Introduction:

Aquatherapy and Hydrotherapy-Balneotherapy are terms used interchangeably to indicate a modality of treatment performed in an aquatic environment. This page will attempt to assimilate the current literature for incorporating hydrotherapy into conventional rehabilitation of Anterior Cruciate Ligament (ACL) Injury, conservatively or alongside Anterior Cruciate Ligament (ACL) Reconstruction (ACLR).

Outcome measures of ACL rehabilitation:

  • Instability episodes [1]
  • Pain [1]
  • Issues with:
    • Swelling, walking, climbing, stairs, kneeling, squatting, running, lateral motion, cutting, jumping [1]
  • Measures of knee function:
    • Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) [1][2]
    • International Knee Documentation Committee (IKDC) form, Lysholm and Tegner scores[1]
    • Knee Injury and Osteoarthritis Outcome Score (KOOS4) [2]
  • Graft rupture (post-ACLR only) [3]
  • Contralateral ACL injury [3]
  • Lachman and pivot-shift [4]
  • Passive range of motion (knee flexion & extension), muscle strength, thigh circumference (thigh girth, thigh muscle mass, knee joint swelling) [5][6]
  • Active range of motion (knee flexion & extension) [7]
  • 6 minute walk test (6MWT) [7]

Advantages of Hydrotherapy in ACL/R Rehabilitation

In principle:

  • Early weightbearing [7]
  • Postural and gait exercises in a supported environment [8]
  • Water resistance induced muscular conditioning [8]

Outcomes of Hydrotherapy + Conventional Rehabilitation vs. Conventional Rehabilitation Only:

After 2 weeks post-ACLR, patients who underwent 3 weeks of combined hydrotherapy with conventional rehabilitation, had superior outcomes in proprioception, walking, muscle strength in the short and medium term, compared to participants exclusively in conventional rehabilitation programme [9]. Another trial found that ACLR patients placed through 9 weeks of aquatic rehabilitation immediately post-surgery had better clinical parameters in muscle strength and mass circumference, pain, swelling, and range of motion compared to those on land rehabilitation [5].

A smaller case study of 3 subjects demonstrated no risk of harm in utilizing hydrotherapy to accelerate rehabilitation of ACLR [7].

Considerations for ACL hydrotherapy rehabilitation design:

Accelerated Hydrotherapy Programme [7]
Goal: Treatment:
Gait Retraining Gait training
Quadriceps and hamstring strengthening Closed kinetic chain exercises, Open kinematic chain exercises
Strengthening & endurance training Running, Cycling, Deep-water running techniques
Hip and calf maintenance and strengthening Hip exercises and calf raises, kicking and vertical kicking
Balance and proprioception (perturbation protocol) Balance and proprioception exercises
Plyometric training Jumping, running, shuttle runs, side steps with increased speed
Sports-specific rehabilitation Agility exercises making use of a ball
