Clinical and radiographic results of internal fixation of quadrilateral plate fractures of acetabulum.

INTRODUCTION: Quadrilateral plate (QLP) is a relatively thin bony structure located below the pelvic brim proximal to the hip joint, so management of its fractures is challenging. OBJECTIVES: Evaluation of the functional and radiological outcomes of internal fixation of quadrilateral plate acetabular fractures; comparison of two methods of fracture fixation. PATIENTS AND METHODS: A prospective multicentric study including 30 patients who underwent open reduction and internal fixation of QLP fractures through modified Stoppa approach. Patients were divided into two groups according to the method of fixation (anatomical QLP plate vs suprapectineal and infrapectineal plates). Post-operative quality of reduction was evaluated using Matta score. Radiographical assessment according Matta's grading criteria and clinical outcome assessment using the Harris Hip Score (HHS) were repeated at follow-up and at one year to assess displacement. RESULTS: Mean age of patients was 34.9 ± 12.1 years. After one year follow-up, clinically mean HHS was 88. ± 5.74. Radiologically post-operative reduction quality was anatomical in 21 (70%) patients, satisfactory in eight (26.7%) patients and unsatisfactory in one (3.3%) patient. Matta's grading at the last follow-up was excellent in 21 (70%) patients, good in six (20%), fair in two (6.7%) patients and poor in one (3.3%) patient. No significant difference was recorded between the two groups in terms of radiographical and clinical results and rate of complications. CONCLUSION: Accurate reduction of quadrilateral plate fracture with secure fixation through modified Stoppa approach provides good and reproducible outcomes with few complications regardless the type of the implant.

Arthroscopic and endoscopic techniques for iliopsoas release in THA are safe and effective: a systematic review of the literature.

BACKGROUND: Hip replacement surgery is highly effective in relieving pain and improving mobility in patients with various hip conditions. However, some patients develop groin pain after surgery, often due to iliopsoas impingement (IPI), which can be challenging to diagnose. Conservative treatments are initially recommended, but when these are not effective, surgical options may be considered. This study aims to evaluate the clinical outcomes, success and failure rates, revision rates, and complications associated with arthroscopic and endoscopic surgery for IPI, thereby providing a comprehensive understanding of the effectiveness and risks of these surgical interventions. MATERIALS AND METHODS: A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, including a thorough search of five main databases: PubMed, Scopus, Embase, Medline, and Cochrane. Eligible articles were meticulously evaluated according to predefined criteria for levels of evidence (LoE), with retrospective studies assessed using the Coleman Methodology Score (mCMS). This systematic review was registered in the International Prospective Registry of Systematic Reviews (PROSPERO). RESULTS: Among the 16 included studies, 431 patients with 434 hips underwent either endoscopic or arthroscopic tenotomy. Both techniques showed favorable outcomes, with arthroscopic tenotomy demonstrating slightly higher success rates than endoscopic tenotomy. Common complications included mild pain and occasional infections, with recurrence observed in some cases. Both techniques offer direct visualization of prosthetic components and potential preservation of psoas function. CONCLUSIONS: Arthroscopic and endoscopic iliopsoas tenotomy are effective treatments for alleviating symptoms and improving hip function in patients with IPI post-total hip arthroplasty (THA). LEVEL OF EVIDENCE: IV.

An In Vivo Radiologic Description of Periacetabular Vascularization in a Healthy Subject and a Literature Review of its Clinical Implications.

The aim of this study is to provide a radiologic description of periacetabular vascularization. A computed tomography angiography was used to analyze the vascularization patterns of the periacetabular region, describing for the first time "in vivo" the periacetabular branches of the superior and inferior gluteal artery, obturator artery, and of the medial circumflex femoral artery. The analysis revealed the possibility of visualizing clearly all the previously described vessels of the aforementioned arteries. Both acetabular and supra-acetabular arteries, the rami of the OA directed to the lamina quadrilateral, and the rami of the IGA directed to the posterior wall were identified. In conclusion, understanding the periacetabular vascularization patterns is pivotal for effective clinical decision-making in pelvic trauma, and conservative and reconstructive surgery of the hip. The radiologic description provided in this study, along with the associated literature review, offers valuable insights into the clinical implications of periacetabular vascularization.

The Use of Barbed Sutures in Total Hip Arthroplasty: A Systematic Review on Clinical-Surgical Outcomes, Costs, and Complications.

