Use and Effectiveness of Physical Therapy After Hip Arthroscopy for Femoroacetabular Impingement.

BACKGROUND: Limited literature exists regarding how postoperative physical therapy (PT) may affect outcomes in patients with femoroacetabular impingement syndrome (FAIS) undergoing hip arthroscopy. Additionally, it is unknown how PT measures relate to traditional orthopaedic patient-reported outcomes (PROs). PURPOSE: To evaluate how the duration of PT may correlate with outcomes in patients with FAIS using both the Lower Extremity Functional Scale (LEFS) and standard orthopaedic PRO measures. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients from a single institution who underwent primary hip arthroscopy for FAIS between 2013 and 2016 were identified. Patients with a minimum 2-year follow-up and fully documented PT notes were included and stratified into 3 cohorts based on timing of PT discharge: 0 to 3 months, 3 to 6 months, and 6 to 12 months. Predictive regression models were developed to analyze the rate of improvement (ROI) in LEFS score as it relates to (1) postoperative day (POD) and (2) postoperative PT session number. Two-year PROs were collected, correlated with LEFS scores, and compared among cohorts. RESULTS: A total of 95 patients were included (mean ± SD age, 34.6 ± 11.7 years; range, 14-55 years). Mean LEFS scores increased significantly from the initial score at 6 weeks, 3 months, and the time of PT discharge (P < .01 for all). The predicted ROI in LEFS score was 3.39% per PT session for sessions 0 to 13, 1.43% for sessions 14 to 27, and 0.37% for sessions 28 to 40. Patients who underwent 3 to 6 months of PT had significantly better Hip Outcome Score (HOS) relative to the 0- to 3-month cohort and significantly better visual analog scale (VAS) scores for satisfaction relative to the 6- to 12-month cohort. The predicted ROI in LEFS score was 0.96% per day from POD 0 to 45, 0.22% from POD 46 to 139, and 0.03% after POD 139. Moderate correlations were seen between LEFS score at the time of discharge and all 2-year PROs as follows: HOS Activities of Daily Living subscale (r = 0.488), HOS Sports-Specific subscale (r = 0.500), modified Harris Hip Score (r = 0.465), 12-item International Hip Outcome Tool (r = 0.494), VAS pain score (r = -0.346), and VAS satisfaction score (r = 0.459). CONCLUSION: Patients undergoing hip arthroscopy for FAIS derived substantial benefit from each PT visit during their first 13 PT sessions and then a smaller, yet still meaningful benefit from sessions 13 through 27. After session 40, or approximately 4.5 to 5 months, patients no longer benefited from additional PT sessions. Based on PRO scores, patients discharged from PT between 3 and 6 months had the best 2-year outcomes. LEFS score had moderate correlation with orthopaedic PRO scores.

Rehabilitation after arthroscopic Bankart repair: a systematic scoping review identifying important evidence gaps.

BACKGROUND: Evidence to develop best rehabilitation practices after Arthroscopic Bankart Repair (ABR) is lacking, leading to heterogeneity in rehabilitation approaches. OBJECTIVES: This systematic scoping review investigated current evidence for rehabilitation and associated outcomes following ABR, including rehabilitation parameters, evaluative approaches (outcomes/outcome measures, follow-up timing/duration). DATA SOURCES: A systematic search was performed of CINAHL, MEDLINE, and Embase databases in May 2019. STUDY SELECTION: Prospective studies detailing rehabilitation protocols following ABR reporting at least one postoperative assessment within 1 year of surgery (to measure impact of rehabilitation) were included. DATA EXTRACTION AND SYNTHESIS: Two blinded reviewers independently selected studies using standardized criteria and extracted study characteristics and outcomes of interest. Quality of evidence was assessed using Joanna Brigg's quality assessment tool. A narrative analysis was conducted and evidence gaps were identified. RESULTS: Nine studies evaluating 11 rehabilitation protocols with a total of 384 participants were included. Considerable variability was seen in rehabilitation protocols and evaluation parameters. Return to sports/activity was frequently measured, but not well-defined. Strengthening was an important component of rehabilitation protocols, but rarely reported as an outcome. Follow-up was variable, with 4 studies ending follow-up before 24-months postoperatively. Overall, patient outcomes improved postoperatively. CONCLUSIONS: There is a paucity of evidence investigating the impact of rehabilitation approaches following ABR. Although patient outcomes improve after ABR, selected outcomes/measures are highly variable with limited evidence on those important to measure rehabilitation success, particularly strength and return to activity. Identified evidence gaps should be addressed in future research.

