Patellofemoral ankylosis: case report and technical note.

Introduction: It is our understanding that there is no consensual solution for the treatment of post-traumatic patellar ankylosis; therefore, the purpose of this work is to present two cases of patellofemoral retinacular interposition arthroplasty, and its corresponding technical note. CASE 1: Female, 24, patellar ankylosis secondary to supratranscondylar fracture, associated with comminuted diaphyseal tibia fracture. CASE 2: Female, 48, patellar ankylosis secondary to femoral diaphysis and lateral femoral condyle fracture.

Simultaneous Bilateral Knee Varus Stress Radiographic Technique.

Varus stress radiographs are reported as an effective and cost-beneficial diagnostic and decision-making tool for lateral knee injuries, both in the acute and chronic settings. The opening of the lateral compartment is reported to vary according to the number of structures injured, helping to differentiate isolated fibular collateral ligament injury from grade-III posterolateral corner injury. The conventional technique requires the physician or another healthcare provider to apply manual varus stress while obtaining the radiograph on one knee at a time.

Meniscus Repair in Children and Adolescents: A Systematic Review of Treatment Approaches, Meniscal Healing, and Outcomes.

Although the consequences of traumatic meniscus tears and the importance of meniscal repair are well-established in adults, the same cannot be said for the young population. Better evidence regarding the outcomes following traumatic meniscal tears in children would improve our understanding of this increasing pathology and help define important factors in deciding the best treatment option. A systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines using the Cochrane Database of Systematic Review, Cochrane Central Register of Controlled Trials, MEDLINE Ovid, and MEDLINE PubMed databases.

Multicompartmental Osteochondral Allografts of Knee and Concomitant High Tibial Osteotomy.

Chondral lesions of the knee can occur secondary to limb malalignment. To address these interrelated problems, a high tibial osteotomy with concomitant osteochondral allograft transfer may be performed. It is important to address these chondral lesions as they often affect the young and active population and cause morbidity in an otherwise healthy population.

Arthroscopic Labral Repair in the Setting of Recurrent Posterior Shoulder Instability.

Posterior shoulder instability, although relatively rare in the general population, is more commonly seen in athletes, especially those in contact sports. Although nonoperative treatment has been associated with satisfactory results in the setting of posterior shoulder instability, conservative management may ultimately fail and lead to recurrence particularly in young, male patients. Both arthroscopic and open repair techniques to address posterior instability have been described, with each showing positive patient-reported outcomes, low risk of recurrence, and considerably high return-to-sport rates.

Superior Capsular Reconstruction With Superimposition of Rotator Cuff Repair for Massive Rotator Cuff Tear.

Massive rotator cuff tears are particularly challenging to treat and severely limit the function of the shoulder. Compared with a small rotator cuff tear, massive tears are more unpredictable and usually present with low tendon quality. When performing an anatomical repair of the rotator cuff, the surgical treatment is often associated with failure of the construct.

Arthroscopic Rotator Cuff Repair With Mini-open Subpectoral Biceps Tenodesis.

With a range of tear characteristics such as chronicity, degree of fatty atrophy, and number of tendons involved as well as varying patient-specific characteristics including age, injury mechanism, and expectations after treatment to consider, proper and successful treatment of a rotator cuff tear is multifactorial and, consequently, challenging. Although conservative management of a rotator cuff tear may be successful, a more severe tear with involvement of more tendons may warrant surgical intervention. Furthermore, additional pathology including biceps tendinopathy may result in greater patient morbidity and an even more complex treatment decision-making process and surgical technique.

Repair of an Isolated Coracoid Fracture With Suture Anchor Fixation.

Coracoid fractures are rare injuries, which may occur in isolation or in association with other shoulder pathology. The mechanism of trauma consists of a strong contraction of the conjoint tendon as a result of direct trauma. The diagnosis is usually difficult and many times overlooked, thereby requiring a high level of suspicion.

Reverse Total Shoulder Arthroplasty With Humeral Head Autograft Fixed Onto Glenoid for Treatment of Severe Glenoid Retroversion.

