Abstract
BACKGROUND Uniform procedures for rehabilitation and follow-up treatment after injuries and surgeries at the upper extremity do not exist. Accordingly, only a few approaches for the follow-up treatment of instabilities of the elbow joint have been described. OBJECTIVES The authors show how rehabilitation before sport-specific training after rupture of the ulnar collateral ligament in a female handball player was objectivized and controlled using the results of functional tests. MATERIALS AND METHODS The follow-up treatment of a semi-professional female handball player (aged 20) after rupture of the ulnar collateral ligament was objectivized and controlled using the return to activity algorithm. In addition to the comparisons with the values of the unaffected side, comparative results of 14 uninjured female handball players were used for guidance. RESULTS/CONCLUSIONS The patient was able to participate fully in sport-specific training after 15 weeks and participate in her first competitive match after 20 weeks. On the affected side, she achieved a distance of 118% of her upper limb length on the medial reach of the upper quarter Y balance test and 63 valid contacts on the wall hop test. The values achieved at the end of rehabilitation were higher than the average values of the control group.

Assessment of Complication Risk in the Treatment of Proximal Humerus Fractures: A Retrospective Analysis of 4019 Patients. J Clin Med 2023; 12:jcm12051844. [PMID: 36902631 PMCID: PMC10003238 DOI: 10.3390/jcm12051844] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Revised: 01/22/2023] [Accepted: 02/21/2023] [Indexed: 03/03/2023] Open
Abstract
(1) Background: The treatment of proximal humeral fractures (PHFs) is debated controversially. Current clinical knowledge is mainly based on small single-center cohorts. The goal of this study was to evaluate the predictability of risk factors for complications after the treatment of a PHF in a large clinical cohort in a multicentric setting. (2) Methods: Clinical data of 4019 patients with PHFs were retrospectively collected from 9 participating hospitals. Risk factors for local complications of the affected shoulder were assessed using bi- and multivariate analyses. (3) Results: Fracture complexity with n = 3 or more fragments, cigarette smoking, age over 65 years, and female sex were identified as predictable individual risk factors for local complications after surgical therapy as well as the combination of female sex and smoking and the combination of age 65 years or older and ASA class 2 or higher. (4) Conclusion: Humeral head preserving reconstructive surgical therapy should critically be evaluated for patients with the risk factors abovementioned.

Patient response to osteotomy around the knee joint at one year post-operation-fulfilment of expectations and current health status. Arch Orthop Trauma Surg 2022:10.1007/s00402-022-04660-6. [PMID: 36344785 DOI: 10.1007/s00402-022-04660-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Accepted: 10/10/2022] [Indexed: 11/09/2022]
Abstract
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).

Abstract
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.

Different expectations of patients and surgeons with regard to rotator cuff repair. J Shoulder Elbow Surg 2022; 31:1096-1105. [PMID: 35149203 DOI: 10.1016/j.jse.2021.12.043] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 12/23/2021] [Accepted: 12/25/2021] [Indexed: 02/01/2023]
Abstract
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.

Abstract
Purpose To investigate, if patients with complex proximal tibial fracture have realistic expectations on open reduction and internal fixation. Methods 114 patients (mean 49 years, SD ± 13) with closed AO-type B and C proximal tibial fracture were grouped (group B, respectively C). Prior to surgery expectations concerning knee function, pain, return to work/sports, and the risk for osteoarthritis was assessed with the Hospital for Special Surgery-Knee Surgery Expectations Survey (HFSS-KSE) and a non-validated ten-item survey. Results 92% of patients expected at least an almost natural knee postoperatively. All items regarding restoring knee function were ranked to be at least important in both groups. 65% in group B and 47% in group C expected at most occasional pain. 83% in group B and 67% in group C expected full return to work without any limitations. Patients with low physical work intensity expected significantly shorter incapacity to work in both groups (7.8, respectively 8.9 weeks). 71% in group B and 60% in group C expected to return to sports with at most small limitations. 33% in group B and 22% in group C assumed risk for osteoarthritis will be prevented by surgery. Conclusion Expectations on surgery for complex proximal tibial fracture are high regardless of fracture type. The prognosis of many health and lifestyle domains was overestimated. The risk for osteoarthritis was underestimated. This study should sensitize surgeons to discuss realistic expectations. This may help to improve patient comprehension what leads to sensible expectations, resulting in improved patients´ satisfaction. Level of evidence IV.

