Shoulder-Pacemaker Treatment Concept for Posterior Positional Functional Shoulder Instability: A Prospective Clinical Trial

Background: Pathological muscle activation patterns of the external rotators and periscapular muscles can result in posterior positional functional shoulder instability (PP-FSI). In several patients, physical therapy and surgical treatment are not successful. Purpose: The shoulder-pacemaker treatment concept was evaluated prospectively in patients with PP-FSI and previously failed conventional therapy attempt. Study Design: Case series; Level of evidence, 4. Methods: A negative selection of 24 consecutive cases of noncontrollable PP-FSI in 16 patients with previously failed conventional therapy were included in this prospective study. The shoulder-pacemaker treatment consisted of an electrical muscle stimulation–based therapy protocol with 9 to 18 one-hour treatment sessions. Two patients were excluded because of nonadherence to the training schedule, leaving a final study cohort of 21 cases in 14 patients. Follow-up included assessment of clinical function, impairment during daily activities and sports, satisfaction, Western Ontario Shoulder Instability Index (WOSI), Rowe score, and Subjective Shoulder Value at 0 weeks, 2 weeks, 4 weeks, 3 months, 6 months, 12 months, and 24 months after intervention. Results: WOSI, Subjective Shoulder Value, and Rowe score showed a highly significant improvement at all time points of follow-up ( P < .001). Young age ( P = .005), low weight ( P = .019), shoulder activity level ( P = .003), unilateral affliction ( P = .046), and higher baseline WOSI score ( P = .04) were associated with a better treatment effect. Cases with increased glenoid retroversion, posterior scapulohumeral decentering, and dysplastic bony glenoid shape showed a trend toward shorter treatment effect duration. No complications during the intervention or follow-up period were observed. Conclusion: The shoulder-pacemaker therapy concept is an effective treatment with rapid improvement and sustained outcome over the course of 2 years in patients with noncontrollable PP-FSI with previously failed conventional treatment. Young and more athletic patients with lower weight and unilateral pathology respond best to the treatment.

Background: The collagen meniscal implant (CMI) is a biologic scaffold aimed at replacing partial meniscal defects. The long-term results of lateral meniscal replacement have never been investigated. Purpose: To document the clinical outcomes and failures of lateral CMI implantation for partial lateral meniscal defect at a minimum 10-year follow-up. Study Design: Case series; Level of evidence, 4, Methods: This study included 24 consecutive patients who underwent lateral CMI implantation for partial lateral meniscal defects between April 2006 and September 2009 and who were part of a previous study with a 2-year follow-up. Outcome measures at the latest follow-up included the Lysholm score, Knee injury and Osteoarthritis Outcome Score, visual analog scale (VAS) for pain, Tegner activity level, and EuroQol 5-Dimensions score. Data regarding complications and failures were collected, and patients were asked about their satisfaction with the procedure. Results: Included in the final analysis were 19 patients (16 male, 3 female) with a mean age at surgery of 37.1 ± 12.6 years and a mean follow-up of 12.4 ± 1.5 years (range, 10-14 years). Five failures (26%) were reported: 1 CMI removal because of implant breakage and 4 joint replacements (2 unicompartmental knee arthroplasties and 2 total knee arthroplasties). The implant survival rate was 96% at 2 years, 85% at 5 years, 85% at 10 years, 77% at 12 years, and 64% at 14 years. Lysholm scores at the final follow-up were rated as “excellent” in 36% (5 of 14 nonfailures), “good” in 43% (6 of 14), and “fair” in 21% (3 of 14). The VAS score was 3.1 ± 3.1, with only 16% (3 of 19 patients) reporting that they were pain-free; the median Tegner score was 3 (interquartile range, 2-5). All clinical scores decreased from the 2-year follow-up; however, with the exception of the Tegner score, they remained significantly higher compared with the preoperative status. Overall, 79% of patients were willing to undergo the same procedure. Conclusion: Lateral CMI implantation for partial lateral meniscal defects provided good long-term results, with a 10-year survival rate of 85% and a 14-year survival rate of 64%. At the final follow-up, 58% of the patients had “good” or “excellent” Lysholm scores. However, there was a general decrease in outcome scores between the short- and the long-term follow-up.

