Background: Complications and adverse events after anterior cruciate ligament (ACL) reconstruction are well known, but they have been underestimated in previous studies. Purpose: To describe the complications and adverse events after ACL reconstruction within a 2-year follow-up and analyze them in relation to the type of graft. Study Design: Cohort study; Level of evidence, 3. Methods: From 2000 to 2012, 958 patients with an isolated ACL injury underwent surgery by a single knee surgeon. ACL reconstruction was performed with the medial portal technique for the femoral tunnel and the use of bone–patellar tendon–bone (BPTB) or hamstring tendon graft. Patients were reviewed at 6 weeks and 3, 6, 12, and 24 months after surgery with the International Knee Documentation Committee score, plain radiographs, and the KT-1000 arthrometer. Results: Of 958 patients enrolled, 147 (15%) were lost at last follow-up. The 2 groups (bone–patellar tendon–bone [n = 257] and hamstring [n = 554]) were similar regarding the mean age at the time of surgery and preoperative anterior laxity. The main complications were as follows: anterior knee pain (n = 130 of 811, 16%), stiffness (n = 72, 8.8%), secondary meniscal lesions (n = 59, 7.2%), pain attributed to fixation (n = 79, 9.7%), ACL rerupture (n = 47, 5.7%), contralateral ACL ruptures (n = 24, 3%), patellar fractures (n = 3, 0.3%), infections (n = 9, 1%), and thromboembolic complications (n = 5, 0.6%). There was no significant difference between the grafts with respect to the frequency of joint stiffness, secondary meniscal lesions, or anterior knee pain. During the first 2 postoperative years, the percentage of patients with anterior knee pain was higher in the patellar tendon group (23.3% vs 12.6%, P < .001); however, this difference was not significant after the 2-year interval (3.1% vs 2.5%, P = .63). The percentage of patients with a rerupture of the graft was significantly lower in the patellar tendon group than in the hamstring group (25 of 811 [3.1%] vs 57 of 811 [7%], P = .023). Similar results were recorded regarding the pain related to the hardware material (7 of 811 [0.8%] in the BPTB group vs 113 of 811 [13.9%] in the hamstring group, P = .001). The percentage of ACL ruptures contralateral to the repair was higher in the patellar tendon group (41 of 811 [5%] vs 17 of 811 [2%], P = .016). Conclusion: The total rate of complications after an ACL reconstruction was 39%, and the surgical revision rate for any reason was 28%. Problems with the hardware material were more frequent in the hamstring group, leading to an increased rate of surgical revision. Anterior knee pain was initially higher in the patellar tendon group, but there was no significant difference in a 2-year interval. The rerupture rate was statistically higher in the hamstring group.

Abstract Objectives: In this study, we retrospectively compare the clinical results, range of knee motion and anterior knee pain in patients on whom we performed knee arthroplasty with and without patellar resurfacing. Thirty-eight patients were evaluated in the study. Knee Society scores, knee range of motion and anterior knee pain before and 12 months after surgery were detected. Patients were divided into two groups: resurfaced patellas and nonresurfaced patellas. There were 18 patients in the resurfaced group and 20 patients in the nonresurfaced group. Mean Knee Society score was 40.72±13.09 in the resur-faced group and 38.55±5.88 in the nonresurfaced group before surgery. Mean Knee Society score was 80.38±7.78 in the resur-faced group and 80.10±3.22 in the nonresurfaced group in the last control. Mean knee range of motion was 92.83±12.12 degrees in the resurfaced group and 91.05±10.10 degrees in the nonresurfaced group before surgery. Mean range of motion was 106.22±9.13 degrees in the resurfaced group and 97.25±8.50 degrees in the nonresurfaced group after surgery. There were twelve patients with anterior pain before surgery in the resur-faced group and 13 patients with anterior knee pain before surgery in the nonresurfaced group. After surgery, there was one patient with anterior pain in the resurfaced group and 9 patients with anterior knee pain in the nonresurfaced group. Anterior knee pain ratio was smaller in the resurfaced group than in the nonresurfaced group, and there was a significant difference in range of knee motion as a result of our study. We offered to resurface the patella.

