# Managing Orthopedic Rehabilitation

Structures post-surgical and musculoskeletal injury rehabilitation using phase-based protocols with objective progression criteria, tissue healing timelines, and return-to-activity/sport testing. Covers major procedures including ACL reconstruction, total joint arthroplasty, rotator cuff repair, and fracture management.

## Why This Skill Exists

Orthopedic rehabilitation follows tissue-healing biology and surgeon-specified protocols. Premature progression risks re-injury or surgical failure; overly conservative treatment causes unnecessary stiffness, atrophy, and prolonged disability. Each surgical procedure has evidence-based rehabilitation timelines that dictate when motion, loading, and return-to-activity are safe. Documentation must reference the specific protocol, demonstrate adherence to weight-bearing and ROM restrictions, and track objective progression criteria. Payer audits scrutinize visit counts against diagnosis-specific norms. Legal proceedings require evidence that the rehabilitation followed the standard of care for the specific procedure. This skill systematizes protocol adherence and milestone tracking.

## Checkpoint A — Intake Verification

Before beginning orthopedic rehabilitation, confirm:

**Required clinical questions:**
- What is the surgical procedure or injury diagnosis (specific: "L ACL reconstruction with bone-patellar tendon-bone autograft" not just "knee surgery")?
- What is the date of surgery or injury?
- What are the surgeon's specific restrictions (weight-bearing status, ROM limits, brace requirements, precautions)?
- What was the intraoperative finding or fixation quality (stable/unstable, concomitant procedures such as meniscal repair, labral repair)?
- What is the patient's pre-injury activity level and return-to-activity goals?
- Are there comorbidities affecting healing (diabetes, smoking, immunosuppression, osteoporosis)?

**Required documents:**
- Operative report with procedure details, graft type, fixation method, and concomitant procedures
- Surgeon's post-operative rehabilitation protocol (specific to the practice if available)
- Post-operative orders with weight-bearing status, brace settings, and restrictions
- Pre-operative imaging and functional status if available
- Insurance authorization with approved visit count

## Step 1 — Map the Rehabilitation to Tissue Healing Phases

All orthopedic rehab aligns with biological healing:

| Phase | Timeframe (approximate) | Biology | Rehab Focus |
|---|---|---|---|
| Phase I — Maximum Protection | Weeks 0-2 (soft tissue) / 0-6 (bone) | Inflammatory phase, hemostasis, cellular recruitment | Pain/edema control, protected ROM within limits, muscle activation |
| Phase II — Moderate Protection | Weeks 2-6 (soft tissue) / 6-12 (bone) | Proliferative phase, collagen deposition, callus formation | Progressive ROM to full, gentle strengthening, proprioception initiation |
| Phase III — Minimum Protection | Weeks 6-12 (soft tissue) / 12-24 (bone) | Remodeling begins, tissue maturation | Full ROM, progressive strengthening, functional activity |
| Phase IV — Return to Activity | Weeks 12+ (soft tissue) / 24+ (bone) | Mature remodeling, near-normal tissue properties | Sport-specific training, plyometrics, return-to-sport testing |

**Adjust timelines for:**
- Concomitant procedures (meniscal repair adds 4-6 weeks of restricted WB/ROM)
- Patient factors (age, diabetes, smoking delay healing by 30-50%)
- Revision surgery (more conservative timelines than primary)
- Biological augmentation (PRP, stem cells — follow surgeon protocol)

## Step 2 — Implement Procedure-Specific Protocol

**ACL reconstruction (example: bone-patellar tendon-bone autograft):**
- Weeks 0-2: WBAT with brace locked in extension for ambulation, ROM 0-90 degrees, quad sets, SLR
- Weeks 2-6: Full ROM target by week 6, closed-chain exercises (mini-squats, leg press), patellar mobilization
- Weeks 6-12: Progressive resistance, stationary bike, proprioceptive training
- Weeks 12-16: Running program initiation if quad strength ≥70% contralateral
- Months 6-9: Return-to-sport testing battery

**Total knee arthroplasty:**
- Day 0-1: WBAT with walker, CPM if ordered, ankle pumps, quad sets, SLR
- Weeks 1-6: Progressive ROM (goal: 0-120 degrees by week 6), stair training, gait training
- Weeks 6-12: Strengthening progression, balance training, community ambulation
- Months 3-6: Full return to low-impact activities; discharge when goals met

