RESUMEN
INTRODUCTION: The aim of this study was to investigate patient satisfaction and fulfilment of expectations after osteotomy around the knee at one year postoperatively, using patient-related outcome measures. MATERIALS AND METHODS: From the initial sample of 264 patients, a total of 132 patients (age 48y ± 11) were enrolled in this prospective study (response rate 49.3%). Data were collected using the Hospital For Special Surgery-Knee Surgery Expectations Survey (HFSS-KSES), items for satisfaction and the Knee injury and Osteoarthritis Outcome Score (KOOS) measures. At one year postoperative follow-up, an individualized questionnaire asked whether the specific person-related expectations had been fulfilled. RESULTS: Satisfaction was high with 83.2% of all participants at one year after surgery. A total of 78% of patients stated they would decide to do the surgery again. This decision was significantly associated with satisfaction, younger age and better KOOS scores scales before surgery for pain, activity and sports. We found high correlations between satisfaction and fulfilment of expectations for the HFES-KSES. Fulfilment of expectations one year after surgery was significantly associated with significant improvements in KOOS scales at one year post-operation. Expectations (1) "to get the knee back to normal status", (2) "improve ability to squat", (3) "improve ability to run", (4) "improve ability to kneel" had been fulfilled worst. A multiple linear regression model for satisfaction had an R2 = 0.797 of the variance. The most influential was the variable fulfilment of "maintain health" that had 70.7% of variance. CONCLUSIONS: The fulfilled expectation concerning an improvement of the ability to maintain health was the most influential parameter for satisfaction at one year post-osteotomy. Patients with better health status of the knee and younger age rated the surgery to be more positive and were also more likely to do the surgery again. This provides an indication for an earlier intervention, before the knee and overall health status becomes more detrimental. LEVEL OF EVIDENCE: Level II (Therapeutic study).

BACKGROUND: Rotator cuff lesions are a common shoulder pathology mainly affecting patients aged >50 years. This condition is accompanied by not only pain and loss of function but also impaired quality of life and psychological stress. A frequently employed treatment option is arthroscopic repair. But expectations regarding the outcome after surgery might differ between patients and surgeons and therefore lead to dissatisfaction on both sides. The aim of this study was to document patient expectations of a planned arthroscopic rotator cuff repair and compare the results with the assessment of shoulder surgeons. MATERIALS AND METHODS: A total of 303 patients and 25 surgeons were involved in this study. Patients with partial- or full-thickness tear of the rotator cuff scheduled for arthroscopic repair were included in this study. Preoperatively, they were asked to fill out questionnaires inquiring sociodemographic data, scores of the underlying pathology, as well as expectations regarding the operation with regard to pain relief, gain of range of motion and strength, as well as the effect on activities of daily life, work, and sports. Furthermore, 25 surgeons were surveyed on what they think their patients expected using the same standardized questions. RESULTS: Among the patients, 43.9% considered gain of range of motion to be the most important goal after rotator cuff repair, followed by pain relief (30.6%) and gain of force (13.7%). Among the surgeons, 72% believed pain relief to be the most important for their patient followed by movement (20%) and strength (8%). When asked which parameter was the most important to achieve after operation, for patients, movement was on first place, pain second, and strength third. For shoulder specialists, the ranking was pain, movement, and strength. Surgeons significantly overrated pain relief when ranking against movement compared with their patients. CONCLUSION: The expectations of patients regarding their operation differ from the surgeon's assessment. Whereas gaining range of motion was more important for patients, surgeons clearly voted for pain relief. Different expectations should therefore be discussed within the pretreatment interview and taken into account when planning the right therapy. This might lead to better satisfaction on both sides.

