Pseudoparalysis and Acromiohumeral Interval Reversibility Are the Most Important Factors Affecting the Achievement of Patient-Acceptable Symptom State After Arthroscopic-Assisted Latissimus Dorsi Tendon Transfer.

PURPOSE: To determine the patient-acceptable symptom state (PASS) values for American Shoulder and Elbow Surgeons (ASES) score and the Constant-Murley (CM) score after arthroscopic-assisted latissimus dorsi tendon transfer (LDTT) and to identify potential factors affecting the achievement of PASS. METHODS: Fifty consecutive patients who underwent arthroscopic-assisted LDTT between 2015 and 2020 were retrospectively analyzed. In total, 42 patients met the inclusion criteria with minimum follow-up of 1 year postoperative. Patients were evaluated preoperatively and 1-year postoperatively with multiple clinical measurements including ASES, CM, score and PASS. The primary outcome was identified as patient satisfaction which assessed with achievement of a PASS. Potential factors affecting the patient satisfaction including age, sex, body mass index, previous surgery, presence of pseudoparalysis, critical shoulder angle, shoulder abduction moment index, acromiohumeral interval (AHI) reversibility, Hamada grade and fatty infiltration were evaluated for their association with PASS value by stepwise logistic regression analysis. RESULTS: A total of 42 patients were evaluated with mean follow-up 27.8 ± 8.21 months. The ASES and CM scores improved from preoperative means of 21.6 ± 6.5 and 25.2 ± 8.5 to 65.6 ± 20.7 points and 56.8 ± 16.5 points, respectively (P < .001). The PASS values for the ASES and CM scores were 62.4 and 52.5, respectively. The univariate analysis showed that older age (P = .021), presence of pseudoparalysis (P < .001), previous surgery (P = .016), lower preoperative AHI (P = .028), and lower AHI reversibility (P < .001) were all significantly associated with worse patient satisfaction. The multivariable logistic regression analysis showed that pseudoparalysis (P = .038) and AHI reversibility (P = .021) were independent prognostic factors affecting the achievement of a PASS after arthroscopic-assisted LDTT. The cutoff value for AHI reversibility to predict an achievement of PASS was found to be 4.0 mm. CONCLUSIONS: Arthroscopic-assisted LDTT led to satisfactory results in patients with massive rotator cuff tears. However, pseudoparalysis and AHI reversibility were the most important independent prognostic factors that consistently reduced and increased, respectively, the odds of achieving a PASS. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Treatment of knee osteochondritis dissecans with autologous tendon transplantation: Clinical and radiological results.

BACKGROUND: Defect treatment with tendon autograft in osteochondral lesions has been published in the literature with an experimental study in dogs. To demonstrate that it is possible to treat knee osteochondral lesions with the technique of autologous tendon transplantation. AIM: To evaluate the clinical and radiological results of patients with knee osteochondral lesions who were treated with autologous tendon transplantation. METHODS: Twenty patients (22 knees) with osteochondritis dissecans (OCD) lesions involving the knee were treated with autologous tendon transplantation between 2005-2018. All lesions were International Cartilage Repair Society grade IV. All patients were evaluated clinically at final follow-up with knee injury and osteoarthritis outcome score (KOOS); and radiologically with magnetic resonance observation and cartilage repair tissue (MOCART) and Kellgren-Lawrence (KL) classification. RESULTS: A total of 20 patients (22 knees) with a mean age of 25.5± 6.8 years were included. The average defect size was 4.2 ± 2.1 cm2, and the average defect depth was 0.9 ± 0.4 cm. Total KOOS score was preoperatively 29.4 ± 5.5 and was later found to be 81.5 ± 5.9 after an average of 68.7 ± 37.7 mo follow-up. The mean MOCART score was 56.2 ± 10.7. Preoperatively, all of the patients had KL grades of 0-1; during the follow-up period, 80% of the patients showed no radiological progress of osteoarthritis. Patients with less than 4 cm2 lesion had statistically significantly better overall KOOS than patients whose more than 4 cm2 lesion, particularly in sport and quality of life subscales. CONCLUSION: The autologous tendon transplantation is a single-step, safe, simple, cost-effective method for the treatment of knee OCD with satisfactory clinical and radiological outcomes, particularly in patients with less than 4 cm2 lesion.

Effectiveness and reliability of traditional open surgery in atypical localizations of osteoid osteoma.

