Summary
This study presents a novel single-stage treatment for permanent post-traumatic patellar dislocation using total knee arthroplasty. The procedure showed a surprisingly good recovery, even after decades of living with the condition.
Area of Science:
- Orthopedics
- Trauma Surgery
- Knee Arthroplasty
Background:
- Permanent post-traumatic patellar dislocation is rare and often misdiagnosed as congenital dislocation.
- Current treatment options are not well-defined, including observation, surgical realignment, or patellectomy.
Observation:
- A unique case of long-standing patellar dislocation, present for nearly 40 years, leading to secondary osteoarthritis.
- The patient maintained reasonable function despite the chronic dislocation.
Findings:
- This is the first reported case of using conventional non-constrained total knee arthroplasty with patellar resurfacing and soft tissue realignment in a single stage for this condition.
- The patient experienced a surprisingly good recovery following the total knee replacement.
Implications:
- This single-stage approach offers a potential new treatment strategy for complex patellar dislocations.
- Highlights the possibility of successful knee replacement in patients with chronic, previously debilitating patellar instability.
