Arthroscopic hip procedures have increased dramatically over the last decade as equipment and techniques have improved. Patients who require hip arthroscopy for femoroacetabular impingement on occasion require surgery on the contralateral hip. Previous studies have found that younger age of presentation and lower Charlson comorbidity index have higher risk for requiring surgery on the contralateral hip but have not found correlation to anatomic variables. The purpose of this study is to evaluate the factors that predispose a patient to requiring subsequent hip arthroscopy on the contralateral hip. This is an IRB-approved, single surgeon retrospective cohort study from an academic, tertiary referral centre. A chart review was conducted on 310 primary hip arthroscopy procedures from 2009-2020. We identified 62 cases that went on to have a hip arthroscopy on the contralateral side. The bilateral hip arthroscopy cohort was compared to unilateral cohort for sex, age, BMI, pre-op alpha angle and centre edge angle measured on AP pelvis XRay, femoral torsion, traction time, skin to skin time, Tonnis grade, intra-op labral or chondral defect. A p-value <0.05 was deemed significant. Of the 62 patients that required contralateral hip arthroscopy, the average age was 32.7 compared with 37.8 in the unilateral cohort (p = 0.01) and BMI was lower in the bilateral cohort (26.2) compared to the unilateral cohort (27.6) (p=0.04). The average alpha angle was 76.3. 0. in the bilateral compared to 66. 0. in the unilateral cohort (p = 0.01). Skin to skin time was longer in cases in which a contralateral surgery was performed (106.3 mins vs 86.4 mins) (p=0.01). Interestingly, 50 male patients required contralateral hip arthroscopy compared to 12 female patients (p=0.01). No other variables were statistically significant. In conclusion, this study does re-enforce existing literature by stating that younger patients are more likely to require contralateral hip arthroscopy. This may be due to the fact that these patients require increased range of motion from the hip joint to perform activities such as sports where as older patients may not need the same amount of range of motion to perform their activities. Significantly higher alpha angles were noted in patients requiring contralateral hip arthroscopy, which has not been shown in previous literature. This helps to explain that larger CAM deformities will likely require contralateral hip arthroscopy because these patients likely impinge more during simple activities of daily living. Contralateral hip arthroscopy is also more common in male patients who typically have a larger CAM deformity. In summary, this study will help to risk stratify patients who will likely require contralateral hip arthroscopy and should be a discussion point during pre-operative counseling. That offering early subsequent or simultaneous hip arthroscopy in young male patients with large CAMs should be offered when symptoms are mild

As the field of hip arthroscopy continues to develop, functional measures and testing become increasingly important in patient selection, managing patient expectations prior to surgery, and physical readiness for return to athletic participation. The Hip Sport Test (HST) was developed to assess strength, coordination, agility, and range of motion prior to and following hip arthroscopy as a functional assessment. However, the relationship between HST and hip strength, range of motion, and hip-specific patient reported outcome (PRO) measures have not been investigated. The purpose of this study was to evaluate the correlation between the HST scores and measurements of hip strength and range of motion prior to undergoing hip arthroscopy. Between September 2009 and January 2017, patients aged 18-40 who underwent primary hip arthroscopy for the treatment of femoroacetabular impingement with available pre-operative HST, dynamometry, range of motion, and functional scores (mHHS, WOMAC, HOS-SSS) were identified. Patients were excluded if they were 40 years old, had a Tegner activity score < 7, or did not have HST and dynamometry evaluations within one week of each other. Muscle strength scores were compared between affected and unaffected side to establish a percent difference with a positive score indicating a weaker affected limb and a negative score indicating a stronger affected limb. Correlations were made between HST and strength testing, range of motion, and PROs. A total of 350 patients met inclusion criteria. The average age was 26.9 ± 6.5 years, with 34% females and 36% professional athletes. Total and component HST scores were significantly associated with measure of strength most strongly for flexion (rs = −0.20, p < 0 .001), extension (rs = −0.24, p<.001) and external rotation (rs = −0.20, p < 0 .001). Lateral and diagonal agility, components of HST, were also significantly associated with muscle strength imbalances between internal rotation versus external rotation (rs = −0.18, p=0.01) and flexion versus extension (rs = 0.12, p=0.03). In terms of range of motion, a significant correlation was detected between HST and internal rotation (rs = −0.19, p < 0 .001). Both the total and component HST scores were positively correlated with pre-operative mHHS, WOMAC, and HOS-SSS (p<.001 for all rs). The Hip Sport Test correlates with strength, range of motion, and PROs in the preoperative setting of hip arthroscopy. This test alone and in combination with other diagnostic examinations can provide valuable information about initial hip function and patient prognosis

