Grade 0
No radiographic signs of osteoarthritis: no subchondral sclerosis, normal joint space, no subchondral cysts, and a normally spherical femoral head.
CondutaFavorable for joint-preserving surgery: the literature supports hip preservation (arthroscopy/FAI correction, osteotomy) for Tonnis 0-1 hips, with the most predictable outcomes.
RiscoBest prognosis for hip preservation; lowest reported conversion to total hip arthroplasty after arthroscopy.
verificadoNormal values of the hip joint for the evaluation of X-rays (Tönnis)Tonnis grade definitions from open-access PMC7391593 (binary Tonnis modification), Table 1 (grade 0 = no OA); preservation-for-0/1 principle from the same article ('hip preservation for hips graded Tonnis 0 and 1, replacement for 2 and 3').

Grade 1
Mild osteoarthritis: increased subchondral sclerosis with minimal joint-space narrowing and early osteophyte formation; the femoral head contour remains essentially normal.
CondutaStill suitable for joint-preserving surgery: arthroscopy/FAI surgery in selected patients shows durable improvement, though slightly less reliable than grade 0.
RiscoGood prognosis: outcomes after hip preservation are generally predictable in Tonnis 0-1.
Moderate osteoarthritis: small subchondral cyst formation with moderate joint-space narrowing and moderate loss of femoral-head sphericity.
CondutaGray zone: joint preservation/arthroscopy has only a limited, selective role with clinical equipoise; many favor caution because conversion to arthroplasty is markedly more likely.
RiscoWorse prognosis than grade 1: Tonnis 2 at baseline carries a significantly higher risk of conversion to total hip arthroplasty (about 3.4-fold relative to Tonnis 1), with 10-year arthroscopy survivorship ~38% vs ~81% for grade 1.
verificadoNormal values of the hip joint for the evaluation of X-rays (Tönnis)Grade-2 definition from open-access PMC7391593, Table 1 (small cysts, moderate JSN); THA conversion RR 3.44 (95% CI 1.81-6.55) and 10-yr survivorship 38% vs 81% from open-access PMC12205409 (Nikou et al., 10-year hip-arthroscopy outcomes).

Grade 3
Severe (advanced) osteoarthritis: large subchondral cysts, severe joint-space narrowing or obliteration, and severe deformation of the femoral head.
CondutaTotal hip arthroplasty is the realistic treatment: hip-preservation/arthroscopy is generally not recommended at this stage of advanced degeneration.
RiscoPoorest prognosis for preservation: hip-preserving procedures are rarely durable, and arthroplasty is the reliable option.
verificadoNormal values of the hip joint for the evaluation of X-rays (Tönnis)Grade-3 definition from open-access PMC7391593, Table 1 (large cysts, joint-space obliteration, severe head deformation); replacement-rather-than-preservation for Tonnis 2-3 stated in the same article.