The effect of traditional Chinese medicine fumigation and washing as a complementary and alternative therapy on the recovery of joint function after development dysplasia of the hip in children: A protocol for systematic review and meta-analysis.

BACKGROUND: Development dysplasia of the hip (DDH) is a common childhood orthopedic disease in clinic. The cause of DDH is not yet clear. If DDH is not treated promptly or correctly, it will seriously affect the life quality of the child. At present, surgery is the main means of treating older DDH, but it is easy to appear development dysplasia of the hip after surgery, and the joint movement is limited after surgery. For modern medicine, it has not many treatments to solve this problem. As one of the commonly used treatment methods, but the effect of routine functional exercise is not ideal. Traditional Chinese medicine fumigation and washing belongs to the category of Chinese medicine external treatment, which can directly act on the focus. It has the functions of relaxing muscles and tendons and removing obstruction from meridians, activating blood to eliminate stagnation. It has achieved good effects in relieving joint disorders, but it is lack of the high-quality evidence support, so there is controversy about the clinical application of traditional Chinese medicine fumigation and washing. This study will conduct a systematic review to compare the application effect and safety of traditional Chinese medicine fumigation and washing as a complementary and alternative therapy and traditional rehabilitation training in the treatment of postoperative joint function recovery after development dysplasia of the hip in children. The research results will provide evidence-based medical evidence to support the choice of treatment for the disease. METHODS: Using computer to retrieve PubMed, ScienceDirect, Web of Science, EMBase, Cochrane Library, WANFANG Database, CNKI, and VIP Database, CBM, and using the method of combining mesh words with item words to retrieve the Chinese and English databases, to retrieve the randomized controlled study on the application of traditional Chinese medicine fumigation and washing on the recovery of joint function after development dysplasia of the hip in children. The retrieval time is from January 1990 to January 2021. Two researchers screen and evaluate the quality of the retrieved literatures according to the inclusion and exclusion criteria. In the event of a disagreement, a third researcher will join the discussion to resolve the disagreement. Using Revman 5.3 software to conduct meta-analysis. RESULTS: This study will compare the application effect and safety of traditional Chinese medicine fumigation and washing as a complementary and alternative therapy and traditional rehabilitation training in the treatment of postoperative joint function recovery after development dysplasia of the hip in children. CONCLUSION: The results of this study will be published in an internationally influential academic journal to provide evidence-based medical evidence for the selection of supplement and alternative therapies on the recovery of joint function after development dysplasia of the hip in children. ETHICS AND DISSEMINATION: This study does not involve specific patients, and all research data comes from publicly available professional literature, so an ethics committee is not required to conduct an ethical review and approval of this study.

No difference in subjective and objective clinical outcomes between arthroscopic transtibial and open inlay posterior cruciate ligament reconstruction techniques in the treatment of multi-ligamentous knee injuries.

BACKGROUND: There is controversy regarding the optimal treatment of posterior cruciate ligament (PCL) -based multi-ligamentous injuries. The purpose of this study was to compare the subjective and objective clinical outcomes of arthroscopic transtibial reconstruction and tibial inlay reconstruction. METHODS: From 2005 to 2013, a total of 135 patients with PCL-based multi-ligamentous injuries were consecutively identified. Patients were operated with the arthroscopic transtibial technique or the open tibial inlay technique group. Other injured structures were reconstructed or repaired simultaneously. All of the patients underwent a preoperative and postoperative physical examination, KT-1000 measurement, stress radiography under anesthesia and subjective evaluations including Tegner score, Lysholm score, American Academy of Orthopedic Surgeons (AAOS) score. RESULTS: Fifty-seven patients (64.8%) underwent arthroscopic transtibial PCL reconstruction, and 31 patients (35.2%) underwent PCL reconstruction with the tibial inlay technique. The average follow up period was 45.9 ± 17.0 months (24-77 months). At the final follow up, for the arthroscopic transtibial group, the side-to-side difference of KT-1000 decreased from 13.5 ± 4.8 mm to 2.4 ± 3.4 mm (P < 0.001); the tibial posterior translation by stress radiograph decreased from 14.9 ± 7.1 mm to 4.6 ± 4.0 mm (P < 0.001). For the open inlay group, the side-to-side difference of KT-1000 decreased from 13.7 ± 5.2 mm to 2.2 ± 3.6 mm (P < 0.001) and the posterior translation by stress radiograph decreased from 14.9 ± 5.9 mm to 4.3 ± 3.9 mm (P < 0.001) at the final follow up. The inter-group clinical outcomes pre- and postoperatively were not significantly different at any time point. CONCLUSION: There was no statistically significant difference in objective and subjective outcome between the arthroscopic transtibial and open inlay PCL reconstruction in patients with multi-ligamentous injuries.

