Practical reading from Professor Paul Lee and the Lincolnshire Hip Clinic team — across hip replacement, Arthrosamid, ChondroFiller, PRP and the wider world of hip and groin pain.
ChondroFiller is a collagen scaffold that gels within the hip and prompts the body's own cells to rebuild cartilage, with 81% of candidates with focal defects achieving good or excellent repair at five years.
For focal hip cartilage defects, microfracture produces scar-like repair tissue that breaks down within two to three years and damages the underlying bone; ChondroFiller injection—a collagen scaffold—preserves bone and maintains good outcomes in 81% of patients at five years.
The collagen scaffold recruits the patient's own cells to form cartilage; outcome scores improve by approximately 30 points over twelve months, meaningfully reducing hip pain and improving mobility.
Hip resurfacing reduces dislocation risk by a factor of 13.45 compared with total hip replacement, according to a 2025 network meta-analysis of nearly 794,000 patients.
ChondroFiller is a collagen scaffold for focal hip cartilage defects; Arthrosamid is a hydrogel for diffuse osteoarthritis. The two injectables are not interchangeable — candidacy hinges on damage type, not pain severity.
Hip cartilage cannot heal itself; defect size and osteoarthritis grade determine whether surgical repair remains viable—autograft transfer for lesions under 2 cm², matrix-based reconstruction for larger defects—with surgical options becoming ineffective once osteoarthritis reaches Tönnis grade 2 or above, at which point injection-based symptom management takes over.
Liquid Cartilage™ is an outpatient ultrasound-guided injection that harnesses the patient's own cells to repair cartilage defects, but only in focal lesions surrounded by intact tissue. Bone-on-bone wear or widespread cartilage loss eliminates the margins this treatment needs.
ChondroFiller hip injections start at around £3,000 for focal cartilage defects, with pricing scaled by lesion size and all-inclusive tariffs covering consultation, ultrasound guidance, the collagen scaffold device, antibiotics, and follow-up.
ChondroFiller, a collagen scaffold injected ultrasound-guided into the hip, works by establishing a biological environment for the body's own cells to regenerate cartilage over 12–24 months. Available at £2,995 per injection at Lincolnshire Hip clinics in Sleaford and Grantham, the treatment targets early-to-moderate focal cartilage defects.
