Jorge","doi":"10.1177/26350254231204638","DOIUrl":"https://doi.org/10.1177/26350254231204638","url":null,"abstract":"Background: The quadruple graft from the hamstring tendons has become a widely used option in the reconstruction of the anterior cruciate ligament (ACL), however, this graft may not have the desirable diameter for the reconstruction, increasing the risk of re-rupture. In this context, the peroneus longus tendon graft appears as an option to complement other grafts, transforming a thin quadruple graft into a sextuple graft. Indications: The sextuple graft technique for ACL reconstruction is used in patients who have a quadruple graft with a diameter of less than 8 mm, and due to its length, it is not possible to make a quintuple graft, for example. Technique Description: Initially, the hamstring tendons are removed with the aid of a tenotome. After that, the anterior half of the peroneus longus tendon is identified and removed. On the back table, the definitive graft is prepared so that we have a sextuple graft with a diameter greater than 8 mm. Finally, the ACL reconstruction is performed anatomically using an adjustable loop device in the femur and an interference screw in the tibia. Results: In our experience with patients who have a hamstring graft diameter of less than 8 mm, we obtained an average increase of 1.8 mm in graft diameter when augmentation was performed with the anterior half of the peroneus longus. Discussion: Grafts less than 8 mm in diameter are at increased risk of rupturing and failure of surgical treatment of the ACL injury. The surgeon must be prepared to make a quintuple or sextuple graft, but in some patients, the tendons are short or there is no availability of a tissue bank, making this practice impossible. The use of the anterior half of the peroneus longus to perform graft augmentation is safe, causing almost no morbidity to the donor area and is easily accessible during the procedure, making it an excellent option for increasing the diameter of thin grafts.

It can affect any joint, tendon, or bursa, withal those around the knee. The intra-articular lesion is more prevalent and is more frequently diagnosed in female children or young adults. Indications: Surgery is indicated when patients present with recurrent painful hemarthrosis that affect daily living and functionality. Technique Description: Diagnostic knee arthroscopy, initially without tourniquet inflation, was performed to detect and study the extent of the lesion. Afterwards, the tourniquet was inflated to proceed with the surgical excision. Medial parapatellar approach was performed, and limits of the hemangioma were identified. Wide resection was performed taking care to not damage the medial meniscus and medial condyle cartilage. Neoplastic lesion was sent to pathology analysis. The tourniquet was deflated and hemostasis checked because these lesions can present extensive bleeding. Results: Localized, well-circumscribed, and encapsulated lesions have been reported to usually present low recurrence rate when completely excised. Discussion/Conclusion: It is a rare disease, and around 200 cases have been reported; therefore, conclusions about treatment and outcomes rely mostly on case series and case reports. Early diagnosis and treatment are paramount to prevent degenerative changes secondary to recurrent hemarthrosis.

Indications: For ACL reconstruction, point C can be used as an arthroscopic intraoperative parameter to define the position of the femoral tunnel on the distal proximal and anteroposterior axes. Technique Description: For access to the joint, standard arthroscopic ports, both anterolateral (AL) and anteromedial (AM), are used. By directing the camera toward the posterior region of the lateral femoral condyle through the AM port, it is possible to visualize the end of the posterior and proximal articular cartilage, the so-called C point. In this case, we sought to position the center of the femoral tunnel in the center of the AM band of the ACL. Holding the camera through the AM portal and visualizing point C, a millimeter-scale femoral guide is introduced through the AL portal toward the posterior femoral cartilage (point C) and positioned over it, creating a line between point C and the lateral distal femoral cartilage. The distance between point C and the distal femoral cartilage is measured. At this time, an accessory AM portal 1.5 cm from the AM port is constructed. Through it, with the aid of an ice pick or radiofrequency tip, a marking is made in the deep to shallow axis at 35% of this distance. Then, approximately 2 mm above the imaginary line formed by the union of point C and the lateral distal femoral cartilage, the center of the femoral tunnel is marked. Results: Point C is an anatomical landmark that is easy to view and is present in all knees; thus, it can be used as a reference during surgery for positioning the femoral tunnel. Discussion/Conclusion: Point C can be used as an arthroscopic intraoperative parameter to define the position of the femoral tunnel in ACL reconstruction.

Indications: Symptomatic patellofemoral instability with maltracking, particularly in cases with a tibial tuberosity-trochlear groove distance >16 mm. Technique Description: We describe an oblique osteotomy from medial to lateral. A careful completion of the osteotomy is made with an osteotome, and the resulting fragment is mobilized to achieve anteromedial repositioning—as well as distalization in cases of patella alta. Two bicortical screws with a washer are used for fixation of the tibial tubercle following anteromedialization. Results: Systematic reviews demonstrated that the treatment of the lateral patellar instability requires an individual treatment and the anteromedial TTO is a very important procedure alone or in association with medial patellofemoral ligament.

