- Mosaicplasty can offer a good outcome at long-term for small lesions.
- Low number of plugs used is related to better outcome.
- Joint degeneration progression is present at the treated compartment.
BackgroundThis study aims to document the long-term results in a group of patients treated with arthroscopic mosaicplasty for knee cartilage lesions, both in terms of clinical outcome and joint degeneration progression, evaluated by radiographs.Methods26 patients (19 men and 7 women, mean age 29Â years, mean BMI 23) treated arthroscopically with mosaicplasty for cartilage defects of the femoral condyles (mean/median/mode size 1.9 standard deviation, SD 0.6Â cm2) were prospectively evaluated at 12Â years follow-up. The clinical outcome was analyzed with IKDC and Tegner scores. Range of motion, transpatellar and suprapatellar circumferences were also measured. Radiographs with weight-bearing antero-posterior and Rosenberg projections were used for radiological evaluation in 18 patients, applying both Kellgren-Lawrence score and a direct joint line measurement to assess osteoarthritis.ResultsA significant improvement in all clinical scores was obtained from the basal evaluation to the 12-year follow-up (IKDC subjective score from 36.8 standard deviation, SD 13.0 to 77.3 standard deviation, SD 20.6, PÂ <Â 0.0005; Tegner score from 2.9 standard deviation, SD 1.3 to 5.2 standard deviation, SD 2.5, PÂ <Â 0.0005), and better results in patients with a higher pre-injury activity level and those requiring fewer plugs. The radiographic evaluation showed significantly poorer Kellgren-Lawrence scores and a reduction of the joint line in the treated compartments. Knees with 3-4 plugs presented a significantly higher joint degeneration level with respect to those implanted with 1-2 plugs.ConclusionsMosaicplasty is an effective surgical option for small lesions of the femoral condyles. Although joint degeneration progression was present at 12Â years, this did not affect significantly the clinical outcome which was satisfactory at long-term follow-up.Level of evidenceIV, case series.
