Matrix-induced autologous cartilage implantation (MACI) is a promising treatment for patellar arthritis, particularly for restoring cartilage. Let's break down your questions and provide clear guidance.
Main Points:
- True Cartilage Use: MACI involves using genuine cartilage cells (chondrocytes) that are harvested from your own body.
- Objective of Treatment: While MACI aims to restore function and provide some relief similar to natural cartilage, it may not completely return the knee to its original state.
- Pre-Procedure Considerations: Understanding the necessary steps before moving forward with treatment is crucial.
Explanation:
-
How MACI Works: In MACI, cartilage cells are taken from a small area of healthy cartilage and are grown in a laboratory on a scaffold (matrix). This matrix helps the cells to grow and ultimately be implanted back into the damaged area of your knee. The goal is to create a layer of cartilage that can help distribute weight and reduce pain, improving function.
-
Restoration Goals: While the goal is to restore some level of cartilage function, the newly engineered cartilage may not behave exactly like your original cartilage. However, many patients experience significant pain relief and improved mobility after the procedure.
Next Steps:
-
Research and Education:
- Learn more about MACI by reviewing trusted medical sources or patient testimonials regarding their experiences.
-
Consultation with a Specialist:
- Discuss your condition with an orthopedic surgeon specializing in knee treatments. Prepare specific questions about your diagnosis, MACI, and alternative treatments.
-
Pre-Surgery Evaluation:
- Undergo examinations (such as MRI scans) to assess the severity of your arthritis and ensure you're a suitable candidate for MACI.
- Discuss whether lifestyle modifications (like weight management and physical therapy) can be beneficial prior to undergoing the procedure.
-
Support Network:
- Talk to others who have undergone similar procedures to understand the recovery process and outcomes. Connecting with a support group can provide encouragement.
-
Behavioral & Lifestyle Changes:
- Explore low-impact exercises that strengthen the muscles around the knee without putting undue stress on the joint.
By following these steps, you can make a well-informed decision while preparing for the potential benefits of MACI for your patellar arthritis. If you have any further questions or need more information on specific aspects, feel free to ask!

Concerns About My Mother's Emphasis on Cutting Carbs
Every day, my mother finds a new justification for eliminating carbohydrates from her diet. Today, she discussed a so-called "ketogenic diet." This approach often involves limiting carb intake to below 50 grams each day. I explained to her that for optimal health, the body actually requires a minimum of 130 grams of carbohydrates. She's become engrossed in videos from someone referred to as "Dr. Boz," claiming that cutting out sugars and carbs entirely is essential for her to access ketones by removing glucose from her system. Despite my insistence that her body primarily relies on glucose for energy, she remains unconvinced. Is this diet truly healthy? Am I overly concerned, or should I just cease our debates on the topic? For context, she is at a perfectly normal weight (147 lbs and 5 feet 7 inches tall).
Experiencing Unexpected Skin Pain Without Visible Cause
I have consulted my physician regarding my unusual symptoms, but she was unable to provide a clear diagnosis. The only possibility she mentioned was fibromyalgia, which she believes may not apply to me due to my age. Although blood tests were performed, everything appeared normal. I'm a 29-year-old female dealing with obesity and have been managing my weight for a long time, currently with the help of Wegovy. I was a smoker and vaper for several years but have quit these habits since last year. Occasionally, when I touch, scratch, or bump against areas like my shoulders, upper arms, thighs, and lower back, I experience severe pain beneath my skin that doesn’t correlate with any visible injury. There are no marks or rashes left behind afterwards. The sensation resembles that of a bruise or the sharp pain felt when one strikes their hip. There are moments when the pain is so intense that I involuntarily cry out, but it only lasts for a brief period of 5 to 10 seconds. The occurrences are erratic; some days I can touch or scratch these areas without any discomfort, while other days, the pain strikes unexpectedly. This has been a recurring issue for approximately five years now. I'm reaching out to see if anyone might have insights or suggestions about what this could indicate.
Dealing with Loperamide-Induced Constipation: Seeking Solutions
Warning: This discussion involves digestive health topics. I’m a 24-year-old woman, standing at 5’5” and weighing around 140 pounds. I don’t smoke and have been diagnosed with anxiety and depression. Recently, I was experiencing severe anxiety and dehydration due to some intense diarrhea, which prompted my doctor to prescribe loperamide. I took the initial dose two days ago and haven’t needed additional doses since then. However, now I find myself struggling with constipation and have yet to have a bowel movement. I’ve just started passing some gas, but still no stool. My anxiety persists, which is causing muscle tension and making it hard for me to breathe easily. To be honest, my eating and sleeping habits have been off due to the anxiety. My diet mainly consists of fruits, bread, rice crackers, beans, and jerky, and I only had a proper meal (tacos) today. I’ve also been trying melatonin for sleep, which is something new for me. I started with a 3 mg dose the first night, and I felt incredibly groggy the next day, so I reduced it to 1.5 mg the following night. I took both the loperamide and melatonin on the same evening. Unfortunately, my doctor is unreachable since the health clinic is closed over the weekend, leaving me without guidance. I’ve begun to experience some mild abdominal discomfort, but I think a proper bowel movement would alleviate that. I prefer to avoid over-the-counter remedies, as I’m concerned about jeopardizing my hydration, which has been quite the struggle. I’m wondering if anyone has suggestions for foods that might help, any stretches that could encourage movement, or if I should simply try to relax.
