A _____ type of contracture tends to be most difficult to regain optimal mobility and may be irreversible.

A _____ type of contracture tends to be most difficult to regain optimal mobility and may be irreversible.

• A. Arthrogenic
• B. Fibrotic
• C. Myogenic
• D. Elastic

Answer: (B)

The key idea is that contracture reversibility depends on the tissue changes underlying it. A fibrotic contracture involves dense scar tissue and collagen remodeling in periarticular structures and often within the muscle fascia or joint capsule. This scar tissue becomes nonelastic and adherent, drastically reducing tissue glide and extensibility. Because these structural changes are long-standing and less responsive to stretching or therapy, mobility gains can be limited and, in some cases, irreversible. In contrast, arthrogenic contractures come from intra-articular problems like adhesions or effusion that can improve once the joint pathology is addressed. Myogenic contractures stem from muscle shortening but still retain potential for reversal with targeted lengthening and strengthening. Elastic contractures imply tissues with preserved elasticity that regain length quickly with appropriate movement. Thus, the fibrotic type is the one most likely to be difficult to regain full mobility and potentially irreversible.