Abstract. Introduction. The extent to which hip arthroscopy (HA) treatments influence sexual function is not well described and limited to small cohorts. This study aims to describe trends in self-reported reported sexual function before and after HA. Methods. Adult (≥18 years) patients who underwent HA between 1/01/2012 and 31/10/2020 were extracted from the UK Non-Arthroplasty Hip Registry. International Hip Outcome Tool 12 (iHOT-12) questionnaires were collected pre-operatively and at 6 and 12 months. The iHOT-12 then asks asking patients to quantify ‘how much trouble they experience with sexual activity because of their hip?’ with responses converted to a continuous scale (0–100) to measure function. Results. Of 7639 procedures (59% female, mean age 36.5 years (SD 11)), 91% (5616 of 6151 respondents) indicated pre-operatively that questions about sexual activity were relevant to them (male 93%, female 90%, p < 0.001). Overall, mean pre-operative sexual function increased from 42.0 (95%CI 41.2 to 42.8, n=5267) to 61.8 (60.6 to 63.1, n=2393) at 6 months, and 62.1 (60.8 to 63.5, n=2246) at 12 months post-operatively. At 12 months, both sexes saw significant improvement in their pre-operative sexual function scores (p<0.0001). Males started from significantly higher baseline sexual function (53.3 vs 34.2) and achieved higher scores by 12 months (68.8 vs 58.0) compared to female patients. There was no significant difference in pre- or post-operative scores when comparing younger (<40 years) and older (>40 years). Conclusions. Most patients can expect to experience improvement in their sexual function following hip arthroscopy, regardless of sex or age group

In the young and highly active population of military patients, femoroacetabular impingement can be a source of serious disability as well as a threat to their career. This morbidity can be treated with hip arthroscopy with debridement of cam lesion, and excision or repair of a corresponding labral tear. We report on the long term outcomes (>1 year) of 26 military cases who underwent hip arthroscopy for femoroacetabular impingement, in a single surgeon's series. Twenty two patients (four bilateral cases) underwent hip arthroscopy as a day case procedure during the period February 2013 to October 2014. Non-Arthritic Hip Scores (NAHS) were obtained from patients pre-operatively, at two months, four months and at least one year post-operatively. There was a significant improvement in NAHS at two months (75.6)(p<0.05), four months (85.1)(p<0.001) and one year (84.8)(p<0.001), compared to pre-operative NAHS (65.8). There was no significant change in NAHS beyond four months. Only three out of the 22 patients were medically discharged secondary to persistent hip symptoms. Hip arthroscopy for femoroacetabular impingement is an effective, viable procedure for military patients. Mobility, pain and function is significantly improved after surgery. This improvement is sustained in the long term up to and beyond one year

Background. Hip arthroscopy is well established as a diagnostic and therapeutic tool in the native hip joint. However, its application in the symptomatic post-hip arthroplasty patient is still being explored. Aims and Methods. We have described the use of hip arthroscopy in symptomatic patients following total hip replacement, resurfacing hip arthroplasty and partial resurfacing hip arthroplasty in 24 patients (study group), and compared it with arthroscopy of the native hip of 24 patients. Results. The diagnostic yield of hip arthroscopy in symptomatic post-arthroplasty patients was 95.8% (23 / 24) and a therapeutic arthroscopic intervention resulted in relief of symptoms in 41.6% (10 / 24) of the patients. It led to revision hip replacement in a further 29.1% (7 / 24). In contrast, hip arthroscopy of the native hip (control group) had a 100% diagnostic yield and an arthroscopic therapeutic intervention was carried out in all the patients resulting in symptomatic relief in 87.5% (21 / 24). The mean operative time in the study group (59.7 mins, SD 21.1) was less than the control group (71 mins, SD 17.1, p < 0.05) but the arthroscopic approach was more difficult. Conclusion. The authors suggest the use of hip arthroscopy in well-investigated symptomatic post-arthroplasty patients with an elusive diagnosis (Fig. 1: Arthroscopic image showing a THR in situ (Furlong, JRI, London, UK) with a ceramic femoral head (yellow arrow), ceramic acetabular liner (white arrow), florid metallosis (red arrow) and corrosion on the femoral neck (green arrow) because of impingement against the margin of the acetabular component.) and also describe the technical modifications necessary with various types of hip arthroplasty

