Phase I // 0–2 Weeks Post-Op

Acute Protection & Motion Restoration

The earliest post-operative window prioritizes graft protection, effusion control, and the immediate restoration of full passive extension. Quadriceps activation begins on day one — arthrogenic muscle inhibition in this phase is among the strongest predictors of persistent strength asymmetry months later.25,26,27

// Primary Goals
  • Protect graft and surgical repair
  • Minimize effusion, pain, and inflammation
  • Restore full passive and active extension to 0°
  • Achieve at least 90° of knee flexion
  • Re-establish quadriceps activation
  • Normalize patellar mobility
Key Interventions
Clinical
  • Cryotherapy, compression, and elevation per surgeon protocol
  • Early weight-bearing as tolerated if surgically permitted
  • Passive and active-assisted extension to 0°
  • Heel slides progressing toward 90° flexion
  • Patellar mobilizations in all four directions
  • Neuromuscular electrical stimulation paired with quadriceps sets
  • Straight-leg raises once extensor lag is absent
Assessment Focus
Clinical Only
  • Effusion measurement (stroke test or girth)
  • Active and passive ROM documentation
  • Quadriceps lag and active extension capability
  • Gait pattern with assistive device
  • Pain rating during functional tasks

No force-plate or isokinetic testing this phase. Focus remains entirely on clinical recovery markers.

Medical Team Takeaway
Loss of terminal extension in the first two weeks is the single most common avoidable complication of ACLR. Full passive extension equal to the contralateral limb must be achieved before progressing to Phase II — even at the cost of slowing flexion gains. Arthrofibrosis is far harder to reverse than it is to prevent.25
Exit Criteria

Phase I → II Transition

All criteria must be satisfied simultaneously before advancing to Phase II.

Criterion Threshold Notes
Knee Effusion ≤1+ (Modified Stroke Test) Effusion control prerequisite for loading27
Active Knee Flexion ≥120° End of Week 2 target
Passive Knee Extension 0° — symmetric to contralateral Non-negotiable before Phase II
Gait Normalized without assistive device End of Week 2
Pain ≤2/10 with full weight-bearing During functional activities
Straight Leg Raise No extensor lag Quadriceps activation confirmed25,26
Basketball Integration
Phase I — Upper Extremity & Cognitive

No on-court activity. Maintain athletic identity through upper-body and sport-cognitive work that does not stress the knee.

  • Seated two-ball stationary dribbling; ball slaps; fingertip control
  • Stationary chest/bounce passing — seated or standing on contralateral leg
  • Chair-based shooting form work (no jump); wrist/elbow alignment drills
  • Film review, play diagramming, verbal play drawing
  • Ball-tracking and defensive assignment recognition from bench
02
Phase II // 2–6 Weeks Post-Op

Early Strengthening & Neuromuscular Control

With ROM milestones achieved, the focus shifts to gait normalization, closed-chain strengthening, and the reintroduction of proprioceptive demand. Quadriceps atrophy and persistent AMI continue well into this period — aggressive but targeted strengthening is required.25,30

// Primary Goals
  • Achieve full, pain-free extension
  • Achieve flexion greater than 120°
  • Normalize gait without assistive device
  • Initiate closed-chain strengthening
  • Restore static and dynamic balance
  • Begin conditioning via cycling
Strengthening Progression
Bilateral
  • Leg press in limited range (60°–0°)
  • Mini-squats progressing to 45°–60° depth
  • Step-ups as tolerated, low box height
  • Hip abduction, extension, and external rotation work
  • Core and trunk stability progressions
  • Stationary cycling, low resistance, when ROM permits
Submaximal Testing Options
Monitoring
  • Isometric quadriceps strength via handheld or fixed-frame dynamometry at 60°–90° knee flexion
  • Center-of-pressure tracking during quiet standing
  • Weight-shift symmetry on dual force plates
  • Single-leg stance time, eyes open and closed

All testing remains submaximal. Establish baselines, not benchmarks.

