Assessment of the Radiographic Angular Parameters in the Coronal Plane of the Lower Limbs in Subjects without Knee Osteoarthritis in a Reference Hospital of the Brazilian Unified Health System.

 The present study aims to demonstrate the radiological angular parameters of a sample of patients treated at our institution and to compare the radiological abnormalities with other classifications or parameters from the literature.  We evaluated a sample of patients submitted to panoramic radiographic examinations of the lower limbs. The inclusion criteria were: (1) Patients without knee osteoarthritis as assessed by an orthopedist.

Medial Gradual Opening Osteotomy of the Tibia With Monolateral External Fixator for Correcting the Varus Deformity of the Tibia.

Correction of the varus deformities in the tibia is necessary because of the excessive pressure exerted on the medial compartment of the knee, which intensifies the degenerative process. Correction strategies encompass a variety of approaches and depend on the patient's individual characteristics, age, soft tissue condition, and the orthopaedic surgeon's experience with different surgical materials. Size and location of the deformity, whether gradual or acute, play crucial roles in choosing the most appropriate material and shape.

Gradual Correction of Valgus Deformities of the Tibia Using a Monolateral External Fixator.

Objective: To present a review of patients subjected to gradual correction of a valgus deformity of the tibia using a monolateral external fixator.

Method: This retrospective review included patients from January 2012 to May 2022 who met the following inclusion criteria: deviation of mechanical axis of the limb due to valgus deformity of the tibia; tibial deformity in the coronal plane on radiographic examination; a documented outpatient pre-operative evaluation by an orthopaedic surgeon and age between 10 and 70 years. The following exclusion criteria were applied: the presence of another tibia deformity preventing gradual correction using the proposed assembly; skin conditions incompatible with the surgical procedure; inadequate pre- or post-operative radiological evaluation; and insufficient information in the medical records.

Lateral Gradual Opening Osteotomy of the Tibia With Monolateral External Fixator for Correcting the Valgus Deformity of the Tibia.

The valgus deformity in the tibia requires correction because it places increased pressure on the lateral compartment of the knee, intensifying the degenerative process. Correction strategies are diverse and depend on patient profile, age, and soft-tissue conditions as well as the orthopaedic surgeon's experience with different surgical materials. Deformity size and location are the primary factors contributing to material and shape choice, whether gradual or acute.
