Potential Risk Factors

Aims and Objectives: Distal femoral or tibial fractures as well as anterior cruciate ligament (ACL) tears can be associated with postoperative arthrofibrosis of the knee. So far, there are only a few studies that analyse this entity. The aim of the study is to evaluate potential risk factors that influence the outcome of patients with arthrofibrosis. We hypothesize that early arthroscopic arthrolysis is associated with a better postoperative outcome. Materials and Methods: 100 patients (at the time of the abstract submission n=59) with arthroscopic arthrolysis of postoperative arthrofibrosis of the knee were included in the retrospective study. They were clinically examined with a minimum follow-up of 2 years (mean 25±6 months). Arthrofibrosis was shown in 51% of the cases after ACL lesions, in 14% after femoral and tibial fractures, in 12% after infection and in 10% after patella fractures. The study population was divided into early (less than 3 months; n=19, mean 1.5 months) and late (more than 3 months; n=40, mean 8.7 months) arthroscopic arthrolysis after primary surgery. Results: In 51% of the cases (n=30) a normal range of motion could be postoperatively achieved (extension/flexion 0/140°). Patients with early arthroscopic arthrolysis showed significant more often a normal postoperative range of motion in comparison to patients with late revision (84% vs. 35%; p<0.001). Furthermore, patients with early arthrolysis had a significant lower postoperative flexion deficit than the late arthrolysis group (4° vs. 27°, p<0.001). The postoperative extension deficit was also significantly lower in the early arthrolysis group (0.4° vs. 3°; p=0,021). Postoperative functional scores were significantly higher after arthroscopic arthrolysis in comparison to before arthrolysis (Lysholm 85,1±11 vs. 41,3±9, p=0,049; Tegner 6,1±1 vs. 3,2±2, p=0,035; Cincinnati Rating Scale 83,1±13 vs. 52,1±16, p=0,046). Conclusion: Arthrofibrosis of the knee can be successfully treated with arthroscopic arthrolysis. Good postoperative results can be gained in treating flexion and extension deficits. Early arthroscopic arthrolysis shows significant better results in postoperative range of motion in comparison to late arthroscopic arthrolysis.

Lost To Follow Up

Abstract Purpose Impaired patient outcome can be directly related to a loss of motion of the knee following surgical procedures. If conservative therapy fails, arthroscopic arthrolysis is an effective procedure to improve range of motion (ROM). The purpose of this study was to evaluate the outcome of patients undergoing very early (< 3 months), early (3 to 6 months), and late (> 6 months) arthroscopic arthrolysis of the knee. Methods With a follow-up on average at 35.1 ± 15.2 (mean ± SD, 24 to 87) months, 123 patients with post-operative motion loss (> 10° extension deficit/ < 90° of flexion) were included between 2013 and 2018 in the retrospective study, while eight patients were lost to follow-up. A total of 115 patients were examined with a minimum follow-up of two years. Twenty percent (n = 23) of patients of this study population had a post-operative motion loss after distal femoral fracture, 10.4% (n = 12) after tibial head fracture, 57.4% (n = 66) after anterior/posterior cruciate ligament (ACL/PCL) reconstruction, 8.7% (n = 10) after infection of the knee, and 3.4% (n = 4) after patella fracture. Thirty-seven patients received very early (< 3 months, mean 1.8 months) arthroscopic arthrolysis, and 37 had early (3 to 6 months, mean 4.3 months) and 41 late (> 6 months, mean 9.8 months) arthroscopic arthrolysis after primary surgery. Results The average ROM increased from 73.9° before to 131.4° after arthroscopic arthrolysis (p < 0.001). In the group of very early (< 3 months) arthroscopic arthrolysis 76% (n = 28) of the patients had a normal ROM (extension/flexion 0/140°), in the group of early (3–6 months) arthrolysis 68% (n = 25) of the patients and in the group of late arthrolysis 41.5% (n = 17) of the patients showed a normal ROM after surgery (p = 0.005). The total ROM after arthrolysis was also significantly increased in the group of very early and early arthrolysis (136.5° and 135.3° vs. 123.7°, p < 0.001). A post-operative flexion deficit occurred significantly less in the group of very early and early arthroscopic arthrolysis compared to the late arthroscopic arthrolysis (3.9° and 4.2° vs. 16.6°, p < 0.001). Patients treated with very early (< 3 months) and early (3 to 6 months) showed a significantly increased post-operative Tegner score of 4.8 ± 1 and 4.7 ± 1.1 compared to 3.8 ± 1.1 in the group of late arthroscopic arthrolysis (> 6 months, p < 0.001). Conclusions An arthroscopic arthrolysis is highly effective and leads to good to excellent mid-term results. An early arthroscopic arthrolysis within 6 months after primary surgery leads to significantly improved ROM and functional scores compared to the late arthrolysis (> 6 months).

