RESUMEN

AIM OF THE STUDY: To describe the surgical findings of the anterolateral complex in patients with the "unhappy triad" lesion of the knee. METHOD: One hundred and twenty-five consecutive patients presenting with acute anterior cruciate ligament (ACL) tears were selected for this study. Only cases, evaluated with a valgus stress test under fluoroscopy, with a medial opening more than 5 mm of the medial collateral ligament (MCL) were included in the study (11 patients). For the included cases, open MCL surgical repair was performed only in cases with a valgus stress test more than 10 mm as revealed by fluoroscopy (3 patients). All included cases (11 patients) underwent ACL reconstruction and exploration of the anterolateral complex that was then assessed, photographed, classified, and eventually repaired. RESULTS: At clinical evaluation under anaesthesia, all patients presented a positive Lachman test and a pivot shift test graded as ++ in four cases and +++ in five cases, not valuable in two cases. At surgical exploration, the anterolateral complex was involved in all cases (11 patients): one case demonstrated a type I injury, eight cases a type II injury, two cases a type III injury, and no patient with a type IV injury (Segond's fracture). All anterolateral complex lesions were repaired by direct suture and re-tensioning. DISCUSSION: On the basis of a recent analysis performed by other authors, we could speculate that injuries of ACL and anterolateral compartment occur in the very early phase of the injury when the knee is forced into internal rotation. The MRI evidence of bone bruising in the lateral compartment in most cases of the present series support the hypothesis of an internal rotation torque. CONCLUSIONS: The unhappy triad of injuries to the knee is actually a tetrad involving not just the ACL, MCL, and medial/lateral meniscus but also involved the anterolateral complex.

RESUMEN

Purpose: To assess the utility, safety, and accuracy of in-office needle arthroscopic (IONA) synovial biopsy as a diagnostic tool during treatment of drug-resistant monoarticular inflammatory arthritis of the knee. Methods: Consecutive patients diagnosed with rheumatoid or psoriatic arthritis with treatment-resistant monoarticular knee involvement who underwent in-office needle arthroscopic synovial biopsy were considered for inclusion. The exclusion criteria were any current malignancies or infection. All patients underwent systematic physical and laboratory examination. IONA was undertaken to inspect the macroscopic appearance of the joint, choose the biopsy site, and classify synovial inflammation. Once collected, synovial tissue specimens were examined histologically using the Krenn scoring system. Results: In total, 12 patients (9 male and 3 female, median age 57 [interquartile range {IQR} 8] years, median disease duration 156 [IQR 201] months) affected by psoriatic arthritis (n = 6) or rheumatoid arthritis (n = 6) were included in this study. Median operating time was 12 (IQR 11) minutes. Three biopsies per patient were collected. The success rate of specimen collection was 97%, the median postoperative 0-10 visual analog scale pain score was 2 (IQR 3), and only one minor complication occurred. Conclusions: Knee IONA with synovial biopsy is an effective and well-tolerated procedure that can help clinicians formulate specific treatment strategies in patients with refractory pain in the setting of rheumatoid and psoriatic arthritis. Level of Evidence: IV, Therapeutic case series.