INTRODUCTION: High tibial osteotomy (HTO) is a valid and joint preserving surgical technique to treat medial degenerative osteoarthritis (OA) in young and active patients. A recent study shows that patients' expectations of osteotomy around the knee are high, but OA progression and potential conversion to a total knee arthroplasty (TKA) were underestimated. The aim of this study was to investigate surgeons' expectations of HTO and to compare the results to the patients' expectations and actual outcomes reported in the literature. METHODS: 461 surgeons were questioned online using the 'Hospital for Special Surgery Knee Surgery Expectations Survey (HFSS-KSES)' and a ten-item non-validated questionnaire to investigate the expectations of HTO. Two subgroups were formed to investigate differences regarding the surgeons' experience. Statistical analysis was performed using IBM SPSS Statistics. RESULTS: Surgeons' expectations of HTO were rated between very and little important with pain reduction being the most important item on the HFSS-KSES. Furthermore, 'improving the ability to walk', 'to perform daily activities', 'having confidence in the knee', and 'avoiding future degeneration' were rated of high importance. An important difference regarding the experience was the lower expectations on delay/prevention of TKA of less-experienced surgeons. CONCLUSION: Surgeons' expectations of HTO are high but nevertheless different to the patients' expectations reported in the literature. Also, expectations for the delay/prevention of TKA differed regarding the experience of surgeons. While pain reduction represents one of the most important items for surgeons and patients, the expected outcome regarding the delay/prevention of a TKA and returning to sports differs to the patients' expectations and to the actual outcome reported in the literature. This should be considered when performing the preoperative informed consent.

In children and adolescents, injuries of the ankle are seen frequently in routine practice. The fracture pattern is less dependent on the mechanism of injury than on the maturity of the growth plate. Therefore, a differentiation is made between fractures with open epiphyses and fractures with a closing growth plate in adolescents. The potential for growth-related spontaneous deformity correction is limited, so axial alignment especially in the frontal plane has to be achieved during initial treatment. In displaced articular fractures an anatomical reconstruction of the articular surface and stable osteosynthesis have to be achieved to minimize the risk of early osteoarthritis. Growth arrest is not always avoidable despite an ideal reconstruction and can occur in all fracture types; however, with optimal conservative or surgical treatment, iatrogenic damage of the epiphysis can be avoided thereby reducing the incidence of growth disorders as a complication of ankle fractures in children and growing adolescents.

PURPOSE: This study was conducted to investigate patients' expectations on high tibial osteotomies, distal femur osteotomies, and double-level osteotomies in different health-related domains. It was hypothesized that expectations are high in terms of capacity to work, pain relief, and restoring knee function. METHODS: A total of 264 patients (age 47 years ± 11 years) were enrolled in this study from March 2015 until May 2016 in seven specialized orthopaedic surgery departments. Data were collected via the Knee injury and Osteoarthritis Outcome Score, the Hospital for Special Surgery-Knee Surgery Expectations Survey, and a ten-item (non-validated) questionnaire to specifically ask about expectations of osteotomies around the knee 24-48 h prior to surgery. In addition, self-efficacy was assessed. Parametric tests were used to test the hypothesis. RESULTS: Knee injury and Osteoarthritis Outcome Score test results showed that all patients suffered because of their knee impairments prior to surgery. All participants had high expectations in all aspects regarding the surgical outcome: on a four-point Likert scale ranging from 1 (very important) to 4 (not important), all mean values were between 1.2 and 1.7. For patients who had a demanding physical work, the ability to keep a stressful working posture was more important than for other patients (i.e. to kneel, to squat). Furthermore, preoperative lower quality of life was associated with higher expectations concerning improving the ability to walk, to achieve improvements in activities of daily living and social well-being. CONCLUSIONS: Patients' expectations of osteotomies around the knee are high in terms of capacity to work, pain relief, and restoring functions. The natural course of osteoarthritis and the potential need for conversion to TKA were underestimated by a substantial proportion of the study population. However, the expectation regarding survival rate is in line with the reported literature. The results of this study should assist surgeons in discussing realistic expectations when considering and counselling patients regarding osteotomies around the knee. This may help to clarify realistic expectations preoperatively and ultimately improve patients' satisfaction. LEVEL OF EVIDENCE: Therapeutic study, Level II.