Seeking Answers for Digestive Distress: Recommended Tests and Advice
I am a 34-year-old Caucasian female, standing at 165 centimeters tall and weighing 78 kilograms. On a daily basis, I take several medications: Prestance (5/5), Aerius, a hormonal contraceptive vaginal ring, and magnesium bisglycinate (365 mg). Occasionally, I also use Lexaurin (bromazepam) at a dosage of 0.75 mg every two or three weeks, primarily for anxiety and sleep disturbances, though I have not taken it in the last three weeks. Previously, I underwent multiple tests. Initial blood tests indicated a slight increase in amylase levels, which led to an abdominal ultrasound, yet nothing abnormal was detected. Both flexible sigmoidoscopy and a subsequent abdominal ultrasound were performed, revealing only hemorrhoids and an anal fissure. Throughout my life, I’ve grappled with digestive issues. Since childhood, I dealt with constipation, which ultimately resulted in hemorrhoids and my first anal fissure. To address this, I became conscious of my diet and utilized osmotic laxatives, which significantly improved my situation for many years, allowing me to have regular bowel movements without bleeding. However, approximately one year ago, I began experiencing unexpected episodes of diarrhea that can last between a couple of days to a week at a time. Mornings are particularly challenging, as I often experience loose stools, which eventually stabilize later in the day. During these episodes, I feel continually fatigued; after waking up, all I want is to return to bed, and merely completing my workday feels incredibly taxing. I also suffer from persistent nausea without vomiting, and this typically follows a pattern of ten days of normal or firmer stools followed by three days of diarrhea. Thankfully, I managed to avoid any diarrhea for over two months and even found myself needing to use Miralax occasionally. However, this past Wednesday, I awoke to an upset stomach once again. My meals consist of homemade food, which I ensure is not overly greasy or heavy, avoiding fast food and excessive sweets altogether. My overall daily functioning is severely impacted by the fatigue and frequent headaches I experience. Although I don’t encounter much abdominal pain, I do feel cramping in the lower central abdomen along with considerable gas and rumbling. I have scheduled an appointment with my general practitioner for Monday, though I find her approach somewhat passive; she tends to follow my requests rather than take the lead. What diagnostic tests should I consider requesting? While I am open to the possibility of upper endoscopy, a full colonoscopy seems daunting due to my anal fissure. I would greatly appreciate any insights regarding what might be happening. I understand it’s difficult to provide specific answers, but any guidance would be immensely appreciated!
Could This Be IBS or Something Else?
Greetings! I’m a 27-year-old male, standing at 172 cm and of European descent, currently using Iqos. My medical troubles began roughly four months ago, around October 5, 2025. Initially, I experienced intense back pain lasting for two days, which I recognized as kidney stone pain. To alleviate this discomfort, I took NSAIDs, predominantly Metamizole-Natrium. Afterward, I visited urgent care, where I was given Diclofenac and Monural, an antibiotic for urinary tract infections. I took one of each at night. **A couple of days later, I started experiencing several troubling symptoms:** - Frequent diarrhea (4-5 times a day, often watery) - Significant gas and belching - Persistent nausea that greeted me each morning, sometimes relieved by eating - A general sense of malaise - A loss of 5 kg (I dropped from 63 kg) because I lacked appetite, especially under stress. These symptoms developed quickly and intensified through October, fluctuating over time. Blood tests showed no abnormalities, with normal CRP levels. Then in November, I underwent a colonoscopy and gastroscopy. - I had three very small erosions, about 1-2 mm, in the terminal ileum, but no signs of inflammation. Histology revealed no pathological issues, all was well. - There was one small erosion in the sigmoid colon, with minor inflammation around it. Histological findings indicated small infiltration in the lamina propria but no chronic signs, leading to a diagnosis suggesting a high likelihood of infection. - The areas were healing, with fibrin present. The rest of my colon appeared healthy. The doctor attributed the ulcers to NSAID-induced damage. I was later diagnosed with LA-A GERD. Due to my anxiety about health, I spent the month consumed by fears of complications such as colon cancer, PC, or Crohn's disease. I finally found some relief and felt symptom-free for the subsequent two weeks. However, in December the troubles resurfaced, though to a lesser degree, with occasional loose stools—2-3 times for a few days— and lingering gas. My anxiety about Crohn's returned, and I mistakenly took Algopyrin Complex, which triggered additional stress. **In December, my primary worries included:** - Loose stools resembling Bristol type 5-6, mainly occurring once each morning - Excessive gas often felt trapped in my rectum - My weight stabilized at 62 kg **I underwent various tests:** - Negative results for Giardia and E. coli - Negative FIT tests - Negative MRI (everything appeared normal) - Negative MRE (all normal) - Calprotectin level measured at 18.7 - I was found to have low levels of B9 and Vitamin D, with B12 at 320 and LDL at 5.9 **Moving into January:** - I only had one bowel movement each morning, sometimes loose, but mostly firm in the past three weeks (Bristol 4), compared to my usual Bristol 2. - After meals, I often felt gas building in my rectum, sometimes getting stuck before eventually releasing. This gas, thankfully, rarely had an odor. - Mornings have been troublesome, as I needed to pass gas 2-4 times, and in bed at night, I felt bloated with gas movements. **What I have observed:** - No signs of blood in my stools - No pain - No nocturnal symptoms affecting my sleep - No extraintestinal symptoms - My weight has stabilized without additional loss after recovering some weight Overall, I feel fine, yet the worry about my condition persists in my mind. Previously, I would have bowel movements twice weekly, with little to no gas. It baffles me that I often wake up feeling this uncomfortable. My primary concern is whether I should be worried about Crohn's disease (which occupies my thoughts constantly) or if my symptoms might stem solely from anxiety. Currently, I'm taking the following medications and supplements: - Itopride (doctor suggested it for motility issues) - L-Glutamine - Curcumin - A B-complex supplement - Ashwagandha - I briefly tried rifaximin for three days, but it did not yield significant changes. - I had also experimented with antacids previously, though they proved ineffective. Thank you for your assistance in advance!
