The question of whether to reconstruct an ACL-deficient knee as early as possible following injury or to delay surgery remains unanswered. Early reconstruction potentially reduces the risk of secondary damage. However, there is also concern regarding the risk of arthrofibrosis if surgery is undertaken too soon. The aim of this study was to investigate whether injury-to-surgery delay determines ACL-reconstruction outcomes at up to 2years post-operatively.

A retrospective analysis of prospectively collected data from 211 knees with isolated primary ACL ruptures was performed. Patients were examined preoperatively, at 6months, 1 year, and 2 years post-operatively using International Knee Documentation Committee (IKDC) and Lysholm scores. Side to side differences in knee laxity were also measured with a KT1000 arthrometer. Spearman's rho correlations were used to associate injury-to-surgery delay with outcome scores.

Outcomes scores significantly increased for both IKDC (p<0.05) and Lysholm (p<0.05) questionnaires. Significant positive correlations (p<0.05) were also found between injury-to-surgery delay and IKDC and Lysholm subjective scores. Strongest correlation coefficients were noted at the 2yr follow-up for both IKDC and Lysholm scores (r = 0.79 and 0.8 respectively). Side-to-side laxity measures also showed significant positive correlations with injury-to-surgery delay at 1 year (r = 0.17) and 2 year (r = 0.41) follow ups. The positive correlation suggests that delayed surgery is positively related to subjective outcomes, as well as objective measures of knee laxity.

However, this relationship also suggests that other factors such as the patient's functional status at time of surgery may play a role in their post-operative function. For example, those who can compensate for the ruptured ligament may function well following delayed surgery. These findings highlight the need for more detailed investigation of the interaction between functional status, injury-to-surgery delay and post-operative recovery.

Aim. Pelvic osteomyelitis following pressure ulceration results in substantial patient morbidity. Previous studies have reported a heterogenous approach to diagnosis and medical management by physicians, suggesting equipoise on key clinical questions. This study hypothesised that the same equipoise exists amongst Orthopaedic surgeons. Method. An 18-question multiple-choice questionnaire was designed through an iterative feedback process until the final version was agreed by all authors. Likert-type scale responses were used with graded responses (e.g., never/fewer than half of patients/around half of patients/more than half of patients/every patient). The online survey was sent to members of the Musculoskeletal Infection Society (MSIS), the European Bone and Joint Infection Society (EBJIS), and the ESCMID Study Group for Implant-Associated Infections (ESGIAI). No incentive for participation was provided. Results. Amongst respondents, 22/41 were based in Europe and 10/41 from the USA. The majority (29/41) had been in clinical practice between 5—24 years. There was a high priority placed on bone biopsy histology, culture-positive bone sampling, and palpable bone without periosteal covering for diagnosis. Multidisciplinary team approach with plastic surgery involvement at the index procedure was advocated. The strongest indications for surgical intervention were source control for sepsis, presence of an abscess/collection, and prevention of local osteomyelitis progression. Physiological/psychological optimisation and control of acute infection were the primary determinants of surgical timing. There was low utilisation of adjunctive surgical therapies. Local/regional primary tissue transfer or secondary healing with/without VAC were the preferred techniques for wound closure. Recurrent osteomyelitis was the most common reason for prolonged antimicrobial therapy. The majority received bedside advice from an infectious disease-specialist but a quarter of respondents preferred telephone advice. Conclusions. Amongst an international cohort of Orthopaedic Surgeons there was a heterogenous diagnostic and therapeutic approach to pressure-related pelvic osteomyelitis

Aim. In the context of total knee arthroplasty (TKA), trauma with perigenicular fracture fixation or oncological surgical treatment, soft tissue defects can expose critical structures such as the extensor apparatus, the knee joint, bone or implants. This work compares soft tissue reconstruction (STR) between a classical pedicled gastrocnemius (GC) muscle flap and a pedicled chimeric sural artery perforator (SAP) musculocutaneous GC flap in complex orthoplastic scenarios. Method. A retrospective study was conducted on prospectively maintained databases in three University Hospitals from January 2016 to February 2021 after orthopaedic, traumatological or oncological treatment. All patients with a perigenicular soft tissue defect and implant-associated infection were included undergoing STR either with a pedicled GC flap or with a pedicled chimeric SAP-GC flap. The outcome analysis included successful STR and flap related complications. The surgical timing, preoperative planning and surgical technique are discussed together with the postoperative rehabilitation protocol. Results. 43 patients were included (22 GC muscle flaps, 21 SAP-GC musculocutaneous flaps). The GC and SAP-GC patient group were comparable in terms of age, comorbidities, defect size and follow-up. The incidence of flap related complications was comparable among the two groups. Specifically, in the SAP-GC group 1 wound dehiscence at the recipient site occurred as well as 1 distal muscle flap necrosis, 1 distal skin flap necrosis, 1 donor site infection and 1 donor site wound dehiscence. Furthermore, the donor site was closed in 9 patients while a skin graft was used in 12 patients. A significant difference was recorded with regard to re-raising the flap for further orthopaedic treatment: In the SAP-CG group (re-raise in 11 patients) no problems occurred while in the GC group (re-raise in 14 patients) in 6 patients the soft tissue did not heal completely. Conclusions. According to our clinical experience, the pedicled chimeric SAP-CG musculocutaneous flap is a relevant further development of the classical GC workhorse flap for perigenicular STR, in multiple staged procedures

