Based on the single-center RCT, a total of 30 patients were initially included in each of the Coblation and MSD groups; by the 4-year postoperative follow-up period, 1 patient was lost to follow-up per group. Baseline characteristics between the Coblation and MSD groups were comparable (mean age: 42.9 vs 43.7 years, percentage of males: 43% vs 50%; injury onset: 8.4 vs 7.4 months; body mass index: 26.6 vs 27.8 kg/m [2]; normalized KOOS: 10.8 vs 10.3 points) [5]. Other baseline clinical characteristics are described in greater detail in the published results of the RCT. [5, 25].