Do Relaxation Exercises Decrease Pain After Arthroscopic Rotator Cuff Repair? A Randomized Controlled Trial.

BACKGROUND: Pain after rotator cuff repair is commonly managed with opioid medications; however, these medications are associated with serious adverse effects. Relaxation exercises represent a potential nonpharmacologic method of pain management that can be easily implemented without substantial adverse effects; however, the effects of relaxation exercises have not been studied in a practical, reproducible protocol after arthroscopic rotator cuff repair. QUESTIONS/PURPOSES: (1) Does performing relaxation exercises after arthroscopic rotator cuff repair (ARCR) decrease pain compared with standard pain management medication? (2) Does performing relaxation exercises after ARCR decrease opioid consumption? (3) What proportion of patients who used the relaxation techniques believed they decreased their pain level, and what proportion continued using these techniques at 2 weeks? (4) Does performing relaxation exercises after ARCR affect shoulder function? METHODS: During the study period, 563 patients were eligible for inclusion; however, only 146 were enrolled, randomized, and postoperatively followed (relaxation group: 74, control group: 72); 68% (384 of 563) of patients were not contacted due to patient and research staff availability. Thirty-three patients were unenrolled preoperatively or immediately postoperatively due to change in operative procedure (such as, only debridement) or patient request; no postoperative data were collected from these patients. Follow-up proportions were similar between the relaxation and control groups (relaxation: 80%, control: 81%; p = 0.90). The relaxation group received and reviewed educational materials consisting of a 5-minute video and an educational pamphlet explaining relaxation breathing techniques, while the control group did not receive relaxation education materials. Patients recorded their pain levels and opioid consumption during the 5 days after ARCR. Patients also completed the American Shoulder and Elbow Surgeons shoulder score preoperatively and 2, 6, 13, 18, and 26 weeks postoperatively. Linear mixed models were created to analyze postoperative pain, opioid consumption measured in morphine milligram equivalents (MMEs), and shoulder function outcomes. A per-protocol approach was used to correct for patients who were enrolled but subsequently underwent other procedures. RESULTS: There was no difference in pain scores between the relaxation and control groups during the first 5 days postoperatively. There was no difference in pain scores at 2 weeks postoperatively between the relaxation and control groups (3.3 ± 3 versus 3.5 ± 2, mean difference -0.22 [95% CI -1.06 to 0.62]; p = 0.60). There was no difference in opioid consumption during the first 5 days postoperatively between the relaxation and control groups. The use of relaxation exercises resulted in lower 2-week narcotics consumption in the relaxation group than in the control group (309 ± 241 MMEs versus 442 ± 307 MMEs, mean difference -133 [95% CI -225 to -42]; p < 0.01). Sixty-two percent (41 of 66) of patients in the relaxation group believed the relaxation exercises decreased their pain levels. Fifty-two percent (34 of 66) were still performing the exercises at 2 weeks postoperatively. During the 6-month follow-up period, there was no difference in shoulder function between the relaxation and control groups. CONCLUSION: The preoperative administration of quick, basic relaxation exercises allowed patients to use appreciably lower opioid analgesic doses over the first 2 weeks after ARCR, without any worsening of pain scores. We consider this result promising but preliminary; it is possible that a more intense mindfulness intervention-the one we studied here was disseminated using only a 5-minute video-would deliver reductions in pain and further reductions in opioid usage. LEVEL OF EVIDENCE: Level II, therapeutic study.

Short-term effect of electroacupuncture on rehabilitation after arthroscopic triangular fibrocartilage complex repair: a randomised study.

