Dosimetric comparison between proton beam therapy, intensity modulated radiation therapy, and 3D conformal therapy for soft tissue extremity sarcoma.

Purpose/objectives: Proton beam therapy (PBT) may provide a dosimetric advantage in sparing soft tissue and bone for selected patients with extremity soft sarcoma (eSTS). We compared PBT with photons plans generated using intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT).

Materials/methods: Seventeen patients previously treated with pencil beam scanning PBT were included in this study.

Early Experience Using Proton Beam Therapy for Extremity Soft Tissue Sarcoma: A Multicenter Study.

Purpose: Proton beam therapy (PBT) may provide an advantage when planning well-selected patients with extremity soft tissue sarcoma (eSTS), specifically for large, anatomically challenging cases. We analyzed our early experience with PBT on toxicity and outcomes.

Materials And Methods: A retrospective study was performed for eSTS treated between June 2016 and October 2020 with pencil beam scanning PBT at 2 institutions.

Nonoperative Management of Minimally Displaced Patellar Sleeve Fractures.

Patellar sleeve fractures primarily occur in the adolescent population from a rapid contraction of the quadriceps with the knee in a flexed position. Several small case reports describe operative reduction and fixation for displaced fractures. However, there is sparse literature on nonoperative management of these injuries.

Open Anatomic Reconstruction of the Medial Collateral Ligament and Posteromedial Corner.

Injuries to the medial collateral ligament (MCL) and posteromedial corner can occur in isolation or in the setting of multiligamentous knee injuries. Reconstruction of the MCL and posteromedial corner is indicated in the setting of a multiligamentous knee injury. Isolated cases failing nonoperative treatment may also undergo surgical treatment.

Surgical Outcomes of Medial Versus Lateral Multiligament-Injured, Dislocated Knees.

Purpose: To compare clinical and functional outcomes of surgically treated medial and lateral knee dislocations.

Methods: A retrospective review of the medical records of patients who presented with knee dislocations was conducted. We identified patients who underwent surgical treatment of KDIII-M (anterior cruciate ligament/posterior cruciate ligament/medial collateral ligament) or KDIII-L (anterior cruciate ligament/posterior cruciate ligament/lateral collateral ligament) knee dislocation as documented by the Schenck classification.

All-Inside Posterior Cruciate Ligament Reconstruction: GraftLink Technique.

Posterior cruciate ligament (PCL) injuries account for nearly 20% of knee ligament injuries. PCL injuries can occur in isolation or, more commonly, in the setting of multiligamentous knee injuries. Isolated PCL disruptions are commonly treated nonoperatively; however, symptomatic grade III injuries, as well as PCL injuries found in multiligamentous injuries, are frequently treated surgically.

Low-Velocity Knee Dislocations in Obese and Morbidly Obese Patients.

Background: Knee dislocations from minor trauma have been reported sparsely in the literature. The consensus is that these injuries tend not to be associated with neurovascular compromise.

Purpose: To present a series of atraumatic knee dislocations in obese and morbidly obese patients and to compare operative versus conservative treatment.

Posterolateral Reconstruction of the Knee: Two-Tailed Surgical Techniques.

Reconstruction of the posterolateral corner of the knee using two-tailed techniques involved grafts originating from the femur and inserting on the proximal tibia and fibular head. This method reconstructs the fibular collateral ligament, popliteofibular ligament, and popliteus tendon using anatomically placed grafts. This article describes the history, anatomy, indications, and authors' preferred technique for a two-tailed posterolateral corner reconstruction.

Are meniscal tears and articular cartilage injury predictive of inferior patient outcome after surgical reconstruction for the dislocated knee?

Purpose: A paucity of data exists on the effects of articular cartilage and meniscal injury in the setting of knee dislocations. The purpose of this study is to determine whether concomitant intra-articular injuries at the time of multiligament reconstruction for knee dislocation are associated with inferior outcomes.

Methods: The records of patients who underwent surgical treatment for multiligament knee injury between 1992 and 2012 were retrospectively reviewed.

Treatment of Patellofemoral Cartilage Lesions in the Young, Active Patient.

Articular cartilage lesions of the patella and trochlea are commonly encountered in the young and active patient. These defects can be classified as chondral or osteochondral, and then further described according to size, location, and etiology. Early surgical intervention is often indicated for traumatic injuries resulting in osteochondral damage, including acute patellofemoral dislocation.

Anterior horn lateral meniscus tear, repair, and meniscectomy.

The purpose of this study was to describe the effect of anterior horn of the lateral meniscus (AHLM) tears on tibiofemoral contact pressures and the ability to restore normal parameters with repair. Eight fresh-frozen cadaveric knees were used. The specimens were subjected to a load of 1,000 N at 0 and 30 degrees of flexion and peak pressure, force and contact area were recorded.