**Rotator cuff repair:**
- Weeks 0-6: Sling immobilization, passive ROM only (pendulums, table slides), no active shoulder motion
- Weeks 6-10: Active-assisted ROM progressing to active ROM
- Weeks 10-14: Light strengthening (isometric then isotonic)
- Months 4-6: Progressive resistance, functional overhead activities
- Note: Large/massive tears may require extended immobilization per surgeon

**Total hip arthroplasty (posterior approach):**
- Precautions: No hip flexion >90 degrees, no adduction past midline, no internal rotation for 6-12 weeks
- WBAT with walker/cane unless cemented vs. uncemented requires modification
- Progressive gait training, stair training, functional mobility
- Anterior approach: typically fewer precautions, faster protocol

## Step 3 — Track Objective Milestones at Each Phase Transition

Before advancing phases, document that criteria are met:

**Phase I → Phase II transition criteria:**
- Pain ≤4/10 at rest
- Wound healing progressing without signs of infection
- ROM at expected level per protocol timeline
- Quad activation present (able to perform SLR without extensor lag)
- Weight-bearing status achieved as ordered

**Phase II → Phase III transition criteria:**
- Full passive ROM or within 10 degrees of contralateral
- MMT ≥3+/5 for surgical limb primary movers
- Normalized gait pattern with appropriate device
- No effusion increase with current activity level

**Phase III → Phase IV transition criteria:**
- Full ROM equal to contralateral
- Strength ≥80% of contralateral by dynamometry
- Single leg balance ≥30 seconds without loss of balance
- Functional movement quality satisfactory (no compensatory patterns)

## Step 4 — Perform Return-to-Sport/Activity Testing

For patients returning to athletics or demanding physical activity:

**Standard return-to-sport battery (ACL example):**
- Isokinetic quadriceps/hamstring strength: Limb Symmetry Index (LSI) ≥90%
- Single-leg hop tests (4 hop tests): LSI ≥90% on each
  - Single hop for distance
  - Triple hop for distance
  - Crossover hop for distance
  - 6-meter timed hop
- Y-Balance Test: composite score within 4 cm of uninvolved limb
- Functional movement screen (FMS) score ≥14 with no asymmetries
- Sport-specific agility testing (T-test, pro agility)
- Patient-reported outcome: ACL-RSI (ACL Return to Sport after Injury) scale ≥56/100 for psychological readiness

**Clearance criteria documentation:**
- All quantitative test results with pass/fail per threshold
- Surgeon clearance obtained (document date and communication)
- Patient education on ongoing injury prevention program
- Graduated return-to-play schedule (not immediate full participation)

## Step 5 — Document Visit Utilization Against Expected Norms

Track total visits and compare to diagnosis-specific benchmarks:

| Procedure | Typical Visit Range | Expected Duration |
|---|---|---|
| ACL reconstruction | 24-36 visits | 6-9 months |
| Total knee arthroplasty | 12-20 visits | 6-12 weeks |
| Total hip arthroplasty | 8-16 visits | 6-12 weeks |
| Rotator cuff repair | 20-30 visits | 4-6 months |
| Ankle ORIF | 12-20 visits | 8-12 weeks |
| Lumbar fusion | 16-24 visits | 3-6 months |

Document clinical justification when visits exceed expected ranges: comorbidity-related delays, complications, concomitant procedures.

## Guidelines

- Always obtain and read the operative report — protocol selection depends on graft type, fixation, and concomitant procedures
- Never advance rehabilitation phases based solely on time; progression requires meeting objective criteria
- Surgeon preferences may differ from published protocols — document which protocol is being followed and any modifications
- Post-operative complications (DVT, infection, hardware failure) require immediate physician notification and documentation
- CPM (continuous passive motion) use is declining in evidence — follow surgeon preference but document rationale
- Effusion monitoring is essential: persistent effusion indicates the tissue is being overloaded
- Cryotherapy is evidence-based for acute post-operative pain and edema — document use and response
- For workers compensation cases, document work-related restrictions at each visit using DOL physical demand categories
- Scar mobilization should begin once wound is fully closed and sutures/staples removed
- Return-to-sport decisions are shared between surgeon, therapist, and patient — document the conversation and decision rationale
