Case reports, open techniques, and those associated with osteonecrosis were excluded. Articles were assessed for sample size, location, severity, and size of chondral defects, and the surgical technique. Associated injuries, follow\u2010up duration (months), and functional outcomes were recorded. Study cohorts were defined by a surgical technique (debridement\n                      <jats:italic>v<\/jats:italic>\n                      microfracture\n                      <jats:italic>v<\/jats:italic>\n                      autologous chondrocyte transplantation [ACT]).

After pooling the data, there were 579 (64.7%) debridements, 279 (31.2%) microfracture, and 37 (4.1%) ACT performed. Patients were followed for an average of 27.1\u00a0months (range: 5 to 72\u00a0months). All lesions treated with either a microfracture or ACT were high grade (Outerbridge 3 to 4). However, lesion size was significantly larger in ACT\u2010treated patients compared with those who underwent microfracture (357.3 \u00b1 96.0\u00a0mm\n                      <jats:sup>2<\/jats:sup>\n                      <jats:italic>v<\/jats:italic>\n                      149.5 \u00b1 20.7\u00a0mm\n                      <jats:sup>2<\/jats:sup>\n                      ;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .020).

In addition, although there were no differences in patient characteristics and demographics based on the surgical technique, we confirmed the hypothesis that lesion size varied significantly between arthroscopic techniques, and that the decision to use one technique over another\u00a0may be determined by the size of the defect. Therefore, lesion size is likely to influence the development of hip\u2010 and technique\u2010specific indications, and may also represent a useful metric for success of surgical intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level\u00a0of\u00a0Evidence<\/jats:title>\n                    <jats:p>Level IV,