PURPOSE: Total hip arthroplasty is among the most successful procedures in orthopaedic surgery. As the total number of total hip arthroplasties is constantly rising and it is expected to further increase, efforts oriented to optimise surgical pathways are investigated, aiming to reduce complications and diminish costs. The wound suturing phase is one of the steps that may be addressed. Barbed sutures have proved to reduce surgical times and enhance suture stability, then reducing wound-related complications in many surgical fields. The evidence on the use of this technology in total hip arthroplasty is still sparse, and its effect on patient outcomes and costs must still be clarified. METHODS: A systematic search of studies published from 1 January 2000 to 1 March 2023 was performed. Two authors independently reviewed the literature available in eight electronic databases to identify papers eligible for inclusion. RESULTS: A total of nine studies investigating 6959 procedures on 6959 patients were included in the final analysis. Five studies were randomised controlled trials, and the overall quality of studies ranged from moderate to high. The mean age of patients ranged from 43.8 to 70 years. BMI ranged from 25 to 31.9 kg/m2. The mean follow-up of studies ranged from 3 to 6 months. CONCLUSIONS: Evidence included in the systematic review suggested that the use of barbed sutures is associated with lower suturing times, complication rates, and overall costs when compared to the use of traditional suturing techniques. LEVEL OF EVIDENCE: II, systematic review of level I and II studies.

Challenges in Total Hip Arthroplasty with Prior Spinal Arthrodesis: A Comprehensive Review of Biomechanics, Complications, and Surgical Strategies.

Total hip arthroplasty (THA) has revolutionized patients' lives with hip osteoarthritis. However, the increasing prevalence of THA in individuals with prior lumbar arthrodesis (LA) poses unique challenges. This review delves into the biomechanical alterations, complications, and surgical strategies specific to this patient subset, highlighting the need for tailored preoperative assessments and planning. Due to altered pelvic and spinal biomechanics, patients with LA undergoing THA face a higher risk of dislocation and revision. The complex interplay between spinal and hip biomechanics underscores the need for meticulous preoperative planning. Comprehensive clinical examination and radiographic evaluation are vital for understanding patient-specific challenges. Various radiographic techniques, including computed tomography (CT)/X-ray matching and standing/seated studies, provide insights into postural changes affecting pelvic and spinal alignment. Complications following THA in patients with LA highlight the necessity for personalized surgical strategies. Careful consideration of implant selection, the surgical approach, and component positioning are essential to prevent complications. In summary, THA in patients with prior LA demands individualized preoperative assessments and planning. This approach is crucial to optimize outcomes and mitigate the heightened risks of complications, underlining the importance of tailored surgical strategies.

Can we encourage the endoscopic treatment for external snapping hip (ESH)? A systematic review of current concepts.

BACKGROUND: Snapping hip syndrome (SHS) is characterized by snapping sensation and pain and affects up to 10% of the general population. External snapping hip syndrome (ESHS), the most common form, is often due to repetitive movements in sports or anatomical predispositions. Conservative treatment includes physiotherapy and corticosteroid injections, while surgery is considered if conservative measures fail. Open surgical techniques carry several risks, while modern arthroscopic techniques offer less invasive options, such as endoscopic iliotibial band release (ITB) and gluteus maximus tenotomy. MATERIALS AND METHODS: A systematic review was conducted adhering to the PRISMA guidelines. Relevant studies were searched in four databases: Pubmed, Scopus, Embase, and Medline. The selected articles were evaluated according to the criteria of levels of evidence. The Risk of Bias In Non-randomized Studies of Interventions (ROBINS-I) was used to analyze the retrospective studies. This paper was registered in the International Prospective Registry of Systematic Reviews (PROSPERO). RESULTS: Out of 9 included studies, 403 patients with 689 hips underwent endoscopic treatment. ITB release and his variations were the main surgical techniques. Gluteus maximus tenotomy was also used in some studies. Postoperative rehabilitation protocols varied. Patients generally experienced significant improvements in symptoms and functional outcomes, with low rates of recurrence (1.02%) and revision (0.15%). Complications were minimal. CONCLUSIONS: Endoscopic treatment of ESH shows favorable results, improving functional outcomes and returning patients to pre-injury activity levels. Long-term efficacy and costeffectiveness need to be evaluated, emphasizing the importance of large-scale prospective randomized trials to clarify surgery's benefits in refractory ESH cases.

