Abstract:
We report a case of mucoid degeneration of the posterior cruciate ligament (PCL). A 37-year-old male had suffered from right knee pain for several years. The active range of motion of his right knee was -30 extension and 100 flexion, with terminal pain. Magnetic resonance imaging (MRI) showed low proton density and T2WI with fat saturation-high signals in the PCL. Arthroscopic resection of the PCL was carried out, with immediate relief of his symptoms. This was a very rare case of mucoid degeneration of the PCL in a young healthy man. If this disease is considered preoperatively, it can be diagnosed based on characteristic MRI findings.
Insights
Mucoid degeneration of the posterior cruciate ligament (PCL) is rare in young adults. Characteristic MRI findings can aid in diagnosing this PCL condition, leading to effective treatment.
Area of Science:
- Orthopedic Surgery
- Musculoskeletal Imaging
Background:
- Mucoid degeneration of the posterior cruciate ligament (PCL) is an uncommon condition.
- It can cause chronic knee pain and limited range of motion.
Observation:
- A 37-year-old male presented with several years of right knee pain.
- Physical examination revealed limited extension and flexion with terminal pain.
- Magnetic resonance imaging (MRI) demonstrated characteristic findings in the PCL.
Findings:
- MRI revealed low proton density and T2WI with fat saturation-high signals within the PCL.
- Arthroscopic resection of the affected PCL was performed.
- The patient experienced immediate symptom relief following the procedure.
Implications:
- This case highlights the importance of considering PCL mucoid degeneration in young, active individuals with knee pain.
- Characteristic MRI findings are crucial for preoperative diagnosis.
- Surgical intervention can effectively resolve symptoms associated with PCL mucoid degeneration.