PURPOSE: To analyze and compare patient expectations of primary and revision shoulder stabilization and to assess the factors associated with patients' expectations. METHODS: Pre-operative patient expectations after shoulder instability repair were prospectively assessed using a self-designed questionnaire. The survey included questions on the expected level and type of return to sports, instability, pain, risk of osteoarthritis, and overall shoulder condition. RESULTS: One-hundred and forty-five patients (99 primary; 46 revision repair) were included. A return to sport at the same level with slight to no restrictions was expected in 95%, a return to high-risk activities in 34%, to moderate in 58%, and to low-risk activities in 9%. No pain [instability] independent of the activity level was expected by 71% [79%] and occasional pain [instability] during contact and overhead activities by 25% [19%]. 61% expected to have no risk of glenohumeral osteoarthritis, 37% a slight, and 2% a significant risk. The overall expectation for the post-operative shoulder was indicated to be normal or nearly normal in 99% of patients. The revision group did not differ from the primary repair group in any variable. High pre-operative sport performance was positively correlated with post-operative sport expectations. The number of dislocations, the duration of instability, and the subjective instability level were negatively correlated with return to sport expectations. CONCLUSION: Patient expectations for primary and revision shoulder instability repair are high. Realistic patient expectations regarding the surgical procedure are necessary to avoid low patient satisfaction, especially in pre-operatively highly active and demanding athletes. The surgeon must not solely base the treatment on the pathology and possible risk factors for failure but should also take the individual expectation of the patient into account.

PURPOSE: To prospectively monitor health-related quality of life and return to work after arthroscopic anterior cruciate ligament (ACL) reconstruction in patients with isolated ACL tears. METHODS: Sixty consecutive patients with isolated ACL tears who underwent arthroscopic ACL reconstruction were prospectively monitored using the "Questions on Life Satisfaction Modules" (FLZM) and "Short-Form 12 (SF-12)" quality-of-life outcome measures. The Lysholm score and Tegner activity index were used as functional outcome measures. Additionally, return to work (months) together with level of physical workload was analysed. Outcome measures were assessed the day before surgery and at 6, 12 weeks and 6, 12, and 24 months post-operatively. Quality-of-life outcomes were correlated with functional outcome scores. RESULTS: Satisfaction with health (FLZM) significantly improved within the first 2 years (p < 0.05), and the physical component scale (SF12) showed a significantly higher score after 3, 6, 12 and 24 months as compared with preoperative values (p < 0.05). "General life satisfaction (FLZM)" was initially decreased at 6 weeks (p < 0.05) but increased during the further follow-up period, reaching a score not significantly different from preoperative values. Mean Lysholm score improved from 66 preoperatively to 89 post-operatively (p < 0.05) and the median Tegner activity index improved from four to six points (p < 0.05) at final follow-up. Mean time to return to work was 7 weeks (range 1-34 weeks), and it strongly depended on physical workload. A positive correlation between quality of life and functional outcome (Lysholm score) was observed. CONCLUSION: General life satisfaction is impaired during the early post-operative course, but returns to preoperative values after 2 years. Satisfaction with health reaches higher values after 6, 12 and 24 months post-operatively, and the SF-12 physical component scale was seen to improve during the follow-up period. Improved functional outcomes were observed to correlate with quality-of-life measurements. Thus, patients can preoperatively be informed that they will benefit from ACL reconstruction in terms of an improved knee function and satisfaction with health. Heavy physical workload must be considered as a risk factor for prolonged time lost to return to work. These patients have to be identified and informed about realistic expectations.

BACKGROUND: Fractures of the humeral greater tuberosity (GT) are a frequent injury progressively treated with arthroscopic suture anchor repair. Yet, no biomechanical study has been performed comparing fixation strength of arthroscopic single- (SR) vs. double row (DR) fixation. METHODS: Standardized fractures of the greater tuberosity were created in 12 fresh frozen proximal humeri. After random assignation to the SR or DR group the fixed humeri were tested applying cyclic loading to the supraspinatus and infraspinatus tendon. Load to failure and fragment displacement were assessed by means of an electrodynamic material testing machine using an optical tracking system. RESULTS: Load to failure values were higher in the DR group (649 N; ±176) than in the SR group (490 N; ±145) however without statistical significance (p = .12). In greater tuberosity displacement of 3-5 mm surgical treatment is recommended. The fixing constructs in this study did not reach displacement landmarks of 3 or 5 mm before construct failure as shown in previous studies. Thus the applied traction force (N) at 1 mm displacement was analyzed. In the SR group the load at 1 mm displacement was 277 N; ±46 compared to 260 N; ±62 in the DR group (p = .65). CONCLUSION: The results suggest that both techniques are viable options for refixation of greater tuberosity fractures. LEVEL OF EVIDENCE: Laboratory study.

