Patellar dislocation is a common presentation with a clear management pathway. Sometimes, however, what a patient experiences as the patella dislocating may, in fact, be ACL insufficiency. We reviewed case notes and imaging of 315 consecutive ACL reconstructions, collecting data on the date and mechanism of injury, time to MRI, and reconstruction. We noted cases initially diagnosed as patellar dislocation. 25 of 315 (7.9%) patients were initially diagnosed with a patellar dislocation. Subsequently, however, MRI scans revealed no evidence of patellar dislocation and instead showed ACL rupture with pathognomonic pivot-shift bony oedema. The false patella dislocation group were 32% female and had an average age of 25; the rest of the group average age was 27.1 and there were a lower proportion of females; 21%. The false patella instability patients had a median waiting time of 412 days from injury to operation (range: 70-2445 days), compared to 392 days (range: 9 – 4212 days) for rest of the patients. 5 of the remaining 290 had MRIs showing patella oedema with medial patello-femoral ligament injury in addition to their ACL rupture. From our literature search this is a new finding which shows that ACL rupture can present with symptoms suggestive of patellar dislocation. These findings raise the risk that there are a group of people who have been diagnosed with patellar instability who instead have ACL insufficiency and so are at risk of meniscal and chondral damage. Further research should analyse those diagnosed with patellar instability to quantify missed ACL injuries

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

ACL (anterior cruciate ligament) partial tears include various types of lesions, and an high rate of these lesions evolve into complete tears. Most of the techniques described in literature for the surgical treatment of chronic partial ACL tears, don't spare the intact portion of the ligament. Aim of this study was to perform a prospective analysis of the results obtained by augmentation surgery using gracilis and semitendinosus tendons to treat partial sub-acute lesions of the ACL. This technique requires an “over the top” femoral passage, which enables salvage and strengthening of the intact bundle of ACL. The study included 97 patients treated consecutively at our Institute from 1993 to 2004 with a mean injury-surgery interval of 23 weeks (12–39). Patients were followed up by clinical and instrumental assessment criteria at 3 months, 1 year and 5 years after surgery. Clinical assessment was performed with the IKDC form. Subjective and functional parameters were assessed by the Tegner activity scale. Instrumental evaluation was done using the KT-2000 instrument: the 30 pound passive test and the manual maximum displacement test were performed. We obtained good to excellent results in 95.9% of cases. We didn't observed recurrences in ligamentous laxity. We believe that the described technique has the advantage of being little invasive, compatible with the ACL anatomy, and enables very rapid functional recovery and return to sport

Introduction. Interest in platelet-derived growth factors has been increasing as an adjunct in surgical techniques for tissue repair. Its use in ligament injuries repair has been studied mainly in animals. The authors intend to study growth factors influence in ACL repair using BTB graft. Material. 20 individuals underwent ACL rupture BTB arthroscopic repair, using Double Incision Mini-Invasive Technique. MRI (3-Tesla) images. GPSIII ® System to obtain Platelet-Rich Plasma (PRP) thrombin activated. Methods. Prospective study consisting of 2 groups of 10 patients each. Surgical technique, fixation method and postoperative protocol were the same. In the study group (SG-10 patients) graft was imbued with PRP and the remaing plasma was intra-articularly injected. The MRIs took place 6 weeks and 6 months after the procedure with and without gadolinium-DTPA enhancement. Evaluation was performed blindly by independent radiologists concerning femoral tunnel integration, sinovialization process and nonspecific synovitis. Clinical and functional status evaluation: IKDC. Statistical analysis in SPSS®. Results. Radiological evaluation was similar in both groups. In the Study Group at 6 weeks we verified less joint effusion and synovitis. At 6 months: no diference in integration in femoral tunnel, and in granulation tissue around the femoral tunnel in graft sinovialization. IKDC (mean ± SD) with PRP: pre-operative −45,66 ±6,98, post-operative −94,35 ±3,54 (Age-29 ± 10), without PRP: preoperative −48,02 ±12,68, post-operative −91,7 ±6,99 (Age −31 ±10). There are no statistical differences between the groups with and without PRP in clinical and functional assessments and MRI images. Discussion. The use of technology to accelerate and improve the processes of tissue repair and integration is of great interest in repairing the ACL. Studies in humans are rare, with low level of evidence and contradictory results. Although the limitations of this study, it seems to us that the use of growth factors has no advantages in the process of PT graft integration at 6 months. Conclusion. PRP doesn't seem to contribute to enhancement of the ligamentation process and articular rehabilitation when used as a step of BTB technique
