Predicting Factors for the Outcome of Surgical Treatment for Patellar Instability

Predicting Factors for the Outcome of Surgical Treatment for Patellar Instability

The purpose of the study is:

1. to analyze the success of operative stabilization of the patellar joint with the reconstruction of the medial patellofemoral ligament (MPFL) in terms of the subjective status of the knee, the general quality of life, and physical activity
2. to study the influence of specific preoperative (demographic and anamnestic data of the patient, radiological parameters of the knee joint) and intra-operative factors (place of femoral insertion of MPFL graft, patella height, degree of damage to the cartilaginous surfaces of the knee joint) on the subjective outcome of surgical treatment.

Inclusion Criteria:

• patients over 18 years of age
• surgical intervention with MPFL reconstruction
• with or without tibial tuberosity transposition (TTT).

Exclusion Criteria:

• trochleoplasty,
• corrective knee osteotomy
• reparative cartilage treatment
• reconstruction of other knee ligaments
• meniscus repair
• movement impairments
• plegia
• paresis
• neuromuscular diseases
• participation rejection
• rejection to complete the control questionnaires
• lack of understanding of the Slovenian language
