tendon-bone-interface-enthesis
An orthopaedic registrar is preparing a presentation on rotator cuff healing after surgical repair. They are reviewing the normal anatomy of the tendon-bone insertion site (enthesis) to understand why healing after repair often results in a mechanically inferior interface. **What are the four distinct zones of a normal direct (fibrocartilaginous) enthesis from tendon to bone?**
Mark each as TRUE or FALSE
Tendon → Loose connective tissue → Dense connective tissue → Bone
Tendon → Unmineralized fibrocartilage → Mineralized fibrocartilage → Bone
Tendon → Hyaline cartilage → Calcified cartilage → Bone
Tendon → Periosteum → Cortical bone → Cancellous bone
Tendon → Synovium → Fibrous tissue → Bone
