Results of 211 total knee arthroplasty operations were retrospectively evaluated to identify patients with knees at greatest risk for the development of patellofemoral complications and to determine the incidence and type of patellofemoral complications associated with different patellar implants. Patellofemoral complications occurred in 27 knees (12.8%). Osteoarthritis and obesity were associated with an increased incidence of patellofemoral problems. Significantly higher rates of patellofemoral complications were noted with metal-backed patellar implants and with patellar components implanted without cement. The loosening rate with cementless fixation was 13.5%. The lowest rate of patellofemoral complications following total knee arthroplasty was obtained with all-polyethylene domed patellar components implanted with cement.

Decreased Association Between Patellar Axial Malalignment and Patellar Height and Increased Association Between Patellar Axial Malalignment and Tibial Tubercle-Trochlear Groove During Weightbearing.
Clin Orthop Relat Res
January 2025
Department of Radiology, Chongqing Health Center for Women and Children/Women and Children's Hospital of Chongqing Medical University, Chongqing, PR China.
Background: Nonweightbearing preoperative assessments avoid quadriceps contraction that tends to affect patellar motion and appear to be inaccurate in quantifying anatomic factors, which can lead to incorrect corrections and postoperative complications.
Questions/purposes: (1) Does the relationship of patellar axial malalignment and other anatomic factors change during weightbearing? (2) What anatomic factor was most strongly correlated with recurrent patellar dislocation during weightbearing?
Methods: This prospective, comparative, observational study recruited participants at our institution between January 2023 and September 2023. During this time, all patients with recurrent patellar dislocations received both weightbearing and nonweightbearing CT scans; control patients who received unilateral CT scans because of injuries or benign tumors received both weightbearing and nonweightbearing CT scans.
Medial patellofemoral ligament reconstruction using synthetic suture tape: A systematic review of biomechanical and clinical outcomes.
J Clin Orthop Trauma
February 2025
Utah Valley Orthopedics and Sports Medicine, 1157 N 300 W, Provo, UT, 84604, USA.
Purpose: To review outcomes of medial patellofemoral ligament reconstruction (MPFLR) using synthetic suture tape in biomechanical and clinical studies.
Methods: A comprehensive literature search was performed in three databases. Studies reporting biomechanical and/or clinical outcomes of MPFLR using synthetic suture tape were included.
In functionally aligned total knee arthroplasty, femoral component rotation follows the transepicondylar axis to achieve flexion balance.
Knee Surg Sports Traumatol Arthrosc
January 2025
Clinical Research Department, Sydney Knee Specialists, Kogarah, New South Wales, Australia.
Purpose: In functionally aligned (FA) total knee arthroplasty (TKA), femoral component rotation (FCR) is personalised to optimise flexion gap balance. As axial malalignment has been attributed to patellofemoral complications, this study assessed FA FCR in relation to the surgical transepicondylar axis (TEA) and early implant survivorship.
Methods: We analysed 446 robotic-assisted primary TKAs in 393 patients using FA with preresection gap balancing.
Heterogeneity in the use of osseous risk factors and limited use of relevant patient-reported outcome measurements in studies investigating treatment of patellar dislocation: A scoping review.
Knee Surg Sports Traumatol Arthrosc
January 2025
Sports Orthopedic Research Center-Copenhagen (SORC-C), Department of Orthopedic Surgery, Copenhagen University Hospital, Amager-Hvidovre, Denmark.
Purpose: The treatment of patellar dislocation is tailored based on the presence or absence of osseous risk factors. The purpose of this scoping review was to investigate whether existing research addresses patient differences by mapping the use of osseous risk factors and patient-reported outcome measures (PROMs) in studies investigating the treatment of patellar dislocation.
Methods: This study was a scoping review conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews.
Trochleoplasty in Pediatric Patients - A Systematic Review.
Iowa Orthop J
January 2025
Department of Orthopaedics, The Children's Hospital of Philadelphia, Philadelphia, Pennsylvania, USA.
Background: Trochleoplasty is a surgical consideration for the treatment of high-grade trochlear dysplasia. The safety profile of this procedure remains particularly unclear in the skeletally immature population where concerns exist regarding physeal arrest and the development of premature patellofemoral arthritis. The purpose of this study was to systematically review the literature to evaluate trochleoplasty use, outcomes and complications observed among pediatric patients.