Tibial plateau fractures are associated with ligamentous and meniscal injuries. Preoperative evaluation of magnetic resonance imaging influences surgical treatment.

BACKGROUND: Tibial plateau fractures (TPFs) are usually associated with ligamentous or meniscal injuries that could remain misdiagnosed. An appropriate and early recognition may change the surgical management of these soft tissue injuries (STIs) that could be addressed concomitantly with TPF treatment. Magnetic resonance imaging (MRI) is an efficient diagnostic test to identify all associated STIs in TPFs. This study aims to analyze the MRI impact in identifying and guiding the STIs treatment in TPFs. MATERIAL/METHODS: This retrospective study included a consecutive series of 57 patients with TPFs treated between January 1st, 2022, and December 31st, 2022. All fracture patterns were classified according to the AO/OTA and Schatzker classification. The prevalence of STIs, including medial meniscus (MM), lateral meniscus (LM), anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL) injuries, was assessed through the MRI evaluation. RESULTS: A statistical significance was found regarding the MRI detection of LM, ACL, PCL and MCL injuries that led to additional surgical procedures at the same time as the TPFs treatment (p < 0.05). In contrast, the amount of additional MM and LCL injuries identified by MRI, which resulted in other surgical procedures, was not statistically significant (p > 0.05). CONCLUSIONS: Preoperative MRI has been demonstrated to be an effective procedure for diagnosing STIs in TPFs, significantly influencing and changing the surgical treatment. LEVEL OF EVIDENCE: IV.

Endoscopic management of greater trochanteric pain syndrome (GTPS): a comprehensive systematic review.

BACKGROUND: Greater trochanteric pain syndrome (GTPS) presents challenges in clinical management due to its chronic nature and uncertain etiology. Historically attributed to greater trochanteric bursitis, current understanding implicates abductor tendinopathy as the primary cause. Diagnosis usually involves a clinical examination and additional tests such as imaging and provocative testing. Surgical intervention may be considered for cases refractory to conservative therapy, with endoscopic techniques gaining ground over open procedures. MATERIALS AND METHODS: A systematic review was conducted adhering to the PRISMA guidelines. Relevant studies were searched in four databases: Pubmed, Scopus, Embase, and Medline. The selected articles were evaluated according to the criteria of levels of evidence (LoE). The Coleman methodology score (mCMS) was used to analyze the retrospective studies. This systematic review was registered in the International Prospective Registry of Systematic Reviews. RESULTS: Surgical success rates ranged from 70.6-100%, significantly improving pain and function. Complications were generally mild, mainly hematomas and seromas, while recurrence rates were low. However, limitations such as the retrospective design and the absence of control groups warrant cautious interpretation of the results. CONCLUSIONS: Endoscopic surgery emerges as a promising option for refractory GTPS, offering effective symptom relief and functional improvement. Despite limitations, these results suggest a favorable risk-benefit profile for endoscopic procedures. Further research is needed, particularly prospective randomized trials, to confirm these findings and optimize surgical techniques to improve patient outcomes.

Arthroscopic Reduction and Fixation of a Pipkin Type-I Femoral Head Fracture.

