AI Article Synopsis

  • Patellar luxation is a frequent orthopedic issue in dogs, especially in small breeds, with medial luxation being more common than lateral.
  • Diagnosis relies on clinical signs of instability, but imaging is needed to evaluate skeletal deformities and guide treatment.
  • Surgical approaches often require a combination of techniques, and while complications can occur, the overall prognosis is positive, with many dogs resuming normal limb function.

Article Abstract

Patellar luxation is a common orthopedic problem in dogs. Medial luxation is more common than lateral luxation and is usually diagnosed in dogs of small breed. Diagnosis is based on clinical evidence of patellar instability; however, diagnostic imaging is required to assess the amount of skeletal deformity and then the most appropriate method of treatment. Surgical options include both soft tissue and osseous techniques, however, in most of the cases, a combination of more procedures is used to achieve the correction of the luxation. Complication rate is generally low and the most common complications include reluxation and implant-associated complications. Prognosis is generally favorable, with most of the dogs returning to normal limb function. This article describes patellar luxation features in dogs, including clinical presentation, diagnosis, and treatment options available.

Effect of surgical treatment on relative tibial external rotation in patients with recurrent patellar dislocation.

Knee

December 2024

Graduate School of Guangzhou University of Chinese Medicine, Guangzhou, Guangdong, China; Second Affiliated Hospital of Guangzhou Medical University, Guangzhou, Guangdong, China. Electronic address:

Background: In the knee joints of patients with recurrent patellar dislocation (RPD), an increased relative tibial external rotation (rTER) is often observed. However, the changes in this parameter pre- and postoperatively remain unclear.

Purpose: The purpose of this study was to reveal preoperative and postoperative changes in rTER in patients with RPD.

Background: Consequences of osteochondral fractures associated with patellar dislocation can be severe for younger patients. Precise 3-dimensional characterization of fracture location, size, frequency, and radiographic associations remain undefined in this population.

Purpose: (1) To define the topographic characteristics of osteochondral fractures in pediatric and adolescent patients with first-time patellar dislocations and (2) to determine the relationship between these characteristics and radiographic and patient factors.

Most cases of patellar dislocation can be reduced spontaneously or manually without sedation. To date, only one case of arthroscopic reduction for a lateral locked patellar dislocation has been reported, with a short follow-up period. Herein, we report the case of a 22-year-old man with a lateral locked patellar dislocation for whom we performed arthroscopic reduction and repair of the medial structure, which stabilized the patella medially.

Electronic address:

Purpose: To review patients with recurrent patellar dislocation surgically treated with robot-assisted medial patellofemoral ligament (MPFL) reconstruction compared with patients who underwent surgery using the traditional freehand technique.

Methods: A retrospective cohort study was performed to identify patients who underwent MPFL reconstruction from January 2020 to December 2023 in our hospital. The inclusion criteria were: patients aged from 15 to 50 years; patellar dislocation occurred two or more times; a Merchant view or computed tomography (CT) scan indicating patellofemoral joint malalignment, external patellar inclination, or lateral patellar dislocation; underwent MPFL reconstruction via robot-assisted or traditional freehand technique; complete medical records and imaging data before and after surgery; a minimum of 1 year of postoperative follow-up.

Patellofemoral instability (PFI) is a multifactorial condition typically observed following initial traumatic patellar dislocation. PFI depends on various factors such as limb alignment, bony structure, and the integrity of static and dynamic stabilizers. Patients with below-knee amputation have a higher risk of experiencing PFI.