Advanced glenohumeral osteoarthritis can transform glenoid morphology and, in some cases, is found in association with severe glenoid retroversion. The associated glenoid retroversion leads to difficulty in fixation of the glenoid component in reverse total shoulder arthroplasty. In the context of extreme glenoid wear, structural grafts can be used to restore glenoid volume and version in order for the glenoid component of the reverse total shoulder arthroplasty to be more easily implanted.

Quantitative Assessment of the Coracoacromial and the Coracoclavicular Ligaments With 3-Dimensional Mapping of the Coracoid Process Anatomy: A Cadaveric Study of Surgically Relevant Structures.

Purpose: To perform a quantitative anatomic evaluation of the (1) coracoid process, specifically the attachment sites of the conjoint tendon, the pectoralis minor, the coracoacromial ligament (CAL), and the coracoclavicular (CC) ligaments in relation to pertinent osseous and soft tissue landmarks; (2) CC ligaments' attachments on the clavicle; and (3) CAL attachment on the acromion in relation to surgically relevant anatomic landmarks to assist in planning of the Latarjet procedure, acromioclavicular (AC) joint reconstructions, and CAL resection distances avoiding iatrogenic injury to surrounding structures.

Methods: Ten nonpaired fresh-frozen human cadaveric shoulders (mean age 52 years, range 33-64 years) were included in this study. A 3-dimensional coordinate measuring device was used to quantify the location of pertinent bony landmarks and soft tissue attachment areas.

Posterior Capsulotomy of the Knee: Treatment of Minimal Knee Extension Deficit.

The loss of knee extension, even if minimal, is disabling and considerably affects the individual's quality of life. This loss of extension can be a consequence of prior surgery, including a previous anterior cruciate ligament reconstruction. Although this loss of extension may be treated through an isolated arthroscopic procedure, a more severe case may warrant an invasive approach.

Intra-articular Anterior Cruciate Ligament Reconstruction With Extra-articular Lateral Tenodesis of the Iliotibial Band.

An increasing concern has been given to the rotation stability of the knee in the setting of an anterior cruciate ligament (ACL) reconstruction. This growing interest stems from a better understanding of the rotational stability of the knee afforded by the identification of the anterolateral ligament. Previously, a residual abnormal pivot-shift test had been found after an anatomic single-band reconstruction of the ACL because of a lack of rotational stability, which may lead to the development of osteoarthritis.

Subpectoral Biceps Tenodesis: Interference Screw and Cortical Button Fixation.

Bicep tendon pathology often arises from chronic overuse injuries, acute trauma, or degenerative changes in the glenohumeral joint. These injuries can cause significant shoulder pain, and can greatly limit range of motion and, in turn, activities of daily living. The diagnosis of biceps pathologies can be challenging, because patients often present with nonspecific symptoms.

Arthroscopic Superior Capsule Reconstruction Technique in the Setting of a Massive, Irreparable Rotator Cuff Tear.

Massive, irreparable rotator cuff tears are challenging to treat and associated with pain and severe limitation in shoulder elevation due to the proximal migration of the humeral head and, consequently, subacromial impingement. Furthermore, retraction of the tendons in combination with fat infiltration and muscular weakness results in unpredictable treatment outcomes. While conservative treatment may be warranted for low-demand patients, surgical treatment is often indicated for a successful return to activities of daily living as well as an improved quality of life.

Open Repair of an Anterior Humeral Avulsion of the Glenohumeral Ligament.

A humeral avulsion of the glenohumeral ligament, or HAGL lesion, is an uncommon yet disabling shoulder injury, which leads to complaints of pain and overall inability to properly use the shoulder from patients. The diagnosis of a HAGL lesion is particularly challenging. To arrive at an accurate diagnosis, the use of a magnetic resonance arthrogram is suggested along with high clinical suspicion.

Sternoclavicular Joint Reconstruction in the Setting of Medial Comminuted Clavicle Fracture.