Background: Overground Robot-Assisted Gait Training (o-RAGT) appears to be a promising stroke rehabilitation in terms of clinical outcomes. The literature on surface ElectroMyoGraphy (sEMG) assessment in o-RAGT is limited. This paper aimed to assess muscle activation patterns with sEMG in subjects subacute post stroke after training with o-RAGT and conventional therapy. Methods: An observational preliminary study was carried out with subjects subacute post stroke who received 15 sessions of o-RAGT (5 sessions/week; 60 min) in combination with conventional therapy. The subjects were assessed with both clinical and instrumental evaluations. Gait kinematics and sEMG data were acquired before (T1) and after (T2) the period of treatment (during ecological gait), and during the first session of o-RAGT (o-RAGT1). An eight-channel wireless sEMG device acquired in sEMG signals. Significant differences in sEMG outcomes were found in the BS of TA between T1 and T2. There were no other significant correlations between the sEMG outcomes and the clinical results between T1 and T2. Conclusions: There were significant functional gains in gait after complex intensive clinical rehabilitation with o-RAGT and conventional therapy. In addition, there was a significant increase in bilateral symmetry of the Tibialis Anterior muscles. At this stage of the signals from the tibialis anterior (TA), gastrocnemius medialis (GM), rectus femoris (RF), and biceps femoris caput longus (BF) muscles of each lower extremity. sEMG data processing extracted the Bilateral Symmetry (BS), the Co-Contraction (CC), and the Root Mean Square (RMS) coefficients. Results: Eight of 22 subjects in the subacute stage post stroke agreed to participate in this sEMG study. This subsample demonstrated a significant improvement in the motricity index of the affected lower limb and functional ambulation. The heterogeneity of the subjects’ characteristics and the small number of subjects was associated with high variability research, functional gait recovery was associated with minimal change in muscle activation patterns.

Purpose To evaluate the long-term outcome of a modified inferior capsular shift procedure in patients with atraumatic anterior-inferior shoulder instability by analyzing a consecutive series of patients who had undergone a modified inferior capsular shift for this specific type of shoulder instability. Study Design Case series; Level of evidence, 4. Methods Between 1992 and 1997, 38 shoulders of 35 patients with atraumatic anterior-inferior shoulder instability that were unresponsive to nonoperative management were operated on using a modified capsular shift procedure with longitudinal incision of the capsule medially and a bony fixation of the inferior flap to the glenoid and labrum in the 1 o'clock to 3 o'clock position. The patient study group consisted of 9 men and 26 women with a mean age of 25.4 years (range, 15-55 years) at the time of surgery. The mean follow-up was 7.4 years (range, 4.0-11.4 years); 1 patient was lost to follow-up directly after surgery. The study group was evaluated according to the Rowe score. Results After 7.4 years, 2 patients experienced a single redislocation or resubluxation, 1 patient had recurrent dislocations, and 1 patient had a positive apprehension sign, which is an overall redislocation rate of 10.5%. The average Rowe score increased to 90.6 (SD = 19.7) points from 36.2 (SD = 13.5) points before surgery. Seventy-two percent of the patients participating in sports returned to their preoperative level of competition. Conclusions Results in this series demonstrate the efficacy and durability of a modified capsular shift procedure for the treatment of atraumatic anterior-inferior shoulder instability.