Abstract
BACKGROUND The stabilization strategy for acute high-grade acromioclavicular (AC) joint separations with AC-stabilizing clavicular hook plate (cHP) or coracoclavicular (CC)-stabilizing double double-button suture (dDBS) is still under consideration. HYPOTHESIS The CC-stabilizing dDBS is superior to the cHP according to an AC-specific radiologic assessment and score system. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS Seventy-three consecutive patients with acute high-grade AC joint separation were prospectively followed in 2 treatment groups (64.4% randomized, 35.6% patient-selected treatment): open reduction and cHP (cHP group) or arthroscopically assisted dDBS (dDBS group) performed within 14 days of injury. Patients were prospectively analyzed by clinical scores (Taft, Constant score [CS], numeric analog scale for pain) and AC-specific radiographs (AC distance, CC distance [CCD], relative CCD [rCCD; 100 / AC distance × CCD]) at points of examination (preoperative and 6, 12, and 24 months). The minimal clinically important differences (MCIDs) were assessed by the anchor-based method. RESULTS Twenty-seven of 35 patients (mean age ± SD: 37.7 ± 9.7 years) after cHP implantation and 29 of 38 patients (34.2 ± 9.7 years) after dDBS implantation were continuously followed until the 24-month follow-up. All patients showed significantly increased scores after surgery as compared with preoperative status (all P < .05). As compared with GI, GII had significantly better outcomes at 24 months (Taft: cHP = 9.4 ± 1.7 vs dDBS = 10.9 ± 1.1, P < .05, MCID = 2.9; CS: cHP = 90.2 ± 7.8 vs dDBS = 95.3 ± 4.4, P < .02, MCID = 16.6) and at 24 months for Rockwood IV/V (Taft: cHP = 9.4 ± 1.7 vs dDBS = 11.1 ± 0.8, P < .0005; CS: cHP = 90.1 ± 7.7 vs dDBS = 95.5 ± 3.1, P < .04). Clinically assessed horizontal instability persisted in 18.52% (GI) and 6.89% (GII; P = .24). The rCCD showed equal loss of reduction at 24 months (GII = 130.7% [control = 111%] vs GI = 141.8% [control = 115%], MCID = 11.1%). CONCLUSION This prospective study showed significantly superior outcomes in all clinical scores between GII and GI. The subanalysis of the high-grade injury type (Rockwood IV/V) revealed that these patients showed significant benefits from the dDBS procedure in the clinical assessments. The cHP procedure resulted in good to excellent clinical outcome data and displayed an alternative procedure for patients needing less restrictive rehabilitation protocols.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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 TomoFixTM 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.

Can young and active patients participate in sports after osteochondral autologous transfer combined with valgus high tibial osteotomy? Knee Surg Sports Traumatol Arthrosc 2016; 24:1594-600. [PMID: 25481807 DOI: 10.1007/s00167-014-3447-x] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2014] [Accepted: 11/14/2014] [Indexed: 01/18/2023]
Abstract
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.

Abstract
Background To evaluate return-to-activity (RtA) after anatomical reconstruction of acute high-grade acromioclavicular joint (ACJ) separation. Methods A total of 42 patients with anatomical reconstruction of acute high-grade ACJ-separation (Rockwood Type V) were surveyed to determine RtA at a mean 31 months follow-up (f-u). Sports disciplines, intensity, level of competition, participation in overhead and/or contact sports, as well as activity scales (DASH-Sport-Module, Tegner Activity Scale) were evaluated. Functional outcome evaluation included Constant score and QuickDASH. Results All patients (42/42) participated in sporting activities at f-u. Neither participation in overhead/contact sports, nor level of activity declined significantly (n.s.). 62 % (n = 26) of patients reported subjective sports specific ACJ integrity to be at least the same as prior to the trauma. Sporting intensity (hours/week: 7.3 h to 5.4 h, p = .004) and level of competition (p = .02) were reduced. If activity changed, in 50 % other reasons but clinical symptoms/impairment were named for modified behavior. QuickDASH (mean 6, range 0–54, SD 11) and DASH-Sport-Module (mean 6, range 0–56, SD 13) revealed only minor disabilities at f-u. Over time Constant score improved significant to an excellent score (mean 94, range 86–100, SD 4; p < .001). Functional outcome was not correlated with RtA (n.s.). Conclusion All patients participated in sporting activities after anatomical reconstruction of high-grade (Rockwood Type V) ACJ-separation. With a high functional outcome there was no significant change in activity level (Tegner) and participation in overhead and/or contact sports observed. There was no correlation between functional outcome and RtA. Limiting, there were alterations in time spent for sporting activities and level of competition observed. But in 50 % those were not related to ACJ symptoms/impairment. Unrelated to successful re-established integrity and function of the ACJ it should be considered that patients decided not return-to-activity but are very content with the procedure.

Abstract
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.

Abstract
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.

