Purpose The aim of this study was to determine the anatomic, operative and biological factors that inluenced graft healing after single-bundle anterior cruciate ligament (ACL) reconstruction. Methods One hundred fourteen consecutive patients who underwent anatomic single-bundle ACL reconstruction with quadrupled hamstring tendon autografts between 2016 and 2019 were retrospectively analyzed. Ninety-four patients met the inclusion criteria with minimum follow-up of 12 months. Patients were evaluated with multiple clinical measurements, including International Knee Documentation Committee Subjective Knee Form (IKDC-SKF), Lyshom Scores, and Marx activity scale. To evaluate graft healing, the signal-to-noise quotient (SNQ) was measured at intra-articular graft and intratunnel integration were evaluated on magnetic resonance imaging (MRI) at one year after surgery. Potential factors afecting graft healing, including age, sex, body mass index, time from injury to surgery, posterior tibial slope, lateral femoral condyle ratio, notch width index, meniscal injury, remnant preservation, tunnel aperture locations, graft size, graft bending angle, graft/remaining notch volume ratio were evaluated for their association with graft SNQ value by stepwise regression analysis. Results A total of 94 patients were evaluated with mean follow-up 28.5 ± 9 months. Univariate regression analysis showed that posterior tibial slope, notch width index, remnant preserving procedure, high femoral tunnel, anterior tibial tunnel, graft bending angle, and graft/remaining notch volume ratio signiicantly associated with graft SNQ values. Multivariate regression analysis showed that lateral tibial slope, remnant preservation, and graft/remaining notch volume ratio were independent factors correlated with graft SNQ values. Also, the graft SNQ values was weakly correlated with femoral tunnel integration and Marx activity scale at one year. There was no correlation between graft SNQ values and IKDC-SKF and Lysholm scores. There was no correlation between graft SNQ values and International Knee Documentation Committee and Lysholm scores. Conclusions Tibial slope, remnant preservation and graft/remaining notch volume ratio were signiicant independent associated factors of graft SNQ value at one year. The graft SNQ values were also weakly correlated with femoral tunnel integration and the Marx activity scale. These factors should be taken into account for ensuring the ideal graft healing and for the return to sport decision-making. Level of evidence Level IV.
The present study has shown that the Turkish version of the RAPA was an easy-to-use, valid and reliable measure of physical activity among adults aged older than 50 years. This study has also provided considerable evidence about the test-retest reliability of the RAPA, which was not investigated in the original validation study.

Nowadays, the incidence of knee arthritis increases with the prolongation of human life and the increase in world population. As a result, total knee arthroplasty application rates increased and surgeons gained more experience. There have also been technical advances and total knee arthroplasty operations have been performed using better implants. However, despite these developments, the number and variety of complications are increasing. In addition to performing total knee arthroplasty correctly, it is now becoming more important to recognize complications that may or may develop. Variety of complications after total knee replacement; from minor skin problems to life-threatening complications. In this review article, we aimed to investigate early and late complications during and after total knee replacement surgery.
Purpose We aimed to analyze the clinical and functional outcomes of patients who underwent surgery or received conservative treatment to look into the impact of treatment methods on clinical outcomes. Methods A retrospective study was performed on 25 patients with a minimum one-year follow-up. Patients were divided into two groups based on joint and physis displacement measured on preop CT images. Patients with a displacement of > 2 mm underwent surgery, while those with a displacement of < 2 mm received conservative treatment. The clinical results were assessed using the Ankle-Hindfoot Scale developed by the American Orthopedic Foot and Ankle Society (AOFAS) and the Modified Weber Protocol (MWP). Results The sample consisted of 14 patients who underwent surgery and 11 patients who received conservative treatment. The surgical group had a mean follow-up of 36.79±14.43 months, while the conservative group had a mean follow-up of 31.82±13.55 months. The surgical and conservative groups had a postop 1st-year AOFAS score of 96.64±3.54 and 93.64 ± 4.69, respectively. The difference was statistically insignificant (p > 0.05), but the surgical group had higher scores numerically. The surgical and conservative groups had a postop 6th-month AOFAS score of 84.64±1.64 and 80.82±2.85, respectively. The difference was statistically significant (p < 0.05). Conclusion The results of both surgical treatment and conservative treatment are satisfactory. Especially, surgical treatment should not be avoided in patients requiring surgery with a displacement of more than 2 mm and surgeons may consider surgery for better clinical outcomes and earlier rehabilitation in the treatment of triplane fractures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
