The operative management of patella malalignment

Area of Science:

• Orthopedics
• Biomechanics
• Sports Medicine

Background:

• Patellofemoral joint pathology causes anterior knee pain, a common complaint in clinical practice.
• Successful management hinges on diagnosing chondral defects and identifying associated pathomechanical factors.
• Understanding the pathoanatomic basis guides treatment by addressing imbalances and anatomical abnormalities.

Purpose of the Study:

• To review the operative management of patellofemoral malalignment.
• To discuss indications for surgery, available techniques, and their effectiveness.
• To emphasize the need for improved evidence in surgical outcomes.

Main Methods:

• Review of surgical management techniques for patellofemoral malalignment.
• Analysis of indications, procedures, and reported effectiveness.
• Evaluation of existing literature, noting methodological inconsistencies.

Main Results:

• Numerous surgical procedures exist, with many modifications over time.
• The majority of studies are retrospective and lack well-defined patient populations.
• Significant methodological inconsistencies limit the evidence base for most procedures.

Conclusions:

• Patellofemoral realignment surgery aims to stabilize the extensor mechanism and optimize joint loading.
• Current evidence supporting various surgical techniques is limited due to study design.
• Further high-quality research is needed to establish robust evidence for surgical interventions.