Abstract Introduction Anterior knee pain is one of the major problems in total knee arthroplasty (TKA) and is often etiologically associated with a patellofemoral parts etiology. There is no consensus as to etiology or treatment. Denervation of the patella by electrocautery and patelloplasty along with removal of osteophytes have been used for treatment of anterior knee pain in TKA. The purpose of our study was to compare, in terms of the anterior knee pain and clinical outcomes of patelloplasty in total knee arthroplasty (TKA), patellar denervation by electrocautery and non-patellar-denervation treatment in a 2 year follow-up. Materials and methods This study was conducted in a total of 108 patients, who underwent TKA at our institution between June 2015 and December 2016. Patients age 55 to 80 years, who are suffering from osteoarthritis, rheumatoid arthritis of knee were included in this study. Patients were randomly allocated into patelloplasty with denervation group and non-denervation group. The denervation of the patella was done in electrocautery group using a monopolar coagulation diathermy set to 50 W. (Valleylab Inc., Boulder, CO). Postoperatively, patients were assessed at regular intervals of 3, 6, 9, 12, 24 months. To assess patient outcomes, we used questionnaires to determine the Knee Society score (KSS - knee and function scores), a specific patellofemoral pain questionnaire (Kujala score) range of motion (ROM) and a visual analogue scale (VAS) to assess anterior knee pain. Results The data obtained were analyzed using SPSS version 17.0. Continuous variables were expressed as mean ± SD. Of the 108 patients, 9 patients were lost to follow-up. Among the remaining 99 patients, 50 were included in denervation group and 49 in non-denervation group. In our study, there was no statistically significant difference in Mean KUJALA score preoperatively (p > 0.05). Postoperatively, the mean KUJALA score was significantly higher in denervation group at 3, 6, 9, 12, 24 months of follow-up when compared to TKR with no denervation (p < 0.05). There was no statistically significant difference in Mean VAS score preoperatively (p > 0.05). However, 6, 12 and 24 months after the operation, the mean VAS score was significantly lower in denervation group. There was no statistically significant difference in Mean KSS score preoperatively and postoperatively (p > 0.05). The mean ROM was significantly higher in denervation group than in the group of TKR with no denervation (p < 0.05). Conclusion In our study, less postoperative anterior knee pain, increased range of motion, significantly lower VAS scores were seen in the denervation group compared with non-denervation group. Circumferential denervation of patella during primary TKA along with patellar resurfacing is a safe procedure that improves patient satisfaction, decreases anterior knee pain and improves range of flexion in the postoperative period and at postoperative follow-ups.

<p><strong><em>Outline: </em></strong><em>Anterior Knee Pain (AKP) is the most prevalent injury in running. Growing evidence suggests that hip muscle imbalance plays a role in the development of AKP. Gluteus Medius (GMed) is the main abductor of the hip and also stabilises the pelvis during gait. Studies show that hip-abduction strength is decreased in populations with AKP. This relates to increased hip-adduction, hip internal rotation and knee abduction, which are associated with higher patellofemoral contact pressures. <strong>Objective:</strong> The main aim of this study is to determine whether a standing exercise programme will improve hip-abductor strength. The second aim of the study is to determine whether there will be a decrease in running-related pain after completing a six-week standing exercise programme. </em></p><p><strong><em>Design: </em></strong><em>Within-participant pre-test/post-test comparative trial.</em></p><p><strong><em>Setting:</em></strong><em> The Sport’s Clinic at the Malta Football Association. Ta Qali National Stadium (Malta).</em></p><p><strong><em>Main outcome measures: </em></strong><em>GMed torque was measured using a Biodex® System 3 isokinetic dynamometer as demonstrated by Brent et al (2013). The Numerical Rating Scale was used to measure pain related to running. </em></p><p><strong><em>Results: </em></strong><em>Pre-test torque scores were higher on the affected side. Scores on the affected side improved by 22.81% from a mean baseline average of 96.00Nm/kg to 117.86Nm/kg, (p-value 0.013). Scores on the unaffected side improved by 27.97% from a mean baseline average of 90.14Nm/kg to 115.29Nm/kg (p-value 0.031). Post-test scores were more balanced between limbs. Pain scores decreased from 5.29 as measured on the NRS to 1.00 (p-value 0.000). </em></p><p><strong><em>Conclusion: </em></strong><em>Standing exercises aimed at strengthening the hip-abductors may prove to be a valid intervention for prevention and rehabilitation of AKP. However, better quality studies are needed in order to validate this.</em><em></em></p>

