A Medial Meniscal Root Pullout Repair With the Use of a Tibial Tunnel Suturing Technique
No full textA meniscal root tear is one of the common knee injuries that can lead to degenerative changes in the knee joint. Meniscal root repairs can restore proper biomechanics of the knee joint. We have developed a suturing technique that uses a tibial tunnel for a pullout suture medial meniscal root repair. This is a straightforward technique that helps to promote simple suturing of the medial meniscal root, avoid iatrogenic injuries to the articular cartilage, and produce an additional working portal during a meniscal root repair
Both Posterior Root Lateral-Medial Meniscus Tears With Anterior Cruciate Ligament Rupture: The Step-by-Step Systematic Arthroscopic Repair Technique
No full textThe occurrence of posterior root tear of both the lateral and medial menisci, combined with anterior cruciate ligament rupture, is rare. Problems may be encountered such as the difficulty to access the medial meniscal root tear, the confusing circumstances about which structure to repair first, and the possibility of the tunnel for each repair to become taut inside the tibial bone. We present the arthroscopy technique step by step to overcome the difficulties in an efficient and time-preserving manner
Arthroscopic All-Inside Medial Meniscus Extrusion Reduction
No full textMedial meniscus extrusion is commonly seen in patients who have medial meniscus posterior root tear. Extruded meniscus results in faster progression of knee arthrosis. Thus, it is important to reduce the extrusion as well as treat the cause of extrusion. This Technical Note describes an all-inside arthroscopic technique to reduce the meniscus extrusion. An additional medial portal has to be made along with the standard anteromedial and anterolateral portals. A double-loaded suture anchor is used to secure the extrusion of the meniscus in its native position. Thus, making a transosseous tibial tunnel is not required. It is easy to perform and is an efficient technique
Single Portal Subscapular Repair by a Cross Shuttle Loop Technique
No full textWith the rise in subscapular tendon tears, most of them being partial that eventually end up in complete tears, we present our experience in the management of such tears using a cross shuttle loop technique. This technique incorporates the advantages of a single portal for anchor placement and repair, easy to use cross loops in limited working space, and familiar viewing
Posterior Horn of Medial Meniscal Peripheral Capsular Lesion: The Arthroscopic Repair Technique Working in the Posterior Compartment
No full textA posterior horn of medial meniscal peripheral capsular is usually associated with the anterior cruciate ligament injury. The conventional repair technique with the camera in the anterolateral portal cannot precisely restore the slope capsular synovium to the original attachment point. We present the arthroscopic technique for improving the accuracy and quality of the repair by working in the posterior compartment. When the posterolateral portal is used as the viewing portal, the accuracy of repair is improved because we can assess the full extent of the lesion and lift the sagging peripheral tissue to the more central part
Osteochondritis Dissecans of the Knee: Arthroscopic Suture Anchor Fixation
No full textOsteochondritis dissecans (OCD) is a subchondral bone abnormality, in which subchondral bone and the overlying articular cartilage detach from the bony bed. Multiple techniques for OCD fixation have been described, including metallic, bioabsorbable implants and biological fixation. We describe a surgical technique for OCD lesions including bony bed preparation with curettage and microfracture, anatomic reduction, and fixation using a suture anchor to provide stability and healing of the lesion
A Surgical Technique for Posterolateral Placement of Interference Screw Accurately in Tibial Tunnel in Single-Bundle Anterior Cruciate Ligament Reconstruction
No full textAnatomic orientation of the graft in anatomic anterior cruciate ligament reconstruction is the key to improved knee stability, restoration of normal knee kinematics, and the prevention of long-term joint degeneration. The graft position and orientation in the joint depend on the position of the tibial and femoral tunnels. Graft displacement in the tibial tunnel due to the position of the interference screw when the screw has proximal fixation also has an effect on the orientation of the graft. We have developed a technique for adjusting guidewire placement for the interference screw posterolaterally in the tibial tunnel in anatomic single-bundle anterior cruciate ligament reconstruction. This technique helps to push the graft medially and anteriorly in the tibial tunnel, avoids impingement of the graft with the lateral femoral condyle, and helps to maintain the orientation of the graft in a more anatomic way
Arthroscopic Treatment of Popliteal Cyst: A Direct Posterior Portal by Inside-Out Technique for Intracystic Debridement
No full textPopliteal cysts are characterized by enlargement of the gastrocnemius-semimembranosus bursa. The pathogenesis includes a valvular opening between the knee joint and the bursa, and associated intra-articular pathology may give rise to knee effusion. The mainstay of treatment is conservative. If popliteal cysts are symptomatic, analgesia, aspiration, and steroid injection therapy may be considered, but most recur rapidly. In the past, open excision was an option if they remained symptomatic, but the associated recurrence rate was high. One important reason was that the intra-articular pathology causing the knee effusion was not treated. We present an alternative minimally invasive arthroscopic treatment using dye (methylene blue) directly injected into the cyst, which will leak from the cyst into the joint, to identify the valvular opening. The thickened valve is opened using a basket forceps and then enlarged using a motorized shaver to disrupt the 1-way mechanism between the joint and bursa, as well as to establish an unobstructed freeway connection between them. We also present a safe technique to create a direct posterior portal. Intracystic debridement of the fibrous membrane, nodules, and septa through this portal will decrease the recurrence rate of the popliteal cyst
Surgical Technique for Arthroscopy-Assisted Anatomical Reconstruction of Acromioclavicular and Coracoclavicular Ligaments Using Autologous Hamstring Graft in Chronic Acromioclavicular Joint Dislocations
No full textInjuries to the acromioclavicular (AC) joint are becoming common with contact sports and bike accidents. It is well known that in AC dislocations, the first structure to fail is the AC capsule followed by the trapezoid and conoid ligaments. The function of these ligaments must be restored to restore the anatomy and physiology of the AC joint to get the best results. Until now, no technique has emerged as the gold standard for restoration of the AC joint anatomy and function. In our technique, the stress is on recreating the anatomy to make it more individualized based on individual variations. This Technical Note describes a procedure to reconstruct the coracoclavicular ligaments and AC joint by an arthroscopy-assisted technique. Arthroscopy helps to diagnose additional intra-articular pathologies that can be treated simultaneously, and better preparation of the undersurface of the coracoid helps in bone-to-graft healing. Our approach is more individualized as clavicle tunneling is done according to the size of the coracoid base instead of a fixed distance. Vertical stability is provided by coracoclavicular ligament reconstruction, horizontal stability is provided by AC ligament reconstruction, and the articular disc is recreated by soft-tissue graft interposition, thus restoring the complete anatomy
The Supine Position for Shoulder Arthroscopy
No full textShoulder arthroscopy is traditionally performed with the patient in either the beach chair position or the lateral decubitus position. Each position has its advantages and disadvantages. The main topics for consideration include ease of surgery, view into the surgical field, risks to the patient, and economics of the setup. In the lateral decubitus position, it is inconvenient to work through the anterior portal and it is difficult to convert to an open procedure. In the beach chair position, it is difficult to manage the airway and cerebral oxygenation and the patient's head and the beach chair frame obstruct the insertion of a scope into the superior and posterior portals. This technical note presents the supine position for shoulder arthroscopic surgery. The supine position does not have the disadvantages of the traditional positions. In addition, it is comparatively easy to set up and comfortable for the patient
