Can You Swim With a Torn ACL?

The anterior cruciate ligament (ACL) is a band of connective tissue in the knee, connecting the thigh bone (femur) to the shin bone (tibia). It prevents the tibia from sliding too far forward and controls excessive twisting or hyperextension of the knee joint. ACL tears are common injuries, particularly in sports involving sudden stops, changes in direction, or jumping. Swimming can be a safe and beneficial activity during recovery from such an injury.

Swimming with an ACL Injury

Swimming can be a safe and beneficial activity for individuals with an ACL injury, depending on the tear’s severity, pain levels, and recovery stage. Water exercise is preferred due to its low-impact nature, which reduces stress on the knee. For those managing an ACL injury without surgery or during post-operative rehabilitation, water movements are often less painful than land-based exercises. Always listen to your body and stop any movements that cause pain or instability.

After ACL surgery, healthcare providers advise against immersing the knee in water until incisions have fully healed. Once cleared, gentle aquatic activity can begin. Even with a complete ACL tear, swimming may be possible once acute symptoms like swelling subside and a reasonable range of motion is achieved.

Benefits of Aquatic Exercise for ACL Recovery

Aquatic exercise offers distinct advantages for ACL injury recovery. Water buoyancy reduces the weight-bearing load on the knee, allowing movement with less pain and stress. This reduced impact environment supports improved range of motion and helps restore knee flexibility. The natural resistance of water gently strengthens surrounding muscles, including the quadriceps, hamstrings, and glutes, without overloading the joint.

Water immersion also enhances circulation, promoting healing and reducing swelling. The hydrostatic pressure of water aids in decreasing inflammation and pain perception. Aquatic exercise allows for cardiovascular conditioning, maintaining fitness without the high impact of land-based activities. Many also find psychological benefits from being able to exercise during recovery.

Safe Swimming Practices and Modifications

When swimming with an ACL injury, specific modifications ensure safety and maximize therapeutic benefits. Strokes like the freestyle (front crawl) and backstroke, which primarily use a flutter kick, are safer. The flutter kick involves minimal knee flexion and extension, reducing strain on the ACL. Using a pull buoy between the legs can reduce leg involvement, allowing an upper body workout.

Strokes involving forceful or twisting knee movements, such as the breaststroke or butterfly, should be avoided or modified. The breaststroke kick can place shearing and rotational forces on the knee, aggravating the ACL. Begin slowly, gradually increasing the duration and intensity of swimming sessions. Avoid forceful pushes off pool walls to prevent sudden knee stress.

When to Seek Professional Guidance

Consulting a healthcare professional, such as an orthopedic surgeon or physical therapist, is essential before starting or continuing any exercise program, including swimming, with an ACL injury. These specialists assess the injury’s nature and severity, determining the appropriate recovery stage for aquatic activities. They provide tailored exercise recommendations and a personalized rehabilitation plan considering individual healing progress and goals.

Professional guidance is also important for monitoring progress and adjusting activities. Patients should be aware of red flags indicating a need for immediate medical attention, such as increased pain, persistent swelling, or a feeling of instability or “giving way” in the knee. Adhering to professional advice ensures a safe and effective recovery, minimizing the risk of further injury.
