Summary
Inferior patellar dislocation is a rare injury in osteo-arthritic knees. This case highlights recurrence, surgical repair, and intra-articular damage in an elderly patient.
Area of Science:
- Orthopedic Surgery
- Geriatric Medicine
- Sports Medicine
Background:
- Inferior patellar dislocation is an uncommon knee injury.
- Degenerative osteo-arthritis can predispose to rare knee pathologies.
- Elderly patients present unique challenges in managing orthopedic trauma.
Observation:
- An 80-year-old female presented with an inferior dislocation of the patella.
- The patient had a pre-existing diagnosis of osteoarthritis in the affected knee.
Findings:
- This case represents the first documented instance of recurrent inferior patellar dislocation in a degenerate knee.
- Operative reduction was necessary to address the dislocation.
- Significant intra-articular damage was identified in conjunction with the dislocation.
Implications:
- This case underscores the potential for rare traumatic knee injuries, such as inferior patellar dislocation, even in the presence of severe osteoarthritis.
- It emphasizes the importance of considering operative intervention for recurrent or complex patellar dislocations in the elderly population.
- The findings highlight the need for thorough intra-articular assessment in such cases to manage associated damage effectively.