Lee","doi":"10.1177/26350254231184906","DOIUrl":"https://doi.org/10.1177/26350254231184906","url":null,"abstract":"Background: In patients with multiligament knee injuries, anterior cruciate ligament (ACL) tears are often reconstructed. Recent studies have shown good results when the ACL tibial avulsions are repaired. The advantages of ACL tibial avulsion repair are the preservation of the native anatomy, reduction in donor site morbidity, and lower risk of tunnel convergence. Indications & Technique Description: We show 2 techniques for repairing ACL tibial avulsion fractures. The first case describes the use of hybrid fixation (screw and suture), with staged repair and reconstruction in a patient with high-energy knee fracture-dislocation. The second case describes the use of suture ACL repair via tunnels in a patient with a low-energy knee dislocation and an ACL tibial avulsion fracture. When repairing ACL tibial avulsion fractures, screw fixation is recommended for larger tibial fragments. In smaller comminuted fragments, tying sutures passed through the ACL via tibial tunnels may be more appropriate. Results: Several studies have demonstrated good postoperative results in patients following the fixation of ACL tibial avulsion fractures. Both screw and suture fixation are effective methods of repairing ACL tibial avulsion fractures and have similar postoperative outcomes. It has been found that screw fixation is associated with a higher risk of subsequent surgery and implant removal than suture fixation. Conclusion: The repair of ACL tibial avulsion fractures in multiligament knee injuries is an alternative to ACL reconstruction that demonstrates excellent postoperative patient outcomes, good patient satisfaction, and good return to sports.

Combined hip arthroscopy with femoral derotational osteotomy (FDRO) has been shown to successfully treat those with intra-articular hip pathology with excessive anteversion or retroversion of the femur. Indications: We describe the technique for combined hip arthroscopy and FDRO in patients with symptomatic intra-articular hip pathology in the setting of excessive anteversion or retroversion of the femur. Technique Description: Hip arthroscopy is performed using standard anterolateral, modified mid-anterior, and distal anterolateral accessory portals. The labrum is repaired using a narrow diameter suture. Femoroplasty is performed with utilization of fluoroscopic imaging to assess resection. Dynamic flexion is performed as a final check of adequacy of resection. Capsular closure is performed in all cases. After hip arthroscopy, the patient is repositioned on a radiolucent table. A piriformis start point is obtained with a guide pin followed by standard opening reaming and ball-tipped guidewire placement. A femoral osteotomy is made just proximal to the isthmus and made through a lateral approach to the femur. Two K-wires are placed distal and proximal to the osteotomy site. A goniometer is then used to measure rotation. A drill is used to perforate the cortex circumferentially at the osteotomy site. After standard reaming, a sagittal saw is then used to start the osteotomy cut followed by an osteotome. An intramedullary nail is inserted over a ball-tipped guidewire while rotational reduction is assessed from the foot of the operating table. Distal interlocking screws are placed, and the nail is backslapped to create compression at the osteotomy site prior to placing proximal interlocking screws. Results: Recent studies show improved hip outcome scores in patients who undergo concomitant hip arthroscopy and FDRO for symptomatic abnormal femoral version. Discussion/Conclusion: Identifying patients who would benefit from concomitant surgeries requires thorough preoperative evaluation. Correct identification and treatment of these patients leads to improved outcomes.

Various reconstruction techniques have been described using different grafts and fixation methods; however, there is a paucity of reported outcomes and there is no consensus on standard of care. Indications: The patient is a 36-year-old man who presented with a failed patellar tendon reconstruction 14 months after his initial surgery (performed 1 year after the initial injury) with functional weakness and loss of extension. The patient was indicated for a revision patellar tendon reconstruction due to persistent functional limitations. Technique Description: The revision patellar tendon reconstruction was performed with gracilis and semitendinosus tendon autografts harvested from the ipsilateral limb. Hardware was removed from the initial graft tunnels in the tibial tubercle and patella. Patellar height was estimated using fluoroscopic measurement of the contralateral patellar tendon length. The graft is first passed through the patellar tunnel, and the individual limbs of the graft are then both placed through the tibial tubercle tunnel. A sternal wire in a figure-of-eight configuration was used to progressively distalize the patella to match the native patellar height, and the graft was then tensioned and secured together. Results: The patient regained full range of motion at 2-year follow-up and was able to return to work and activities without functional limitations. Recent case series also using ipsilateral hamstring tendon autograft for chronic patellar tendon reconstruction report improved patient outcome scores, normal Insall-Salvati index, improved quadriceps strength, and high levels of patient satisfaction. Discussion/Conclusion: Chronic patellar tendon ruptures are technically challenging to treat, especially in the context of revision of a failed reconstruction. The technique presented in this video may aid orthopaedic surgeons in treating this rare but debilitating injury. Given the lack of high-quality evidence, future studies are needed to explore graft choices, graft fixation techniques, and postoperative protocols.

