“…In cases of pronounced anterolateral rotational instability of the knee joint, a growing number of publications postulate a simultaneous reconstruction of the ALL and the ACL [ 15 , 16 , 22 , 32 , 36 , 38 ]. Various operative techniques have been proposed [ 13 , 15 , 19 , 35 , 43 ]. Knees with persistent internal rotational instability may be more prone to suffer a reruptur secondary to the ACL reconstruction as ongoing pivot-shift phenomenon and rotational laxity has been shown to correlate with inferior clinical outcome [ 3 , 23 ].…”

Purpose The aim of the current study was to objectify the rotational laxity after primary anterior cruciate ligament (ACL) rupture and rerupture after ACL reconstruction by instrumented measurement. It was hypothesized that knees with recurrent instability feature a higher internal rotation laxity as compared to knees with a primary rupture of the native ACL. Study design Cross-sectional study, Level of evidence III. Methods In a clinical cross-sectional study successive patients with primary ACL rupture and rerupture after ACL reconstruction were evaluated clinically and by instrumented measurement of the rotational and antero-posterior laxity with a validated instrument and the KT1000®, respectively. Clinical examination comprised IKDC 2000 forms, Lysholm Score, and Tegner Activity Scale. Power calculation and statistical analysis were performed (p value < 0.05). Results 24 patients with primary ACL rupture and 23 patients with ACL rerupture were included. There was no significant side-to-side difference in anterior translation. A side-to side difference of internal rotational laxity ≥ 10° was found significantly more frequent in reruptures (53.6%) compared to primary ruptures (19.4%; p < 0.001). A highly significant relationship between the extent of the pivot-shift phenomenon and side-to-side difference of internal rotation laxity could be demonstrated (p < 0.001). IKDC 2000 subjective revealed significantly better scores in patients with primary ACL tear compared to patients with ACL rerupture (56.4 ± 7.8 vs. 50.8 ± 6.2; p = 0.01). Patients with primary ACL tears scored significantly better on the Tegner Activity Scale (p = 0.02). No significant differences were seen in the Lysholm Score (p = 0.78). Conclusion Patients with ACL rerupture feature significantly higher internal rotation laxity of the knee compared to primary ACL rupture. The extend of rotational laxity can be quantified by instrumented measurements. This can be valuable data for the indication of an anterolateral ligament reconstruction in ACL revision surgery.

Tenosynovial giant cell tumor (TGCT) is defined by the World Health Organization (WHO) as a family of lesions most often arising from the synovium of joints, bursae and tendon sheaths. It is composed of synovial- like mononuclear cells, admixed with multinucleate giant cells, foam cells, siderophages and inflammatory cells (1). It can have various clinical manifestations, and is therefore subdivided in a diffuse and a localized/ nodular subtype. Furthermore, the lesions can have an intra- or extra-articular location. The purpose of this paper is to present the case of a 41-year-old male suffering from multifocal extra- and intra-articular TGCT of the right knee, with involvement of the pes anserinus bursa and an anterior cruciate ligament (ACL) autograft respectively. The ACL reconstruction was performed 11 years prior to the diagnosis of the TGCT, using tendons harvested from the pes anserinus. Our case illustrates the risk of transferring TGCT from an extra- to intra-articular location during ACL reconstruction, when using tendons of a pes anserinus prone to develop this condition. To our knowledge, no similar case was published in the literature so far.