Exit Criteria

Phase II → III Transition

All criteria must be satisfied simultaneously before advancing to Phase III. Formal isokinetic testing at 8 weeks is recommended.1,4

Criterion Threshold Notes
Quadriceps LSI (60°/s) ≥50% Isokinetic testing1
Hamstring LSI (180°/s) ≥65% Isokinetic testing1
H:Q Ratio (60°/s) >0.50 Welling et al., 20184
Active Knee ROM 0–130°+ symmetric to contralateral Full active range
Effusion Response No effusion after training ≤trace post-session
Single-Leg Balance >30 s eyes open; >20 s eyes closed Stable surface
Basketball Integration
Phase II — Standing Stationary

As gait normalizes, reintroduce stationary basketball skills that demand trunk control without rotational stress on the knee.

  • Standing stationary dribbling; crossovers (no lateral steps)
  • Stationary shooting form work; free throw release mechanics (jump suppressed)
  • Two-foot stationary jump shot (bilateral load only) — introduce Week 6–7 if Quad LSI >50%
  • Partner passing (standing, bilateral stance) — chest/bounce/overhead variety
  • Resistance band passing; upper body conditioning (battle ropes, medicine ball, pull-ups)
  • Seated or stationary post footwork: pivot on non-operative leg only; drop-step, up-and-under (non-loaded)
03
Phase III // 6–12 Weeks Post-Op

Progressive Strength & Movement Integration

The transition from bilateral to unilateral loading defines this phase. Plyometric training is introduced based on functional capacity, not time alone — bilateral precedes unilateral, low-amplitude before high-amplitude.21,4,28

// Primary Goals
  • Restore bilateral lower-extremity strength
  • Initiate unilateral closed-chain loading
  • Demonstrate clean squat, lunge, and step-down mechanics
  • Build multi-planar hip and trunk control
  • Begin quantifying limb symmetry
  • Prepare tissue for running and plyometric demands
Bilateral Loading
Heavy
  • Back squats and front squats
  • Romanian deadlifts
  • Hip thrusts and glute bridges
  • Bilateral leg press through full ROM
Unilateral Integration
Progressive
  • Split squats and rear-foot elevated split squats
  • Forward and lateral step-downs
  • Single-leg Romanian deadlifts
  • Reverse lunges with rotational variants
Neuromuscular Focus
Control
  • Lateral step-down quality assessment
  • Knee-valgus control drills
  • Trunk stability with rotational resistance
  • Unstable surface progressions
Performance Team Takeaway
Hip and trunk strength deficits — not knee strength alone — drive the dynamic valgus collapse pattern associated with ACL injury and reinjury.20 Hip abductor and external rotator strengthening must be a non-negotiable component of every session in Phase III. A strong quadriceps on a weak hip is still a high-risk knee.
Exit Criteria

Phase III → IV Transition

All criteria must be satisfied simultaneously before advancing to Phase IV. Include vertical jump testing alongside horizontal hop battery.6,7,8,9

Criterion Threshold Notes
Quadriceps LSI (60°/s) ≥70% Isokinetic1,4
Hamstring LSI (180°/s) ≥75% Isokinetic1
H:Q Ratio (60°/s) 0.50–0.80 Welling et al., 20184
Bilateral CMJ Height LSI ≥85% Force plate or MyJump app28
Single-Leg Hop for Distance LSI ≥80% Horizontal hop battery4
Single-Leg Vertical Jump LSI ≥75% Height LSI6
Single-Leg Drop Jump RSI LSI ≥70% Contact time + flight time6,10
Movement Quality Acceptable on all single-leg tasks No knee valgus >5°, no Trendelenburg, no trunk sway9
Effusion Response No effusion after plyometric sessions Post-session monitoring21
Basketball Integration
Phase III — Bilateral Jumping Introduced

Introduce bilateral jumping; begin stationary shooting with jump; no reactive lateral movement yet.

