# What can happen when worn cartilage isn't treated *When cartilage soreness continues — cartilage repair Gilbert* > Cartilage repair Gilbert advice on watching soreness, staying active, and knowing when waiting no longer makes sense. ## What helps while you watch it? Write down your walking distance, what brings on swelling, and whether morning stiffness changes. One bad day doesn't tell you much. Keep moving, but stop before the soreness keeps building. Watching is easier with a few honest notes. ## Does every damaged area keep getting worse? No. Some worn areas stay quiet for years, while others make walking and bending harder. A scan by itself won't show how much the worn area will trouble you. Locking, swelling that returns, lost motion, and shorter walks tell you if the joint is changing. More than cartilage can make a knee sore. The meniscus is the pad separating the knee bones, and a tear there may hurt. Weak muscles won't support the joint as well. A leg that bows inward or outward may put more load on one side. If your usual chores haven't changed, it's reasonable to keep watching. ## What if home care hasn't done enough? A QC Kinetix visit may cover joint preservation, which means trying non-surgical care before an operation. Its regenerative treatment choices may include platelet-rich plasma. For this care, the clinic prepares a small sample of your blood, keeps the platelet-rich part, and places it in the sore joint without surgery during the visit that day. The concentrated form has a higher platelet level than the regular form. You'll meet a medical provider, the clinician doing the exam, who'll explain whether this blood-based care fits. It's offered to ease soreness and make daily movement easier, though it doesn't work alike for everyone. Ask how long care may take and what you'll pay. Bring up any past talk of knee or hip surgery. The clinician may say this care isn't right for you. ## What changes mean you shouldn't keep waiting? Book a visit when the joint keeps doing less, even after you ease the work. New catching, giving way, or swelling that returns also needs an exam. If the joint won't fully bend or straighten, don't put it off. Sudden trouble isn't the usual ache. Get prompt care for a locked joint, quick swelling after an injury, or trouble standing on that leg. A hot, red joint with fever needs urgent help. Waiting only works while the joint stays safe. ## Sources 1. In 51 patients whose Outerbridge grade 3 or 4 chondral lesion (mean size 2.1 cm2) was found incidentally during ACL reconstruction and deliberately left untreated, outcomes at 10 and 15 years were not statistically different from matched ACL-only controls on Lysholm, Tegner or IKDC objective scores. At 10 years the subjective IKDC was modestly lower in the defect group (79.6 versus 83.7 points); by 15 years even that difference had gone.

Twelve years after arthroscopic diagnosis, dGEMRIC and T2 mapping of 21 knees with full-thickness cartilage defects - 10 repaired at baseline with microfracture or ACI, 11 left untreated or simply debrided - showed no overall increase in cartilage degeneration in the injured knees. Radiographic osteoarthritis changes were present in 13 of the 21 knees but did not correlate with measured cartilage quality.

In a 19-year multicentre Norwegian follow-up of 322 patients (328 knees) with an arthroscopically verified focal cartilage lesion, mean age 36.8 at index surgery, those who had not needed arthroplasty or osteotomy reported significantly better pain, Lysholm and KOOS scores at final follow-up than before their index operation. By follow-up 17.7% had undergone later cartilage surgery, and nearly 50% met the study's treatment-failure definition, with BMI of 25 or more among the main risk factors.

Pooling 16 of 30 studies covering 868 patients, non-operative management of osteochondral lesions of the TALUS achieved clinical success in 45% of patients (95% CI 40% to 50%) at a median 37 months, with radiographic progression of ankle osteoarthritis in 9% (95% CI 6% to 14%). Roughly half of these lesions do acceptably without an operation.

In a meta-analysis of 63 studies covering 5,397 knees of 4,751 adults with NO symptoms and no injury, the pooled prevalence of cartilage defects on MRI was 24% (95% CI 15% to 34%), rising from 11% in adults under 40 to 43% in adults aged 40 and over. Meniscal tears were present in 10%, bone marrow lesions in 18% and osteophytes in 25%.