BACKGROUND: Electroacupuncture (EA) alleviates chronic pain and acute postoperative pain after several surgical procedures. However, whether EA facilitates postoperative functional recovery after arthroscopic surgery has yet to be determined. This study investigated the short-term effect of EA on a rehabilitation course after arthroscopic triangular fibrocartilage complex (TFCC) repair. METHODS: Forty-two patients undergoing arthroscopic TFCC repair were randomised to an EA group (n = 19) or control group (n = 23). In the EA group, patients received EA treatment and standard active rehabilitation for 4 weeks. In the control group, patients received standard active rehabilitation for 4 weeks. At the end of the treatment and at the follow-up visit 4 weeks after the treatment, Disabilities of the Arm, Shoulder, and Hand (DASH) scores, wrist range of motion (ROM), handgrip strength, and key pinch strength were collected and analysed. RESULTS: The EA group improved significantly than the control group in terms of DASH scores, all wrist motion arcs, and key pinch strength (P < 0.05) at the end of the 4-week treatment and the follow-up visit another 4 weeks later. CONCLUSION: Patients treated with 4 weeks of EA after the arthroscopic TFCC repair had better wrist ROM and DASH scores than patients of control group.

Comparison of continuous and single interscalene block for quality of recovery score following arthroscopic rotator cuff repair.

BACKGROUND: Continuous interscalene brachial plexus block (CISB) is well known to reduce postoperative pain and to improve patient satisfaction. However, the effect of CISB on the quality of postoperative recovery is unknown. We Compared the quality of recovery from arthroscopic rotator cuff repair in patients who received CISB or single interscalene brachial plexus block (SISB). METHODS: This prospective non-randomized controlled trial with propensity score matching enrolled 134 patients undergoing arthroscopic surgery for rotator cuff repair. Each patient received an interscalene block before surgery. One group had a catheter insertion 30 min after the end of surgery and started patient-controlled regional analgesia (PCRA, n = 49). The other group received intravenous patient-controlled analgesia (IV-PCA, n = 85). The primary outcome was the quality of recovery (QoR-40) score. Also, postoperative analgesia, sleep quality, and postoperative complications were evaluated. RESULTS: The two groups had similar QoR-40 score on postoperative day-1 (POD1), but the PCRA group had a significantly greater QoR-40 score on POD2 (156.0, IQR: 143.0, 169.0 vs. 171.0, IQR: 159.0, 178.0; p < 0.001). The IV-PCA group received more analgesics during the 2 days after surgery, especially during night-time, and had a higher prevalence of sleep disturbances. The time to first additional analgesics request was significantly longer in PCRA group (14 hours, 95% CI: 13-16 vs. 44 hours, 95% CI: 28-not applicable). The incidence of postoperative nausea and vomiting significantly lower in the PCRA group (16.3% vs 46.9%, p = 0.002). CONCLUSION: CISB showed a higher quality of recovery score than SISB with IV-PCA in arthroscopic rotator cuff repair, probably related to the effective analgesia, improved sleep quality, and reduced opioid-related complications.

The effectiveness of traditional Chinese medicine fumigation and washing nursing care after arthroscopic debridement of Knee Osteoarthritis: A protocol for systematic review and meta-analysis.

BACKGROUND: Knee Osteoarthritis (KOA) is a degenerative osteoarthrosis with knee joint pain as the main symptom. In recent years, arthroscopic removal of loose body and repair of meniscus have become common methods for the treatment of KOA. However, postoperative pain, swelling and limited joint movement affect the functional recovery of knee joint and the effect of surgical treatment. Early postoperative control of pain and swelling is of great significance to improve the curative effect of arthroscopic debridement and promote the recovery of knee joint function. In recent years, many clinical studies have reported that the nursing method of fumigation and washing with Chinese medicine after arthroscopic debridement of KOA can relieve pain, promote the recovery of joint function and improve the clinical curative effect, but there is a lack of evidence-based medicine. The purpose of this study is to evaluate the efficacy and safety of fumigation and washing with traditional Chinese medicine after KOA arthroscopy. METHODS: Computer retrieval English database (PubMed, Embase, Web of Science, the Cochrane Library) and Chinese database (China National Knowledge Infrastructure, Wanfang, VIP Database for Chinese Technical Periodicals, China Biology Medicine disc), moreover manual retrieval academic, Google and baidu from building to since December 2020, traditional Chinese medicine fumigation applied to KOA arthroscopy postoperative nursing of randomized controlled clinical research, by two researchers independently evaluated the quality of the included study and extracted the data. Meta-analysis of the included literatures was performed using RevMan5.3 software. RESULTS: The main observation index of this study was the effective rate, and the secondary indexes included Visual Analogue Scale Score, the Western Ontario and McMaster university orthopedic index, Lysholms score and adverse reactions, so as to evaluate the efficacy and safety of traditional Chinese medicine fumigation nursing after KOA arthroscopy. CONCLUSION: This study will provide reliable evidence for the clinical application of Fumigation and washing nursing of traditional Chinese medicine after KOA arthroscopy. ETHICS AND DISSEMINATION: Private information from individuals will not be published. This systematic review also does not involve endangering participant rights. Ethical approval will not be required. The results may be published in a peer-reviewed journal or disseminated at relevant conferences. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/THZP4.

