Dr. Aaron Krych discuss Arthroscopic labral repair versus selective labral debridement in female patients with femoroacetabular impingement.
36 patients (all female) were randomized to determine which treatment, labral repair or labral debridement, was more effective for femoroacetabular impingement. Patients received either labral repair or labral debridement, and were followed-up at a minimum of one year postoperatively. Results suggest that labral repair displayed superiority in improving clinical outcome and propioception of hip function compared to the debridement procedure. Patient subjective outcome was also superior in the labral repair group.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?

Fragility Indexは、重要な所見の解釈を助けるツールで、結果の強さの尺度を提供します。Fragility Indexは、その所見が有意でなくなるために、二項対立の結果に追加する必要がある連続した事象の数を表します。数値が小さいほど弱い所見を表し、数値が大きいほど強い所見を表します。
なぜ今この研究が必要なのですか？
Femoroacetabular impingement arises through either a cam impingement or pincer impingement, which are characterized by an irregularly shaped femoral head/neck or positional problems of the acetabulum, respectively. A number of studies have reported outcomes associated with either labral debridement or labral repair, but there has yet to be a prospective randomized study to compare the two procedures.
主な研究課題は何ですか？
Which treatment of femoroacetabular impingement - labral debridement or repair - provided superior results in functional and/or subjective outcome when measured at least 1 year after surgery in female patients?
重要な知見は？
- HOS for activities of daily living were improved from 68.2 to 91.2 in the repair group and from 60.2 to 80.9 in the debridement group. Both these improvements were significant within-group differences, and the postoperative score was significantly greater for the repair group (p<0.05).
- Improvement in HOS-sports was from 47.5 preoperatively to 88.7 postoperatively in the repair group, and 40.6 to 76.3 in the debridement group. Improvement was significantly greater in the repair group (p<0.05).
- 76% of patients in both groups rated their hip function as "severely abnormal" preoperatively. Postoperatively, 72% (n=13) of repair patients reported "normal" function, 22% (4) "near normal", 6% (1) "abnormal" and none reported "severely abnormal" function. In contrast, 28% (5) of debridement patients experienced "normal" function, 50% (9) "nearly normal", 17% (3) "abnormal" and 6% (1) "severely abnormal". The postoperative ratings were significantly better in the repair group (p=0.046).
最も覚えておくべきことは？
Patients who were treated with labral repair experienced significantly greater improvements in clinical outcome, and a larger percentage of patients had felt that their hip function had been returned to "normal" or "near normal" when compared to patients who received labral debridement.
それが私の患者ケアにどのように影響するか？
These findings favour the use of labral repair over debridement in the treatment of patients with femoroacetabular impingement. However further, larger-scale RCTs should be conducted before the evidence can be considered conclusive.
