The Power of Prehab: Why Strengthening Before Hip and Knee Replacement Surgery is Crucial

Undergoing hip or knee replacement surgery is a significant step towards improving mobility and reducing chronic pain. However, what many people don’t realise is that the journey to recovery doesn’t start post-surgery. It actually begins well before the operation itself. This is where prehabilitation (prehab) plays a crucial role. Prehab is a structured exercise and therapy program designed to strengthen the muscles surrounding the affected joint, enhance flexibility and improve overall function prior to having surgery.

Why Prehab Matters Before Surgery

Research has consistently shown that individuals who engage in prehab prior to joint replacement surgery experience better post-operative outcomes. Strengthening the muscles of the legs including the quadriceps, hamstrings, glutes and calf muscles provides better support for the joint, ultimately facilitating a smoother recovery, reduced post-surgical pain and quicker return to normal activities.

The Benefits of Prehab for Hip and Knee Replacement Patients

1. Improved Muscle Strength
   • Stronger muscles act as a natural brace for the joint, leading to better stability post-surgery.
   • Studies show that patients with higher preoperative muscle strength experience faster functional recovery and improved long-term outcomes.
2. Enhanced Balance and Proprioception
   • Prehab helps train the body’s ability to sense movement and position, reducing the risk of falls post-surgery.
   • Enhanced balance has been linked to greater confidence in mobility and a lower likelihood of complications after surgery.
3. Reduced Post-Surgical Pain and Complications
   • Patients who participated in a structured prehab program often report lower pain scores and require fewer pain medications post-surgery.
   • Strengthening exercises improve circulation, reducing swelling and promote faster healing.

Can Prehab Prevent the Need for Surgery?

Interestingly, an increasing number of patients who commit to a dedicated prehab program find that their symptoms improve to the point where they no longer require surgery. This is particularly true for individuals with moderate arthritis, where improving muscle strength, flexibility and proprioception can significantly reduce pain and restore function.

A 2018 study published in Arthritis Care & Research found that nearly 30% of participants who underwent a targeted prehab program cancelled their scheduled hip or knee replacement surgeries. This was attributed to the substantial reduction in pain levels, increased joint stability, and improved overall mobility. Another study by Rooks et al. (2006) in Osteoarthritis and Cartilage reported that patients who completed a 12-week prehab program experienced a 40-50% reduction in pain, often delaying or avoiding surgery altogether.