Aim. The aim of this study was to assess the role of hip arthroscopy in the management of hip pain in elite athletes. Patients and methods. It is a retrospective study of prospectively collected data. 31 hip arthroscopies were performed on 27 elite athletes. All the patients were assessed pre-operatively with a thorough clinical examination, radiographs and MRI scans. The modified HHS was also recorded for all the patients' pre and post-operatively. All operations were performed by the senior author, and the patients were assessed at 6 weeks, 3 months, 6 months and a year following the operation. Results. The M:F ratio was 25:2 with an average age of 38 years (Range: 18-58) in the study group. 65% of the patients were professional football players followed by cricket and tennis. The patients were referred at an average of 506 days. Two of the 27 patients demonstrated minimal acetabular dysplasia on their pre-operative radiographs. Of the 31 arthroscopies, a primary diagnosis of a labral tear was made in 20, a chondral flap and delamination in 5, early osteoarthritis in 4 and a ligamentum teres tear in 2. Along with the primary diagnosis of a labral tear, twelve of the 20 patients had a secondary diagnosis of chondral injury and or Femeroacetabular Impingement as well. There were no complications reported. Conclusions. Hip Injuries in athletes are reported late and Chondral Flaps and Ligamentum teres tears are under-diagnosed. Most athletes have a good chance to return back to the original level of sport within 4 months following hip arthroscopy. However, about 40% do continue to have some form of pain. Hip arthroscopy is a safe and effective method for diagnosis and treatment of intra-articular disorders in elite athletes

Introduction. Hypothermia is the drop in body temperature under 35°C (95°F), It has implications in immunological function and healing process, increasing the infection and the cardiovascular risk. During hip arthroscopy patients are exposed to several risk factors that may lead to hypothermia. Objective. to determinate if there are hypothermia and which are the factors contributing to hypothermia during hip arthroscopy. Methods and materials. we developed an prospective observational analytical study in a cohort group of patients that went to a hip arthroscopy, all operated by a single surgeon for treatment of femoroacetabular impingement, all were done under general anesthesia in supine position, with vair hugher warmer body air convection system always in 43.3°C; and we registered central body temperature (esophagical) during the entire procedure, we also recorded operation room temperature, volume (liters) and temperature of the saline solution used for the arthroscopy, age of the patient, body mass index (BMI), arterial tension, pump pressure, and surgical time. We analyzed the results with STATA 10.0 statistical software. Results. we performed 12 cases, 30 years old in average (14 – 46), BMI 24.0 in average (18.7 – 30.4), and hypothermia was founded in 16% (2/12) of cases. There are a direct assosiation between hypothermia and operating time over 120 minutes (p <0,001) (fig.1). Despite the rest of the parameters we didn't find any other correlation. Conclusion. Hypothermia is present in 16,67% of the patients, during hip arthroscopy for the treatmemt of femoroacetabular impingement, are group is small but we demonstrated a direct correlation between operating time and hypothermia, further studys with larger groups should be performer to identify the correlations and risk factors for hypothermia in these patients