A Comprehensive Enhanced Recovery Pathway for Rotator Cuff Surgery Reduces Pain, Opioid Use, and Side Effects.

BACKGROUND: Patients often have moderate to severe pain after rotator cuff surgery, despite receiving analgesics and nerve blocks. There are many suggested ways to improve pain after rotator cuff surgery, but the effects of adopting a pathway that includes formal patient education, a long-acting nerve block, and extensive multimodal analgesia are unclear. QUESTIONS/PURPOSES: (1) Does adoption of a clinical pathway incorporating patient education, a long-acting nerve block, and preemptive multimodal analgesia reduce the worst pain during the first 48 hours after surgery compared with current standard institutional practices? (2) Does adoption of the pathway reduce opioid use? (3) Does adoption of the pathway reduce side effects and improve patient-oriented outcomes? METHODS: From September 2018 to January 2020, 281 patients scheduled for arthroscopic ambulatory rotator cuff surgery were identified for this paired sequential prospective cohort study. Among patients in the control group, 177 were identified, 33% (58) were not eligible, for 11% (20) staff was not available, 56% (99) were approached, 16% (29) declined, 40% (70) enrolled, and 40% (70) were analyzed (2% [4] lost to follow-up for secondary outcomes after postoperative day 2). For patients in the pathway cohort, 104 were identified, 17% (18) were not eligible, for 11% (11) staff was not available, 72% (75) were approached, 5% (5) declined, 67% (70) enrolled, and 67% (70) were analyzed (3% [3] lost to follow-up for secondary outcomes after postoperative day 2). No patients were lost to follow-up for primary outcome; for secondary outcomes, four were lost in the control group and three in the pathway group after postoperative day 2 (p = 0.70). The initial 70 patients enrolled received routine care (control group), and in a subsequent cohort, 70 patients received care guided by a pathway (pathway group). Of the 205 eligible patients, 68% (140) were included in the analysis. This was not a study comparing two tightly defined protocols but rather a study to determine whether adoption of a pathway would alter patient outcomes. For this reason, we used a pragmatic (real-world) study design that did not specify how control patients would be treated, and it did not require that all pathway patients receive all components of the pathway. We developed the pathway in coordination with a group of surgeons and anesthesiologists who agreed to apply the pathway as much as was viewed practical for each individual patient. Patients in both groups received a brachial plexus nerve block with sedation. Major differences between the pathway and control groups were: detailed patient education regarding reasonable pain expectations with a goal of reducing opioid use (no formal educational presentation was given to the control), a long-acting nerve block using bupivacaine with dexamethasone (control patients often received shorter-acting local anesthetic without perineural dexamethasone), and preemptive multimodal analgesia including intraoperative ketamine, postoperative acetaminophen, NSAIDs, and gabapentin at bedtime, with opioids as needed (control patients received postoperative opioids but most did not get