PurposeThe purpose of this study was to determine the anterior cruciate ligament reconstruction (ACLR) failure rate in young patients utilizing the New Zealand (NZ) anterior cruciate ligament (ACL) Registry. The hypothesis was that the ACLR rupture rate would be lower for thicker hamstring graft and bone patellar tendon bone (BPB) grafts in comparison to the classic hamstring technique. The ACLR failure rate was assessed according to graft type and patients’ sex. MethodsThe NZ ACL registry was utilized to identify all patients aged 20 years or younger at the time of surgery who were skeletally mature and had a minimum 2‐year follow‐up. Graft ruptures, defined as an ACL revision, were identified according to graft type (traditional 4 strands hamstring semitendinosus and gracilis, 4 strands semitendinosus, 5–6 strands semitendinosus and gracilis, 7–8 strands semitendinosus and gracilis, bone‐patella‐bone graft). ResultsNine‐hundred and ninety‐two patients were included. At a mean follow‐up of 38 months, 52 cases of graft rupture were recorded, (overall failure rate: 5.2%). The failure rate was not statistically influenced by the graft diameter. Patients with a thinner graft (< 8 mm—196 patients) had a similar failure rate (6%) to patients with a thicker graft (8 mm or more—485 patients) (6.2%). There was a lower failure rate in the BPB group (3.1%) versus all hamstrings group (6%) (ns). Finally, BPB in females had a lower failure rate than all hamstring constructs together (0% versus 5.1%; p = 0.023) ConclusionIn a young population traditional four‐strand hamstring grafts, multiple strand configurations or BPB ACLR, whatever their size (> or < 8 mm), showed no significant difference in the failure rate in the NZ ACL registry. Female patients who had an ACL reconstruction with BPB graft had a significant lower failure rate than patients who had a hamstring graft. Level of evidenceIII.

Ankle fractures represent the third most common fragility fracture seen in elderly patients following hip and distal radius fractures. Non-operative management of these see complication rates as high as 70%. Open reduction and internal fixation (ORIF) has complication rates of up to 40%. With either option, patients tend to be managed with a non-weight bearing period of six weeks or longer. An alternative is the use of a tibiotalocalcaneal (TTC) nail. This provides a percutaneous treatment that enables the patient to mobilise immediately. This case-series explores the efficacy of this device in a broad population, including the highly comorbid and cognitively impaired.We reviewed patients treated with TTC nail for acute ankle fractures between 2019 and 2022. Baseline and surgical data were collected. Clinical records were reviewed to record any post-operative complication, and post-operative mobility status and domicile. 24 patients had their ankle fracture managed with TTC nailing. No intra-operative complications were noted. There were six (27%) post-operative complications; four patients had loosening of a distal locking screw, one significant wound infection necessitating exchange of nail, and one pressure area from an underlying displaced fracture fragment. All except three patients returned to their previous domicile. Just over two thirds of patients returned to their baseline level of mobility.This case-series is one of the largest and is also one of the first to include cognitively impaired patients. Our results are consistent with other case-series with a favourable complication rate when compared with ORIF in similar patient groups. The use of a TTC nail in the context of acute, geriatric ankle trauma is a simple and effective treatment modality. This series shows acceptable complication rates and the majority of patients are able to return to their baseline level of mobility and domicile.

PFFs are an increasing burden presenting to the acute trauma services. The purpose of this study is to show that cemented revision for Vancouver B2/B3 PFFs is a safe option in the geriatric population, allows early pain-free weight bearing and comparable to a control-group of uncemented stems with regard to return to theatre and revision surgery.A retrospective review was conducted of all PFFs treated in a Level 1 trauma centre from 2015-2020. Follow up x-rays and clinical course through electronic chart was reviewed for 78 cemented revisions and 49 uncemented revisions for PFF. Primary endpoints were all cause revision and return to theatre for any reason. Secondary endpoints recorded mobility status and all-cause mortality.In the cemented group there were 73 Vancouver B2, 5 Vancouver B3 PFF; the mean age was 79.7 years and mean radiological follow-up of 11.9 months. In the cementless group there were 32 Vancouver B2 and 17 Vancouver B3 PFFs; with all 49 patients undergoing distally bearing uncemented revision, the mean age was 72.7 years and mean radiological follow-up of 21.3 months.Patients treated with a cemented prosthesis had significantly higher ASA score (2.94 -v- 2.43, p<0.001). The primary endpoints showed that there was no significant difference in all cause revision 3/78 and 5/49 p=0.077, or return to theatre 13/78 -v- 12/49 p=0.142.Secondary endpoints revealed no significant difference in in-hospital mortality. The cementless group were more likely to be mobilising without any aid at latest follow-up 35/49 -v- 24/78 p<0.001.The use of cemented revision femoral component in the setting of PFFs is one option in the algorithm for management of unstable PFFs according to the Vancouver classification. Evidence from this case-control study, shows that the all-cause revision and return to theatre for any cause was comparable in both groups.