OBJECTIVES: This study aims to evaluate traditional open surgery results of osteoid osteomas (OOs) in atypical localizations and explore whether open surgery can be a safe alternative in localizations where radiofrequency ablation (RFA) may not be suitable. PATIENTS AND METHODS: A total of 26 patients (20 males, 6 females; mean age 23.3±14.2 years; range, 4 to 65 years) having OO in atypical localizations between January 2008 and January 2017 were retrospectively evaluated. All patients underwent traditional open surgery under anesthesia. All patients were followed-up, and their clinical success and complications were evaluated. The pain intensity was assessed using the visual analog scale (VAS). RESULTS: The postoperative first year VAS score was 0.2±0.5 (range, 0-2) (p<0.005). None of the patients showed any complications. No recurrences were reported at the end of the first year. All patients were relieved from pain due to OO in atypical localizations. CONCLUSION: Although RFA has been accepted as the preferred treatment for OO, traditional open surgery may still be used for OO in atypical localizations yielding perfect clinical results with fewer complications. It is a safe alternative for localizations such as carpal bones, distal ulna, hand and foot where RFA complications can be seen more frequently. In these localizations, traditional open surgery can be recommended as the first treatment choice.

Editorial Commentary: What is the Difference That Makes the Differences? The Practical Rationality of the All-Suture Anchor.

Suture anchor technologies are constantly being innovated in the quest for improved stability, biological integration and clinical outcomes. However, the decision about the choice of suture-anchor materials remain elusive. There are some factors, including reliability, effectiveness, simplicity, familiarity, and cost, that affect a surgeon's preference. The relative weights placed on different factors by different surgeons play decisive roles in individual choice. But decisions and choices are not arbitrary or merely subjective. Alternative options can be warranted or contested by rational argumentation. At the end, there may be losses and gains in the change of 1 suture anchor for another, but science does progress.

Comparison of the clinical results of isolated Bankart and SLAP 5 lesions after arthroscopic repair.

OBJECTIVES: This study aims to compare the clinical results of patients with traumatic isolated Bankart lesions and type V superior labrum anterior to posterior (SLAP) lesions after arthroscopic repair. PATIENTS AND METHODS: Patients who underwent arthroscopic repair for traumatic anterior glenohumeral instability were evaluated retrospectively between December 2014 and January 2019. Fifty-one patients (49 males, 2 females; mean age 25 years; range, 18 to 36 years) without bone defects affecting >20% of the glenoid fossa, off-track engaging Hills-Sachs lesions, multidirectional instability, or ligamentous laxity were included in the study. Group 1 had 31 patients with isolated Bankart lesions and group 2 had 20 patients with type V SLAP lesions. There were only two female patients in group 1 and all patients were male in group 2. The mean age was 25 years (range, 18 to 36 years) in group 1 and 25 years (range, 19 to 35 years) in group 2. Rowe, Constant, and Western Ontario Shoulder Instability (WOSI) scoring systems were used to evaluate the clinical outcomes of the patients preoperatively and at the last follow-up. RESULTS: The mean follow-up time was 32 months (range, 12 to 48 months) in group 1 and 28.5 months (range, 12 to 42 months) in group 2. There were no statistically significant differences between the two groups in terms of the number of shoulder dislocations before the surgery, mean age at the time of surgery, and the mean time from the first dislocation to surgical treatment. When the Rowe, Constant, and WOSI scores were evaluated preoperatively and at the last follow-up, there were statistically significant changes within, but not between, the two groups. CONCLUSION: In type V SLAP lesions, the affected and repaired labrum surface area is larger than isolated Bankart lesions. However, as a result of appropriate surgical treatment, the affected surface area does not have a negative effect on clinical outcomes, and similar clinical results can be obtained in patients with type V SLAP lesions compared to patients with isolated Bankart lesions.

Extensor mechanism reconstruction with peroneus longus tendon autograft for neglected patellar fracture, report of 2 cases.

Extensor mechanism deficiency in the knee may occur due to neglected patellar and quadriceps tendons rupture or may be caused by chronic fractures of the patella. Older patients can tolerate nonunion with impaired function including extension limitation or persistent muscle weakness. In young patients, performing rigid internal fixation with reoperation should be considered when a nonunion occurs. However, delayed and neglected nonunion in patella fractures require performing different surgical procedures. We report two cases, operated for a patella fracture, in whom nonunion occurred and accompanied by patellar migration and retraction of quadriceps tendon because of a fixation failure. We reconstructed the extensor mechanism with peroneus longus tendon autograft and, owing to this method, we achieved excellent functional results during a 2-year follow-up period.

Arthroscopic glenoid labral lesion repair using all-suture anchor for traumatic anterior shoulder instability: short-term results.