Background: This video article describes the technique for arthroscopic reduction and fixation of Pipkin type-I fractures. Description: Surgery is performed with the patient in a supine position, with free lower limbs, on a radiolucent table. Arthroscopic superior and anterolateral portals are made similarly to the portals created to evaluate the peripheral compartment during an outside-in (ballooning) technique.1 An additional medial portal is subsequently created in order to aid in reduction and screw placement. The medial portal is created in abduction and external rotation of the hip (i.e., the figure-4 position). The adductor tendon is identified, and the portal is then safely positioned posteriorly to its margin, approximately 4 to 5 cm distal to the inguinal fold, avoiding the saphenous vein (usually identified with an ultrasound scan). The fragment is mobilized, debrided, and then reduced with use of a microfracture awl or a large Kirschner wire (used as a joystick). Following reduction, temporary fixation is performed with use of long Kirschner wires under direct visualization and fluoroscopic guidance. If reduction is satisfactory, definitive fixation can be performed with use of 4.5-mm headless screws through the medial portal. All steps of fragment reduction and fixation are performed through the medial portal, with the patient in the figure-4 position. Once the screws are placed, a final dynamic arthroscopic and fluoroscopic check is performed. Alternatives: In Pipkin type-I fractures, surgery is recommended when the femoral head fragment is large (exceeding 15% to 20% of the femoral head volume) and displaced (by >3 mm). In such cases, if untreated, spontaneous evolution to osteoarthritis may occur. For fragments smaller than 10% to 15% of the femoral head volume, arthroscopic removal is often the best choice2. Several approaches (e.g., Smith-Petersen, modified Hueter, Kocher-Langenbeck, and surgical safe dislocation) have been proposed for reduction and fixation, with surgical safe dislocation being the most versatile because of the uniquely complete visualization of the femoral head3. Rationale: The arthroscopic reduction and fixation technique for a non-comminuted Pipkin type-I fracture holds the intrinsic advantages of being less invasive than open surgery in terms of surgical exposure, and having less blood loss, infection risks, and wound complications. Arthroscopy allows direct visualization of the fragment and its reduction surface, along with removal of articular loose bodies and debridement. The surgical time is influenced by the surgeon's experience, but often is no longer than with an open procedure. In the few studies assessing the use of this technique, the rates of osteonecrosis and heterotopic ossification are lower than with open techniques. It is worth noting that the studies assessing the use of this procedure are limited both in number and quality; however, the results of these studies have been excellent. It must also be noted that patients undergoing arthroscopic fixation are mostly selected for this treatment because they have less severe injuries2-12. Expected Outcomes: Open reduction and fixation through one of a variety of approaches is the gold standard treatment for Pipkin fractures; however, it is a relatively invasive procedure, prone to increased risks of osteonecrosis of the femoral head and heterotopic ossification (from 4% to 78% of cases). In some cases, arthroscopic reduction and fixation can be as effective as open reduction, and carries with it the intrinsic advantages of a keyhole procedure. The reported 4.6% global complication rate following arthroscopic fixation demonstrates the potential advantages of this technique, with limits due to the low numbers of treated cases4. Important Tips: The operating room should be carefully set up, especially regarding the positions of the C-arm and the arthroscopy tower, which should be double-checked before starting the procedure.The medial portal should be created after identification of the saphenous vein on an ultrasound scan. The anesthesiologist or a radiologist may mark the vein on the skin preoperatively, or the surgeon may extend the arthroscopic portal and perform a superficial dissection to avoid the vessel.Visualization after creation of the portals is usually suboptimal until the hematoma is completely removed. Patience must be maintained in this phase of the procedure.A microfracture awl or a large Kirschner wire can be utilized as a joystick to aid in reduction of the fragment, from either the usual portals or the medial portal. This aid can facilitate rotation of the fragment, which is a key step in the reduction phase.Definitive fixation can be achieved with use of 4.5-mm cannulated headless screws. Large cannulated headless screws have longer and larger Kirschner wires that can also aid in reduction when used as joysticks, reducing the risk of bending or breaking during screw insertion. Additionally, a 4.5-mm screwdriver is longer, allowing easier insertion, especially in patients with a larger thigh. The large diameter should not be a concern because the head is sunk in a non-weight-bearing area of the head.To avoid the risk of misplacement or loss of the screw during its insertion, make use of a cannulated guide handle for 4.5-mm screws, such as the guide utilized in a Latarjet arthroscopic procedure.To prevent screw loss into the joint, utilize a loop-knotted wire around the proximal part of the screw; this wire is cut at the end of the procedure.

Surgical Technique: Arthroscopic Reduction and Fixation of Partial Posterior Wall Acetabular Fractures.

Partial posterior wall fractures are usually fixed with open reduction-internal fixation through an open posterolateral approach, but when the fragment may be fixed without a plate (with screws only), reduction and fixation may also be achieved via hip arthroscopy with the patient in the prone position. This article presents all the surgical steps to perform this procedure.

The pie-crust surgical technique for medial collateral ligament release: enhancing visualization of the medial compartment in knee arthroscopy.

