What rotator cuff repair actually involves

The rotator cuff is a sleeve of four tendons — supraspinatus, infraspinatus, teres minor, and
subscapularis — that wraps the ball of the shoulder and anchors it in the socket while the arm
lifts and rotates. When one of those tendons tears away from the bone (the supraspinatus is torn
most often), repair surgery reattaches it: the surgeon places small suture anchors into the
greater tuberosity of the humerus and stitches the tendon edge back down to its footprint so it
can heal to bone. Most repairs today are done arthroscopically, through a few small portals with
a camera; larger or retracted tears sometimes call for a mini-open approach. Depending on what
the surgeon finds, the procedure may include trimming inflamed bursa, smoothing bone spurs under
the acromion, or addressing the biceps tendon that runs through the same space.

To be direct about our role: Injury Recovery MD does not perform rotator cuff
surgery. We are the practice on either side of it — the exam and MRI work-up that
establishes what is actually torn, the conservative-care trial that many cuffs respond to, the
referral to a shoulder surgeon when repair is the clinically indicated path, and the structured
rehabilitation that determines how much function the repaired shoulder gets back.

How crashes and work injuries tear the cuff

Two mechanisms bring most traumatic cuff tears through our doors. In a car accident, the
driver’s instinct is to lock the arms against the steering wheel — the impact drives force
straight up the braced arm into the shoulder — or the shoulder itself strikes the door frame in
a side impact. A fall onto an outstretched hand during the crash sequence does the same thing.
At work, the classic injuries are a fall from a ladder caught by one arm, a heavy object
overhead that shifts suddenly, or years of overhead trades — painting, electrical, warehouse
racking — that fray the tendon until one lift finishes it.

The symptom pattern is distinctive: a deep ache over the outer shoulder, pain that flares
when the arm works overhead or reaches behind the back, weakness lifting the arm away from the
body, and — almost universally — night pain lying on that side. If that
describes your shoulder, start with our rotator cuff tear
hub; if the diagnosis isn’t clear yet, the broader
shoulder pain page walks through the other possibilities the exam
has to rule out.

Tear grades — and when repair beats rehab

Not every torn cuff is a surgical cuff. The decision turns on what the MRI and exam show:

• Partial-thickness tears — the tendon is frayed or torn on one surface but
  still attached. These are usually managed conservatively first: physical therapy to restore
  cuff and shoulder-blade mechanics, activity modification, and anti-inflammatory care.
• Full-thickness tears — the tendon has pulled completely through, leaving
  a defect. Surgeons describe them by size, from small (under 1 cm) through medium and
  large to massive (over 5 cm or involving multiple tendons). A full-thickness tear does
  not reattach itself, though some patients function well without repair.

Repair tends to enter the conversation when a tear is full-thickness and clearly traumatic —
a shoulder that worked normally until the accident and hasn’t since — when there is
marked weakness on testing (a positive drop-arm sign, for example), or when a properly done
course of conservative care hasn’t restored function. Timing matters more for the cuff
than for many injuries: with a complete traumatic tear, the detached tendon can retract and the
muscle behind it can atrophy over months, which makes later repair technically harder. That is
a reason to get a definitive diagnosis promptly — not a reason to rush past rehab that may make
surgery unnecessary. Our job is the honest version of that work-up: examine the shoulder, get
the right imaging, run the conservative trial where it’s appropriate, and coordinate the
surgical referral without delay when it isn’t.

Who pays for rotator cuff surgery — workers’ comp and No-Fault, factually

The rotator cuff is one of the most common surgically treated shoulder injuries in the New
York workers’ compensation system, and if your tear happened on the job, workers’
comp — not your health plan — is generally the payer for medically necessary,
causally related care: the evaluation, the MRI, conservative treatment, the surgery itself when
indicated, and the months of rehab that follow. Care runs under the Workers’ Compensation
Board’s Medical Treatment Guidelines for shoulder injuries, certain procedures require
insurer authorization before they happen, and wage-replacement benefits depend on your average
weekly wage and degree of disability. The documentation connecting the tear to the work
incident is what the whole claim rests on — see how we handle it on our
workers’ comp injury care page.