PURPOSE: To report general life and health satisfaction after arthroscopic Bankart repair in patients with post-traumatic recurrent anterior glenohumeral instability and to investigate postoperative time lost to return to work at 2-year follow-up. METHODS: Between 2011 and 2013 patients treated with arthroscopic Bankart repair in the beach chair position for acute shoulder instability were included in this study. Questions on Life Satisfaction Modules (FLZM) and the Short Form 12 (SF-12) were used as quality-of-life outcome scales. Oxford Instability Score (OIS), Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), and self-reported American Shoulder and Elbow Surgeons (ASES) shoulder index were used as functional outcome scales. Return to work (months) was monitored and analyzed depending on physical workload. Data were assessed the day before surgery and prospectively monitored until 24 months postoperatively. Quality-of-life outcome was correlated with functional shoulder outcome and compared with normative age-adjusted data. Paired t-test, Wilcoxon test, Mann-Whitney U-Test, and Spearman's correlation coefficient were used for statistical analysis. RESULTS: Fifty-three patients were prospectively included. The mean age at surgery was 29.4 years. Satisfaction with general life and satisfaction with health (FLZM) as well as physical component scale (SF-12) improved significantly to values above normative data within 6 to 12 months after surgery (each P < .001). OIS, QuickDASH, and ASES improved significantly from baseline until 24 months after surgery (each P < .001). For ASES, improvement above minimal clinically important difference was shown. There was a positive correlation between quality of life and functional outcome scores (P < .05; rho, 0.3-0.4). Mean time to return to work was 2 months (range, 0-10; standard deviation, 1.9), with significantly longer time intervals observed in patients with heavy physical workload (3.1 months; range, 0 to 10; standard deviation, 2.4; P = .002). CONCLUSIONS: Following arthroscopic Bankart repair, quality of life was impaired during early course after surgery and increased significantly above preoperative levels within 6 to 12 months after the procedure. A steady state of excellent quality-of-life and functional outcomes was noted after 12 months of follow-up. Quality-of-life outcome scales correlated significantly with the functional outcome. Heavy physical workload must be considered as a risk factor for prolonged time lost to return to work. LEVEL OF EVIDENCE: Level III, prospective noncomparative therapeutic case series.

PURPOSE: (1) To monitor longitudinal changes in health-related quality of life (HRQOL), pain, knee function, and return to work (RtW) following high tibial osteotomy (HTO) for medial compartment osteoarthritis (OA), and (2) to investigate the influences of psychopathological comorbidities on preoperative impairment and post-operative course. METHODS: Sixty-four patients were prospectively followed for 24 months after HTO to determine HRQOL, pain, functional outcome, and RtW. Psychopathological comorbidities (e.g. depression) were determined preoperatively. Patients with no psychological distress (ND) were compared to patients with psychological distress (PD) in order to investigate the influence of psychopathological comorbidities on outcome. RESULTS: There was a significant increase in HRQOL and decrease in pain from 6 month follow-up on. Functional outcomes increased significantly from 12 month follow-up on. In general, there was a steady state of outcomes from 6- to 12-month follow-up on. At final follow-up, 90 % returned to their previous occupation without limitations. Mental component summary (MCS) and functional outcome showed a positive correlation with RtW, while depression had a negative one. A significantly inferior outcome of group PD versus ND was observed at baseline and early follow-up. RtW was significantly prolonged in group PD (8.9 ± 7.6 vs. 3.9 ± 3 months; p < 0.001). At final follow-up, both groups presented with comparable outcomes. CONCLUSION: HTO for medial compartment OA significantly improves HRQOL, pain, and knee function. Time to RtW is high and critically depends on PD. Further, extend of preoperative impairments, an initially inferior course, and inferior MCS outcome was influenced by PD. However, otherwise no significant differences were observed between groups PD and ND at final follow-up. LEVEL OF EVIDENCE: Prospective case series, II.