BACKGROUND: This study presents the preliminary clinical results of arthroscopic glenoid labral lesion repair using all-suture anchors in the treatment of recurrent traumatic anterior shoulder instability. METHODS: Seventy patients who underwent arthroscopic shoulder stabilization for traumatic anterior shoulder instability were evaluated in this single center-based retrospective study. Patients with a glenoid defect greater than 20%, off-track engaging Hills-Sachs lesion, multidirectional instability, and generalized ligamentous laxity were excluded. The 62 included patients treated with arthroscopic glenoid labral lesion repair using all-suture anchors were evaluated. The Rowe and Constant scores were used to assess the results. RESULTS: We evaluated 62 patients with a mean age of 26.7 ± 12 years. The mean Rowe and Constant scores were 35 ± 7.2 and 65 ± 6.3, respectively, preoperatively and increased to 93.6 ± 5.3 and 92 ± 4.3, respectively, postoperatively at the mean follow-up of 28.8 months (range, 24-48 months) (P < .001). The redislocation rate was 8.1%. Of the patients, 91.9% had good to excellent clinical scores. Younger age and contact sports were associated with a higher risk of recurrent dislocation (P = .012 and P = .041, respectively). The postoperative functional results were not significantly correlated with the findings concerning the number of dislocations, time until surgery, degree of anterior translation, and number of anchors. CONCLUSION: The use of all-suture anchors for arthroscopic glenoid labral lesion repair for the treatment of recurrent traumatic anterior shoulder instability yields satisfactory clinical results and is a safe and effective option.

Extracranial location of the osteoma: Patella, case report and literature review.

Osteoma is a benign tumor. Extracranial cases are very rare. Twelve cases have been reported by 10 different authors in the literature. To our knowledge, osteoma was never reported in the patella. In this article, we report a 61-year-old male patient who presented with a painless mass in the patella of his right knee, which appeared almost four years before and showed a progressive enlargement in the past six months. Range of motion (ROM) of the joint was limited. Marginal excision was performed under regional anesthesia and the histopathological evaluation of the lesion confirmed the diagnosis of osteoma. There were no postoperative complications and the ROM of the joint returned to normal. Patient was followed-up for 24 months without any recurrence. This case of peripheral osteoma identified in the patella is an example of an atypical presentation. Patella tumors may affect the extensor mechanism. Therefore, detailed examination should be performed and differential diagnosis should be established carefully.

Arthroscopic-Assisted Latissimus Dorsi Tendon Transfer for Massive, Irreparable Rotator Cuff Tears: Technique and Short-Term Follow-Up of Patients With Pseudoparalysis.

PURPOSE: To describe a modified technique for arthroscopic-assisted transfer of the latissimus dorsi tendon in a selected group of patients with irreparable rotator cuff tears and pseudoparalysis and to evaluate its short-term results. METHODS: Fifteen patients with irreparable rotator cuff tears and pseudoparalysis treated by arthroscopic-assisted latissimus dorsi tendon transfer were included. The mean patient age was 61.53 ± 6.24 years (range, 52-71 years). Patients were assessed with physical examination, University of California Los Angeles (UCLA) Score and Constant-Murley score, as well as visual analog scale score at a mean follow-up of 26.4 ± 2.58 months (range, 24-31 months). RESULTS: At final follow-up, mean UCLA score increased to 27.47 ± 6.31 compared with the preoperative UCLA score of 6.53 ± 2.1 (P < .001). Constant-Murley score was 21 ± 7.41 and 59.73 ± 13.62 (P < .001), visual analog scale pain score was 7.47 ± 1.06 and 2.47 ± 0.91 (P < .001), active forward flexion was 58° ± 21.11° and 130° ± 30.05° (P < .001), active abduction was 51° ± 21.64° and 129.67° ± 25.45° (P < .001), and active external rotation was 13.33° ± 21.68° and 32° ± 18.03° (P < .001) preoperatively and postoperatively, respectively. Mean acromiohumeral distance was 3.13 ± 1.40 mm preoperatively, whereas it was 5.67 ± 1.67 mm postoperatively (P < .001). No significant complications requiring a revision surgery was observed during the final follow-up. CONCLUSIONS: The modified technique of arthroscopic-assisted transfer of the latissimus dorsi tendon is a feasible, minimally invasive option for the surgical treatment of irreparable rotator cuff tears in a subset of patients with pseudoparalysis. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

A study to develop clinical decision rules for the use of radiography in wrist trauma: Karadeniz wrist rules.

INTRODUCTION: The aim of this study was to evaluate patients presenting to the emergency department (ED) with wrist trauma using physical examination findings and functional tests and to identify findings with high sensitivity and specificity among the parameters assessed in patients with fracture in the wrist. The ultimate objective was thus to establish a reliable and widely usable clinical decision rule for determining the necessity of radiography in wrist trauma. METHODS: This prospective, multicenter study was performed in 8 hospitals. The relation between radiologically determined fracture and clinical findings consisting of physical examination findings and functional tests was assessed in terms of whether or not these were markers of radiography requirement, with the aim of identifying predictive values for fracture. RESULTS: A total of 603 eligible trauma patients presented to the participating EDs during the study period. Fracture was identified in 24.5% of patients (n = 148). The 4-way combination with the highest sensitivity was identified as axial compression and the positive distal radioulnar drawer test, and pain with radial deviation and dorsal flexion. Sensitivity at distal ulna palpation was added as a fifth parameter, and sensitivity and negative predictive value thus increased to 100%. CONCLUSION: With their 100% sensitivity and 100% negative predictive values, the Karadeniz wrist rules may represent a clinical decision rule that can be used in practice in EDs. If all 5 findings are negative, there is no indication for wrist radiography.