This study presents a comprehensive surgical technique for performing a 'pie-crust' release of the medial collateral ligament (MCL) to enhance visualization of the medial compartment during arthroscopic knee procedures. The primary objective of this research is to improve the precision of diagnosis and treatment for injuries specifically affecting the posterior horn and posterior root of the medial meniscus. Arthroscopic knee procedures have become increasingly common in orthopedic surgery, offering the advantage of minimally invasive techniques for treating a wide range of knee conditions. However, accessing and visualizing the posterior structures within the medial compartment can be challenging. To overcome this limitation, the surgical technique presented in this study offers a systematic approach that includes patient positioning, precise identification of anatomical landmarks, and a detailed, step-by-step procedural description. The process begins with meticulous marking of anatomical landmarks to provide reference points. Precisely identifying the location for the MCL release is of utmost importance. This involves making needle punctures with guidance from arthroscopic visualization and applying valgus strain to the knee as necessary. One of the key advantages of this described surgical technique is its focus on safety and efficacy. Surgeons can work more confidently and precisely by reducing the risk of iatrogenic cartilage damage and facilitating access to the posterior structures within the medial compartment. Clinical outcomes from this approach have demonstrated consistently favorable results, leading to improved patient recovery and reduced complications. Furthermore, it is noteworthy that the postoperative use of a brace is not mandatory, adding to the appeal of this technique for both patients and surgeons. This surgical technique's enhanced visualization and optimized treatment outcomes make it a valuable tool in the arsenal of orthopedic surgeons specializing in knee arthroscopy. In conclusion, this study's surgical technique has the potential to significantly improve the diagnosis and treatment of patients with meniscal injuries in the medial compartment, ultimately leading to better clinical outcomes and patient satisfaction.

Ganz femoral head reduction associated with coverage and containment procedures improve radiological and functional outcomes in Perthes' disease.

Aims: Ganz's studies made it possible to address joint deformities on both the femoral and acetabular side brought about by Perthes' disease. Femoral head reduction osteotomy (FHRO) was developed to improve joint congruency, along with periacetabular osteotomy (PAO), which may enhance coverage and containment. The purpose of this study is to show the clinical and morphological outcomes of the technique and the use of an implemented planning approach. Methods: From September 2015 to December 2021, 13 FHROs were performed on 11 patients for Perthes' disease in two centres. Of these, 11 hips had an associated PAO. A specific CT- and MRI-based protocol for virtual simulation of the corrections was developed. Outcomes were assessed with radiological parameters (sphericity index, extrusion index, integrity of the Shenton's line, lateral centre-edge angle (LCEA), Tönnis angle), and clinical parameters (range of motion, visual analogue scale (VAS) for pain, Merle d'Aubigné-Postel score, modified Harris Hip Score (mHHS), and EuroQol five-dimension five-level health questionnaire (EQ-5D-5L)). Early and late complications were reported. Results: The mean follow-up was 39.7 months (standard deviation (SD) 26.4). The mean age at surgery was 11.4 years (SD 1.6). No major complications were recorded. One patient required a total hip arthroplasty. Mean femoral head sphericity increased from 46.8% (SD 9.34%) to 70.2% (SD 15.44; p < 0.001); mean LCEA from 19.2° (SD 9.03°) to 44° (SD 10.27°; p < 0.001); mean extrusion index from 37.8 (SD 8.70) to 7.5 (SD 9.28; p < 0.001); and mean Tönnis angle from 16.5° (SD 12.35°) to 4.8° (SD 4.05°; p = 0.100). The mean VAS improved from 3.55 (SD 3.05) to 1.22 (1.72; p = 0.06); mean Merle d'Aubigné-Postel score from 14.55 (SD 1.74) to 16 (SD 1.6; p = 0.01); and mean mHHS from 60.6 (SD 18.06) to 81 (SD 6.63; p = 0.021). The EQ-5D-5L also showed significant improvements. Conclusion: FHRO associated with periacetabular procedures is a safe technique that showed improved functional, clinical, and morphological outcomes in Perthes' disease. The newly introduced simulation and planning algorithm may help to further refine the technique.

Bi-cruciate retaining total knee arthroplasty is here to stay: A consecutive series transitioning from manual instrumentation to enabling technologies.