PURPOSE: To prospectively evaluate the prevalence and characteristics of meniscal injuries in children and adolescents undergoing surgical treatment for tibial eminence fractures and to test for possible relationships between associated meniscal lesions and patient demographics or injury characteristics. METHODS: A prospective multicenter study was conducted to arthroscopically assess the prevalence and characteristics of meniscal injuries in children and adolescents undergoing surgical treatment for tibial eminence fractures between 04/2014 and 10/2015. Patient demographics and injury characteristics were assessed preoperatively. The presence of a meniscal injury was evaluated arthroscopically and characterized according to tear type and location (Cooper classification). Patients with and without meniscal injuries were compared with regard to sex, age, height, weight, BMI, type of injury, mechanism of injury, time to surgery, Tanner stage, sexual maturity (prepubescent vs. pubescent), and modified Meyers and McKeever classification. RESULTS: A total of 54 consecutive patients (65 % males, mean age: 12.5 ± 3.2 years) were enrolled. Meniscal injury were found in 20 patients (37 %). The lateral meniscus was involved in 18 patients (90 % of all meniscus injuries) and the medial meniscus in 2 patients (10 % of all meniscus injuries). The most common tear pattern was a longitudinal tear of the posterior horn of the lateral meniscus (30 % of all meniscus injuries) and the second most common tear was a root detachment of the anterior horn of the lateral meniscus (20 % of all meniscus injuries). Higher age, advanced Tanner stage, and pubescence were significantly associated with an accompanying meniscal injury. CONCLUSION: Meniscal injuries in children and adolescents undergoing surgical treatment for tibial eminence fractures must be expected in almost 40 %, with a higher prevalence with increasing age and sexual maturity. With regard to the clinical relevance, the results of the present study argue in favor for magnetic resonance imaging prior to surgery in every patient with a suspected tibial eminence fracture and for an arthroscopic approach to adequately diagnose and treat meniscal injuries.

BACKGROUND: Open wedge high tibial osteotomy (HTO) is an established method for the treatment of patients with varus malalignment and medial compartment osteoarthritis. In these patients, health-related quality of life (HRQL) can be improved by using this procedure. The purpose of the present study consisted in evaluating HRQL up to 18 months after HTO, comparing the results to values of the German normal population, and in analyzing the impact of preoperative HRQL on the postoperative clinical result. It was hypothesized that normal values in physical and mental health can be achieved within 18 months after operation. STUDY DESIGN: Prospective case series. LEVEL OF EVIDENCE: IV. METHODS: 120 patients were included in this prospective case series from 12/2008 to 12/2011. All patients underwent open wedge HTO without a bone graft using the TomoFix(TM) plate. HRQL was assessed by using the SF-36 questionnaire, preoperatively, as well as 6, 12, and 18 months postoperatively. Regular scoring, norm-based scaling, and the physical and mental component summary scores (PCS and MCS) were evaluated. Clinical outcome was assessed by using Lequesne, Lysholm, HSS and IKDC Score. RESULTS: HRQL could be described in 96 patients. The PCS of HRQL showed a statistically significant pre- to postoperative improvement (30.2 ± 13.4 to 45.9 ± 13.5 after 18 months). A reduced preoperative mental component summary score (MCS) resulted in lower values of each clinical score (p < 0.05) and in a prolonged duration of incapacity for work (MCS < 50:15.0 ± 12.8 weeks, vs. MCS ≥ 50: 9.1 ± 4.8 weeks, p < 0.05). MCS values improved from the pre- to postoperative measurements and comparable values to the normal population were reached already within 6 months after surgery (46.0 ± 14.9 pre-operatively and 48.5 ± 13.7 after 6 months), and after 18 months even a score of 49.5 ± 12.4 was achieved. CONCLUSION: Lower preoperative mental component score results in reduced postoperative clinical outcome and prolonged duration of incapacity for work after HTO. In contrast to PCS, MCS showed comparable values to the normal population within 6 months after HTO.

