Fluoroscopy-Guided Suture Anchor Placement Yields Excellent Accuracy for Arthroscopic Acetabular Labral Repair: A Cadaveric Study.

ABSTRACT:

Purpose

To determine the accuracy of fluoroscopy-guided suture anchor placement for arthroscopic acetabular labral repair in cadaveric hip specimens.

Methods

Two sports medicine fellowship-trained surgeons performed arthroscopic hip surgery on 6 cadaveric specimens each. Suture anchors were placed at the 11-, 12-, 1-, 2-, 3-, and 4-o'clock positions of the acetabulum in each specimen using a previously described fluoroscopically guided technique. Gross dissection and thin-cut computed tomography scans were performed to assess for accuracy. The insertion angle between the subchondral bone and the drill bit immediately prior to suture anchor insertion was measured, and fluoroscopic visualization of the subchondral bone at each clock-face position was qualitatively graded as good, fair, or poor by 2 independent reviewers.

Results

Overall, 90.3% of attempts (65 of 72) were entirely intraosseous, 5.5% (4 of 72) perforated the articular cartilage, and 4.2% (3 of 72) perforated the far cortex, rates that are comparable with those in previous cadaveric studies. There was no statistically significant difference in accuracy between the surgeons (P = .42) or between the various clock-face positions (P = .63). Neither the insertion angle (P = .26) nor visualization of the subchondral bone (P = .35) was significantly correlated with accuracy by gross dissection.

Conclusions

In a cadaveric hip arthroscopy model, fluoroscopy-guided suture anchor placement yields excellent accuracy rates, similar to non-image-guided techniques.

Clinical relevance

Intra-articular suture anchor placement and intrapelvic suture anchor placement are known complications of arthroscopic acetabular labral repair. Fluoroscopically guided suture anchor placement can be a useful tool for hip arthroscopy surgeons performing acetabular labral repair and reconstruction, potentially reducing the risk of these complications.

Project description:BackgroundArthroscopic suture repair is the main treatment option for hip labral tears; however, anchor insertion and placement from arthroscopic portals is difficult.PurposeTo quantitatively evaluate the safety of various arthroscopic portals for suture anchor placement during hip labral repair.Study designDescriptive laboratory study.MethodsThe computed tomography scans of 20 patients with normally developed hip joints were used to create 3-dimensional models. The distances from the anchor to the articular cartilage (DAC) and from the acetabular insertion point to the cortical bone (DCB) were measured in the anterolateral portal (AL), posterolateral portal (PL), midanterior portal (MAP), medial MAP, and 3 distal anterolateral accessory portals (DALAs): DALA-proximal, DALA-middle, and DALA-distal. Labral tears were divided into anterior (4, 3, and 2 o'clock), lateral (1, 12, and 11 o'clock), and posterior (10, 9, and 8 o'clock) acetabular zones, and the Kruskal-Wallis and Mann-Whitney U test were used to compare DAC and DCB in the zones. The success rate was defined as anchors placed with DAC ≥1 mm and DCB ≥15 mm.ResultsThe DAC was significantly smaller in the AL at 1 o'clock (0.68 ± 0.32 mm; P < .001) and 12 o'clock (0.37 ± 0.30 mm; P < .001), and in the PL at 12 o'clock (-0.35 ± 0.38 mm; P < .001) and 11 o'clock (0.60 ± 0.24 mm; P < .001). The DCB was significantly smaller in the DALA-P at 3 o'clock (8.93 ± 2.12 mm; P < .001) and 11 o'clock (9.59 ± 2.84 mm; P < .001), the MAP at 12 o'clock (13.76 ± 3.89 mm; P < .001) and 11 o'clock (0.27 ± 0.27 mm; P < .001), and the MMA at 12 o'clock (5.96 ± 2.31 mm; P < .001) and 11 o'clock (0 mm; P < .001). Success rates were high for MAP and MMA between 4 o'clock and 1 o'clock, for DALA-proximal at 12 o'clock, for AL at 11 o'clock, and for PL between 10 o'clock and 8-o'clock.ConclusionThere were significant differences in the success rate of anchor placement using different portals during hip arthroscopic labral repair.Clinical relevanceMAP is recommended for labral repair between 4 o'clock and 1 o'clock, DALA-P is recommended between 2 o'clock and 12 o'clock, AL is suitable at 11 o'clock, and PL is suitable between 10 o'clock and 8 o'clock.
