Introduction. In order to prepare hamstring autograft, suture fixation to the tendon is required to secure and handle the tendon during harvest and preparation. We use a simple, grasping suture which doesn't require suture of the tendon, thus saving time and avoiding violation of the graft itself. We present this technique, with results of mechanical testing compared to a standard whip suture, traditionally used to handle hamstring autograft. Methods and materials. Twelve uniform ovine flexor tendons were prepared. A number two braided polyester suture was used in all cases. Six tendons were prepared with a standard, non-locking whip-suture, maintaining uniformity of suture bite and working length between samples. Six tendons were prepared with the utility suture, also taking care to maintain uniformity. The suture was applied by tying the thread around the tendon with a single-throw granny knot then symmetrically wrapping the suture ends from proximal to distal and securing with another single throw, allowing compression of the tendon with longitudinal tension on the suture. All the samples were tested to failure in uniaxial tension in a materials testing machine. Peak load values and load/displacement curves were acquired and results analysed with a two-sample T-test assuming significance at P<0.05. Results. Modes of failure between the groups, as characterised by the load/displacement curves were quite distinct. Peak load to failure was lower in the utility suture group but all failures occurred when the suture snapped. Thus the peak load to failure of the suture/tendon construct exceeded the breaking strain of the suture material. Conclusion. The grasping utility suture described here is sufficiently strong to harvest and handle hamstring autograft without passing a needle through the graft, saving time and avoiding violation of the graft itself. The lower loads at failure, despite failure occurring due to suture snapping, may reflect differing knot orientation between groups

Background

Injury to the ACL is a significant problem and can cause further damage to the internal structures of the knee. ACL injury is associated with injuries to other structures in the knee such as the meniscus and chondral cartilage. Such intra articular injuries pre-dispose the knee to develop arthritis. This injury is usually seen in young and active people usually related to sporting injuries. There is a paucity of literature on the influence of anthropometric features on the hamstring graft obtained in ACL reconstruction, although there are studies on the sex based differences affecting the hamstring graft. This study was undertaken to assess the influence of anthropometric measurements on the graft thickness obtained at ACL reconstruction surgery within the UK population.

Introduction. Over the past 30 years multiple wars and embargos have reduced healthcare resources, infrastructure, and staff in Iraq. Subsequently, there are a lack of physiotherapists to provide rehabilitation after an anterior cruciate ligament reconstruction (ACLR). The implementation of home-based rehabilitation programmes may provide a potential solution to this problem. This study, set in in the Kurdistan region of Iraq, describes the epidemiology and outcomes of anterior cruciate ligament reconstruction (ACLR) followed by home-based rehabilitation alone. Methods. A cohort observational study of patients aged ≥ 16 years with an ACL rupture who underwent an ACLR under a single surgeon. This was performed arthroscopically using a hamstring autograft (2 portal technique). Patients completed a home-based rehabilitation programme of appropriate simplicity for the home setting. The programme consisted of stretching, range of motion and strengthening exercises based on criterion rehabilitation progressions. A full description of the programme is provided at: . https://ngmvcharity.co.uk/. . Demographics, mechanisms of injury, operative findings, and outcome data (Lysholm, Tegner Activity Scale (TAS), and revision rates) were collected from 2016 to 2021. Data were analysed using descriptive statistics. Results. The cohort consisted of 545 patients (547 knees), 99.6% were male with a mean age of 27.8 years (SD 6.18 years). The mean time from diagnosis to surgery was 40.6 months (SD 40.3). Despite data attrition Lysholm scores improved over the 15-month follow-up period, matched data showed the most improvement occurred within the first 2 months post-operatively. A peak score of 90 was observed at nine months. Post-operative TAS results showed an improvement in level of function but did not reach pre-injury levels by the final follow-up. At final follow-up, six (1.1%) patients required an ACLR revision. Conclusion. Patients who completed a home-based rehabilitation programme in Kurdistan had low revision rates and improved Lysholm scores 15 months post-operatively. To optimise resources, further research should investigate the efficacy of home-based rehabilitation for trauma and elective surgery in low- to middle-income countries and the developed world