If the tear came from a car accident, New York No-Fault (PIP) applies instead: basic coverage
provides up to $50,000 per person for medically necessary accident care —
surgery and rehabilitation draw from that same pool — plus 80% of lost earnings up to $2,000 per month for up to three years
per month for up to three years. The claim generally opens only after written notice (Form NF-2) reaches the
carrier within 30 days of the crash (carriers may accept late notice with reasonable justification), which is one more reason the first evaluation shouldn’t
wait. As a no-fault doctor, we open and manage that claim and
bill the carrier directly. Where benefits are disputed or exhausted mid-treatment, care can
sometimes continue under a lien or letter of protection
arrangement. In every case, coverage decisions belong to the carrier under the applicable
policy — what we control is the record: exam findings, imaging, and treatment notes that
document the injury and its cause.

The sling-to-strength rehab arc

Rotator cuff repair has one of the slowest early timelines in orthopedic rehab, for a
biological reason: sutures hold the tendon to the bone, but the tendon itself needs roughly
8–12 weeks to grow a durable attachment. Typical protocols — your surgeon’s
instructions always govern — move through four phases:

• Weeks 0–6 — protect the repair. The arm lives in a sling. Therapy
  is passive: pendulum swings and a therapist moving the shoulder through range while the
  cuff muscles stay switched off. Elbow, wrist, and hand exercises keep the rest of the arm
  from stiffening.
• Weeks 6–12 — earn back motion. The sling comes off and
  active-assisted, then active, range of motion begins. Still no lifting — reaching the
  shoulder overhead under its own power is the goal, not carrying anything there.
• Months 3–5 — rebuild strength. Progressive resistance for the cuff
  and the scapular stabilizers, typically starting with bands. This is where the shoulder
  stops feeling fragile.
• Months 5–6 and beyond — return to demand. Job- and sport-specific
  loading. Desk work with the arm protected often resumes far earlier, but overhead and
  heavy-lifting trades commonly need six months or more before the repaired cuff is ready
  for full duty; larger tears take the longer end of the range.

Our physical therapy team runs this progression in-house,
alongside pain management for the early weeks, and we document work restrictions at each phase
so your employer and the insurer see the same plan — see
returning to work after an injury for how
graded duty works. Patients hurt in crashes often face this arc in tandem with another common
crash operation: knee ligament reconstruction after the leg braces against the floorboard. If
that’s part of your picture, the recovery logic is laid out on our
ACL reconstruction page — a different joint, but
the same protect-then-load rehabilitation thinking.

Rotator cuff surgery FAQ

How long does rotator cuff surgery recovery take?

Most patients follow an arc of roughly four to six months: about six weeks in a sling with
passive motion only, motion work through month three, then progressive strengthening. Return to
heavy or overhead work commonly takes six months or more, and large or massive tears can take
longer. Your surgeon’s protocol and your exam findings set the actual pace.

How long will I wear the sling?

Typically four to six weeks, depending on tear size and repair quality. The sling protects
the healing tendon-to-bone attachment during the window when it is weakest; removing it early
to “test” the shoulder is how repairs get re-torn. Therapy still happens during this
phase — it is just passive, with the therapist doing the moving.

Does workers’ comp cover rotator cuff surgery in New York?

Workers’ compensation pays for medically necessary treatment of a work-related shoulder
injury, including repair surgery when clinically indicated, under the Board’s Medical
Treatment Guidelines. Certain procedures require insurer authorization before they are
performed, and the medical record must connect the tear to the work incident. Coverage
determinations are made by the carrier and the Workers’ Compensation Board.

Does No-Fault cover rotator cuff surgery after a car accident?

Medically necessary treatment of crash-related injuries — including surgery and
post-surgical rehab — is payable from basic No-Fault coverage of up to $50,000 per person,
provided the claim was opened with Form NF-2 within 30 days of the accident. The surgery,
imaging, and rehabilitation all draw from that same benefit pool.

Can a rotator cuff tear heal without surgery?

Partial-thickness tears are commonly managed without surgery — therapy, activity
modification, and pain management restore comfortable function for many patients. A
full-thickness tear does not reattach on its own, but not every full-thickness tear requires
repair; some patients regain satisfactory function through rehabilitation. The exam, the MRI,
and your functional demands drive the decision.

When can I go back to work after rotator cuff repair?

It depends on what the job asks of the shoulder. One-armed desk duty may be possible within
weeks, with restrictions documented for your employer. Jobs involving lifting, and especially
overhead work, commonly wait until strengthening is complete — often six months or more. We
update written work restrictions at each rehab phase so duty changes track the medicine.