Efficient bone-patellar tendon-bone (BTB) allograft preparation is beneficial to reduce operating time and ensure optimal reconstruction with bony fixation. Indications: ACL reconstruction with BTB allograft is indicated for skeletally mature and older patients, patients who are less active and have fewer physical demands, patients who have had previously harvested autograft, circumstances where an autograft harvest is inadequate, patients with multiligament knee injuries, and patients who prefer allograft use. Technique Description: The central third of the BTB allograft is harvested, aiming for a graft diameter of 10 mm along the tendon. The tibial bone plug is first cut to a length of 25 to 30 mm and width of 10 mm with the saw at a 70° angle to the bone. The patellar bone plug is cut to a length of 25 mm and width of 10 mm with the saw at a 45° angle to the bone. The bone plugs are mobilized, and soft tissue is dissected to free the graft. The graft is trimmed until it fits through a 10-mm sizer on each side. A single hole is created with a k-wire in the patellar bone plug, and a #5 Ethibond suture is passed. On the tibial bone plug, 2 holes are made perpendicular to one another, and a #2 Fiberwire suture is passed through each of these holes. These sutures allow for facilitated graft passage and tensioning. Once the graft is affixed with interference screws, the graft is arthroscopically evaluated throughout range of motion. Results: ACL reconstruction with BTB allograft provides high success rates in appropriately selected patients. Data demonstrate more optimal mechanical properties by harvesting the central third of the allograft tendon in younger donors. Non-irradiated and less chemically processed grafts are also preferred to optimize biomechanical properties. Discussion/Conclusion: Bone-patellar tendon-bone allograft with 2 bone plugs offers a reliable alternative to other allografts or autografts. Preparing the allograft in a fashion similar to an autograft harvest may increase familiarity with techniques and facilitate surgical efficiency and graft passage.

Nho","doi":"10.1177/26350254231159422","DOIUrl":"https://doi.org/10.1177/26350254231159422","url":null,"abstract":"Background: The learning curve for the surgical treatment of cam deformities in femoroacetabular impingement syndrome (FAIS) presents a challenge for young or inexperienced surgeons, with the leading cause of failed hip arthroscopy being incomplete resection. Historically, alpha angle measurements are typically used perioperatively to both diagnose cam deformity and evaluate the adequacy of cam resection. The computer-assisted Styker HipCheck system offers the surgeon real-time alpha angle measurements, assisting with the execution of cam resection. Indications: The indication for use is any hip arthroscopic procedure for femoroacetabular impingement requiring osteochondroplasty of cam deformity. Advantages of the HipCheck system include shortened operative time; reduced risk of inadequate or over-resection; accelerated learning curve; no requirement of preoperative computed tomographic imaging or pre-planning; being noninvasive, portable, and not requiring additional instruments; increased patient and surgeon satisfaction; and allowance of repeated quantitative and visual assessment, which is particularly beneficial for more difficult regions, such as posteromedial and posterolateral, to view the femoral head/neck. Technique Description: Briefly, after intra-articular procedures are complete, the peripheral compartment is accessed. We prefer a T-type capsulotomy. Next, the cam deformity is registered on Stryker HipCheck software, automatically calculating alpha angles as the hip is dynamically moved through 6 registered positions. A standard cam resection is then performed. Once complete, the hip is dynamically assessed and again registered with the HipCheck system in the same 6 positions to ensure adequate resection has been performed. Results: When comparing patients with FAIS undergoing computer-guided resection or standard resection, both surgical interventions demonstrated successful reduction in alpha angle and no difference in degree of resection. In addition, the various computer-guided views exhibited good correlations to clinical radiographs. Discussion: The HipCheck intraoperative system allows the surgeon to evaluate the adequacy of cam resection through the use of automated alpha angles. Furthermore, the system offers instantaneous feedback of cam resection at any desired position of the hip. This intraoperative technology may offer less experienced surgeons an aid when performing hip arthroscopy for cam resection in the setting of femoroacetabular impingement.
