📌Semimembranosus Bursa:
- Horseshoe-shaped synovial bursa around the semimembranosus tendon near posteromedial tibial rim
- Inflamed/distended bursa presents as a synovial-lined space wrapping the tendon
- Demonstrates characteristic reverse 'J' shape or 'inverted-U' shape on imaging
✅Direct Arm of Semimembranosus Tendon
- Principal attachment of the semimembranosus tendon
- Attaches to posteromedial aspect of tibia, just distal to the joint line
- Forms a C-shaped 5-mm-thick band with the anterior arm
✅Anterior Arm of Semimembranosus Tendon
- Seen on peripheral medial sagittal images, curving anteriorly
- Appears as a round hypointense structure on coronal images, adjacent to medial tibia, passing under the MCL