Abstract
PURPOSE The purpose of this study was to prospectively evaluate the clinical, radiographic, and sports-related outcome at 24 months after valgus-producing medial open-wedge high tibial osteotomy (owHTO) using a 2nd generation peek-carbon composite plate. METHODS Between 2010 and 2011, the 2nd generation PEEKPower HTO-Plate(®) was used for medial owHTO in 28 consecutive patients (19 men, 9 women; mean age ± SD: 45 ± 11 years; mean varus deviation ± SD: 4° ± 2°). All of the patients had an osteotomy gap height of ≤12 mm without bone grafting. Visual analog scale (VAS) for pain, WOMAC score, and Lysholm score were evaluated preoperatively and at 12 and 24 months postoperatively. Sports-related outcomes included the Tegner scale, and a self-designed questionnaire preoperatively and 24 months postoperatively. Fixation stability of the implant was evaluated radiographically in two planes by comparing the medial proximal tibial angle (MPTA) and tibial slope 2 days after medial owHTO (baseline measurements) and after implant removal (follow-up measurements). Complications were recorded during the whole study period. RESULTS Compared to preoperative conditions, VAS, WOMAC, and Lysholm scores improved significantly (p < 0.05) at the 12- and 24-month follow-up. No significant differences were found between the 12- and 24-month follow-up. After 24 months, the sports frequency increased significantly (p < 0.05). No significant differences between baseline and follow-up measurements for the MPTA and tibial slope were observed. Total complication rate was 4 %, with one patient developing non-union. CONCLUSION In the clinical practice, the 2nd generation PEEKPower HTO-Plate(®) is a safe and efficient implant for medial owHTO without bone grafting in patients with an osteotomy gap of ≤12 mm.

Abstract
Background Locking plate fixation of displaced fractures of the proximal humerus is still accompanied by a distinct complication rate, especially in case of osteoporotic bone, short-segment fracture length and comminution of the medial calcar. Secondary loss of reduction leading to varus deformity and screw cutout most frequently lead to surgical revision. The aim of the present study was to evaluate the clinical and radiological outcome of a recently developed polyaxial locking plate that allows for the additional placement of a helical blade device, aiming for support of the medial calcar. Methods In this prospective study, 17 patients with a mean age of 63.0 ± 16.0 years suffering from displaced fractures of the proximal humerus (Neer type two-, three- and four-part) were enrolled. All patients were surgically treated using a polyaxial locking plate with additional blade device (group PAB, n = 12) or without blade device (group PA, n = 5). Functional outcome was recorded using the Munich Shoulder Questionnaire allowing for qualitative self-assessment of the Shoulder Pain and Disability Index (SPADI), the Disability of the Arm, Shoulder and Hand (DASH score) and the Constant Score. Radiological outcome was assessed by analyzing standardized true anterior–posterior and outlet-view radiographs with respect to radiographic evidence of secondary varus displacement, cutout of screws and hardware failure. Results were compared to an age-, gender- and fracture type-matched collective treated by monoaxial locking plate fixation (group MA, n = 15). Results The mean follow-up was 12.4 ± 2.9 months after surgery. There were no statistical significant differences in clinical outcome in all three groups. Group MA and group PA revealed significant secondary varus displacement in comparison to group PAB at the final follow-up compared to postoperative analysis (p < 0.001). The distance between the blade and the articular surface showed no significant increase in group PAB at the final follow-up compared to postoperative analysis. Not-implant-related complications were seen in one and implant-related complications were seen in two patients in group PAB. Conclusions Polyaxial locking plate fixation with a blade device to restore medial cortical support reduces the risk of secondary varus displacement even in proximal humeral fractures of the elderly in comparison to monoaxial and polyaxial locking plate fixation without blade insertion.

Abstract
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.

Abstract
BACKGROUND This study evaluated the outcome of a third generation modular non-cemented reverse total shoulder arthroplasty (RTSA) in incongruent glenohumeral degeneration with severe rotator cuff deficiency. MATERIALS AND METHODS Thirty-eight consecutive RTSA with a mean age of 72 years (range 58-89 years) were prospectively enrolled. Mean follow-up was 24 months (range 21-29 months). Pain and standardized clinical functional scores were monitored. Radiographic and MRI findings have been scored and correlated to clinical outcome and complication rate. RESULTS Preoperative pain decreased significantly from VAS 8 to 2 at 24 months postop., as ROM improved significantly, by at least doubling preoperative values of elevation, abduction, and external rotation. Nevertheless, internal rotation languished. The preoperative median constant was 18 points and 70 points 24 months postop. (p < 0.001). Initial median DASH was 95 vs. 50 2 years after surgery (p < 0.001). Median prospective ASES was 23 (IQR 8-33) vs. 70 points (p < 0.001) at final follow-up. Each outcome measurement improved significantly at 6, 12, and 24 months follow-up. There was no significant correlation between pre-operative radiographic findings of osseous and/or soft-tissue degeneration and short-term clinical outcome and/or complication rate (13 %). At final follow-up, 54 % showed radiographic signs of inferior scapular notching. There was no revision and/or loosening observed. CONCLUSION RSTA with this modular system results in significant pain relief and improvement of functional clinical outcomes. However, longevity of the device is currently unknown.