Transmission and scanning electron microscopy confirm that bone microstructure is similar in osteopenic and osteoporotic patients.

OBJECTIVES: The objective was to confirm the finding of "Bone microstructure is similar in osteopenic and osteoporotic patients with femoral neck fracture." obtained in previous "light microscopy study", which was new and important data. PATIENTS AND METHODS: Fourteen patients (5 males, 9 females) who were admitted with proximal femoral fracture following low energy trauma (patients who participated in the light microscopy study) were included. The patients were divided into two groups based on the bone mineral density (BMD) measurement, including osteopenic group (n=7, mean age 69 years; range 63 to 74 years) and osteoporotic group (n=7, mean age 74.1 years; range 67 to 78 years). Cortical and trabecular bone samples were taken from the patients who underwent endoprosthesis during partial hip arthroplasty and these samples were analyzed using transmission electron microscopy and scanning electron microscopy evaluations which are more sophisticated higher resolution techniques. RESULTS: The mean cortical bone thickness was 3622.14 mm in osteopenic group and 2323.14 mm in osteoporotic group (p<0.005). Transmission electron microscopy and scanning electron microscopy evaluations revealed similar findings for both groups. CONCLUSION: Although a significant difference in cortical thickness was found between the groups, transmission and scanning electron microscopy confirmed that bone microstructure shared similar characteristics in osteopenic and osteoporotic patients with low-energy femoral neck fracture, as it was in previous light microscopy study.

[A comparison of the measurements with biochemical markers of bone turnover and bone mineral density in the assessment of the efficiency of osteoporosis treatment]. / Osteporoz tedavisinin etkinliginin degerlendirilmesinde kemik döngüsü biyokimyasal belirteçleri ve kemik mineral yogunlugu ölçümlerinin karsilastirilmasi

OBJECTIVES: This study aims to compare the measurements using biochemical markers of bone turnover and bone mineral density (BMD) in the assessment of the efficiency of osteoporosis treatment. PATIENTS AND METHODS: Between March 2006 and December 2008, 166 patients with osteoporosis in our clinic were included. Patients who were out of contact due to death or other reasons during follow-up were excluded. We compared the measurements of urinary biochemical markers of bone turnover using cross-linked N-telopeptide (Ntx) values and BMD in 60 patients (49 females, 11 males; mean age: 65.7 years; range: 42 to 87 years) with osteoporosis who were treatment-naive and completed study. RESULTS: Twenty-nine (48.3%) of the patients received surgical treatment, while 31 (51.7%) received conservative therapy. Urine NTx values of the patients decreased 38.82% at three months; 51.99% at six months and 66.41% at 12 months. Lumbar vertebra BMD increased by 20.7% and femur neck BMD increased by 11.9% at the end of the first year. CONCLUSION: Urine NTx values respond to osteoporosis treatment faster than BMD measurements; thereby it may be suitable to use this parameter for the monitorization of the treatment efficiency.

[Is bone microstructure different between osteopenic and osteoporotic patients with femoral neck fracture?]. / Femur boyun kirigi olan osteopenik ve osteoporotik hastalarda kemik mikromimarisi farkli midir?

OBJECTIVES: This study aims to investigate whether bone microstructure is different between osteopenic and osteoporotic patients with femoral neck fracture. PATIENTS AND METHODS: Fourteen patients (5 males, 9 females) with proximal femoral fracture following low energy trauma were included in the study. Patients with secondary osteoporosis and who received antiosteoporotic treatment prior to trauma were excluded. The patients were divided into two groups based on the bone mineral density measurement, including osteopenic group (n=7, mean age 69 years; range 63-74 years) and osteoporotic group (n=7, mean age 74.1 years; range 67-78 years). Cortical bone specimens for biopsy obtained from the patients who underwent endoprosthesis during partial hip arthroplasty and were evaluated using light microscope. RESULTS: Mean cortical bone thickness was 3622.14 µM in osteopenic group, and 2323.14 µM in osteoporotic group (p<0.005). However, light microscope revealed similar characteristics for both groups. CONCLUSION: Although a significant difference was found between the groups in terms of cortical thickness, bone microstructure showed similar characteristics in osteopenic and osteoporotic patients with low energy femoral neck fracture.
