Cases were stratified by the surgeon's training: 1 group with arthroscopic fellowship training and another with nonarthroscopic or no fellowship training. Primary outcomes were intraoperative ROM change and postoperative ROM retention compared with intraoperative and pre\u2010TKA baseline values. Revision and periprosthetic joint infection rates were also collected.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 94 LOA cases were identified, where 48 (51.1%) were performed by nonarthroscopically trained surgeons. Intraoperative ROM improvements were similar between groups in both knee flexion (35.2\u00b0 arthroscopic vs 31.1\u00b0 nonarthroscopic,\n P<\/jats:italic>\n \u2009=\u2009.130) and extension (2.43\u00b0 vs 3.91\u00b0,\n P<\/jats:italic>\n \u2009=\u2009.079). Compared with the intraoperative ROM, procedures performed by arthroscopically trained surgeons showed significantly better long\u2010term retention of both flexion (loss of 4.85\u00b0 vs 15.98\u00b0,\n P\u2009<\/jats:italic>\n =\u2009.006) and extension (gain of 0.50\u00b0 vs loss of 1.58\u00b0,\n P<\/jats:italic>\n \u2009=\u2009.036) at postoperative follow\u2010up. When compared with preprimary TKA baseline ROM, flexion at follow\u2010up was slightly improved in the arthroscopic group but declined significantly in the nonarthroscopic group (gain of 1.66\u00b0 vs loss of 21.76\u00b0,\n P<\/jats:italic>\n \u2009<\u2009.001). Eight revision TKAs (8.51%) occurred after LOA, 6 of which involved nonarthroscopic surgeons, and 1 periprosthetic joint infection case was reported.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n LOA performed by arthroscopic fellowship\u2010trained surgeons results in significantly better retention of postoperative ROM than nonfellowship\u2010trained surgeons when
