biomechanics through capsule preservation. Several recent studies have also shown capsular management strategies to influence both clinical outcomes and risk of revision surgery. We present an effective method for capsular management in hip arthroscopy that consistently allows excellent exposure and working space while allowing for facile, anatomic closure.
RESUMEN
Anterior cruciate ligament (ACL) reconstruction using the quadriceps tendon (QT) autograft is an increasingly utilized technique that confers less donor site morbidity and comparable outcomes to other historically used graft options. The graft harvest and implantation process present vast variability-particularly regarding the achievement of adequate graft site visualization, consistently attaining a uniform and appropriately sized graft, and subsequent reconstruction of the ACL with the all-soft tissue graft. The purpose of this Technical Note and video is to describe and demonstrate minimally invasive quadriceps tendon autograft harvesting using the Quadriceps Tendon Harvest Guide System (QUADTRAC), and its subsequent implantation within a single-bundle ACL reconstruction with suspensory fixation.
RESUMEN
BACKGROUND: Hip arthroscopy is rapidly advancing, with positive published outcomes at short- and midterm follow-up; however, available long-term data remain limited. PURPOSE: To evaluate outcomes of primary hip arthroscopy at a minimum 10-year follow-up at 2 academic centers by describing patient-reported outcomes and determining reoperation and total hip arthroplasty (THA) rates. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients with primary hip arthroscopy performed between January 1988 and April 2013 at 2 academic centers were evaluated for postoperative patient-reported outcomes-including the visual analog scale, Tegner Activity Scale score, Hip Outcome Score Activities of Daily Living and Sport Specific subscales, modified Harris Hip Score, Nonarthritic Hip Score, 12-item International Hip Outcome Tool, surgery satisfaction, and reoperations. RESULTS: A total of 294 patients undergoing primary hip arthroscopy (age, 40 ± 14 years; 66% women; body mass index, 27 ± 6) were followed for 12 ± 3 years (range, 10-24 years) postoperatively. Labral debridement and repair were performed in 41% and 59% of patients, respectively. Of all patients who underwent interportal capsulotomy, 2% were extended to a T-capsulotomy, and 11% underwent capsular repair. At final follow-up, patients reported a mean visual analog scale at rest of 2 ± 2 and with use of 3 ± 3, a 12-item International Hip Outcome Tool of 68 ± 27, a Nonarthritic Hip Score of 81 ± 18, a modified Harris Hip Score of 79 ± 17, and a Hip Outcome Score Activities of Daily Living of 82 ± 19 and Sport Specific subscale of 74 ± 25. The mean surgical satisfaction was 8.4 ± 2.4 on a 10-point scale, with 10 representing the highest level of satisfaction. In total, 96 hips (33%) underwent reoperation-including 65 hips (22%) converting to THA. THA risk factors included older age, higher body mass index, lower lateral center-edge angle, larger alpha angle, higher preoperative Tönnis grade, as well as labral debridement and capsular nonrepair (P≤ .039). Patients undergoing combined labral and capsular repair demonstrated a THA conversion rate of 3% compared with 31% for patients undergoing combined labral debridement and capsular nonrepair (P = .006). Labral repair trended toward increased 10-year THA-free survival (84% vs 77%; P = .085), while capsular repair demonstrated significantly increased 10-year THA-free survival (97% vs 79%; P = .033). CONCLUSION: At a minimum 10-year follow-up, patients undergoing primary hip arthroscopy demonstrated high satisfaction and acceptable outcome scores. In total, 33% of patients underwent reoperation-including 22% who underwent THA. Conversion to THA was associated with patient factors including older age, higher Tönnis grade, and potentially modifiable surgical factors such as labral debridement and capsular nonrepair.

Quadriceps tendon autografts are an increasingly popular choice for anterior cruciate ligament (ACL) reconstruction, with decreased donor-site morbidity alongside good patient outcomes. Although harvesting of the tendon can be done in a minimally invasive fashion, this introduces some difficulty with visualization and consistency of graft sizing. The purpose of this Technical Note and video is to provide a method of quadriceps tendon autograft harvesting using the Quadriceps Tendon Harvest Guide System (QUADTRAC) in a single-bundle ACL reconstruction.
RESUMEN
The medial collateral ligament serves as the primary stabilizer to valgus stress on the medial side of the knee and is the most commonly injured ligament in the knee. Medial collateral ligament reconstruction can provide improved stability and clinical outcomes for patients. Advancements in techniques, including the use of an adjustable-length-loop suspensory fixation device through a longitudinal incision, have been introduced in recent years. The purpose of this Technical Note and video is to provide a minimally invasive method for medial collateral ligament reconstruction with adjustable-loop femoral fixation and posteromedial corner plication.