BACKGROUND: Bicruciate-retaining (BCR) total knee arthroplasty (TKA) has seen renewed interest due to the potential for more natural knee kinematics with anterior cruciate ligament (ACL) retention. OBJECTIVE: The present study attempts to determine differences in the 2-year survivorship and patient-reported outcomes between two surgical strategies (traditional instrumentation versus robotics) applied to the extensive use of a modern, 2nd generation BCR TKA design. METHODS: We performed a retrospective study with prospectively collected data of 113 patients who underwent primary TKA between 2018 and 2020 using a 2nd generation BCR TKA implant. Patient demographics, PROMS, and intra/post-operative complications were collected. Patients were also evaluated according to the use or not of robotics. A Kaplan-Meier analysis was used to evaluate revision-free survival at follow up. RESULTS: 102 patients were enrolled: 90 received traditional surgery and 12 robotic-assisted surgery. The mean age was 68 years (SD 7.76) with an average BMI of 29.6 kg/m2 (SD 3.56). The mean follow up (FU) was 32.4 ± 6.2 months (range 24-45 months). Survivorship at 2 years was 98% (95% CI: 92.4-99.5). Revisions/reoperations were performed for anterior cruciate ligament (ACL) tear (1/4), pain (1/4), arthrofibrosis (1/4) and acute periprosthetic joint infection (PJI) (1/4). At final FU, 92 patients (90.2%) considered themselves satisfied, showing a mean OKS of 40.6 (SD 5.1) and a mean FKS of 76.7 (SD 11.8). No differences in the outcome were found between traditional and robotic-assisted procedures. CONCLUSION: The modern BCR design evaluated in this study achieved excellent results in terms of implant survivorship, low rate of reoperation and clinical results, independently from the use of enabling technologies.

Two-stage total joint replacement for hip or knee septic arthritis: post-traumatic etiology and difficult-to-treat infections predict poor outcomes.

PURPOSE: Septic arthritis (SA) is a rare but significant clinical challenge in orthopedics that can impact patients' quality of life. This study aims to examine the clinical outcomes of patients undergoing two-stage total joint replacement (TJR) in hip and knee SA and analyze potential predictors of treatment failure. METHODS: A retrospective analysis was conducted using data from a prospectively collected institutional arthroplasty registry from January 1st, 2012, to January 1st, 2019. Patients with hip or knee SA who underwent a two-stage TJR and had at least two years of follow-up were included. Demographic characteristics, surgical variables, and outcomes were collected and analyzed from clinical and surgical data. Statistical analysis was performed using IBM SPSS Statistics, with statistical significance at p < 0.05. RESULTS: One hundred and fourteen patients (61 with hip SA, 53 with knee SA) were included in the study. The mean follow-up was 72.8 months. Postoperatively, both clinical and functional outcomes significantly improved, as indicated by the Hip Society Score (HHS) and Knee Society Score (KSS). The overall success rate of the two-stage protocol was 89.5%. Complications that did not require revision occurred in 21% of cases. The most identified pathogen was methicillin-sensitive Staphylococcus aureus (MSSA). Difficult-to-treat (DTT) infections and post-traumatic etiology were identified as predictors of treatment failure in patients undergoing two-stage TJR for hip and knee SA. CONCLUSIONS: Two-stage TJR in hip and knee SA demonstrated favorable clinical outcomes at mid-term follow-up. The procedure significantly improved functional scores and achieved a high success rate, while DTT infections and post-traumatic etiology were associated with a higher risk of treatment failure.

Endoscopic Assisted Percutaneous Fixation of Anterior Inferior Iliac Spine Avulsion Fracture, Surgical Technique.

Avulsion fractures of the anterior inferior iliac spine rarely occur in adolescent athletes during rectus femoris contractions or eccentric muscle lengthening while the growth plate is still open. Currently, there are no official guidelines in the literature on the treatment indications of this type of fracture or the type of surgical technique to be used. Nowadays, young and athletic patients desire a quick return to their previous activities, which makes surgical treatment a reasonable choice. Open reduction and internal fixation with an anterior approach are usually recommended when the avulsion fragment has more than 1.5-2 cm displacement on plain radiographs. However, ORIF is associated with a higher risk of heterotopic ossifications and increases the risk of damage to the LFCN. An endoscopic technique was designed to reduce these complications. This technical note describes a procedure of percutaneous fixation to AIIS through 3 endoscopic portals that could potentially minimize complications associated with an open surgical dissection, allowing anatomic reduction under direct visualization.

Proximal femoral valgus osteotomy for the treatment of developmental coxa vara: a systematic review of the literature.