Abstract PurposeFocal articular cartilage injuries are common and may lead to progression of osteoarthritis. The complications associated with traditional treatment strategies have influenced the development of new biotechnologies, such as the ProChondrix® osteochondral allograft. Clinical evidence on the outcomes associated with ProChondrix® osteochondral allografts are limited. Thus, the primary purpose of this study was to evaluate the clinical outcomes following treatment of an isolated cartilage defect with a ProChondrix® osteochondral allograft implant.MethodsRetrospective analysis of patients who underwent a cartilage restoration procedure using ProChondrix® osteochondral allograft has been performed. Patients completed patient-reported outcome surveys which included the Knee injury and Osteoarthritis Outcome Score (KOOS), consisting of the 5 subscales of Pain, Symptoms, Activities of Daily Living, Sports and Recreation, and Quality of Life, the Marx Activity Scale, and the visual analog pain scale.ResultsSix patients underwent a cartilage restoration procedure using ProChondrix® between January 2016 and December 2019. Three males and three females were included with a median age of 33.5 years (range 18–48 years). The median follow-up duration was 15 months (range 9–24 months). There were 4 patellar grafts, 1 medial femoral condyle graft, and 1 lateral femoral condyle graft, with a median defect size of 18.5mm (range 13-20mm). At the most recent clinical follow-up, all six patients were pain free and all patients had returned to pre-op activity level.ConclusionTo our knowledge, this is the first study to report the clinical outcome, activity level, and patient orientated outcomes in a case series of patients following treatment of an isolated cartilage defect with a ProChondrix® osteochondral allograft implant. Our study demonstrates promising short-term results in patient reported clinical outcome scores.

Background: An unsalvageable osteochondritis dissecans (OCD) fragment has been defined as one that cannot be saved. Unsalvageable OCD lesions have been treated with various techniques, including fragment excision, microfracture, osteochondral autograft transfer, fresh osteochondral allograft transplantation, and autologous chondrocyte implantation (ACI). Hypothesis: Patients who underwent ACI as treatment for unsalvageable OCD more than 10 years ago would maintain satisfactory patient-oriented outcome measures and have a low need for additional open surgery, especially arthroplasty. Study Design: Case series; Level of evidence, 4. Methods: All Swedish and Norwegian patients (59 patients with 67 OCD lesions) who underwent ACI for OCD under the direction of the senior author between 1990 and 2005 were identified through manual chart review. Features of the patient, OCD lesion, and surgery were extracted from the medical record and intraoperative photographs. Patients were sent questionnaires to assess the Knee injury and Osteoarthritis Outcome Score, Tegner-Wallgren activity score, and Lysholm score. In addition, patients were asked whether they had to undergo further surgery, including knee replacement, of the knee that underwent ACI. They were asked whether they would have the surgery again if in the same situation. Results: A total of 55 patients (93%) with 61 OCD lesions (91%) responded. The median follow-up duration was 19 years (range, 10-26 years) and the median age at follow-up was 43 years (range, 28-69 years). Subsequent arthroscopy was performed in the majority of cases, although many of these were scheduled “second looks” as part of a study. With respect to other subsequent surgery, 12 knees (20%) underwent any additional open surgery, but only 2 knees (3%) underwent arthroplasty. Eight knees (13%) underwent revision ACI. Most patients reached their preinjury activity level (62%) and would undergo ACI again if in the same situation (85%). If failure is defined as revision of the graft or conversion to arthroplasty, then survivorship after ACI for OCD in the current study would be 87% at 10 years, 85% at 15 years, and 82% at 20 years. Conclusion: ACI for OCD provides a durable treatment option. At a median follow-up of 19 years, there was a very low (~3%) conversion to total knee arthroplasty.

Background: Arthroscopic microfracture for osteochondral lesions of the talus (OLT) has shown good functional outcomes. However, some studies have reported that functional outcomes deteriorate over time after surgery. Purpose: To use various functional scoring systems to evaluate functional outcomes in a large sample of patients with OLT treated by arthroscopic microfracture. Study Design: Case series; Level of evidence, 4. Methods: The study cohort consisted of 165 ankles (156 patients) that underwent arthroscopic microfracture for small to mid-sized OLT. The mean lesion size was 73 mm2 (range, 17-146 mm2), and the mean follow-up period was 6.7 years (range, 2.0-13.6 years). The Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale, visual analog scale (VAS) for pain, and 36-Item Short Form Health Survey (SF-36) were used to compare the functional outcomes between the preoperative and final follow-up assessments. Results: The mean FAOS significantly improved in regard to all subscores ( P < .001). The AOFAS ankle-hindfoot scale showed an improvement from 71.0 points (range, 47.0-84.0) preoperatively to 89.5 points (range, 63.0-100) at the final follow-up ( P < .001). The VAS score showed an improvement from 6.2 points (range, 4.0-9.0) preoperatively to 1.7 points (range, 0-6.0) at the final follow-up ( P < .001). The mean SF-36 score improved from 62.4 points (range, 27.4-76.6) preoperatively to 76.2 points (range, 42.1-98.0) at the final follow-up ( P < .001). Among 165 ankles, 22 ankles (13.3%) underwent repeat arthroscopic surgery for evaluation of repaired cartilage status. Conclusion: Arthroscopic microfracture showed good functional outcomes and improved quality of life with maintenance of satisfactory outcomes at a mean follow-up of 6.7 years. Therefore, arthroscopic microfracture seems to be reliable as a first-line treatment for OLT at an intermediate-term follow-up.