BACKGROUND: In addition to Bankart repair engaging Hill-Sachs defects in glenohumeral instability have been treated successfully with remplissage procedure. The purpose of this study was to compare three remplissage techniques regarding (I) ability of preventing Hill-Sachs defect from engaging, (II) influence on glenohumeral rotational torque, and (III) resulting tendon coverage over the Hill-Sachs defect. METHODS: Standardized engaging Hill-Sachs defects and Bankart lesions were created in n = 7 fresh frozen human shoulder specimens. Besides Bankart repair three remplissage techniques (T) with double anchor position in the valley of the defect zone were studied: T1, knots tied over anchors; T2, knots tied between anchors (double-pulley); T3, knotless anchors with a suture tape. A parallel position-orientation and force-moment controlled navigated roboticsystem was used to compare prevention of Hill-Sachs defect engagement and torque [Nm]. Pressure sensitive film was used to study area of infraspinatus tendon coverage over Hill-Sachs defect [%]. RESULTS: All remplissage techniques prevented engagement of the Hill-Sachs defect without showing any construct failures. Regarding humeral torque there were significant impairments observed between intact conditions and the three investigated repair techniques in 60° abduction and ≥30° external rotation (p < .04). There was no significant difference in torque between intervention groups (n.s.). With a mean coverage of 26.8 % over the defect zone the knotless suture tape technique (T3) significantly improved area of soft tissue coverage compared to the other techniques (p = .03). CONCLUSION: All remplissage techniques prevented engagement of the Hill Sachs defect. With high abduction and external rotation ≥30° all techniques showed significant higher humeral torque compared to the intact specimens, while there was not one technique superior over the others. The suture tape technique conferred the largest and most effective area of tendon coverage over the Hill-Sachs defect zone. Long-term success of the remplissage procedure can possibly be enhanced by increasing the interface area of tendon coverage over the Hill-Sachs defect. Clinical studies will be necessary to proof potential benefits for clinical outcome.

PURPOSE: To biomechanically compare the stability of the coracoid process after an anatomic double-tunnel technique using two 4-mm drill holes or a single-tunnel technique using one 4-mm or one 2.4-mm drill hole. METHODS: For biomechanical testing, 18 fresh-frozen cadaveric scapulae were used and randomly assigned to one of the following groups: two 4-mm drill holes (group 1), one 4-mm drill hole (group 2), or one 2.4-mm drill hole (group 3). After standardized coracoid drilling, load was applied to the conjoined tendons at a rate of 120 mm/min and ultimate failure load, along with the failure mode, was recorded. RESULTS: There was no significant difference between groups regarding load to failure. Mean load to failure in group 1 was 392 N; group 2, 459 N; and group 3, 506 N. The corresponding P values were .55, .74, and .20 for group 1 versus group 2, group 2 versus group 3, and group 1 versus group 3, respectively. However, the failure mode for the group with one 4-mm drill hole and the group with two 4-mm drill holes was coracoid fracture, whereas the group with one 2.4-mm drill hole showed 5 tears of the conjoined tendons and only 1 coracoid fracture (P = .015). CONCLUSIONS: Although there was no significant difference regarding load-to-failure testing between groups, the failure mechanism analysis showed that one 2.4-mm drill hole led to less destabilization of the coracoid than one or two 4-mm drill holes. CLINICAL RELEVANCE: Techniques with small, 2.4-mm drill holes might decrease the risk of severe iatrogenic fracture complications.

PURPOSE: To evaluate sporting activity following osteochondral autologous transfer (OAT) combined with valgus high tibial osteotomy (HTO) in young and active patients with focal osteochondral defects of the medial femoral condyle and concomitant varus malalignment. METHODS: Thirty patients with focal osteochondral defects of the medial femoral condyle and varus malalignment >2° were enrolled. All patients were active in sports on a regular base prior to surgery (lifetime), but were unable to perform sports at the time of surgery. Sporting activity 1 year preoperatively and at final follow-up was compared using a previously published sports questionnaire, which assesses sports level, number of sports disciplines, sports frequency, sports duration and the participation in 32 common sports disciplines. Additionally, the Tegner activity scale and the Activity Rating Scale were used. RESULTS: After a mean follow-up of 6.9 years (2.5-9.8; SD 2.4), 76.7 % of patients were participating in sports on a regular basis (Fig. 2). Compared to 1 year preoperatively, there was no difference (n.s.) with regard to sports, the number of sports disciplines, sports frequency and sports duration (Fig. 4). The median Tegner activity scale measured preoperatively 5.0 (2.0-7.0) and post-operatively 5.0 (4.0-7.0) points (Fig. 3), and the ARS changed from 5.7 to 5.3 points (n.s.). The different types of sports disciplines were comparable between 1 year preoperatively and at follow-up. CONCLUSION: A high return to sports rate and an activity level comparable to the state at 1 year preoperatively can be expected in young and active patients after combined OAT and valgus HTO. This seems to be relevant in clinical practice when planning, indicating and performing these complex procedures. LEVEL OF EVIDENCE: IV.