Background: Developmental Coxa Vara (DCV) consists on a pathological reduction in head-shaft angle (HSA) and increased femoral retroversion. Several case series reported outcomes on proximal femoral valgus osteotomy (PFVO), but no evidence synthesis had been conducted. This systematic review aimed to (1) analyze success rate and complications, (2) report the degree of correction according to the HSA and the Hilgenreiner Epiphyseal Angle (HEA), compare success rate and degree of correction of subtrochanteric (SVO) vs intertrochanteric (IVO) osteotomy, and (4) difference in success rate and correction between patients in which an internal (IF) or external fixation (EF) technique was used. Methods: Four databases (PubMed, Scopus, Embase, and Cochrane Database of Systematic Reviews) were searched until February 20th, 2024 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies presenting outcomes on PFVO for DCV with >2 years follow-up and >5 patients were included. Review articles, language other than English and coxa vara secondary to other conditions were excluded. Study quality was evaluated through MINORS criteria. Results: 10 case series (level of evidence IV) were located for a total of 153 patients and 192 hips. Baseline results were as follows: male/female ratio was 1.45, mean age at surgery was 6.7 ± 1.5 and follow-up 5.1 ± 5.5 years. Overall success rate was 88.8%, with failure considered as any indication to revision surgery. Complications included loss of correction (10.9%), deep (1.0%) or superficial wound infection (2.6%). Revision surgery was performed in 18 hips (9.4%). Average correction was measured through HSA (preoperative 94.6 ± 8.1, postoperative 134.4 ± 10.2, change 38.2 ± 7.5°, p < 0.001) and HEA (preoperative 71.9 ± 5.5, postoperative 31.7 ± 5.7°, change 33.7 ± 10.5°, p < 0.001). Success rate was similar between osteotomy techniques (SVO: 91.0%; IVO: 94.1%; p = 0.48) and fixation strategy (IF: 85.4%; EF 95.8%; p = 0.096). Conclusions: PFVO presented satisfactory results for the treatment of DCV, with similar outcomes concerning the osteotomy site and fixation technique used. HSA and HEA correction were correlated to PFVO success rate. However, coxa vara is a tridimensional deformity, thus other parameters such as posterior sloping angle, mechanical axial deviation and proximal femoral offset should be included in future studies.

No significant clinical differences between native or reduced posterior tibial slope in kinematically aligned total knee replacement with posterior cruciate-retaining.

Aims & objectives: Total knee arthroplasty (TKA) is a common surgical procedure for end-stage knee osteoarthritis. However, conventional alignment techniques may lead to postoperative dissatisfaction in up to 20% of cases. Kinematic alignment (KA) has emerged as a new philosophy to restore the native joint line and achieve more natural kinematics. Preserving the posterior tibial slope (PTS) and posterior cruciate ligament (PCL) is crucial to maintaining the pre-arthritic joint line and improving knee kinematics. This study aimed to assess the prevalence of postoperative PTS changes and their impact on functional outcomes and range of motion. Materials & methods: A retrospective single-center study was conducted on patients who underwent KA-TKA with PCL preservation. The preoperative and postoperative PTS were measured on lateral knee radiographs using the tibial proximal anatomic axis method. Patient-reported outcome measures (PROMs) were collected pre- and postoperatively up to a two-year follow-up. Results: Of the 95 included patients, 62.1% achieved an anatomically similar PTS (within 3° from the preoperative value), while 37.9% experienced noticeable PTS changes. However, no significant associations existed between PTS changes and compromised PROMs (WOMAC, 22.2 and 23.1; FJS, 66.6 and 67.3), ROM (118.5° and 119.4°), or patient satisfaction. No postoperative complications requiring reoperation or component revisions were observed. Conclusion: Preserving or modifying the native PTS during KA-TKA could be confidently undertaken without compromising functional outcomes or patient satisfaction.

Combining an Anterolateral Complex Procedure With Anterior Cruciate Ligament Reconstruction Reduces the Graft Reinjury Rate and Improves Clinical Outcomes: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction (ACLR) is a well-established surgical procedure, but it may not always restore complete rotational knee stability. Interest is increasing in anterolateral complex (ALC) procedures, lateral extra-articular tenodesis (LET) and anterolateral ligament reconstruction (ALLR), in association with ACLR to overcome this problem. The better ALC procedure, LET or ALLR, remains controversial to date. PURPOSE: To analyze the patient-reported outcome measures and ACL reinjury rate after ACLR with an ALC procedure compared with after isolated ACLR, as well as to analyze the clinical results and graft failure rate of the LET group versus the ALLR group. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 2. METHODS: A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flowchart was used to conduct a comprehensive search of 5 databases: Scopus, MEDLINE, Embase, PubMed, and the Cochrane Database of Systematic Reviews. Only randomized controlled trials were included. Eligible articles were classified according to the levels of evidence of the Oxford Centre for Evidence-Based Medicine. A methodological quality assessment of randomized controlled trials was performed using the Risk of Bias 2 tool. The present systematic review and meta-analysis was registered on PROSPERO. RESULTS: A total of 14 clinical trials were included in the final analysis, with 1830 patients. Isolated ACLR or a combined procedure with LET or ALLR was performed, with several characteristics described, including the surgical technique, additional torn knee structures and their management, graft failure, complications, clinical outcomes, clinical and instrumental examinations to assess knee stability, and postoperative protocols. Regarding clinical outcomes, pivot-shift tests and reduced graft failure, a significant difference was found in the superiority of the combined ACLR associated with the ALC procedure compared with an isolated ACLR (P < .05). No statistically significant difference was found between the 2 ALC procedures. CONCLUSION: This systematic review and meta-analysis reported on the importance of combined ACLR and ALC procedures in patients with a high-grade rotational laxity, as both procedures, LET or ALLR, without superiority of one over the other, are associated with improved pivot-shift tests, patient-reported outcome measures, and reduced graft failure rates.