A dislocation of the sternoclavicular joint is a particularly threatening injury given the close proximity of neighboring vital structures. Moreover, a traumatic injury resulting in a comminuted fracture of the medial clavicle in addition to joint instability results in even greater complexity. In the setting of sternoclavicular joint instability, definitive treatment that will lead to complete resolution of symptoms is necessary.

Pectoralis Major Transfer for Treatment of Serratus Anterior Dysfunction in the Setting of Long Thoracic Nerve Palsy.

Symptomatic scapular winging resulting in scapular dyskinesia leads to a wide spectrum of clinical complaints, most notably periscapular pain. The malpositioning of the scapula, termed through use of the acronym SICK (scapular malposition, inferior-medial border prominence, coracoid pain and malposition, and dyskinesia of scapular movement), is due to the irregular activity of one or more of the periscapular muscles. In particular, the serratus anterior, innervated by the long thoracic nerve, is a key muscle that stabilizes the scapula and provides coordinated scapulohumeral rhythm.

Osteotomy of the Tibial Tubercle for Anteromedialization.

Patellofemoral instability is a common cause of anterior knee pain, especially in younger and more active patients. Treatment of instability varies considerably depending on the patient's symptoms as well as the cause of the instability. Lateral instability has a particularly broad spectrum of treatment algorithms including patellar taping, arthroscopy, lateral release, medial patellofemoral ligament (MPFL) reconstruction, MPFL repair, and osteotomy of the tibial tubercle for realignment.

Acromioclavicular Joint Dislocation: Repair Through Open Ligament Transfer and Nonabsorbable Suture Fixation.

Acromioclavicular (AC) joint instability is a fairly common and particularly limiting injury that may result in persistent pain and reduced quality of life. In most cases, conservative management is successful. However, in the case of a severe AC joint dislocation, surgical intervention may be warranted.

Revision Acromioclavicular-Coracoclavicular Reconstruction: Use of Precontoured Button and 2 Allografts.

Injuries to the acromioclavicular (AC) joint are common, particularly in the young and active population. Approximately 9% of all shoulder girdle injuries involve the AC joint, and AC joint dislocations represent approximately 8% of all joint dislocations throughout the body. AC joint injuries are graded as type I through type VI according to the Rockwood classification.

Simultaneous Radiographic Technique to Evaluate Ankle Instability.

The use of ankle stress radiographs is common to evaluate ankle instability. However, the majority of the studies report the use of a manual method to apply the stress, increasing radiation exposure to the physician. Furthermore, as reported in other studies, the force applied during the stress may vary between examiners according the strength and experience.

The External Rotation Radiographic Technique for Posterolateral Injury.

Posterolateral corner injuries are a severe and often unrecognized pathology. Injuries to these structures are difficult to identify using magnetic resonance images. Physical examination tests including the dial test, frog-leg test, and varus stress test can be difficult to perform.

Simultaneous Bilateral Knee Valgus Stress Radiographic Technique.

The medial collateral ligament is the most commonly injured knee ligament. Valgus stress radiographs are reported to be an effective way to quantify the medial compartment opening. However, most of the techniques require the presence of a physician in the radiograph room to apply a manual valgus stress force, and can only be performed in 1 knee at a time.

Qualitative and Quantitative Anatomy of the Proximal Humerus Muscle Attachments and the Axillary Nerve: A Cadaveric Study.

Purpose: To provide a quantitative and qualitative anatomic analysis of the pectoralis major, teres major, and latissimus dorsi on the humerus, as well as the deltoid tendinous attachments on the proximal humerus and acromion, and to quantitatively characterize the humeral course of the axillary nerve.

Methods: Ten nonpaired, fresh-frozen human cadaveric shoulders were analyzed. A portable coordinate-measuring device quantified the location of bony landmarks and tendon attachment areas.

Arthroscopic Bony Resection for Treatment of Symptomatic Bipartite Patella.

Bipartite patella is a common pathology, affecting 2% to 3% of the population. Usually these cases are bilateral and asymptomatic. However, a patient with a bipartite patella may complain of pain, which is most likely related to fragment mobility.
