Purpose
This brief historical note describes an arthroscopic instrument presented in Italy in 1950, and still preserved to this day at the library of the Rizzoli Orthopedic Institute in Bologna, ...Italy.
Material and methods
A research on Casuccio, Santacroce, and Banfo prolific scientific collaboration was performed.
Results
The arthroscopic instrument was designed and utilized at the Orthopedic Clinic of the University of Bari, directed by Professor Casuccio, in collaboration with his assistant, Antonio Santacroce, and Giorgio Banfo, an orthopedist, entrepreneur, and owner of a modern establishment dedicated to the production of orthopaedic products and medical instruments.
Conclusion
Much like America and Japan, 1950s Italy offered avant-garde arthroscopic instruments, which resulted from a masterful collaboration of research and development.

BACKGROUND:Recent advances in diagnosis and instrumentation have facilitated the arthroscopic treatment of hip pathology. However, little has been reported on trends in the utilization of hip ...arthroscopy. The purpose of this study was to examine changes in the use of hip arthroscopy as reflected in the American Board of Orthopaedic Surgery (ABOS) database. We also surveyed directors of both sports and joint reconstruction fellowships to determine attitudes toward hip arthroscopy training.
METHODS:The number of hip arthroscopy cases in the ABOS database during 1999 through 2009 was determined. A survey was devised to determine the type of hip arthroscopy training that was currently being offered at the fellowship level.
RESULTS:The number of hip arthroscopy procedures performed by ABOS candidates increased significantly from 0.02 cases per candidate in 1999 to 0.36 cases per candidate in 2009 (p < 0.0001). From 2003 through 2009, a significantly greater percentage of ABOS candidates with sports fellowship training (10.4%) than candidates without such training (2.9%) performed hip arthroscopy (p < 0.0001). During this same time period, candidates in the Northeast and Northwest performed the most hip arthroscopy procedures as a percentage of total procedures (p < 0.0001). Nearly half of the sports and joint reconstruction fellowships that included hip arthroscopy as a component of the training in 2010 had added it within the past three years. Fellows performed fewer than twenty hip arthroscopy cases per year in the majority of training programs.
CONCLUSIONS:The number of hip arthroscopy procedures performed by candidates taking Part II of the ABOS examination increased eighteenfold between 1999 and 2009. This increase is likely the result of several factors, including an increase in the number of programs offering training in hip arthroscopy.
Background:
Hip arthroscopy has traditionally been performed with a perineal post, resulting in various groin-related complications, including pudendal nerve neurapraxias, vaginal tears, and scrotal ...necrosis.
Purpose:
To assess the safety of a technique for hip distraction without the use of a perineal post.
Study Design:
Case series; Level of evidence, 4.
Methods:
We prospectively analyzed a consecutive cohort of 1000 hips presenting to a dedicated hip preservation clinic; all patients had hip pain and were subsequently treated with hip arthroscopy. Demographic variables, hip pathology, and lateral center edge angle were recorded for each case. In the operating room, the patient’s feet were placed in traction boots in a specifically designed distraction setup, and the operative table was placed in varying degrees of Trendelenburg. With this technique, enough resistance is created by gravity and friction between the patient’s body and the bed to allow for successful hip distraction without the need for a perineal post. In a subset of 309 hips (n = 281 patients), the degrees of Trendelenburg as well as the distraction force were analyzed.
Results:
The mean ± SD Trendelenburg angle used among the subset of 309 hips was 11° ± 2°. The mean initial distraction force necessary was 90 ± 28 lb, which decreased to 65 ± 24 lb by 30 minutes after traction initiation (P < .0001). The most important variables in determining initial force for this cohort of patients were, in order of magnitude, sex (P < .0001), weight (P < .0001), and lateral center edge angle (P < .01). No groin-related complications occurred among the entire cohort of patients, including soft tissue or nerve-related complications. The rate of deep venous thrombosis was 2 in 1000.
