8.3 Postoperative MSK Rehabilitation and Exercise Prescription

Quick Answer: Postoperative MSK rehab uses the surgical protocol as safety rails and criteria-based progression (pain, swelling, range, control, function) to advance within those rails. Prescribe exercise with FITT clarity. Protect repairs in vulnerable healing windows while preventing stiffness and deconditioning. Know DVT/PE warning signs and escalate urgently. Return to work and sport is graded and demand-matched—not a single calendar green light.

Postoperative musculoskeletal rehabilitation is a high-yield APC Written Assessment theme because it forces integrated reasoning: surgical healing biology, safety precautions, exercise dosing, complications (especially venous thromboembolism), and functional return to work or sport. Entry-level physiotherapists are not expected to invent surgeon-specific graft protocols from memory for every possible operation. They are expected to read and respect the operative precautions, progress using criteria within protocols, prescribe exercise with FITT clarity, recognise DVT red flags, and design graded return plans that match real demands.

Framing the Postoperative Episode

Before loading tissue, establish:

1. What was repaired/replaced/reconstructed? (e.g., rotator cuff repair, ACL reconstruction, total knee arthroplasty, open reduction internal fixation, spinal fusion, Achilles repair)
2. What are the explicit precautions? (range limits, weight-bearing status, sling/brace rules, resisted movement bans, hip precautions if specified)
3. What is the phase goal? (protect repair → restore range → rebuild strength → power/agility → work/sport specificity)
4. What co-morbidities change risk? (diabetes and wound healing, osteoporosis, cardiovascular disease, smoking, obesity, prior DVT)
5. What does the person need to return to? (desk work, nursing shifts, farming, pivoting sport)

If the protocol is unavailable and the patient is unclear, clarify with the surgical team rather than guessing high-risk loads. On MCQs, the safe answer often prioritises protection of a fresh repair over aggressive “no pain no gain” progression.

Protocol-Based vs Criteria-Based Progression

Protocol-based progression

Protocols provide time-based phase structures grounded in tissue healing estimates and surgical experience (e.g., no active abduction against gravity for a period after certain cuff repairs; protected weight-bearing after some osteotomies; brace locked in extension early after some knee procedures). Protocols reduce dangerous variability and communicate shared expectations across the team.

Criteria-based progression

Criteria-based progression advances the patient when clinical milestones are met, not only because a calendar date arrived. Typical criteria domains:

• Pain and irritability acceptable for the next load
• Swelling controlled relative to baseline
• Range of motion sufficient for the task
• Strength and neuromuscular control adequate
• Movement quality (no major compensation that overloads the repair)
• Functional tests appropriate to stage (e.g., straight-leg raise without lag, single-leg stance control, hop testing much later)
• Confidence and understanding of self-management
• No medical red flags

Best practice for exams: use both. Protocols set the outer safety rails (especially early protection windows). Criteria decide whether the person is ready to use the next freedom the protocol allows. A patient at “week 6” with hot effusion, poor quad control, and wound concerns is not automatically ready for the week-6 advanced circuit. Conversely, some protocols allow criteria-accelerated progress when healing and performance are excellent—still within surgical constraints.

Protecting Surgical Repairs

Tissue healing is not complete when the skin looks fine. Tendon-to-bone repairs, ligament grafts, osteotomies, and fusions have vulnerable phases. Early goals often include:

• Control pain and swelling (RICE/POLICE-style principles as appropriate; elevation, compression, load adjustment)
• Protect repair with sling, brace, or weight-bearing rules
• Maintain adjacent joint mobility and general fitness where safe
• Prevent complications: DVT, PE, chest infection in immobile patients, pressure injuries, stiffness beyond expected, muscle inhibition
• Educate on wound care red flags and when to seek help

Examples of protection reasoning (illustrative, not universal protocols):

• Rotator cuff repair: respect passive vs active vs resisted elevation timelines; avoid sudden unexpected loads and heavy overhead lifting early
• ACL reconstruction: graft protection phases; avoid early uncontrolled pivoting; rebuild quad and neuromuscular control before cutting sports
• Total knee arthroplasty: early mobility is usually encouraged to prevent stiffness and thromboembolism, within pain and medical limits—different philosophy from a delicate tendon repair
• Flexor tendon repair (hand): controlled motion protocols are specialised—do not improvise aggressive stretching
• Spinal fusion: respect log-roll and brace rules early; progress walking; avoid premature heavy loaded flexion/rotation extremes per protocol

Exam trap: applying a high-load “athlete ACL week 20” programme to a medically frail post-arthroplasty patient, or applying aggressive early strengthening through a range that the repair protocol forbids.