  • Form shooting with bilateral jump (set shot to jump shot); controlled landing; no lateral drift [Stage A]
  • Mikan drill (bilateral take-off, stationary); layup progression both sides [Stage B]
  • Free throw shooting with full jump [Stage A]
  • Spot shooting — stationary, set positions, no cut-and-catch [Stage B]
  • Bilateral jump + catch + shot [Stage B–C]
  • Stationary dribble moves (hesitation, crossover, behind-back) at full speed [Stage A]
  • Three-man passing weave at walking pace — introduce movement [Stage C]
  • Defensive stance + lateral slide (slow, controlled) — short distance, no reactive change [Stage C]
04
Phase IV // 3–6 Months Post-Op

Running, Strength Loading & Low-Level Plyometrics

This is the inflection point of the protocol. Heavy unilateral strength training is paired with the introduction of running and low-amplitude plyometrics. Objective testing — isokinetic and force-plate — becomes central to progression decisions.1,2,3,4,20

// Primary Goals
  • Build high-level bilateral and unilateral strength
  • Reduce limb symmetry deficits to less than 20–30%
  • Complete a graded running progression
  • Demonstrate quality landing mechanics
  • Tolerate low-level plyometric load
  • Establish baseline force-plate jump data
// Quad LSI Target
≥70–80%
Minimum isokinetic symmetry before advancing plyometric and COD progressions
// Test Speeds
60°/s
Plus 180°/s and 300°/s to capture functional velocity profile
// Jump Asymmetry
<15%
CMJ interlimb asymmetry on initial bilateral force-plate testing
// Running Start
~3 mo
Walk-jog intervals on level surface once criteria met
Isokinetic Testing
Quantitative

From 3–4 months onward, introduce submaximal-to-maximal isokinetic testing at multiple velocities. Test quadriceps and hamstring peak torque, evaluate torque curves, and calculate limb symmetry index. Use these numbers to dictate progression — not to confirm what you hope is true.1,4

  • 60°/s for maximal strength quality
  • 180°/s and 300°/s for functional velocity
  • Document H:Q ratio bilaterally
  • Track torque curve symmetry, not just peak values
Force-Plate Testing
Baseline

Initiate bilateral countermovement jump testing at increasing intensity. Use this phase to establish baseline force-plate metrics and identify early asymmetries before advanced plyometric loading.20,28

  • Bilateral CMJ with full force-time tracing
  • Isometric mid-thigh pull for total force capacity
  • Submaximal in-place hop quality screen
  • Single-leg squat control assessment
Exit Criteria

Phase IV → V Transition

All criteria must be satisfied simultaneously before advancing to Phase V. Begin ACL-RSI monitoring at this transition.4,12,14

Criterion Threshold Notes
Quadriceps LSI (60°/s) ≥80% Isokinetic1,4
Hamstring LSI (180°/s) ≥85% Isokinetic1
Quadriceps LSI (300°/s) ≥85% Sports-speed angular velocity4
Single-Leg Hop for Distance LSI ≥85% Horizontal hop4
Single-Leg Vertical Jump LSI ≥80% Height LSI6
Single-Leg Drop Jump RSI LSI ≥78% Reactive strength index6,10
Continuous Running 20+ minutes without pain or effusion Return-to-running completion1,2,3
Planned 90° Cut Mechanics Acceptable No knee valgus, no trunk lean
ACL-RSI ≥40 Begin psychological readiness monitoring4,18
Load Management
Target an Acute:Chronic Workload Ratio (ACWR) of 0.8–1.3 during the running and agility phase.29 Weekly running volume increases should not exceed 10–20%. Youth basketball players injured during a season had high acute loads against low chronic loads — specifically a low 3–4 week cumulative jump count before injury. Build the chronic base before introducing load spikes.
Basketball Integration
Phase IV — Linear Movement Introduced

Return to controlled on-court activity. Linear basketball movement resumes — cutting, pivoting at speed, and reactive defensive work remain off the table.

