Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanical Engineering

Background:

  • Recurrent patellar instability often necessitates surgical intervention when conservative treatments are insufficient.
  • Identifying predisposing factors for patellar instability is crucial for successful patient management.

Purpose of the Study:

  • To evaluate the efficacy of medial patellofemoral ligament (MPFL) reconstruction for recurrent patellar instability.
  • To describe a reliable technique for anatomic MPFL reconstruction.
  • To assess the impact of secure graft fixation on early rehabilitation and outcomes.

Main Methods:

  • MPFL reconstruction utilizing a technique for precise anatomic tunnel positioning.
  • Rigid fixation of the graft within bone tunnels using an interference fit.
  • Early range of motion and rehabilitation protocols initiated post-surgery.

Main Results:

  • The described MPFL reconstruction technique provides a viable surgical option for recurrent patellar instability.
  • Anatomic tunnel placement and rigid fixation contribute to minimizing concerns regarding graft failure.
  • Early rehabilitation is facilitated by the secure graft fixation method.

Conclusions:

  • MPFL reconstruction is an effective treatment for patients with recurrent patellar instability unresponsive to nonoperative care.
  • The described surgical technique ensures reliable anatomic tunnel placement and secure graft fixation.
  • This approach allows for early mobilization and rehabilitation, reducing the risk of graft failure.