We present a prospective two-year follow-up study of 1038 hip arthroscopies performed at a high volume tertiary referral centre for hip preservation. We feel that this manuscript is both pertinent and timely due to the advances in the field of hip preservation. We used four validated patient-reported outcome (PRO) scores along with the visual analog scale (VAS) and patient satisfaction scores to assess preoperative and postoperative outcomes in all patients undergoing hip arthroscopy. We divided the entire cohort into patients undergoing primary and revision hip arthroscopies. We found a statistically significant improvement from preoperative to two-year postoperative PRO scores in the two subgroups. We also found a significant difference in the PRO scores at three months, one year, and two years postoperatively between the primary and revision subgroups. The revision subgroup had inferior VAS and patient satisfaction compared to the primary subgroup, however these results were not significant. The conversion to total hip arthroplasty/hip resurfacing (THA/HR) was 5.6% and 11.2% in the primary and revision subgroups, respectively. This resulted in a relative risk of 2.0 for conversion to THA/HR in the revision subgroup. We had a complication rate of 5.3 (only 0.5% of which were considered major) which was similar to that reported in the literature for hip arthroscopy. The primary purpose was to perform a survival analysis in a large mixed cohort of patients undergoing hip arthroscopy at a high volume tertiary referral centre for hip preservation with minimum two-year follow-up. The secondary purpose was to compare clinical outcomes of primary versus revision hip arthroscopy. From February 2008 to June 2012, data were prospectively collected on all patients undergoing primary or revision hip arthroscopy. Patients were assessed pre- and post-operatively with modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Activities of Daily Living (HOS-ADL), and Hip Outcome Score-Sport Specific Subscales (HOS-SSS). Pain was estimated on the visual analog scale (VAS). Patient satisfaction was measured on a scale from 0 to 10. There were a total of 1155 arthroscopies performed, including 1040 primary arthroscopies (926 patients) and 115 revision arthroscopies (106 patients). Of these, 931 primary arthroscopies (89.5%) in 824 patients (89.0%) and 107 revision arthroscopies (93.0%) in 97 patients (91.5%), were available for follow-up and included in our study. The mean change in patient reported outcome (PRO) scores at two-year follow-up in the primary subgroup was 17.4 for mHHS, 19.7 for HOS-ADL, 23.8 for HOS-SSS, 21.3 for NAHS, and −3.0 for VAS. The mean change in PRO scores at two-year follow-up in the revision subgroup was 13.4, 10.9, 16.1, 15.4, and −2.7, respectively. All scores improved significantly compared to pre-operatively (p<0.001). PRO scores were higher at all time points for the primary subgroup compared to the revision subgroup (p<0.05). Satisfaction was 7.7 and 7.2 for primary and revision subgroups, respectively. Of 931 primary arthroscopies, 52 (5.6%) underwent THA/HR. Of 107 revision arthroscopies, 12 (11.2%) underwent THA/HR. The relative risk of a THA/HR was 2.0 after revision procedures compared to primary procedures. The overall complication rate was 5.3%. Hip arthroscopy showed significant improvement in all PRO, VAS, and satisfaction scores at two years postoperatively. Primary arthroscopy patients showed greater PRO scores and a trend towards greater VAS compared to the revision subgroup. The relative risk of a THA/HR was 2.0 after revision procedures compared to primary procedures

Hip arthroscopy is becoming more popular. A literature review demonstrated paucity of published papers reporting the outcome of hip arthroscopy in teenagers without developmental dysplasia of the hip. Our aim was to record the type of lesions found and report the outcome and level of satisfaction following hip arthroscopy in teenagers. From 2002 to 2008, 96 hip arthroscopies were undertaken in 76 patients. Pre-operative and two-week, six-week and current post-operative assessments were performed using the modified Harris hip score (HHS) and the Non Arthritic Hip Score (NAHS). In addition, a satisfaction survey was completed at their most recent review. Patients enrolled in the study were under the age of 20. Patients with a history of developmental dysplasia of the hip, Perthes disease and arthritis were excluded from the study. Patients had at least a six-month follow-up from their surgery. Our study cohort comprised 53 males and 43 females with an average age of 17 years old (range 13 to 19 years). The average duration of follow up was 19 months (range 3 to 75 months). There were 41 left and 54 right-sided hip arthroscopies. There were five re-operations. The average duration of hip traction was 19 minutes (range 6 to 47 minutes). We found pathology in all hips that underwent arthroscopy. We report a significant improvement in MHHS and NAHS at six weeks and current review (p-value <0.01). Sixty-two percent of patients had returned to sport at the previous level of competition, 32% of patients returned to sport at a lower level of competition and 5% patients did not return to sport. Overall, 84% of patients were satisfied following their hip arthroscopy and 91% would have the surgery again if they had to. There were five re-operations. Our study has revealed a range of intra articular hip pathologies amenable to surgical treatment using hip arthroscopy. We have observed a significant improvement in hip scores; with up to 94% of patients returning to sport in the short term with high satisfaction levels. Long term follow up of this group is ongoing