  • Dribble straight-line sprint (70–80%) — no cuts
  • Layup from straight-line approach, both sides
  • V-cut → catch → jump shot (unguarded), 75% intensity
  • L-cut → catch → shot
  • Spot shooting off 45° jog
  • Dribble into 45° pull-up jumper (planned, no reactive defender)
  • Weave dribble through cones (ball-handling under movement stress)
  • 3-on-0 walk-through of offensive sets
  • Partner defensive slide (planned, no reactive)
  • Pick-and-roll read (unguarded)

Coaching emphasis on every rep: increased hip and knee flexion at landing, symmetrical foot placement, and complete avoidance of dynamic valgus.9,20

05
Phase V // 6–9+ Months Post-Op

Advanced Plyometrics, COD & On-Court Integration

High-amplitude plyometrics, multi-directional change of direction, and basketball-specific movement integration converge in this phase. Position-specific load demands — sprint frequency, cutting volume, and jump count — must guide drill selection and progression.31,32,33

// Primary Goals
  • Achieve high-level strength with minimal asymmetry
  • Progress from bilateral to unilateral plyometrics
  • Develop reactive change-of-direction capacity
  • Build eccentric strength and deceleration control
  • Integrate sport-specific injury-pattern retraining
  • Achieve psychological readiness benchmarks
// Quad LSI
≥90%
Minimum isokinetic symmetry, particularly at 60°/s
// Hop & Jump Battery
≥90%
Horizontal hops plus SLVJ height ≥90% and SLDJ RSI ≥85% LSI
// Force-Plate Asymmetry
<10%
Peak force, impulse, eccentric RFD, and landing force on bilateral CMJ
// ACL-RSI
≥56
≥65 preferred before competitive game clearance4,14
Plyometric Progression
Advanced
  • Bilateral to unilateral CMJ variants
  • Drop jumps with strict landing quality criteria
  • Lateral and rotational bounds
  • Repeated single-leg hop testing
  • Reactive plyometric tasks with cognitive load
Change of Direction
Multi-Plane
  • 45° planned cuts, progressing to 90°
  • Pre-planned to reactive COD sequencing
  • Deceleration mechanics with technical focus
  • Nordic hamstrings and eccentric quad loading
  • Sport-pattern integration (dribble-to-cut, catch-to-cut)
Critical Insight — Vertical Jump Testing
Horizontal hop LSI can reach 97% while knee work symmetry is only 69%, as the hip compensates for ongoing quadriceps deficiency.7 Single-leg vertical jump (SLVJ) height LSI target ≥90% and single-leg drop jump (SLDJ) RSI LSI target ≥85% detect residual knee deficits that horizontal hop tests miss.6,8,10 Movement quality must be assessed independently — hop LSI and movement quality are not correlated.9
ACL-RSI

Psychological Readiness Thresholds

First formal ACL-RSI at Week 12; monthly reassessment through RTS. Full battery at 6 and 9 months.4,14,18

Score Clinical Meaning Action
<40 High fear of reinjury Psychology intervention before advancing
40–55 Partial readiness Continue; reassess monthly
≥56 Minimum RTS clearance Welling et al., 20184
≥65 Target for competitive game clearance Inoue et al., 202314
Paradox Warning
Higher ACL-RSI scores at 3 months post-ACLR are associated with higher second injury risk, likely due to premature confidence-driven return.12,13 High psychological readiness is necessary but NOT sufficient. It must be paired with objective physical criteria. Do not advance an athlete who meets ACL-RSI ≥56 but has not yet met strength or hop criteria.
Basketball Integration
Phase V — Sub-Phases A–C

Sub-Phase A — Months 6–7 (Unguarded Skill Work):

  • Full-speed layup series: both sides, 1-foot and 2-foot take-off, 80–90%
  • Mikan drill at full speed; continuous alternating layups
  • Spot shooting off planned cuts (V, L, curl, flare) — catch-and-shoot
  • Wing drive series: drive right/left to basket; pull-up or finish
  • Ball-screen actions (PnR/PnP) unguarded
  • Post entry + counter moves: drop step, up-and-under, hook — bilateral
  • 1-on-0 full-court sprint + layup

Sub-Phase B — Months 7–8 (Controlled Contact):

  • 2-on-0, 3-on-0 offensive sets (multi-player, choreographed)
  • 1-on-1 limited contact (offensive player has ball; defender shadows/token defense)
  • Shell drill (5-on-0 defensive movement patterns)
  • 3-on-2 / 2-on-1 (outnumbered drills, controlled pace)
  • Sprint-cut-receive-shoot (full-speed cuts off screen)
  • Transition sprints: full-court transition runs, finish at rim

Sub-Phase C — Months 8–9 (Team Integration):