Conclusion:
The use of the Trendelenburg position and a specially designed distraction setup during hip arthroscopy allows for safe hip distraction without a perineal post, thereby eliminating groin-related soft tissue and nerve complications. Certain patient variables can be used to estimate the required distraction force and inclination angle with this method.
Background:
Tears of the superior labrum (superior labrum anterior and posterior SLAP lesions) of the shoulder are uncommon injuries; however, the incidence of surgical correction seems to be ...increasing.
Purpose:
To report the findings of a review of a proprietary descriptive database that catalogs cases for the purpose of board certification on the demographics of SLAP lesion repair. It is the authors’ impression that the percentage of cases of SLAP lesion repairs reported by young orthopaedic surgeons is high and that complications associated with this are not insignificant.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
We searched the American Board of Orthopedic Surgery (ABOS) Part II database to evaluate changes in treatment over time and to identify available outcomes and associated complications of arthroscopic repair of SLAP lesions. The database was searched for all SLAP lesions (ICD-9 code 840.7) and SLAP repairs (CPT code 29807) for the years 2003 through 2008. Utilization was analyzed by geographic region and was also obtained based on applicant subspecialty declaration.
Results:
There were 4975 SLAP repairs, representing 9.4% of all applicants’ shoulder cases. Mean follow-up was 8.9 weeks because of the time-limited case collection period. There were 78.4% who were men, and 21.6% of patients were women. The percentage of shoulder cases that were SLAP repairs increased over the study period from 9.4% to 10.1% by 2008 (P = .0163). Mean age of male patients was 36.4 ± 13.0 years, with a maximum of 85 years. Mean age of female patients was 40.9 ± 14.0 years, with a maximum of 88 years. Pain was reported as absent in only 26.3% of patients at follow-up and function as normal in only 13.1%. There were 40.1% of applicants who self-reported their patients to have an excellent result. The self-reported complication rate was 4.4%. Declared sports medicine specialists had a higher percentage of SLAP repairs than did general orthopaedic surgeons: 12.4% versus 9.2%.
Conclusion:
The percentage of shoulder cases that are SLAP repairs reported by the candidates is 3 times the published incidence supported by the current literature. The large number of repairs in middle-aged and elderly patients is concerning. Focusing on educating young orthopaedic surgeons to appropriately recognize and treat symptomatic SLAP lesions may bring the rate of SLAP repairs down.
Purpose The purpose of this systematic review was to evaluate the literature to determine complications of hip arthroscopy, with a secondary focus on how to minimize complications and risks. Methods ...Two independent reviewers performed a search of PubMed for articles that contained at least 1 of the following terms: complications and hip arthroscopy, hip impingement, femoral acetabular impingement and complications, or femoroacetabular impingement (FAI) and complications. The search was limited to articles published between 1999 and June 2013. An additional search was performed for articles evaluating techniques on how to minimize complications. Results We identified 81 studies (5,535 patients; 6,277 hips). The mean age was 35.48 years, and the mean body mass index was 25.20 kg/m2 . Of the participants, 52% were male and 48% were female. The majority of studies were Level IV Evidence (63%). A total of 285 complications were reported, for an overall rate of 4.5%. There were 26 major complications (0.41%) and a 4.1% minor complication rate. The overall reoperation rate was 4.03%. A total of 94 hips underwent revision arthroscopy. Regarding open procedures, 150 patients (93%) underwent either total hip arthroplasty or a hip resurfacing procedure. The conversion rate to total hip arthroplasty or a resurfacing procedure was 2.4%. Conclusions Overall, primary hip arthroscopy is a successful procedure with low rates of major (0.41%) and minor (4.1%) complications. The reoperation rate was 4.03% in our review. There is admittedly a learning curve to performing hip arthroscopy, and we present a systematic review of the complications and how to minimize these complications with careful technique and planning. Level of Evidence Level IV, systematic review of Level II to V studies.
Introduction
Arthroscopic superior capsule reconstruction (ASCR) using fascia lata autograft is a new surgical technique developed to overcome irreparable rotator cuff tears. There is little ...information about graft tear after ASCR and its impact on clinical outcome. This study is to investigate the graft tear rate, pattern of failure, and its correlation with clinical outcomes after arthroscopic superior capsule reconstruction (ASCR).