Background: Cyclops syndrome is characterized by a symptomatic extension deficit attributed to impingement of a cyclops lesion within the intercondylar notch. The syndrome is an important cause of reoperation after anterior cruciate ligament reconstruction (ACLR). It has been suggested that remnant-preserving ACLR techniques may predispose to cyclops syndrome, but there is very limited evidence to support this. In general terms, risk factors for cyclops syndrome are not well-understood. Purpose: To determine the frequency of and risk factors for reoperation for cyclops syndrome in a large series of patients after ACLR. Study Design: Case-control study; Level of evidence, 3. Methods: A retrospective analysis of prospectively collected data was performed, including all patients who underwent primary ACLR between January 2011 to December 2017. Patients undergoing major concomitant procedures were excluded. Demographic data, intraoperative findings (including the size of preserved remnants), and postoperative outcomes were recorded. Those patients who underwent reoperation for cyclops syndrome were identified, and potential risk factors were evaluated in multivariate analysis. Results: A total of 3633 patients were included in the study, among whom 65 (1.8%) underwent reoperation for cyclops syndrome. Multivariate analysis demonstrated that preservation of large remnants did not predispose to cyclops lesions (odds ratio [OR], 1.11; 95% CI, 0.63-1.93). The most important risk factor was extension deficit in the early postoperative period. If present at 3 weeks postoperatively, it was associated with a >2-fold increased risk of cyclops syndrome (OR, 2.302; 95% CI, 1.268-4.239; P < .01), which was increased to 8-fold if present 6 weeks after ACLR (OR, 7.959; 95% CI, 4.442-14.405; P < .0001). None of the other potential risk factors evaluated were found to be significantly associated with an increased frequency of cyclops syndrome. Conclusion: Failure to regain full extension in the early postoperative period was the only significant risk factor for cyclops syndrome after ACLR in a large cohort of patients. Other previously hypothesized risk factors, such as preservation of a large anterior cruciate ligament remnant, did not predispose to the development of this debilitating postoperative complication.

Background: Non-hemorrhagic stroke patients experience hemiparesis, an improper handling results in joint contractures. Discharge planning combined with a range of motion (ROM) training given to patients and their families are expected to improve muscle strength in patients after returning from the hospital. Aims: This study is to identify the effectiveness of discharge planning in increasing muscle strength. Methods: This is a quasi-experimental study with a pre-posttest design. A total of 34 respondents were selected by cluster random sampling technique, from RAA Soewondo Pati General Hospital of Pati, Central Java, Indonesia. The respondents were divided equally into two groups; an intervention group (N = 17) was given a discharge planning program together with stroke information and range of motion (ROM) training while the control group (N = 17) received a standard discharge planning available in the hospital. Further, Muscle Rating Scale (MRS) was employed to assess the muscle strength on the 2nd, 7th, and 14th day after discharge planning presented to the nonhemorrhagic stroke patients. Results: This present study clearly acknowledges the standard discharge planning program available in the hospital improve the muscle strength of the upper and lower extremity in the nonhemorrhagic stroke patients just 2nd day after the care (pretest), and the significant improvement was observed until the day 14. Moreover, combining the care with ROM training at the intervention group faster the recovery and the muscle strength improved significantly at the 7th day and continue increase at the day 14. Looking to the muscle strength since the 2nd day to the day 14, respectively the muscle strength of upper and lower limb at the control group improved at the point of 0.588 and 0.882, while at the group received the ROM training reached the value of 1.472 and 1.412. Conclusions: The ROM training combined to the current discharge planning program will faster the muscle strength recovery of the nonhemorrhagic stroke patients. This research provide insight how family plays important role to the success in monitoring the rehabilitation and recovery progress.