  • 5-on-5 half-court (controlled; no press, structured sets; coach-moderated contact)
  • 5-on-5 walk-through → progressive to full-speed
  • Position-specific scrimmage with contact permitted; clinician monitors workload
  • Late-game / high-pressure situation simulation
06
Phase VI // 9–12+ Months Post-Op

Return to Sport & Performance Optimization

RTS clearance is an integrated decision — not a single test result, not a calendar date, and not a single clinician's judgment. Each additional month of delay in returning to pivoting sport reduces reinjury risk by approximately 51% (Grindem et al., 2016), and athletes returning before 9 months carry a 7-fold higher new injury rate (Beischer et al., 2020).16,17

Critical: High Function ≠ Safe Return
Athletes with greater knee extension symmetry at 6 months, and higher quadriceps symmetry in those returning before 8 months, have HIGHER reinjury probability — not lower (Werner et al., 2021, J Athl Train, PMC9020598).19 Passing all functional benchmarks before 9 months is a risk signal, not a clearance signal. The 9-month minimum is non-negotiable.
RTS Criteria

Integrated Return-to-Sport Clearance

No single criterion clears an athlete. All of the following must be met simultaneously before unrestricted basketball competition. Falling short on one element does not equal "almost ready" — it equals incomplete restoration.4,5

Domain Threshold Notes
Time from Surgery ≥9 months Biological graft maturation minimum16,17
Quadriceps LSI (60°/s) ≥90%, prefer ≥95% Isokinetic testing4

Movement Quality Acceptable on all hop, cutting, and deceleration tasks Assessed independently of LSI9,20
ACL-RSI ≥56 minimum; ≥65 preferred Competitive game clearance4,14,18
Non-Negotiable
An athlete meeting strength, hop, and force-plate criteria but scoring low on ACL-RSI is not cleared. Psychological readiness predicts both return to pre-injury level and secondary injury risk independently of physical capacity.4,12,13,14 Graded exposure, sport psychology referral, and additional time at the controlled-practice level are indicated.
Graded RTS Progression Post-Clearance
Phase VI

Formal clearance is not the end of the protocol — it is the start of a graded return to competition. Athletes do not move directly from clinic testing to full minutes.

  • Small-sided games and non-contact drills with monitored intensity
  • Controlled full practice with restricted minutes and tracked load
  • Unrestricted practice once practice tolerance is established
  • Monitored competitive minutes with progressive ramp
  • Position-specific conditioning and role-based demand exposure
  • Ongoing force-plate monitoring during high-demand microcycles

Protocol Principles

// 06 Core Principles
01
Time alone does not clear an athlete. Grindem et al. (2016) demonstrated each additional month of delay in returning to pivoting sport reduces reinjury risk by ~51%. Beischer et al. (2020) found athletes returning before 9 months had a 7-fold higher new injury rate.16,17 Time is a floor, not a finish line.
02
Criteria-based progression must be integrated. Strength, hop performance, force-plate metrics, biomechanical quality, and psychological readiness each measure different qualities. Meeting one does not substitute for another.4,5,6,9
03
Hop tests alone undersell deficits. Horizontal hop LSI can reach 97% while knee work symmetry is only 69%, as the hip compensates for ongoing quadriceps deficiency.7 Single-leg vertical jump and drop jump RSI detect residual knee deficits that horizontal hop tests miss.6,8,10 Movement quality must be assessed independently.9
04
Basketball injury patterns must be rehearsed. Basketball-specific movement patterns — cutting, deceleration, repeated jumping, and reactive decision-making — must be progressively loaded rather than relying on generic athletic tasks alone.31,32,33
05
Hip and trunk control protect the knee. Dynamic valgus and lateral trunk lean are mechanically driven by hip and trunk weakness, not knee weakness.20,24 Proximal control must be programmed across every phase.
06
Psychological readiness is a clearance criterion. ACL-RSI ≥56 is the minimum RTS threshold; ≥65 is preferred before competitive game clearance.4,14 Higher ACL-RSI at 3 months paradoxically predicts higher reinjury risk — confidence without physical readiness is dangerous.12,13
