Patella Baja in Total Knee Arthroplasty

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Patella baja, characterized by low-lying kneecaps, is a known complication following total knee arthroplasty (TKA).
• It can lead to anterior knee pain, patellofemoral impingement, and restricted range of motion, negatively impacting functional outcomes.
• Previous surgeries like ACL reconstruction or prior TKAs are significant risk factors.

Purpose of the Study:

• To review the diagnostic methods for identifying patella baja in TKA patients.
• To explore various surgical management strategies for correcting patella baja.
• To evaluate the outcomes associated with different surgical interventions.

Main Methods:

• Review of literature on patella baja diagnosis and treatment in TKA.
• Analysis of diagnostic tools including Insall-Salvati and Blackburne-Peel ratios for patellar height.
• Compilation of surgical techniques such as tibial tubercle osteotomy, component revision, and tendon modification.

Main Results:

• Accurate differentiation between true and pseudo patella baja is crucial for effective management.
• Multiple surgical options exist, each with specific indications and potential benefits.
• Outcomes vary depending on the chosen surgical approach and underlying etiology.

Conclusions:

• Patella baja is a multifactorial complication in TKA requiring precise diagnosis.
• Surgical correction strategies offer potential for improved function and pain relief.
• Further research into optimizing surgical outcomes for patella baja is warranted.