Aims The aim of this study was to compare the incidence of anterior knee pain after antegrade tibial nailing using suprapatellar and infrapatellar surgical approaches Patients and Methods A total of 95 patients with a tibial fracture requiring an intramedullary nail were randomized to treatment using a supra- or infrapatellar approach. Anterior knee pain was assessed at four and six months, and one year postoperatively, using the Aberdeen Weightbearing Test – Knee (AWT-K) score and a visual analogue scale (VAS) score for pain. The AWT-K is an objective patient-reported outcome measure that uses weight transmitted through the knee when kneeling as a surrogate for anterior knee pain. Results A total of 53 patients were randomized to a suprapatellar approach and 42 to an infrapatellar approach. AWT-K results showed a greater mean proportion of weight transmitted through the injured leg compared with the uninjured leg when kneeling in the suprapatellar group compared with the infrapatellar group at all timepoints at all follow-up visits. This reached significance at four months for all timepoints except 30 seconds. It also reached significance at six months at 0 seconds, and for one year at 60 seconds. Conclusion The suprapatellar surgical approach for antegrade tibial nailing is associated with less anterior knee pain postoperatively compared with the infrapatellar approach Cite this article: Bone Joint J 2019;101-B:1138–1143

Background: Phototherapy is crucially an important aspect for the management of most neonatal jaundice. Neonates are prone to develop bilirubin encephalopathy (kernicterus). LED phototherapy is a new option of managing neonatal jaundice. The objective of this study is to compare the efficacy and safety of LEDs with fluorescent phototherapy in the treatment of indirect hyperbilirubinemia.Method: The study was Experimental research design, prospective study. The Study was conducted at Neonatal unit of Shaheed Suhrawardy Medical College Hospital, Dhaka. Total sample size of the study was one hundred neonates. Fifty for conventional phototherapy and fifty for LED phototherapy. Purposive sampling method was used for the study. The data collection tool of the study was pretested structured questionnaire. The modes of presentation, the clinical examination and investigation findings at admission and during daily follow up were recorded for individual patient.Result: The rate of fall of S. bilirubin was more in those neonates who have had LED phototherapy. As a result, duration of phototherapy as well as hospital stay was less in LED group. Furthermore, higher number of neonates developed rashes in LED group than in conventional group with statistically significant difference. Of course, variables regarding other adverse events did not show any statistically significant difference between two groups.Conclusion: Management of neonatal jaundice may be more effective in LED phototherapy than conventional phototherapy. LED device require shorter duration of phototherapy, thus, shorter hospital stay.Bangladesh J Child Health 2018; VOL 42 (2) :62-66

Abstract Background Anterior knee pain (AKP) is the most common complication of total knee arthroplasty (TKA). It is unclear which procedure of addressing AKP is preferable. Some data suggest patellar denervation (PD) provides effective AKP prevention. The purpose was to assess the effectiveness and safety of PD in primary TKA.Methods A meta-analysis was performed of randomized clinical trials (RCTs) from inception to March 26, 2020, using PubMed, Embase, Web of Science and Cochrane Library. Study-specific RR and MD were aggregated using random or fixed effects models. The outcomes were incidences of AKP, PS (patellar scores), VAS (visual analogue scale), ROM (range of motion), KSS knee (American Knee Society knee scores), KSS function (American Knee Society function scores), incidence of complications and revisions.Results Ten RCTs involving 1196 knees were included. The meta-analysis showed no significant in PD group on the incidence of AKP (RR = 0.64; 95% CI 0.37, 1.11; p = 0.11) with moderate heterogeneity (P < 0.01, I2 = 84%). Our results indicated PD had a significantly better VAS (MD = − 0.25; 95% CI -0.41, -0.09; p < 0.01), ROM (MD = 7.68; 95% CI 0.34, 15.20; p = 0.04) and PS (MD = 0.91; 95% CI 0.36, 1.46; p < 0.01). However, there was no significant difference no matter in KSS knee, KSS function, complications or revisions.Conclusions This meta-analysis showed that no difference in AKP between PD and NPD in patients undergoing non-resurfaced TKA. PD could improve clinical outcome in VAS, post-operative ROM and PS.