Indications, complications, and clinical outcomes of fixation and acute total hip arthroplasty for the treatment of acetabular fractures: A systematic review.

PURPOSE: Acetabular fracture fixation can be challenging, especially in the elderly. Open reduction and internal fixation (ORIF) alone may not allow for early weight bearing and is associated with a high rate of secondary osteoarthritis; therefore, a combined hip procedure (CHP) or ORIF with acute total hip arthroplasty, may be beneficial in this population. The objective of this study was to perform a systematic review of all reported cases of CHP. METHODS: PubMed, Embase, Scopus, and Cochrane databases were searched for studies analyzing acetabular fractures in the elderly managed with a combined hip procedure (CHP). The research was performed following the PRISMA guidelines. The included studies' methodological quality was evaluated using the MINORS score. The present study was registered on PROSPERO. RESULTS: Eleven clinical studies were included in the final analysis. The mean age was 74.4 (63.2-78) years. Low-energy trauma was the most common mechanism of injury (64%). The most prevalent fracture pattern was the anterior column and posterior hemitransverse (ACPHT) (30.6%). The Kocher-Langenbeck approach was preferred for ORIF of posterior fractures and hip arthroplasty. The ilioinguinal approach and modified Stoppa were generally used for anterior fractures. The overall complication rate was 12.2%, and hip dislocation was the most frequent cause of reoperation (4.4%). The average Harris Hip Score reported postoperatively was 81.6 points, which was considered "good." CONCLUSIONS: CHP is a safe treatment for elderly acetabular fractures with an acceptable complication and reoperation rate that results in good clinical outcomes. LEVEL OF EVIDENCE: Level of evidence IV.

Surgical treatment of popliteomeniscal fascicles tears is associated with better patient-reported outcome measures. A systematic review and meta-analysis.

PURPOSE: Popliteomeniscal fascicles (PMFs) are a component of the popliteal hiatus complex in the knee, and their injury primarily affects young athletes participating in sports activities involving twisting movements. The identification of PMFs tears presents a challenge, often accompanied by lateral pain and a locking sensation. The objective of this systematic review (SR) and meta-analysis is to enhance the suspicion and recognition of PMFs tears, aiming to facilitate the treatment of this condition, particularly in symptomatic young patients. METHODS: A comprehensive search, focused on studies examining PMFs injuries and their treatment, was conducted in four databases, PubMed, Scopus, Embase, and Web of Science. The ROBINS-I tool was used to evaluate the risks of bias. The PRISMA flow diagram was used to conduct the research and select the included studies. A meta-analysis was conducted for the Lysholm score, the Tegner Activity Scale, and the subjective IKDC score. The present SR and meta-analysis was registered on PROSPERO. RESULTS: Five clinical studies were included in the final analysis, comprising 96 patients. All the patients underwent a preoperative MRI assessment and a diagnostic arthroscopy to detect the PMFs tears, with a subsequent surgical procedure either open or arthroscopically performed. Surgery was associated with the resolution of symptoms. A statistically significant improvement in the Lysholm score (p: 0.0005) and the subjective IKDC score (p: 0.003) after the surgical procedure with respect to the preoperative evaluation was found. CONCLUSION: This SR and meta-analysis showed a significant improvement in the Lysholm score and subjective IKDC score following surgery for PMFs tears. However, controversy persists regarding the optimal surgical approach, with current literature favoring arthroscopic procedures. LEVEL OF EVIDENCE: IV.