postoperative NSAIDS and no controls received gabapentin or separate prescriptions for acetaminophen). The primary outcome was the numerical rating scale (NRS) worst pain with movement 0 to 48 hours after block placement. The NRS pain score ranges from 0 (no pain) to 10 (worst pain possible). The minimum clinically important difference (MCID) [12] for NRS that was used for calculation of the study sample size was 1.3 [18], although some authors suggest 1 [13] or 2 [5] are appropriate; if we had used an MCID of 2, the sample size would have been smaller. Secondary outcomes included NRS pain scores at rest, daily opioid use (postoperative day 1, 2, 7, 14), block duration, patient-oriented pain questions (postoperative day 1, 2, 7, 14), and patient and physician adherence to pathway. RESULTS: On postoperative day 1, pathway patients had lower worst pain with movement (3.3 ± 3.1) compared with control patients (5.6 ± 3.0, mean difference -2.7 [95% CI -3.7 to -1.7]; p < 0.001); lower scores were also seen for pain at rest (1.9 ± 2.3 versus 4.0 ± 2.9, mean difference -2.0 [95% CI -2.8 to -1.3]; p < 0.001). Cumulative postoperative opioid use (0-48 hours) was reduced (pathway oral morphine equivalent use was 23 ± 28 mg versus 44 ± 35 mg, mean difference 21 [95% CI 10 to 32]; p < 0.01). The greatest difference in opioid use was in the first 24 hours after surgery (pathway 7 ± 12 mg versus control 21 ± 21 mg, mean difference -14 [95% CI -19 to -10]; p < 0.01). On postoperative day 1, pathway patients had less interference with staying asleep compared with control patients (0.5 ± 1.6 versus 2.6 ± 3.3, mean difference -2.2 [95% CI -3.3 to -1.1]; p < 0.001); lower scores were also seen for interference with activities (0.9 ± 2.3 versus 1.9 ± 2.9, mean difference -1.1 [95% CI -2 to -0.1]; p = 0.03). Satisfaction with pain treatment on postoperative day 1 was higher among pathway patients compared with control patients (9.2 ± 1.7 versus 8.2 ± 2.5, mean difference 1.0 [95% CI 0.3 to 1.8]; p < 0.001). On postoperative day 2, pathway patients had lower nausea scores compared with control patients (0.3 ± 1.1 versus 1 ± 2.1, mean difference -0.7 [95% CI -1.2 to -0.1]; p = 0.02); lower scores were also seen for drowsiness on postoperative day 1 (1.7 ± 2.7 versus 2.6 ± 2.6, mean difference -0.9 [95% CI - 1.7 to -0.1]; p = 0.03). CONCLUSION: Adoption of the pathway was associated with improvement in the primary outcome (pain with movement) that exceeded the MCID. Patients in the pathway group had improved patient-oriented outcomes and fewer side effects. This pathway uses multiple analgesic drugs, which may pose risks to elderly patients, in particular. Therefore, in evaluating whether to use this pathway, clinicians should weigh the effect sizes against the potential risks that may emerge with large scale use, consider the difficulties involved in adapting a pathway to local practice so that pathway will persist, and recognize that this study only enrolled patients among surgeons and the anesthesiologists that advocated for the pathway; results may have been different with less enthusiastic clinicians. This pathway, based on a long-lasting nerve block, multimodal analgesia, and patient education can be considered for adoption. LEVEL OF EVIDENCE: Level II, therapeutic study.

