Evaluation of Short-Term Clinical Results Following Isolated MPFL Reconstruction with Superficial Quadriceps or Hamstring Tendon in Patellar Dislocation: MPFL Reconstruction Using Quadriceps Versus Semitendinosus Autograft

Orthopaedic Journal of Sports Medicine | 2026 | Yuki Suzuki, Yoshimitsu Aoki, Chiharu Inoue, Hisashi Matsumoto

Objectives: While hamstring autografts are widely used in medial patellofemoral ligament reconstruction (MPFLR), concerns have arisen regarding complications associated with the patella bone tunnel and fixation hardware, such as endobutton. As an alternative, the superficial quadriceps tendon (SQ) has also been used presently. The purpose of the present study is to compare the...

Outcomes of a Combined Procedure of Tibial Tubercle Proximalization, MPFL Reconstruction and Extensive Lateral Release for Revision Treatment of Habitual Patellar Dislocation in Flexion in Skeletally Mature Patients

Orthopaedic Journal of Sports Medicine | 2025 | Zhijun Zhang, Daofeng Wang, Xuesong Wang, Hui Zhang

Background: Habitual patellar dislocation in flexion (HPD-F) is a rare condition in skeletally mature patients. Current literature reports that tibial tubercle proximalization has achieved favorable clinical outcomes for such patients. However, there are no studies to date reporting the clinical outcomes of revision surgery for skeletally mature HPD-F patients after failure of...

Paper 54: MPFL Repair has a Higher Failure Rate at Long-term Follow-up compared to MPFL Reconstruction for Recurrent Patellar Instability

Orthopaedic Journal of Sports Medicine | 2022 | Ryan Wilbur, Bryant Song, Jory Wasserburger, Christopher Camp

Objectives: The medial patellofemoral ligament (MPFL) is the primary soft tissue restraint to lateral patellar translation and is often disrupted with a lateral patellar dislocation. Surgical management for recurrent patellar instability focuses on restoring MPFL function with repair or reconstruction techniques. Recent studies have favored reconstruction over repair, but no lo...

INCIDENCE OF 2 nd SURGERY AFTER MPFL RECONSTRUCTION AND SIMULTANEOUS OSTEOCHONDRAL FRACTURE FIXATION IN PEDIATRIC PATIENTS TREATED FOR PATELLAR DISLOCATION

Orthopaedic Journal of Sports Medicine | 2020 | Lindsay M. Schlichte, Alexandra H. Aitchison, Daniel W. Green

Background: Osteochondral fractures occur in 5-15% of cases of acute or recurrent patellar dislocations. In these settings, early surgical intervention with biodegradable fixation nails is recommended to optimize healing. Purpose: The purpose of this study was to determine the incidence of recurrent instability and second surgery following osteochondral fracture fixation with c...

Short Oblique Patellar Tunnels for Patellar Fixation Do Not Increase Fracture Risk in MPFL Reconstruction: A Retrospective Cohort Study

Orthopaedic Journal of Sports Medicine | 2020 | Milos Lesevic, Matthew Deasey, Zachary Burnett, David Diduch

Objectives: The current standard of care for recurrent patellar instability is reconstruction of the medial patellofemoral ligament (MPFL), the primary soft tissue constraint to lateral subluxation of the patella. Historically, transpatellar bone tunnels have been associated with increased rates of patella fracture. To avoid this dreaded outcome, many surgeons now employ suture...
