Recovering from knee surgery is a journey—one that many hope to navigate by simply resting and “letting the body heal.” While rest plays a role, it’s not the full solution. In fact, rest alone may delay your recovery or even lead to further complications.
If you’re hesitant about starting rehabilitation, you’re not alone. This article will gently walk you through why active recovery matters, and how movement—when guided safely by a biokineticist—can transform your healing.
The Truth About Rest and Recovery
After surgery, your body is inflamed, swollen, and vulnerable. Naturally, the first instinct is to rest. It gives your body time to heal, reduces inflammation, and protects the surgical site. But as soon as your surgeon or rehab provider gives the green light, it’s time to start moving.
Why? Because your muscles, joints, and nervous system rely on movement to recover properly. Staying still for too long leads to weakness, stiffness, and poor circulation—making it harder to return to your normal life.
What Rest Does:
- Reduces inflammation
- Allows the surgical site to begin healing
- Helps manage early pain and fatigue
What Rest Alone Doesn’t Do:
- Restore muscle strength
- Rebuild joint stability
- Retrain movement patterns
- Prevent long-term stiffness or atrophy
Without movement, recovery stalls. Your muscles begin to weaken, your joint may stiffen, and the risk of re-injury increases. Rest should be strategic, not indefinite.
What Happens When You Don’t Move
Inactivity after knee surgery can be just as risky as doing too much too soon.
Risks of Prolonged Inactivity:
- Muscle Wasting – Muscles begin to shrink within days of disuse.
- Joint Stiffness – Lack of movement can reduce range of motion and make walking difficult.
- Poor Circulation – Can delay healing and increase the risk of blood clots.
- Loss of Confidence – Avoiding movement often leads to fear, which leads to further inactivity.
Benefits of Early Movement:
- Improves circulation and reduces swelling
- Maintains muscle function
- Keeps the joint mobile
- Builds confidence in your body again
Movement doesn’t mean going for a jog. It means starting with simple, guided actions to help your knee adapt safely.
How Biokinetics Encourages Safe Movement
Biokinetics focuses on healing through movement—backed by science, guided by expertise.
At Nexus Physical Rehab, your programme is designed around your body, your surgery, and your pace. We begin with light, joint-friendly movements to stimulate healing without overloading the knee.
This might include:
- Isometric exercises (contracting muscles without movement)
- Assisted range of motion drills
- Balance and proprioception training
- Progressive loading to restore strength gradually
We never push before your body is ready—but we also don’t let you sit still and hope for the best.

When to Start Active Rehab
Every knee surgery is different, but in general, active rehab can begin within days or weeks—not months—after your operation.
Your surgeon or biokineticist will guide this based on:
- The type of surgery (e.g., ACL reconstruction, meniscus repair)
- Your level of pain and swelling
- Any complications during the operation
- Your personal recovery goals
If pain is severe or swelling persists, your biokineticist will adapt exercises to avoid further irritation. Rehab is not about pushing through pain—it’s about working with your body’s signals.