Objectives: There is only sparse data on clinical results and complications of the third-generation Gamma nailing system (Gamma3, Stryker). Therefore, we started a large multi-centre case series in 2008. The aim of this paper is to present the study design and early results of a single arm of a prospective, consecutive, monitored, post-market follow-up evaluation of Gamma3 nails. Methods: From September 2009 to January 2012, 154 consecutive patients with an average age of 80 ± 1.43 years (50-99 years) and a trochanteric femoral fracture were included in the local arm of the trial. All patients that fulfilled the inclusion criteria were treated with a Gamma3 nail. Preoperative variables included age, gender, fracture classification, walking ability (Merle d’Aubigné score), daily activity level (retrospective Zuckerman score), ASA rating of operative risk, waiting time for operation, use of walker or crutches and body mass index (BMI). Skin-to-skin time, fluoroscopy time, blood loss, intraoperative complications and device information were recorded for each patient. Follow-up postoperative assessment was undertaken at 4, 12 and 24 months. Hip range of motion, pain around the hip and the tight, walking ability (Merle d’Aubigné score, Sahlgrenska mobility score) and management of daily life (Zuckerman score) were used to evaluate the outcome. Results: The descriptive data of age, gender, BMI, ASA classification, fracture type and skin-to-skin time is similar to other studies. Median fluoroscopy time was 62 seconds (range: 4-225 seconds) and significantly shorter in closed reductions. No intraoperative implant-related complication was recorded. A cut-out of the leg-screw during assessment period occurred in 2.6% patients (n = 4). At the 12-month assessment two (1.8%) non-unions were identified and two patients (1.8%) had broken the femoral shaft below the 180 mm nail after a fall. Analysis of the scores showed significantly declined mobility and activity in daily life four months after operation which increased significantly from four to 12 months and increased slightly between 12 and 24 months after fracture. Conclusion: A low implant-associated complication rate was achieved in geriatric patients with trochanteric femoral fractures using the Gamma3 nail. A better outcome concerning mobility, activity in daily life and complications compared to the Gamma2 nail could not be found in comparison to historic data.

Category: Ankle, Ankle Arthritis, Arthroscopy Introduction/Purpose: The role of ankle arthroscopy in managing the consequences of ankle fractures is yet to be fully estab- lished. This study aims to assess this procedure in terms of the accuracy of preoperative diagnosis, re-operation rate and patient- reported outcomes. Methods: We compared two homogeneous groups of 16 patients (32 in total, average age 40.6 years) operated for a fracture of the distal tibia and/or fibula treated with ORIF. For all fractures the AO classification was used. The baseline was 6 months after surgery. Inclusion criteria were: patients aged between 19 and 50 a pre-trauma Tegner score >3, FAOS score <75 at the baseline, R.O.M. <20° vs contralateral; we included patients with well-aligned osteosynthesis and with radiographic union. Patients with open fractures, with osteochondral lesions and with previous were excluded. In the first group we planned an arthroscopy of the ankle from 6 to 12 months after trauma, in the second group, we continued with conservative rehabilitation treatment. All patients were then re-evaluated at 3,6 and 12 months with questionnaires (Tegner activity level, and FAOS). The mean follow-up was 18.2 months. For all data statistical analysis was performed. Results: The results of our case-series showed excellent patient satisfaction (12/14) with a FAOS Score and an improved R.O.M. statistically significant (p <.001) in patients treated with ankle arthroscopy. Eighty percent was able to return to previous activity. The average time until return to sport was 5.3 ± 2.4 months. Seventy percent of the athletes still had occasional pain with sport. Conclusion: The literature on arthroscopic treatment after fracture is still poor but results obtained, even with a limited number of cases, and with a short follow-up, are positive, especially in those patients where the functional demand is highest.