Materials and methods
From June 2013 to June 2016, 31 shoulders in 31 consecutive patients (mean 65.3 years) underwent ASCR using fascia lata autograft for irreparable large-to-massive tears. Magnetic resonance imaging (MRI) was performed before surgery and at mean 12.8 months (12–24 months) after surgery to assess fatty infiltration progression and graft integrity. Graft tear was defined as the loss of graft continuity and was categorized as medial and lateral rows according to the failure location. Acromiohumeral distance (AHD) was pre- and postoperatively measured with the standard radiograph. Pain visual analog scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, constant score, and physical examination were used to assess clinical outcomes. Average follow-up was 15 months (range 12–24 months) after surgery.
Results
Mean active forward elevation increased from 133° to 146° (
P
= 0.011). Mean VAS score, ASES score, and constant score significantly improved: from 6 to 2.5, 54.4 to 73.7, and 51.7 to 63.7, respectively (
P
< 0.001). There was no remarkable progression of fatty infiltration after surgery. AHD increased from 5.3 mm preoperatively to 6.4 mm postoperatively (
P
< 0.016). Nine patients (29%) showed graft tear on follow-up MRI: 7 and 2 at the medial and lateral rows, respectively. Although the intact graft group showed better outcomes than the graft tear group (pain VAS score 2.3 vs. 3.0; ASES score 74.1 vs. 69.8; constant score 63.4 vs. 57.9), the results were not statistically significant.
Conclusions
Graft tear rate after ASCR assessed by MRI was 29%, and failures mostly occurred at the medial row. The graft tear group showed clinical improvement despite the recurred superior capsule defect.
Level of evidence
IV, case series, treatment study.
Background:
Limited evidence exists concerning the effect of age on hip arthroscopy outcomes for femoroacetabular impingement (FAI).
Purpose/Hypothesis:
The purpose was to investigate ...patient-reported outcomes (PROs) and clinical failure rates across various age groups in patients undergoing hip arthroscopy for FAI. We hypothesized that older patients would experience lower improvements in PROs and higher clinical failure rates.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
A total of 109 of 130 eligible consecutive patients underwent hip arthroscopy for FAI with a minimum 5-year follow-up. Patients were stratified into 3 groups for comparison (ages 15-34, 35-50, and 51-75 years). Clinical survival rates to revision surgery or total hip arthroplasty (THA) were determined by Kaplan-Meier analysis, and PROs were assessed using analysis of variance. Regression analysis was used to determine factors associated with clinical failure and ΔPROs from baseline to 5 years.
Results:
The 5-year survival-to-revision rate was 71% (survival time, 69.2 months; 95% CI, 62.8 to 75.5 months). A significant difference in survival to THA was found between groups (P = .030). Being in the older group versus the young and middle-aged groups predicted increased risk of THA conversion (hazard ratio, 5.7; 95% CI, 1.1 to 28.6; P = .035). Overall modified Harris Hip Score (mHHS) and Nonarthritic Hip Score (NAHS) improved from baseline to 5 years (mHHS, P < .001; NAHS, P < .001). Body mass index (mHHS: beta, −1.2; 95% CI, −2.2 to −0.3; P = .013; NAHS: beta, −1.6; 95% CI, −2.6 to −0.5; P = .005) and baseline PROs (mHHS: beta, −0.8; 95% CI, −1.1 to −0.4; P < .001; NAHS: beta, −0.7; 95% CI, −1.1 to −0.4; P < .001) were predictive of 5-year ΔPROs. A decrease was seen in minimal clinically important difference rates in middle-aged (P = .011) and old (P = .030) groups from 6-month to 5-year outcomes.
Conclusion:
Although hip arthroscopy for FAI yielded improvements in PROs regardless of age, middle-aged and older patients experienced greater declines in clinical outcomes over time than younger patients. Older patients remain good candidates for arthroscopy despite a greater risk for conversion to THA.
