The Right Diet Makes All the Difference: What You Should Eat and Avoid While Recovering from Knee Replacement Surgery

Total Knee Replacement

The first thought you have after undergoing such a life altering procedure like a total knee replacement is having a smooth sailing recovery. There are many successful strategies that work wonders in healing your body such as following your doctors orders and engaging in some knee strengthening exercises. But if you’re looking for another excellent way to have a major impact on your recovery, try turning to what you’re eating. Your body has much to repair from loss of important minerals to cells and tissues which means it needs the right nourishment now more than ever. By acknowledging which vitamins and minerals quickly and efficiently assist in getting your body back to normal, you will fly through your recovery.

To get started, check out these five most essential vitamins and minerals to add to your diet.


This mineral takes an important role in cell regrowth as well as keeping your immunity up so making sure you get your daily amount (about eleven grams for men and eight grams for women) will help make your recovery a breeze. With meat being the highest source, you’ll find at least 5 grams towards your daily goal in beef and oysters, 3 grams in turkey, pork, and veal, and although the levels are much lower, those living the vegetarian life will rejoice knowing nuts and seeds also contain the zinc they need.

Vitamin C.

Going beyond just an immunity boost, Vitamin C is a necessary part of forming cartilage and bone as well as repairing tendons, ligaments, and skin. Consuming your required 75mg-90mg is as simple as adding an array of fruits and vegetables to your meal plan. With food out there containing higher levels of Vitamin C than just your typical glass of orange juice, you can indulge in some great dishes like stuffed roasted red peppers and preparing a strawberry or papaya parfait.


It’s inevitable to lose blood during an operation and that blood loss is also accompanied by low levels of iron. Seeing how this mineral helps combat blood clotting along with avoiding anemia, in most cases your doctor will prescribe a supplement, but you could do more on your behalf by opting for iron-rich food such as spinach, fish, and even cashews.

Vitamin D

Strengthening your knee is a key factor that follows replacement surgery, so why not give your body a vitamin that amplifies bone density along with muscle and tissue regeneration? If you enjoy flounder or codfish, mushrooms, and love eggs for breakfast or mixed into your salad, you’ll find yourself obtaining the right amount of Vitamin D to get the job done.


One of the most important things to add to your diet plan is fiber-rich food. A major complication many people endure after surgery is constipation due to a side effect in their pain killers. To derail any risk of further discomfort, it’s in your best interest to make sure your body is taking in enough whole grain bread, rice, and cereal as well as fiber-packed fruits and vegetables like apples and carrots.

Being aware of the amazing benefits of consuming the right nutrients is only the first step though. It’s important you now acknowledge some foods to take caution with and avoid while you’re recovering from your knee replacement.

Vitamin K.

Although vegetables are a crucial part of any healthy diet, those that are a source of Vitamin K may contribute to blood clotting, which is already a risk factor after surgery. Make it your short-term goal to ditch broccoli, cauliflower, onions, kale, cabbage and any other food that contains this vitamin.


We mentioned earlier how constipation is a culprit in amplifying your pain level which ultimately can place additional stress on your recovering knee. As important as it is to eat food that will help you go, it’s just as important to avoid foods that contribute to constipation such as candy, cake, and other pastries. Furthermore, there’s no nutritional value in these items and with their ability to make you feel full faster, they more often than not take the place of the essential food your body needs to heal.


It isn’t always necessary to completely cut dairy products from your diet, however it can cause constipation for some people because of how difficult it becomes to digest after surgery. Focus on low-fat products like yogurt, skim milk, or cottage cheese and eat these in moderation until you establish whether or not your body can handle dairy, and if not, it’s wise to eliminate it for the time being.


Since you’re avoiding constipation, you might think having a cup of Joe when you roll out of bed or need a quick energy boost is a safe way to go, but drinks high in caffeine could make matters worse by causing diarrhea. Therefore, it’s best to avoid coffee, soda, and other caffeinated drinks for at least a couple of weeks after surgery.


Just in case this was questionable, you cannot kick back with a beer while you watch the game. Alcohol causes blood thinning which slows down the healing process as well as risks bleeding and bruising so avoid it entirely.

As always, before altering your diet, consult your doctor to make sure increasing your vitamin intake won’t affect any medication you might be on or to discuss if you need to go a different route such as taking supplements. But overall, adjusting what you eat and what you avoid is an excellent way to have a fast and successful recovery.

I could barely walk into OBTS six weeks ago. I had very bad lower back and hip pain. The progress has been life changing for me. I always walk out of there with little or no pain. The staff, Laura, Dr Diane, Angie and, of course, Peggy, have taught me so much to keep my pain at bay. I highly recommend this team.

Amazing staff and amazing care. I came in barely able to stand up straight due to a back injury. After 6 weeks, I feel like brand new. Everyone was extremely helpful and easy to work with. Highly recommended!

I am a PTA student that was required 16 hours of observation time. I had the pleasure of completing my hours at this Valpo location. The staff is incredibly friendly. They were quick to make me feel at home. In a way I was sad to leave, but happy to continue on. I hope to eventually work in this field with a work family this caring and knowledgeable about their profession.

My first experience with OBTS was very positive. During the course of my 13 therapy sessions I worked with many different therapists and all of them were professional and competent. They were able to help me effectively control my pain without medication using their therapy program. Unfortunately, they could not get my physical condition back to the same ability as before. However, this is due to the fact that it was later determined by my doctors that I required surgery. I plan on returning to OBTS for my post-op physical therapy and have already scheduled my evaluation appointment. Scheduling seems to be a challenge sometimes but that's probably an indication of their patient's satisfaction and good reviews. Thank you OBTS!

Everyone that worked with me was helpful. I enjoyed watching the staff interact as they worked as they laughed and smiled making me feel that it was fun to exercise. My knee pain is less and I look forward to having the same results with my back.

My wife and I have been coming here for a year. They have wonderful customer service and the treatments were great. I could say that since coming here for treatments, I am now able to walk properly and sleep well at nights. They help you in the best way possible. The people here are great and we definitely recommend it to everyone!

I have read lots of reviews that say "the entire staff of ..." is great, and you know that it is BS.. .. Butt at OBTS that statement is true. The person answering the phone, appointment setting they work around my schedule. It is truly a team concept. Everyone that has work with/on me keeps me focus on getting healthy to play golf.... Even those employees that haven't work with/on me are upbeat, positive and encouraging both their patients and me..... follow up phone calls, positive, hand written notes of encouragement, reminding me to do my homework so I can play golf this year. Great Employees, Great Business!.

I’ve had an incredible experience here at OBTS. In just two and half weeks I’ve seen and felt remarkable results. My hip mobility has improved by 30%. I credit the excellent physical therapists and the deep tissue laser therapy for my gains. I’ve gone from walking with a limp and pain everyday to walking normally and know that I’ll be back to running in the future. Every single person is warm and friendly here. Great place!
