'German gel' is ChondroFiller®, a CE-marked collagen scaffold that recruits the patient's own repair cells to initiate cartilage repair.

Hormonal contraception roughly doubles the risk of hip labral tear in women, yet labral tears are routinely misdiagnosed as muscle strain, delaying treatment when early diagnosis is crucial for preserving hip function.

Three repair pathways address focal knee cartilage defects—ChondroFiller injection (outpatient ultrasound-guided, £3,000), OATS (single-stage arthroscopic surgery, ~£14,000), and MACI (two-stage surgery with laboratory cell culture, £25,000–£35,000)—but choice hinges on surgical candidacy and rehabilitation capacity, not defect size alone.

ChondroFiller injections cost £3,000 to £8,000 at London Cartilage Clinic depending on defect size, with all fees including consultation, imaging, product, antibiotic cover, and follow-up; the treatment is entirely self-pay.

Patellofemoral pain syndrome—a kneecap that doesn't track smoothly—is more common in women because of pelvic anatomy. Three menstrual-cycle shifts amplify this structural problem: oestrogen increases connective-tissue laxity, prostaglandins sensitise joint structures, and falling hormones impair neuromuscular control.
