The Hauser operation for patellar dislocation. 3-32-year results in 63 knees

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomedical Engineering

Background:

• Patellar dislocation is a common knee injury.
• The Hauser procedure is a surgical technique used to address recurrent patellar instability.
• Long-term outcomes and complications of the Hauser operation require further investigation.

Purpose of the Study:

• To evaluate the long-term efficacy and safety of the Hauser operation for patellar dislocation.
• To assess the rates of patellar stability, pain relief, and development of arthrosis after the procedure.
• To identify potential risk factors for adverse outcomes, such as age at surgery.

Main Methods:

• Retrospective case series of patients who underwent the Hauser operation.
• Data collection included patient demographics, surgical details, and clinical outcomes.
• Follow-up assessments evaluated patellar stability, pain levels, and radiographic evidence of arthrosis.

Main Results:

• A significant proportion of knees achieved good patellar stability post-operatively.
• However, a substantial number of patients continued to experience pain.
• High rates of patellar and femorotibial arthrosis were observed, particularly in patients operated on before age 15.

Conclusions:

• The Hauser operation can restore patellar stability but has limitations regarding pain relief and the development of osteoarthritis.
• Younger patients undergoing the procedure may be at increased risk for long-term complications, including axial deformities.
• Further research is needed to optimize surgical techniques and patient selection for patellar instability.