Evaluate the complications and outcomes of off-hours spinal metastasis surgery. Retrospective analysis of a prospective collected data. Preoperative, operative and post-operative data were collected as well as the complications and Frankel score at all time checkpoints. Off-hours surgery was defined as surgery starting between 17:00 and 8:00 the following day or surgery during the weekend. p < 0 .05 was defined as statistical significance threshold. 376 patients were included with an incidence of off-hours surgery of 32%. There was an increase of neurologic complication in the off hours group. This was associated with a higher ASA score and older population group. Oddly, there was decreased operative time with off-hours surgery with no difference in bleeding and number of fusion levels. Nonetheless, there was a higher percentage of neurologic improvement with off hours surgery compared to in-hours surgery. Finally, there were no effect on patients' survival in this patient population. To our knowledge, this is the first report of the effect of off-hours surgery on complications and outcomes of spinal metastasis. Greater neurological compromise and higher age and ASA scores were associated with higher incidence of off-hours surgery. It is associated with decreased surgical time with higher percentage of neurological improvement. Finally, there is no effect of surgical timing on survival rates

Supracondylar fractures of the humerus have historically been treated as an emergency case and operated on at the earliest opportunity. We undertook a study to examine whether surgical timing affects the need for open reduction or peri-operative complications in the type III injuries. Between August 1995 and August 2004, 534 patients presented and were referred to our unit with these fractures. Those with closed, type III injuries without vascular compromise were selected (171 patients). These were divided into 2 groups: those undergoing surgery less than 8 hours from presentation (126 patients) and those undergoing surgery more than 8 hours from presentation (45 patients). The two major differences between the two groups were: the delayed group were more likely to undergo open reduction (33.3% v 11.2%, p<0.05) and the mean length of the surgical procedure was increased (105.1 minutes v 69.2 minutes, p<0.05). Delay in treatment of the type III supracondylar fractures is associated with an increased need for open reduction and a longer procedure. We would recommend treating these injuries at the earliest opportunity

Late presentation and rapid progression of Dupuytren's contracture significantly increases operating time, complications and likelihood of incomplete correction; however, surgical timing is usually more a function of waiting list length than of clinical criteria. We sought to measure the rate of progress of Dupuytren's contracture. All patients with Dupuytren's contracture referred to the sole Consultant Hand Surgeon for Highland Region between June 1997 and February 2003 were prospectively included. Fixed flexion deformities at each finger joint and thumb-index angle to the point of firm resistance to extension were recorded by a single observer (QGNC) at presentation and immediately pre-operatively. Of 151 participants 37% had a family history. There was a male predominance of 5:1, with bilaterality in 77% at presentation. Five percent had diabetes, 3% had epilepsy, 52% acknowledged tobacco habits and 24% regular alcohol in excess of recommended limits. Angular deterioration was observed in 52% of digits, over one quarter of this occurred at the small finger joints, where 58% of PIPJs progressed. Mean delay from presentation to surgery was 11 months (2-55.5). Mean age at presentation of 62 (16-86) years did not correlate with angular deformity at presentation or with velocity of deterioration or with manual/non-manual employment. Mean severity of deformity at presentation for manual (34°) was double non-manual workers (17°) although angular deterioration was faster in the non-manual group (3.8 cf 0.7°/month respectively). Similar speeds of deterioration were seen at MCPJ and PIPJ, speed of deterioration was 2.2°/month for each of the three ulnar digits. Speed of deterioration correlated (r=0.7) with severity of deformity at presentation for ring and small fingers. This study offers the first quantification of rate of deterioration in Dupuytren's contracture. This could be used as a waiting list tool to predict the delay before a digit is likely to pose increased surgical risk