Orthopaedic surgeons frequently use opioids for peri-operative pain management and there is considerable variability in the amount prescribed between surgeons. As such, the appropriate number of opioids to prescribe for specific procedures is often unknown. Leftover prescription opioids are at risk for diversion to family and friends for nonmedical use. The aim of this study was to determine the optimal amount of narcotics to prescribe postoperatively for patients undergoing hip arthroscopy. 23 consecutive patients were enrolled. All patients were prescribed 60 tablets of hydrocodone/acetaminophen 10/325 postoperatively as part of a multimodal pain management strategy. Patients were called at 14 and 21 days post-operatively to tabulate the number of pills used and knowledge of how to properly dispose of pills. The median number of narcotic pain pills required was 6 (IQR: 3,15). Over half of patients (56.5%) required ≤10 narcotic pain pills postoperatively. A large number of narcotic tablets (1071/1380, 77.6%) were unused and a small percentage of patients (8/23, 34.8%) were aware of proper disposal techniques. Knowledge of how to properly dispose of unused narcotics was protective against a prolonged duration of narcotic use postoperatively (Parameter estimate −5.7, 95% CI: −11.3, −0.1, p = 0.045). Reducing the number of prescribed narcotic tablets to 25 would meet the post-operative pain demands of over 85% of hip arthroscopy patients. More judicious post-operative prescribing patterns and patient education regarding disposal may help minimize physician contribution to opioid misuse, overuse and diversion

Introduction. With the evolution of hip arthroscopy, it has been used as joint preserving surgery for osteoarthritis among various other indications. The purpose of this study was to assess the factors that affect the subgroup of patients with osteoarthritis that have had total hip replacements following hip arthroscopy. Methods. Data was retrieved retrospectively from 556 osteoarthritic patients' files that have had hip arthroscopy between the years 2002 to 2009 (mean follow up time 3.2 – range 1 to 6.4 years). Eighty-three (15%) of them have had eventually total hip replacement. The data analysis included different variables (i.e. age, arthritic stage, repeated procedures) that may have influenced the time elapsed between the hip arthroscopy and consecutive replacement procedures. Results. The time gap from the first arthroscopy to a hip replacement was longer in patients younger than 55 years (mean 1.9 – range 0.2 to 5.1 years) and in a milder osteoarthritic stage (mean 2.2 – range 0.2 to 5 years). Patients that had several hip scopes (2 to 4) had a double time gap (mean 2.8 – range 1.4 to 4.7 years) than those with only a single procedure. Conclusion. Osteoarthritic patients that are treated with hip arthroscopy have 15% chance of having a hip replacement within the period of seven years. The time difference for a hip replacement after an arthroscopy is longer in younger age and in milder osteoarthritis. Repeated arthroscopies may delay the need for arthroplasty

Previous authors have suggested that the analgesic effects of intra-articular morphine may be beneficial. Clonidine has been found to potentiate the analgesic effect of morphine. Following knee arthroscopy, morphine has demonstrated equivocal effect in comparison to bupivicaine for analgesia while circumventing the issue of chondrotoxicity. There have been no studies evaluating the effect of intra-articular morphine following hip arthroscopy. The purpose of this study was to evaluate the efficacy of intra-articular morphine in combination with clonidine on pain and narcotic consumption following hip arthroscopy surgery for femoroacetabular impingement. A retrospective review was performed on 43 patients that underwent hip arthroscopy between September 2014 and May 2015 at our institution for femoroacetabular impingement. All patients received preoperative Celebrex and Tylenol per our anesthesia protocol, and 22 patients received an additional intra-articular injection of 10 mg morphine and 100 mcg of clonidine at the conclusion of the procedure. Narcotic consumption, duration of anesthesia recovery, and perioperative pain scores were compared between the two groups. We found that patients who received intra-articular morphine and clonidine used significantly less opioid analgesic in the PACU, with 23 mEq of morphine equivalents required in the intra-articular morphine and clonidine group compared to 40 mEq of opiod equivalents in the non-injection group (p=0.0259). There were no statistically significant differences in time spent in recovery prior to discharge or in VAS pain scores recorded immediately post-operatively and at one hour following surgery. In conclusion, we found that an intraoperative intra-articular injection of morphine and clonidine significantly reduced the amount of narcotic requirement following hip arthroscopy. We do believe that there may be significant benefits to this, including less systemic effects from overall narcotic usage in the perioperative period. Our study demonstrated a beneficial effect of intra-articular morphine that may help with overall pain improvement, less narcotic consumption, and improved patient satisfaction following outpatient hip arthroscopy. This study provides the foundation for future research currently being conducted in a randomised-control setting

