Prompt: Rotator Cuff Repair Physiotherapy Referral Letter

Draft a physiotherapy referral letter following arthroscopic 
rotator cuff repair.

Procedure: [[procedure — e.g. "arthroscopic repair of 
full-thickness supraspinatus tear, single anchor fixation"]].
Patient: aged [[patient_age — e.g. "52"]], 
[[hand_dominance — e.g. "right-hand dominant"]], 
[[occupation — e.g. "office worker with occasional light 
manual tasks"]].

Rehabilitation protocol:
Phase 1 ([[weeks — e.g. "weeks 0–6"]]): 
[[phase1 — e.g. "sling immobilisation; pendulum exercises only; 
no active shoulder movement; no lifting; 
scapular retraction exercises permitted"]]

Phase 2 ([[weeks — e.g. "weeks 6–12"]]): 
[[phase2 — e.g. "remove sling; passive range of motion; 
progress to active-assisted by week 8; 
target 90 degrees elevation by week 10"]]

Phase 3 ([[weeks — e.g. "weeks 12+"]]): 
[[phase3 — e.g. "active strengthening — begin scapular 
stabilisers, progress to rotator cuff strengthening; 
avoid resisted external rotation until week 16"]]

Goals: [[goals — e.g. "full passive range of motion by 
4 months; return to light occupation at 3 months; 
return to full overhead work at 6 months"]]

Red flags to report back: [[red_flags — e.g. "failure to 
achieve expected passive ROM milestones; significant pain 
with passive movement; suspected re-tear"]]

Format: professional referral letter.