Background: High-grade partial-thickness rotator cuff tears (hPTRCTs) are frequently encountered in the shoulder. However, little information is available on the prevalence or timing of tear progression. Purpose/Hypothesis: The purpose was to prospectively evaluate the structural progression of hPTRCTs with a minimum follow-up of 1 year using magnetic resonance imaging (MRI). The hypothesis was that a substantial portion of hPTRCT patients would experience tear progression or evolution to a full-thickness rotator cuff tear. Study Design: Case series; Level of evidence, 4. Methods: Between May 2010 and December 2015, 362 patients were diagnosed with hPTRCT (tear involvement >50% of the mediolateral length of the footprint) of the supraspinatus and were treated nonoperatively. Among these patients, 81 underwent follow-up MRI at least 1 year after initial presentation, and these patients were included in the final analysis. Initial and follow-up MRIs were used to determine whether tears had improved, had not changed, or had progressed. A change in tear involvement of >20% was defined as a significant change. Patients were categorized as follows: (1) a decrease in tear involvement of >20% (improved), (2) an increase or decrease of ≤20% (no change), or (3) an increase in tear involvement of >20% (progressed). Demographic data and morphologic data were analyzed to identify variables related to tear progression. Among them, severity of tendinosis was graded using MRIs: grade 1 (mild tendinosis), mild focal increase in tendon signal; grade 2 (moderate tendinosis), moderate focal increase in tendon signal; and grade 3 (marked tendinosis), marked generalized increase in tendon signal. Results: At initial diagnosis, 23 were articular-side (28%) and 58 were bursal-side (72%) hPTRCTs. The study cohort was composed of 51 women and 30 men, and the mean patient age was 62.3 years (range, 41-77 years). Follow-up MRI was performed at a mean 19.9 ± 10.9 months (range, 12-52 months). A significant change in tear involvement was observed at follow-up. In 13 patients (16%, 2 articular-side and 11 bursal-side tears), tears were classified as progressed (the progressed group); in 48 patients (59%), tears exhibited no change (the unchanged group); and in 20 patients (25%, 9 articular-side and 11 bursal-side tears), tears were improved (the improved group). Univariate analysis showed initial tendinosis grade was significantly different in the 3 groups (grade 1, 2, and 3: 5, 4, and 4 in progressed; 36, 11, and 1 in unchanged; 10, 8, and 2 in improved group, respectively, P = .007). Conclusion: Although progression of hPTRCT in the long term is uncertain, after 1-year follow-up with MRI, tears progressed in 16% of the tears in this study. Furthermore, some tears were healed or reduced in size, which indicates that decisions to undertake surgical repair at time of presentation may be excessive.

Introduction: The number of total knee replacements performed (TKR) is increasing and so are patient expectations and functional demands. The mean age at which orthopedic surgeons may indicate TKR is decreasing, and therefore return to sport (RTS) after TKR is often an important expectation for patients. The aim of this study was to analyze the mid-term RTS, recreational activities, satisfaction level, and forgotten joint level after TKR. Methods: Between January 2015 and December 2016, 536 TKR (same implant design, same technique) were performed in our center. The mean age at survey was 69 years with a mean follow-up of 43 months. All patients who did not have a follow-up in the last 6 months were called. Finally, 443 TKR were analyzed. RTS was assessed using the University of California Los Angeles Scale (UCLA), forgotten joint score (FJS), and Satisfaction Score. Results: In this study, 85% of patients had RTS after TKR with a mean UCLA score increasing from 4.48 to 5.92 and a high satisfaction rate. Satisfaction with activity level was 93% (satisfied and very satisfied patients). The RTS is more important for people with a higher preoperative UCLA score and a lower American Society of Anesthesiologist score (ASA). Each point increase in ASA score is associated with reduced probability to RTS by 52%. Discussion: RTS and recreational activity were likely after TKR with a high satisfaction score. Preoperative condition and activity are the two most significant predictive factors for RTS. Level of evidence: Retrospective case series, level IV.