The risk that hip preserving surgery may negatively influence the performance and outcome of subsequent total hip replacement (THR) remains a concern. The aim of this study was to identify any negative impact of previous hip arthroscopy on THR. Out of 1271 consecutive patients who underwent primary THR between 2005 and 2009, eighteen had previously undergone ipsilateral hip arthroscopy. This study group (STG) was compared with two control groups (CG: same approach, identical implants; MCG: paired group matched for age, BMI and Charnley categories). Operative time, blood loss, evidence of heterotopic bone and implant loosening at follow-up were compared between the SG and the MCG. Follow-up WOMAC were compared between the three groups. Blood loss was not found to be significantly different between the SG and MCG. The operative time was significantly less (p>0.001) in the SG. There was no significant difference in follow-up WOMAC between the groups. No implant related complications were noted on follow-up radiographs. Two minor complications were documented for the SG and three for the MCG. We have found no evidence that previous hip arthroscopy negatively influences the performance or short-term outcome of THR

Health care facilities are major contributors of waste to landfills, with operating rooms estimated to assume 20–70% of this waste. With hip arthroscopy for femoroacetabular impingement (FAI) on the rise, it is important to understand its environmental impact and identify areas for greening practices. Given its minimally-invasive nature, we hypothesise overall arthroscopic waste per FAI patient case to be approximately 5 kg, with minimal biohazard waste. The purpose of this study was to determine the amount of waste produced in FAI procedures and understand the environmental impact of the procedure to aid us in developing greening practices. A single surgeon waste audit (with descriptive statistics) of five FAI hip arthroscopy procedures – categorised by: 1) normal/landfill waste; 2) recyclable cardboards and plastics; 3) biohazard waste; 4) sharp items; 5) linens; and 6) sterile wrapping – was performed in April 2015. The surgical waste (except laundered linens) from the five FAI surgeries totalled 47.4 kg, of which 21.7 kg (45.7%) was biohazard waste, 11.7 kg (24.6%) was sterile wrap, 6.4 kg (13.5%) was normal/landfill waste, 6.4 kg (13.5%) was recyclable plastics, and 1.2 kg (2.6%) was sharp items. There was an average of 9.4 kg (excluding laundered linens) of waste produced per procedure. Considerable waste, specifically biohazard waste, is produced in FAI procedures with an average of 9.4 kg of waste produced per procedure, including 4.3 kg of biohazard waste. In Canada (population 35.7 million), approximately 18 800 kg of waste (8600 kg of biohazard waste) is produced from an estimated 2000 FAI procedures performed every year. Additional recycling programs, reducing surgical overage, and continued adherence to proper waste segregation will be helpful in reducing waste production and its environmental burden. An emphasis on “green outcomes” is also required to demonstrate environmental responsibility and effectively manage and allocate finite resources

Introduction. The outcome of periacetabular osteotomy in dysplastic hips is dependent on the absence of pre-operative osteoarthritis [OA]. The purpose of this study was to analyze whether Tonnis grading is a reliable predictor of OA in patients with hip dysplasia. Methods. Thirty patients were identified who had undergone hip arthroscopy surgery to assess their suitability for periacetabular osteotomy. Radiographs were assessed for anterior centre edge angle, lateral centre edge angle, Tonnis angle and Tonnis grade for OA changes. The radiographic grading of OA was compared with arthroscopic findings. Results. The average age at the time of arthroscopy was 35 [16–53 yrs] (28 females). Tonnis grade did not correlate with arthroscopic findings (p=0.082). There was a trend for patients with a higher Tonnis grade to have more OA changes. Of the 30 patients, all 3 with grade 0 were fit for periacetabular osteotomy, while only 8 out of 24 with grade I, and 1 out of 3 with grade II were fit for periacetabular osteotomy. Discussion. This study reports that even when radiographic grading showed minimal OA changes, arthroscopy findings indicated significant OA changes. Hence radiographic grading is a poor indicator of OA and other diagnostic modality should be sought before proceeding with joint preserving surgery in this highly selected subgroup of dysplastic hips