FITT Principles for Postoperative Exercise Prescription

Vague advice (“move a bit”) fails exams and patients. Use FITT:

Progression logic

1. Establish clean technique at low load
2. Increase volume (reps/sets/time) before large intensity jumps when irritability is high
3. Then increase load/resistance or complexity (unstable surface, speed, dual task) as criteria allow
4. Add work- or sport-specific drills last
5. Monitor 24-hour response: excessive next-day swelling, night pain spike, or wound stress means you overshot

Specificity: desk workers need sitting tolerance and lifting from car boots; nurses need prolonged standing and patient-handling capacity (with occupational health collaboration); footballers need deceleration and change of direction much later than straight-line jogging.

Exercise categories across phases (general map)

• Early: isometrics, protected passive/active-assisted range, circulation exercises, transfers, gait with correct WB status, breathing if post-anaesthesia/immobility
• Mid: active range restoration, progressive resistance in safe planes, balance, aerobic conditioning
• Late: strength symmetry goals, power, agility, plyometrics if appropriate, occupational simulation, sport-specific skill

Always individualise; arthroplasty and fracture fixation pathways differ from multi-strand soft-tissue reconstructions.

DVT Risk Awareness After Orthopaedic Surgery

Venous thromboembolism (DVT/PE) risk rises with major orthopaedic surgery (especially hip and knee arthroplasty and lower-limb trauma), immobility, cancer, prior VTE, oestrogen therapy, obesity, and thrombophilia. Physiotherapists do not replace medical prophylaxis decisions (anticoagulation, mechanical pumps), but they promote early safe mobilisation, encourage prescribed circulation exercises, and recognise red flags.

Clinical warning features (escalate urgently—do not “massage the calf harder”)

• Unilateral calf swelling, tightness, heat, or pain not explained by expected postoperative recovery pattern
• Positive risk context + sudden dyspnoea, chest pain, tachypnoea, haemoptysis, syncope (possible PE—emergency)
• Rapidly worsening limb swelling with colour/temperature change

Actions: stop lower-limb aggressive soft-tissue work on a suspected DVT limb, keep patient safe, urgent medical/ED pathway, document. Do not rely on a single bedside sign as perfect sensitivity; when suspicion is reasonable, escalate.

Progressive Return to Work and Sport

Return is a continuum, not a binary “cleared/not cleared” daydream.

Return to work

• Analyse physical demands: sit, stand, walk, lift, carry, climb, shift length, cognitive load
• Stage duties: reduced hours → restricted duties → full duties
• Use objective markers: lifting capacity practice, walking tolerance, stair performance, pain/swelling control after a simulated workday
• Coordinate with GP, employer, occupational rehab providers as consented
• Address fear-avoidance and workplace factors (yellow flags still matter postoperatively)

Return to sport

• Healing time minimums from protocol are floors, not automatic green lights
• Strength symmetry, hop/test batteries where validated and appropriate, field sport progression (straight line → change of direction → contact)
• Psychological readiness and previous injury history
• Graded exposure to training before competitive match play
• Communicate residual risk honestly; shared decision-making with surgeon for high-risk returns

Australian Setting Patterns

Private practice post ACL reconstruction

Follow surgeon protocol phases; emphasise quad activation early within rules; progress criteria for running and pivoting; educate on graft vulnerability timelines; plan sport-specific late stage; do not clear cutting sport solely because “it has been six months” if criteria fail.

Hospital day-1 total knee arthroplasty

Bed exercises, circulation, sit out, gait with frame as ordered, knee ROM goals per pathway, pain and nausea liaison with nursing, VTE education, discharge planning for home exercise and services.

Workplace rehab after rotator cuff repair

Respect sling and active elevation bans early; maintain lower-limb fitness; staged return with lifting limits; retrain overhead tasks only when strength and protocol allow; coordinate certificates and graded duties.

High-Yield Exam Distinctions

Putting It Together for APC MCQs

1. Know the operation and precautions before loading.
2. Protocols + criteria beat date-only or criteria-without-protection extremes.
3. FITT makes prescriptions exam-ready and clinically usable.
4. Protect repairs in vulnerable healing windows; early mobility still matters for many arthroplasty/trauma pathways.
5. DVT/PE vigilance is non-negotiable after major orthopaedic surgery and immobility.
6. Return to work/sport is progressive, demand-matched, and shared.
7. Escalate wound infection signs, uncontrolled pain, neurovascular change, and VTE features.

Self-check for this chapter

1. Can I contrast protocol vs criteria-based progression with one clinical example?
2. Can I write a FITT prescription for an early and a late postoperative phase?
3. Can I list DVT/PE warning features and the correct escalation response?
4. Can I outline a graded return-to-work plan after a common MSK surgery?
5. Can I explain how osteoporosis (8.1) and amputation (8.2) change postoperative load decisions?

If yes, you have completed the MSK special populations and postoperative care chapter and are ready to apply the same safety-first, criteria-led reasoning in neurology and cardiorespiratory domains.