Acetabular Rim Disorders/Pincer-type Femoroacetabular Impingement and Hip Arthroscopy.

Femoroacetabular impingement (FAI) can lead to acetabular impaction, chondral injury, and labral pathology secondary to deformities of the proximal femur (CAM-type FAI), acetabulum (pincer-type FAI), or with combined FAI. While the majority of cases are of the combined type, this paper focuses on acetabular overcoverage/pincer-type deformities. Various pincer subtypes include focal anterior overcoverage, global retroversion, global overcoverage/profunda, protrusio, subspine impingement, and os acetabuli/rim fracture variants. A thorough history and physical examination, plain radiographs, magnetic resonance imaging, 3-dimensional computerized tomography, and diagnostic injections can lead to an accurate assessment of pincer-type variants. Appropriately indicated arthroscopic management techniques and pearls for the various pincer subtypes can lead to improved patient-related outcome measures and a high rate of return to athletic activity for the majority of these patients.

Clinical outcomes of a combined arthroscopic and mini-open Outerbridge-Kashiwagi procedure for elbow osteoarthritis.

BACKGROUND: To evaluate the short-term clinical outcomes of a modified Outerbridge-Kashiwagi (O-K) procedure in the treatment of elbow osteoarthritis. METHODS: Between January 2012 and December 2016, 27 patients with elbow osteoarthritis were treated with a modified O-K procedure combining mini-open and arthroscopic technique in our institution. All patients with primary osteoarthritis and post-traumatic degenerative osteoarthritis of the elbow were included in the study if they had undergone the modified O-K procedure. Clinical outcomes were assessed using the visual analog scale (VAS), degree of flexion, extension loss, arc of motion, Mayo Elbow Performance Score (MEPS), and radiographs. RESULTS: Twenty-five patients with a mean age of 47.2 years (range, 21-69 years) at surgery were followed up for a mean of 54.5 months (range, 27-86 months). The VAS improved from 8.0 ± 1.4 (range, 6-10) preoperatively to 1.3 ± 1.1 (range, 0-3) at the final follow-up (P < .001), degree of flexion from 115.2° ± 12.0° (range, 90°-135°) to 130.6° ± 6.3° (range, 120°-140°) (P < .001), extension loss from 31.2° ± 15.0° (range, 10°-60°) to 10.2° ± 7.7° (range, 0°-30°) (P < .001), arc of motion from 84.0° ± 18.8° (range, 55°-120°) to 120.4° ± 9.3° (range, 105°-135°) (P < .001), and MEPS from 55.8 ± 8.1 (range, 40-70) to 88.4 ± 7.2 (range, 70-100) (P < .001). Radiographs at the final follow-up showed that 9 patients (36%) had significant recurrence of bone formation within the fenestration of the olecranon fossa. One patient developed delayed-onset ulnar neuropathy, with only slight numbness in the ulnar nerve distribution 6 months after surgery. CONCLUSIONS: The modified O-K procedure is safe and effective in pain relief and function restoration in patients with elbow osteoarthritis.

The Bony Bankart: Clinical and Technical Considerations.

Fractures of the anteroinferior aspect of the glenoid rim, known as a bony Bankart lesions, can occur frequently in the setting of traumatic anterior shoulder dislocation. If these lesions are large and are left untreated in active patients, then recurrent glenohumeral instability due to glenoid bone deficiency may occur. Therefore, the clinician must recognize these lesions when they occur and provide appropriate treatment to restore physiological joint stability. This article aims to provide an overview focusing on clinical and technical considerations in the diagnosis and treatment of bony Bankart lesions.

Rehabilitation After Shoulder Instability Surgery: Keys for Optimizing Recovery.

The specific approach to rehabilitation after surgical management of the unstable shoulder is dependent on the severity and chronicity of the instability. Establishing dynamic stability throughout the athlete's functional range of movement is critical to a successful outcome. The pace progression is guided by surgical (technique, injury pattern, and strength of repair) and patient factors (healing potential, prior health status, and psychosocial factors). The primary goal of treatment is to restore function and return the athlete to sport. The process should be guided by surpassing functional criteria for progression and tissue healing time.

Comparing racing performance following arthroscopic surgery of metacarpophalangeal/metatarsophalangeal and carpal joints in Thoroughbred racehorses rehabilitated using conventional and underwater treadmill therapies.

BACKGROUND: Rehabilitation of horses using underwater treadmill therapy has been shown to improve joint range of motion, joint mobility, stride length and proprioceptive parameters with experimental studies. However, studies investigating the prognosis and return to function following rehabilitation are lacking. METHODS: A retrospective study of Thoroughbred racehorses treated with arthroscopic surgery for osteochondral fragments of the metacarpophalangeal (MCP) or metatarsophalangeal (MTP) joints or carpal joints undergoing conventional rehabilitation or underwater treadmill assisted rehabilitation at the same facility were included. The objective of the current study was to investigate if underwater treadmill assisted rehabilitation following arthroscopy in the Thoroughbred racehorse was positively associated with returning to racing, time to return to racing and postoperative racing performance including Beyer Speed Figures. RESULTS: Surgery was performed on 165 horses on 174 surgical occasions; 70 (40.2 per cent) underwent underwater treadmill rehabilitation, with the remainder undergoing conventional rehabilitation. The time to return to racing was a median of 227 (IQR 185-281) days and 239 (IQR 205-303) days for underwater treadmill and conventional rehabilitation, respectively (P=0.16). Of the horses that raced presurgery, 83 per cent (58/70) of underwater treadmill rehabilitated horses and 61 per cent (63/104) of horses undergoing conventional rehabilitation returned to racing following surgery (P=0.02). CONCLUSION: Underwater treadmill rehabilitation is superior in returning a Thoroughbred racehorse to racing following arthroscopic surgery of the carpus and/or MCP/MTP joints.

There is a correlation between histopathological findings of joint capsule and synovium, and postoperative clinical outcomes and treatment in patients with isolated type II superior labrum anterior posterior lesions.