Background. Labral tears are now recognised as a common pathology especially in young adults. With advancement of arthroscopic techniques, most recent published literature is focused on short- or mid-term results of labral repair or re-fixation. There is limited data regarding long-term results of labral debridement and effect of co-existing pathology on outcomes. We investigated long-term results after arthroscopic labral debridement, the predictors of outcomes and correlation with any co-existing hip pathology. Materials and Methods. Between 1996 and 2003, 50 patients who underwent hip arthroscopy and labral debridement with mean follow-up of 8.4±1.7 years (range 7-13.6 years) were included in our study. Patients' pre-operative Harris Hip Score and co-existing pathologies such as FAI, dysplasia or arthritis were recorded as variables. Further, patients' post-operative HHS and satisfaction at the time of follow-up were recorded as outcomes. Spearman's rho correlation coefficient and regression analysis were calculated between these variables and outcomes. Results. Good or excellent results were noted in 80% of patients. The mean pre-operative HHS was 79.3±8.2 (range 58-86) which was improved to 92.2±12.1 (range 46-100) post-operatively. Patients without co-existing pathology had significantly higher satisfaction and HSS. Arthritis had a significantly negative correlation with post-op HHS (rho= -0.27, P<0.05) and satisfaction (rho= -0.32, P<0.05). Eighty-four percent of patients were satisfied and 16% were dissatisfied. All dissatisfied patients (eight cases) had arthritis; two patients also had FAI that did not have decompression of the lesion since it was not recognised at the time. In regression analysis, arthritis was the strongest independent predictors of post-op HHS and satisfaction. Conclusion. Arthroscopic labral debridement of symptomatic tears without co-existing pathology can result in favorable long-term results. Arthritis is the strongest independent predictors of outcomes

To assess the current literature on suture anchor placement for the purpose of identifying factors that lead to suture anchor perforation and techniques that reduce the likelihood of complications.

Three databases (PubMed, Ovid MEDLINE, EMBASE) were searched, and two reviewers independently screened the resulting literature. Methodological quality of all included papers was assessed using Methodological Index for Non-Randomized Studies criteria and the Cochrane Risk of Bias Assessment tool. Results are presented in a narrative summary fashion using descriptive statistics.

Fourteen studies were included in this review. Four case series (491 patients, 56.6% female, mean age 33.9 years), nine controlled cadaveric/laboratory studies (111 cadaveric hips and 12 sawbones, 42.2% female, mean age 60.0 years), and one randomized controlled trial (37 hips, 55.6% female, mean age 34.2 years) were included. Anterior cortical perforation by suture anchors led to pain and impingement of pelvic neurovascular structures. The anterior acetabular positions (three to four o'clock) had the thinnest bone, smallest rim angles, and highest incidence of articular perforation. Drilling angles from 10° to 20° measured off the coronal plane were acceptable. The mid-anterior (MA) and distal anterolateral (DALA) portals were used successfully, with some studies reporting difficulty placing anchors at anterior locations via the DALA portal. Small-diameter (< 1 .8-mm) suture anchors had a lower in vivo incidence of articular perforation with similar stability and pull-out strength in biomechanical studies.

Suture anchors at anterior acetabular rim positions (3–4 o'clock) should be inserted with caution. Large-diameter (>2.3-mm) suture anchors increase the likelihood of articular perforation without increasing labral stability. Inserting small-diameter (< 1 .8-mm) all-suture suture anchors (ASAs) from 10° to 20° using curved suture anchor drill guides, may increase safe insertion angles from all cutaneous portals. Direct arthroscopic visualization, use of fluoroscopy, distal-proximal insertion, and the use of nitinol wire can help prevent articular violation.

Arthroscopic hip surgery is increasingly common in Australia. Hip arthroscopy is indicated for a range of diagnostic and therapeutic purposes, including labral tears, capsular laxity and femoral-acetabular impingement (FAI). Despite this, previous cohort studies aiming to characterise hip pathology seen on arthroscopic examination are mostly limited to patients with known diagnoses of FAI. Therefore, little is known of the native articular wear patterns encountered in other disease states. Therefore, we aimed to define common osteochondral wear patterns for a cohort of patients managed via hip arthroscopy. We retrospectively analysed intraoperative data for 1127 patients managed via hip arthroscopy between 2008 and 2013, for either therapeutic or diagnostic purposes. Intraoperative data was categorized by location (A-E as defined by Fontana et al. 2016) and chondral damage (0-4 scale as defined by Beck et al. 2005) with respect to both acetabulum and femoral head. Data for 1127 patients were included. Location of acetabular chondral pathology was variable with locations C. 1. and D. 1. representing the most common regions of damage. Labral tears predominated in locations C and D. Femoral chondral pathology was evenly distributed. The degree of femoral chondral injury was predominantly grade 1, whilst acetabular wear was evenly distributed. Large proportions of wear were observed at the peripheral superior and anterior regions of the lunate surface of the acetabulum in keeping with prior works. However, we observed higher rates of central wear and lower rates of grade 4 acetabular damage extending into superior/posterior zones, in our cohort. Our work characterises common articular wear patterns encountered at the time of hip arthroscopy. Further inquiry into the natural history of osteochondral lesions is needed to better understand and manage these conditions