Study design: Prospective comparative cohort study. Objectives: The study aims to elucidate the relationship between Modic endplate changes and clinical outcomes after a lumbar microdiscectomy. Methods: Consecutive patients undergoing microdiscectomy for lumbar disc herniation (LDH) were prospectively studied. Pre-operative clinical and radiological parameters were recorded. The pain was assessed by Numeric pain rating scale (NPRS), and functional assessment by Oswestry Disability Index (ODI). Minimal clinically important difference (MCID) in outcome was calculated for both the groups. Complications related to surgery were studied. Follow-up was done at 6 weeks, 3 months, 6 months and 1 year. Mac Nab criteria were used to assess patient satisfaction at 1 year. Results: Out of 309 patients, 86 had Modic changes, and 223 had no Modic changes. Both groups had similar back pain (p-value: 0.07) and functional scores (p-value: 0.85) pre-operatively. Postoperatively patients with Modic changes had poorer back pain and ODI scores in the third month, sixth month and 1 year (p-value: 0.001). However, MCID between the groups were not significant (p-value: 0.18 for back pain and 0.58 for ODI scores). Mac Nab criteria at 1 year were worse in Modic patients (p-value: 0.001). No difference was noted among Modic types in the pre-operative and postoperative pain and functional outcomes. Four patients in Modic group (4.7%) and one patient in the non-Modic group (0.5%) developed postoperative discitis (p-value: 0.009). Conclusions: Preoperative Modic changes in lumbar disc herniation is associated with less favorable back pain, functional scores and patient satisfaction in patients undergoing microdiscectomy.

Background: Arthrofibrosis remains a concerning early complication after anterior cruciate ligament reconstruction (ACLR) in children and adolescents. Previous studies suggest that those receiving patellar tendon (PT) autograft may be at higher risk than hamstrings tendon (HT), but there is little data regarding this complication in patients receiving quadriceps tendon (QT) autograft. Purpose: The purpose of this study is to identify risk factors for arthrofibrosis following pediatric ACLR with attention to graft type. Methods: The medical records of patients that underwent primary ACLR at a single tertiary children’s hospital were reviewed for this retrospective cohort study. Those with multiligament reconstructions, lateral extra-articular tenodesis procedures, or a modified MacIntosh reconstruction were excluded. Arthrofibrosis was defined as a deficit of 10 degrees of extension and/or 20 degrees of flexion at 3 months after ACLR. Demographic data, intra-operative findings and techniques, and post-operative motion and complications were recorded. Univariate analysis was followed by purposeful entry logistic regression to control for confounding factors. Results: A total of 378 patients were included in the analysis, of which there were 180 PT, 103 HT, and 95 QT grafts. The mean age was 15.9±1.7 years and 188 (49.7%) were female. In univariate analysis, the rate of arthrofibrosis was 1.9% for HT, 6.3% for QT, and 10.0% for PT (p=0.04). Females developed arthrofibrosis more frequently than males (10.6% vs. 3.2%, p=0.004). Additionally, those that ultimately experienced this complication had lower median flexion at 6 weeks after ACLR (88 vs. 110 degrees, p<0.001). After controlling for covariates in a multivariate model, PT graft raised the odds of arthrofibrosis 6.2 times compared to HT (95% CI 1.4-27.6, p=0.02), but there were no significant differences between QT and other graft types. Females were at 4.2 times higher odds than males (95% CI 1.6-10.8; p=0.003). Patients that were unable to attain 90 degrees of flexion 6 weeks after ACLR had 14.7 times higher odds of eventually developing arthrofibrosis (95% CI 5.4-39.8; p<0.001). Finally, those with an extension deficit of ≥5 degrees 6 weeks after ACLR had 4.7 times higher odds of experiencing this complication (95% CI 1.8-12.2, p=0.001). Conclusion: After adjusting for multiple covariates, PT autograft, female sex, and motion deficits at 6 weeks after ACLR (<90 degrees of flexion or extension deficit ≥5 degrees) were predictive of arthrofibrosis in children and adolescents. Quadriceps tendon autograft did not increase the risk of this complication.

