Arthroscopic Acetabular Labral Reconstruction with Fascia Lata Allograft: Clinical Outcomes at Minimum One-Year Follow-Up.

ABSTRACT: The integrity of the acetabular labrum is crucial to normal biomechanics of the hip joint. Disruption of the labral seal could be detrimental to the overall nutrition of the cartilage, leading to its premature degeneration.The aim of this study is to determine the clinical effectiveness of arthroscopic hip labral reconstruction using fascia lata allograft. The hypothesis is that labral reconstruction would provide good clinical outcomes.We retrospectively reviewed all 10 patients who underwent labral reconstruction with fascia lata allograft from January 2013 to October 2015. We assessed improvement in pain and function, complications, and subsequent surgery. The minimum follow-up was 12 months (average, 22.9 months; range, 16-36 months).All patients reported subjective improvement in preoperative pain and function. The mean modified Harris hip score improved significantly from 58 (55-60) to 95 (91-98). The mean change of modified Harris hip score was 36 (31-41) and mean post-operative patient satisfaction score was 9.5(8-10). We observed no radiological progression of arthritis as well as no patient had revision procedure including total hip replacement.Arthroscopic labral reconstruction using a fascia lata tendon allograft is an effective and safe procedure that not only provides excellent clinical outcomes in short term but also potentially prevent continued cartilage degeneration by restoring acetabular labral seal in patients with deficient or resected labrums.

Project description:PurposeTo investigate the preliminary functional and radiographic outcomes after arthroscopic superior capsule reconstruction (SCR) with long head of biceps tendon (LHBT) augmentation for irreparable rotator cuff tears (RCTs).MethodsRetrospective review of medical records was conducted in patients receiving unilateral SCR with fascia lata autograft and LHBT augmentation for irreparable RCTs between January 2016 and March 2019. LHBT was adopted when the integrity was intact or partial tear was less than 50% in width. We used all-suture anchors for folded graft patch fixation with 2 in supraglenoid fossa and another 2 plus two knotless anchors via compression suture-bridging technique in greater tuberosity. Reinforced fixation with side-to-side suture was added between infraspinatus tendon and graft patch, and between proximal LHBT and graft to improve force coupling. Clinical and radiographic outcomes including magnetic resonance imaging analysis at 2-year follow-up were investigated and compared with preoperative status.ResultsConsecutive 18 patients (mean age, 66.1 years) were included. Mean active forward elevation significantly improved from 75.6⁰ to 157.2⁰ (P < .0001), and external rotation from 33.3⁰ to 53.3⁰ (P < .01). Mean acromiohumeral distance increased from 6.1 ± 2.5 mm to 8.5 ± 2.1 mm (P < .001). The American Shoulder and Elbow Surgeons score improved from 33.8 ± 5.6 to 93.4 ± 5.92 points (P < .00001). Comparable outcomes were found in patients with intact LHBT and those with partial tear. Nine patients had partial tear of graft patch (5, tuberosity side; 4 posterior glenoid); 2 patients had complete tear (tuberosity side) showing inferior outcomes.ConclusionsThe index surgery restored superior glenohumeral stability and function of the shoulder with irreparable RCTs. Despite high incidence of partial graft tear, favorable outcomes suggest SCR with biceps tendon augmentation is a feasible treatment for irreparable RCTs.Level of evidenceLevel IV, therapeutic case series.

Project description:BACKGROUND: The risk of radiographic knee degeneration after partial or total meniscectomy is well documented, but no prior study has employed cartilage-sensitive MRI technology to assess degenerative changes after meniscectomy. HYPOTHESIS: Arthroscopic partial meniscectomy results in early articular cartilage wear and subchondral bony degeneration, even in the absence of clinical symptoms, and these findings can be evaluated with cartilage-sensitive MRI. STUDY DESIGN: Retrospective cohort. METHODS: Twenty-nine patients (ages: 15-40) who had undergone isolated arthroscopic partial medial or lateral meniscectomy with at least 5-year follow-up were evaluated. All patients had arthroscopically normal articular cartilage at the time of initial meniscectomy. Seventeen patients (18 knees) underwent partial medial meniscectomy (MM) and 12 patients underwent partial lateral meniscectomy (LM) with mean follow-up of 8.4 and 7.1 years, respectively. Follow-up evaluation included physical examination, outcome questionnaires, and cartilage-sensitive MRI examination with modified Outerbridge grading of articular surfaces. RESULTS: Outerbridge grades II-IV were noted in 64% of medial compartment joint surfaces in group MM knees versus 33% of lateral compartment joint surfaces in group LM knees. Abnormal cartilage surfaces (grades II-IV), subchondral sclerosis, and condylar squaring were all significantly more frequent after medial meniscectomy (p < 0.05). Groups MM and LM had no significant differences among outcome scores, which remained excellent in both groups. A significant negative correlation was found between the severity of cartilage wear and functional scoring in the MM group, suggesting that functional disability lags behind early MRI evidence of degeneration. CONCLUSIONS: Despite optimal preoperative prognostic factors and excellent functional outcomes, MRI evidence of early articular cartilage degeneration was present in both partial medial and lateral meniscectomy patients at a minimum 5-year follow-up. Results support the use of cartilage-sensitive MRI as a noninvasive screening technique to evaluate cartilage changes after arthroscopic partial meniscectomy and may help to counsel the high-risk patient in regard to postoperative activity.