Abstract
PURPOSE To evaluate whether isolated anatomical coracoclavicular (CC) ligament reconstruction with two suture-button devices provides equal horizontal acromioclavicular joint (ACJ) stability compared to additional ACJ suture tape cerclage. METHODS A servohydraulic testing machine was used to assess horizontal ACJ translation in 12 fresh-frozen human shoulders during 5,000 cycles of dynamic anteroposterior directed loading (70 N). Horizontal ACJ stability was assessed for native specimen (n = 6) and compared to specimen with dissected AC ligaments but intact CC ligaments (n = 6). After complete AC/CC dissection, an anatomical CC reconstruction was performed with two suture-button devices (n = 6) and compared to the additional ACJ suture tape cerclage (n = 6). RESULTS Native specimen showed an mean horizontal amplitude of 10.8 mm [standard deviation (SD) 3.29]. After 5,000 cycles of horizontal loading (70 N), mean amplitude increased by 1.5 mm (SD 0.75, p = 0.005). Specimen with dissected AC ligaments started at an mean amplitude of 14.1 mm (SD 4.11), which was increased by 0.9 mm (SD 0.56, n.s.) after loading. Initially, amplitude of specimen with anatomical CC reconstruction was 13.2 mm (SD 2.75), which increased by 2.9 mm (SD 1.45, p = 0.001) after loading. The specimen with additional AC cerclage initially showed an amplitude of 10.6 mm (SD 2.35). After loading, translation was increased by 3.0 mm (SD 0.97, p = 0.001). There was no failure of any surgical reconstruction in the tests. CONCLUSION The results of this study suggest that only combined AC and CC reconstruction can adequately re-establish physiological horizontal ACJ stability. Therefore, it is likely that a combined surgical procedure with double suture-button devices and AC suture tape cerclage can adequately re-establish horizontal AC joint stability in case of an acute injury (≥type Rockwood IV and may allow superior clinical outcomes for patients, especially if early functional rehabilitation is intended).

Abstract
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.

Abstract
UNLABELLED Patellofemoral malalignment can be caused by several factors including increased internal torsion of the femur. As a causative treatment method, supracondylar femoral derotation osteotomies have been proposed. For valgus- and varus-producing supracondylar femoral osteotomies, a biplanar osteotomy has been introduced in order to enhance primary fixation stability and osseous consolidation by increased bone-to-bone contact. In this article, a modification of this technique is described, which allows for a biplanar supracondylar femoral derotation osteotomy. LEVEL OF EVIDENCE V.

Abstract
BACKGROUND Deep osteochondral defects of the medial femoral condyle in young and active patients are a serious condition that might lead to early osteoarthritis of the knee joint. Concomitant varus malalignment most likely promotes this process because of overloading of the medial compartment. Osteochondral autologous transfer (OAT) combined with valgus high tibial osteotomy (HTO) might therefore be a comprehensive solution to preserve long-term knee function in these patients. PURPOSE To evaluate clinical long-term results and analyze survival rates (conversion to knee joint arthroplasty) after combined OAT and valgus HTO in young and active patients with symptomatic osteochondral defects of the medial femoral condyle and concomitant varus malalignment. STUDY DESIGN Case series; Level of evidence, 4. METHODS Between 1998 and 2008, combined OAT and valgus HTO was performed in 86 patients with deep osteochondral defects of the medial femoral condyle and concomitant varus malalignment >2°; 74 patients (86%) were available for follow-up evaluation. The mean age of patients was 38 years, and the mean follow-up time was 7.5 years. Knee function was assessed using the Lysholm score, and pain intensity was measured using the visual analog scale (VAS). The survival rates of this combined procedure were evaluated. Failure was defined as conversion to knee joint arthroplasty during the follow-up period. RESULTS Adjusted to follow-up time, the Lysholm score showed a mean increase of 33 points (95% CI, 27.1-39.4; P < .001) from 40 to 73, representing a significant improvement compared with preoperatively. The VAS score decreased by a mean of 4.8 points (95% CI, 4.1-5.5; P < .001) from 7.5 to 2.7, and 93% of the patients were satisfied with the results of the operative procedure. Mean survival rates were 95.2% ± 2.7% at 5 years, 93.2% ± 3.3% at 7 years, and 90.1% ± 4.4% at 8.5 years after surgery. CONCLUSION Combined OAT and valgus HTO is an option to successfully treat patients with deep osteochondral defects of the medial femoral condyle and concomitant varus malalignment. Significantly improved knee function, decreased pain intensity, and a high survivorship rate can be expected up to 8.5 years postoperatively.