Background: Anterior knee pain is a frequent condition after anterior cruciate ligament reconstruction (ACLR), but its origin remains uncertain. Studies have suggested that donor site morbidity in autologous bone–patellar tendon–bone reconstructions may contribute to patellofemoral pain, but this does not explain why hamstring tendon reconstructions may also present with anterior pain. Purpose: To evaluate the prevalence of anterior knee pain after ACLR and its predisposing factors. Study Design: Case-control study; Level of evidence, 3. Methods: We evaluated the records of all patients who underwent ACLR between 2000 and 2016 at a private facility. The prevalence of anterior knee pain after surgery was assessed, and possible risk factors (graft type, patient sex, surgical technique, range of motion) were evaluated. Results: The records of 438 patients (mean age, 30 years) who underwent ACLR were analyzed. Anterior knee pain was found in 6.2% of the patients. We found an increased prevalence of anterior knee pain with patellar tendon graft, with an odds ratio of 3.4 ( P = .011). Patients who experienced extension deficit in the postoperative period had an odds ratio of 5.3 of having anterior pain ( P < .001). Anterior knee pain was not correlated with patient sex or surgical technique. Conclusion: The chance of having anterior knee pain after ACLR was higher when patellar tendon autograft was used compared with hamstring tendon graft, as well as in patients who experienced extension deficit in the postoperative period.

Context: Anterior cruciate ligament (ACL) injuries are a common and devastating injury in women’s soccer. Several risk factors for ACL injury have been identified, but have not yet been examined as potentially dynamic risk factors, which may change throughout a collegiate soccer season. Design: Prospective cohort study. Methods: Nine common clinical screening assessments for ACL injury risk, consisting of range of motion, movement quality, and power, were assessed in 29 Division I collegiate women’s soccer players. Preseason and midseason values were compared for significant differences. Change scores for each risk factor were also correlated with cumulative training loads during the first 10 weeks of a competitive soccer season. Results: Hip external rotation range of motion and power had statistically significant and meaningful differences at midseason compared with preseason, indicating they are dynamic risk factors. There were no significant associations between the observed risk factor changes and cumulative training load. Conclusions: Hip external rotation range of motion and power are dynamic risk factors for ACL injury in women’s collegiate soccer athletes. Serial screening of these risk factors may elucidate stronger associations with injury risk and improve prognostic accuracy of screening tools.

Knee Flexion Contracture

Background Heel-height difference has been used to detect subtle knee flexion contractures, but the effects of thigh circumference differences and patient positioning during testing have not been evaluated. Hypothesis Differences in thigh circumference measurements and whether the patient's patellae are on or off the examination table during heel-height difference measurement will not affect the accuracy of detecting knee flexion contracture. Study Design Prospective cohort study. Methods Bilateral knee range of motion, prone heel-height difference with the patellae on and off the table, and thigh circumference at 5 and 15 cm proximal to the proximal pole of the patella were measured by one investigator on 50 consecutive patients who had undergone unilateral anterior cruciate ligament reconstruction. Results A high degree of correlation was demonstrated between the heel-height difference and the standard range of motion measurement. Differences in thigh girth and patellar position did not statistically affect the accuracy of the heel-height difference as an indicator of knee flexion contracture. Conclusion Heel-height difference is a valid method of documenting knee flexion contractures. Compared with traditional goniometer assessment, this test is a more meaningful and easier way for detecting subtle knee flexion contractures of less than 10°.