OBJECTIVES: This study aims to histologically examine the joint capsule and synovium to determine the correlation between histopathological findings and postoperative clinical outcomes in patients with isolated type II superior labrum anterior posterior (SLAP) lesions. PATIENTS AND METHODS: Thirty-eight patients (24 males, 14 females; mean age 53.2±6.6 years; range, 45 to 67 years) who underwent arthroscopic treatment of type II SLAP lesions between June 2017 and September 2018 were evaluated prospectively. Visual analog scale (VAS), Simple Shoulder Test (SST), and American Shoulder and Elbow Surgeons (ASES) scores of all patients were recorded preoperatively, and at 6th and 12th months postoperatively. Biceps tenotomy was applied as arthroscopic surgical treatment in all patients. Biopsy materials obtained from rotator interval joint capsule and synovium during the arthroscopy were evaluated histopathologically. The density of the vessels in the specimens was defined as low, medium, and high by the pathologist. The patients with medium or low vessel density in specimens were group 1 (n=14) and those with high vessel density group 2 (n=24). RESULTS: In group 2, preoperative VAS score was significantly higher. There was no difference between the scores of the groups except for the sixth month SST score which was significantly higher in group 1. Histopathological evaluation revealed that the number of lymphocytes, fibroblasts, mast cells, myofibroblast, synovial lining cells, macrophages, and amount of collagen in connective tissue were significantly higher in group 2. In five patients of group 2, the rehabilitation program was interrupted due to pain and difficulty in gaining a range of motion during the first four weeks postoperatively. Four of these patients recovered with medication and long-duration physiotherapy. Shoulder stiffness developed in one patient who required arthroscopic release and further rehabilitation. CONCLUSION: There is a correlation between histopathological findings of joint capsule and synovium, and postoperative clinical outcomes and treatment in patients with isolated type II SLAP lesions. Almost 20% of patients who had pathologic histological findings in joint capsule and synovium needed pain control and long-duration rehabilitation program after arthroscopic surgery for better shoulder function recovery and prevention of shoulder stiffness.

Postoperative rehabilitation and outcomes following arthroscopic isolated meniscus repairs: A systematic review.

OBJECTIVES: The purpose of this study was to review the current literature on rehabilitation protocols following arthroscopic meniscus repair. METHODS: A systematic literature review was performed of Medline, Scopus, and Web of Science databases to identify relevant articles from January 1990 to April 2019. Search terms were (meniscus OR meniscal repair) AND (repaired OR repair) AND (rehabilitation OR physiotherapy OR physical therapy). Each study was independently scored for methodological research quality level using the Modified Coleman Methodology Score (MCMS). The following variables were extracted from each study: publication year, study type, evidence level, subject demographics, injury mechanism, meniscus tear type, surgical procedure, rehabilitation program [immobilization, weight bearing, ROM progression, therapeutic exercises, length of follow-up, patient-reported outcome measurements, return to sport timing/criteria and failure rate/criteria. RESULTS: Eighteen studies met the inclusion criteria. The overall MCMS was moderate 59.5 ± 11.7 (range = 42-90). The average MCMS score for postoperative rehabilitation was 4.7 ± 1.18. Only 1 (5.6%) study was a prospective randomized controlled trial and 14 studies (78%) had retrospective designs. Fourteen (78%) studies suggested that return to sports should occur between 3 and 6 months post-surgery. Early range of motion and immediate weight-bearing had no influence over patient-reported outcomes or failure rates for vertical meniscus tear repairs. CONCLUSION: Low MCMS scores, primarily retrospective study designs and poorly described postoperative rehabilitation protocols made it difficult to design an evidence-based therapeutic rehabilitation program for patients following arthroscopic repair of an isolated meniscus tear. An arthroscopic isolated meniscal tear repair rehabilitation protocol is being attempted to present based on a synopsis of existing evidence.

Arthroscopic Latarjet for Shoulder Instability.

Arthroscopic Latarjet is a relatively new, but viable option for the treatment of anterior shoulder instability. Arthroscopic Latarjet has the advantage of faster recovery, reduced stiffness, identification of additional shoulder pathology, and improved cosmesis when compared with open Latarjet. By the majority of clinical and radiographic parameters, arthroscopic Latarjet produces equivalent outcomes compared with open Latarjet. A relatively substantial learning curve for arthroscopic Latarjet exists at about 25 cases; however, multiple studies have demonstrated comparable outcomes and surgical time after the learning curve.