Since its creation, labral repair has become the preferred method among surgeons for the arthroscopic treatment of acetabular labral tears resulting in pain and dysfunction for patients. Labral reconstruction is performed mainly in revision hip arthroscopy but can be used in the primary setting when the labrum cannot be repaired or is calcified. The purpose of this study was to compare the survival between primary labral repair and labral reconstruction with survival defined as no further surgery (revision or total hip replacement). Patients who underwent labral repair or reconstruction between January 2005 and December 2018 in the primary setting were included in the study. Patients were included if they had primary hip arthroscopy with the senior author for femoroacetabular impingement (FAI), involving either labral reconstruction or labral repair, and were within the ages of 18 and 65 at the time of surgery. Exclusion criteria included confounding injuries (Leggs Calves Perthes, avascular necrosis, femoral head fracture, etc.), history of unilateral or bilateral hip surgeries, or Tönnis grades of 2 or 3 at the time of surgery. Labral repairs were performed when adequate tissue was available for repair and labral reconstruction was performed when tissue was absent, ossified or torn beyond repair. A total of 501 labral repairs and 114 labral reconstructions performed in the primary setting were included in the study. Labral reconstruction patients were older (37±10) compared to labral repair (34±11).(p=0.021). Second surgeries were required in 19/114 (17%) of labral reconstruction and 40/501(8%) [odds ratio: 2.3; 95% CI 1.3 to 4.2] (p=0.008). Revision hip arthroscopy were required in 6/114(5%) labral reconstructions and 33/501(6.5%) labral repair (p=0.496). Total hip replacement was required in 13/114 labral reconstructions and 7/501 labral repairs [odds ratio:9.1 95%CI 3.5 to 23] (p=< 0.01). The mean survival for the labral repair group was 10.2 years (95%CI:10 to 10.5) and 11.9 years (98%CI:10.9 to 12.8) in the labral reconstruction group. Conversion to total hip was required more often following primary labral reconstruction. Revision hip arthroscopy rates were similar between groups as was the mean survival, with both over 10 years. Similar survival was seen in labral repair and reconstruction when strict patient selection criteria are followed

Removal of bullets retained within joints is indicated to prevent mechanical blockade, 3rd body wear and resultant arthritis, plus lead arthropathy and systemic lead poisoning. The literature is sparse on this subject, with mostly sporadic case reports utilizing hip arthroscopy. We report on the largest series of removal of bullets from the hip joints using open surgical. We reviewed prospectively collected data of patients who presented to a single institution with civilian gunshot injuries that breached the hip joint between 01 January 2009 and 31 December 2022. We included all cases where the bullet was retained within the hip joint area. Exclusion criteria: cases where the hip joint was not breached, bullets were not retained around the hip area or cases with isolated acetabulum involvement. One hundred and eighteen (118) patients were identified. One patient was excluded as the bullet embedded in the femur neck was sustained 10 years earlier. Of the remaining 117 patients, 70 had retained bullets around the hip joint. In 44 patients we undertook bullet removal using the followingsurgical hip dislocation (n = 18), hip arthrotomy (n = 18), removal at site of fracture fixation/replacement (n = 2), posterior wall osteotomy (n = 1), direct removal without capsulotomy (tractotomy) (n = 5). In 26 patients we did not remove bullets for the following reasons: final location was extra-capsular embedded in the soft tissues (n=17), clinical decision to not remove (n=4), patients’ clinical condition did not allow for further surgery (n= 4) and patient refusal (n=1). No patients underwent hip arthroscopy. With adequate pre-operative imaging and surgical planning, safe surgical removal of retained bullets in the hip joint can be achieved without the use of hip arthroscopy; using the traditional open surgical approaches of arthrotomy, tractotomy and surgical hip dislocation