PURPOSE: Unrealistic patient expectations have been shown to negatively influence patient-reported outcomes in orthopaedic surgery. Knowledge about patient expectations is important to associate preoperative expectations with the reasonable outcome of a specific procedure. The purpose of this study was to prospectively analyse and to compare patient expectations of primary and revision anterior cruciate ligament reconstruction (ACLR) and to assess the factors associated with patient expectations. METHODS: Preoperative expectations of 181 consecutive patients undergoing ACLR were assessed prospectively using a 5-item questionnaire. Primary ACLR (P-ACLR) was performed in 133 patients (73%), whereas 48 patients (27%) underwent revision ACLR (R-ACLR). The questionnaire assessed the expectation of the overall condition of the knee joint, return to sports, instability, pain, and risk of osteoarthritis. RESULTS: All patients expected a normal (38%) or nearly normal (62%) condition of the knee joint. Return to sports at the same level was expected by 91%. With regard to instability (pain), no instability (pain) independent of the activity level was expected by 77% (58%). No or only a slightly increased risk of the development of osteoarthritis was expected by 98%. The R-ACLR group showed a significantly lower expectation of the overall condition (p = 0.001), return to sports (p < 0.001), and pain (p = 0.002). No statistically significant difference was found between female and male patients (n.s.). In the P-ACLR group, patients with a history of previous knee surgery showed inferior expectations of return to sports (p = 0.015) and risk of osteoarthritis (p = 0.011). Age, number of previous knee surgeries, and pre-injury sports level significantly influenced patient expectations. CONCLUSIONS: Overall, patient expectations of ACL reconstruction are high. Patients undergoing revision ACL reconstruction have lower but still demanding expectations. Younger patients, patients without a history of knee surgery, and highly active patients have higher expectations. Explicit patient information about realistic goals of ACL reconstruction seems to be necessary in order to prevent postoperative dissatisfaction despite a successful operation in the surgeons' point of view. LEVEL OF EVIDENCE: Prospective case series, Level IV.

PURPOSE: The purpose of this study was to collect detailed data on postoperative sporting activity after arthroscopic Bankart repair for chronic shoulder instability. METHODS: Of 113 patients who underwent arthroscopic Bankart repair between February 2008 and August 2010, 81 met the inclusion criteria and were surveyed by a specially designed postal sport-specific questionnaire. Of these 81 patients, 66 (82%) were available for evaluation. RESULTS: All previously active patients performed some activity at follow-up. Of 9 patients (56%) who had been inactive, 5 took up new activities postoperatively. Forty-four patients (66%) stated that surgery had (strongly) improved their sporting proficiency. Seventeen patients (26%) reported no impact, and 5 patients (8%) reported a further deterioration compared with preoperatively. The improvement in sporting proficiency was negatively correlated with the preoperative risk level (ρ = 0.42, P < .001), preoperative performance level (ρ = 0.31, P = .012), and preoperative Tegner scale (ρ = 0.36, P = .003), as well as hours of sporting activity per week (ρ = 0.25, P = .042), whereas age showed a positive correlation (ρ = 0.28, P = .023). There was no change in duration, frequency, number of disciplines, Tegner activity scale, risk category, or performance level. CONCLUSIONS: Arthroscopic Bankart repair provides a high rate of return to activity among patients treated for chronic shoulder instability. A number of previously inactive patients returned to activity postoperatively. However, one-third of patients reported no benefit from surgery in terms of sporting activity. The improvement in sporting proficiency was highly dependent on the demands on the shoulder in sports, as well as the age of the patient. Overall, there was no significant increase in duration, frequency, number of disciplines, Tegner activity scale, or performance level between preoperative and follow-up evaluation and no increased return to high-risk activities. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Injuries of the meniscus roots have become increasingly recognised as a serious pathology of the knee joint. However, the current available literature focuses primarily on posterior meniscus root tears. In this article, a case with an isolated avulsion of the anterior medial meniscus root is presented, and a new arthroscopic technique to treat this type of injury is described. The anterior horn of the medial meniscus was sutured with a double-looped nonabsorbable suture and reattached to the tibial plateau using a knotless suture anchor. This technique may also be useful to treat avulsion injuries of the anterolateral or posteromedial meniscus root, and symptomatic subluxation of the medial meniscus in case of a variant insertion anatomy with an absent attachment of the anterior horn of the medial meniscus to the tibial plateau.
