Nutrition for Knee Health and Injury Prevention

Dr. Pablo Gelber, MD, discusses nutrition as a foundational element for overall health, which indirectly supports knee injury prevention. He states there is no single "correct" diet, but rather any nutritional habit that makes a person feel good and provides a balanced intake of macronutrients is beneficial. A diet with good sources of protein for muscle repair, carbohydrates for energy, and healthy fats is essential for maintaining the strength and resilience of the tissues surrounding the knee joint.

The Problem with Isolated Quadriceps Strengthening

Dr. Gelber challenges a common piece of advice in knee care: the singular focus on quadriceps strengthening. He explains that exclusively working the quads can create a significant muscular imbalance in the lower limbs. This imbalance can alter biomechanics and potentially increase stress on knee structures like the meniscus and ligaments, rather than protecting them. This counterintuitive insight from Dr. Pablo Gelber, MD, shifts the focus from a single muscle group to the entire kinetic chain.

The Critical Importance of Hip and Core Strengthening

For true knee injury prevention, Dr. Pablo Gelber, MD, emphasizes that strengthening must extend to the hips and core. A strong core and hip musculature provide proximal stability for distal mobility, meaning a stable pelvis and hip joint allow for safer and more controlled movement at the knee. This holistic approach is vital not only for knee conditioning but also for preventing other issues, such as pubic-related pain, that can arise from a weak core.

Benefits of Functional Workouts for Knee Stability

Dr. Pablo Gelber, MD, strongly recommends functional strengthening over machine-based isolation exercises. He points out that traditional gym machines like the leg press or leg extension machine train movement in a single, artificial plane. Functional workouts, which involve multi-planar movements and often use bodyweight or free weights, are far more effective because they directly relate to the demands of normal life and athletic activities, thereby better preparing the knee for real-world stresses.

Knee Injury Prevention for Runners and Athletes

This holistic and functional approach is particularly crucial for athletes. Dr. Gelber uses the example of runners, many of whom never perform core exercises, which he describes as "mandatory." The dynamic, multi-directional movements in sports like football, basketball, and volleyball have little in common with the fixed path of a machine. Training functionally ensures the body is prepared for the specific loads and movements encountered in sport, which is the key to preventing non-contact knee injuries.

A Holistic Approach to Knee Rehabilitation

This philosophy extends to recovery from both conservative treatment and post-surgical rehabilitation. A rehabilitation program that incorporates core stability, hip strengthening, and functional movement patterns will lead to a more complete recovery and reduce the risk of re-injury. By addressing the body as an interconnected system, patients can recover faster and return to activity with greater confidence and resilience, a point Dr. Gelber makes clear in his discussion with Dr. Anton Titov, MD.

Full Transcript

Dr. Anton Titov, MD: What kind of exercise, lifestyle, or perhaps nutrition factors can help people to avoid knee injury? What can reduce the risk of knee injury? Let’s assume a person is doing everything else correctly. In particular, how to prevent knee meniscus, knee ligament injury, and patellofemoral joint injuries? How to recover faster from conservative or surgical knee injury treatment? Are there factors that can help people to avoid knee injury? Lifestyle and nutritional factors.

Dr. Pablo Gelber, MD: Yeah, the two knee injury prevention factors that you have commented on. One is nutrition factors in reducing the risks of a knee injury. It’s also a huge topic to answer. I don’t believe there is only one way to be nutritionally healthy. There are different ways to obtain that.

I think any nutrition habits that make the person feel good are good enough. It is important to have a good source of protein, carbohydrates, and fat. All this should be good enough.

But on the other hand, you asked me what kind of exercise the patient can perform to decrease the knee injury. I don’t believe in most of the very commonly heard advice that people say. They say, “work on your quads,” “your quads have to work.” I don’t believe that because if you only focus on the quads, you will produce an imbalance of your lower limb muscles.

I believe, as we were saying before, in a holistic way to prevent knee injuries. You need not only to strengthen your muscles, quads, and back part of the thigh. But also, it is very, very, very important to do hip strengthening and core strengthening.

It’s true even for running. I know a lot of runners who never perform any kind of core exercises. This is mandatory to do. It’s not only for the improvement of knee conditioning. It is also to prevent any kind of pubic problem.

I would recommend doing functional strengthening. It is not about doing a typical one-plane exercise at the gym, like the squat machine or exercising on a calf machine. It is much better if you perform functional workout because that is more related to what you would do in normal life.

You might train artificially, as most gym machine exercises are done. Then you won’t prevent any kind of knee injury that you risk when you perform freestyle exercises—for example, running, football, volleyball, rugby, or basketball. Because the way you move in those sports has nothing to do with what you are doing in your machine-based workout.

It is very helpful to know that!