What is known and objective
Postoperative pain relief is a critical issue for hip arthroscopy surgery (HAS). This study aimed to investigate the effect of preemptive non‐steroidal anti‐inflammatory ...drugs (NSAIDs) for postoperative analgesia in femoroacetabular impingement (FAI) patients receiving HAS.
Methods
This multicenter, randomized, controlled study enrolled 204 FAI patients receiving HAS, then assigned them to preoperative (PRE, N = 103) or postoperative (POS, N = 101) group as a 1:1 ratio; the PRE group administrated NSAIDs from 24 h pre‐surgery to day 7 (D7) post‐surgery, while the POS group administrated NSAIDs from 12 h post‐surgery to D7 post‐surgery.
Results and discussion
Pain at rest was reduced at D1 (p = 0.016) and D2 (p = 0.023); pain at movement was decreased at D1 (p = 0.002), D2 (p = 0.020), and D3 (p = 0.030) in the PRE group compared with POS group, but not at other time points (all p > 0.05). Patient's satisfaction was increased at D1 (p = 0.013) and D3 (p = 0.029) in the PRE group compared to the POS group, but not at D7 (p = 0.145). Pethidine was less consumed at D3 (p = 0.038) and D7 (p = 0.017) in the PRE group in contrast with the POS group. Harris hip scores were similar at D7 (p = 0.124), month 1 (M1) (p = 0.273), and M3 (p = 0.360) between groups. Adverse events incidence was similar between groups (all p > 0.05). Besides, subgroup analysis discovered that pain was not influenced by the types of NSAID in both groups (all p > 0.05).
What is new and conclusion
Starting NSAIDs before HAS provides better short‐term pain relief and improves patient's satisfaction compared with its postoperative utilization, while does not induce additional adverse events in FAI patients.
This study aimed to investigate the effect of pre‐emptive non‐steroidal anti‐inflammatory drugs (NSAIDs) for postoperative analgesia in femoroacetabular impingement (FAI) patients receiving hip arthroscopy surgery (HAS). Totally, 204 FAI patients were enrolled, then randomly assigned to preoperative (PRE, N = 103) or postoperative (POS, N = 101) groups as a 1:1 ratio; the PRE group administrated NSAIDs from 24 h pre‐surgery to day 7 (D7) post‐surgery, while the POS group administrated NSAIDs from 12 h post‐surgery to D7 post‐surgery. Compared to POS group, pain at rest was reduced at D1 and D2; pain at movement was decreased at D1, D2, and D3; patient's satisfaction was increased at D1 and D3; pethidine was less consumed at D3 and D7 in the PRE group. Harris hip scores and adverse events incidence were similar between groups. Conclusively, starting NSAIDs before HAS provides better short‐term pain relief and improves patient's satisfaction compared with its postoperative utilization, while does not induce additional adverse events in FAI patients.
Temporomandibular joint (TMJ) arthroscopy, a diagnostic and therapeutic procedure involving the introduction of a small-calibre optical scope into the joint compartments for the treatment of internal ...derangement, has been gaining prominence and is now being recommended as the first therapeutic option due to the good results obtained and minimal invasiveness. However, the technical difficulty, high cost, need for specific instruments, and video tower system remain limiting factors for the implementation of TMJ arthroscopy by practicing professionals. The objective of this study was to examine the possibility of using a smartphone optical adaptation platform in TMJ arthroscopy. Ten qualified examiners with different levels of expertise in TMJ arthroscopy located four points of interest in the upper TMJ compartment of a validated realistic simulator and assessed the resolution of the images obtained and ergonomics of the smartphone platform for each point of interest, assigning a score of 0–2 (0 = poor, 1 = intermediate, and 2 = good performance in comparison to the video tower). For image quality, 77.5% of scores were ‘good’, while 22.5% were ‘intermediate’. For ergonomics, 62.5% of scores were ‘good’ and 37.5% were ‘intermediate’. In conclusion, the platform appears to be safe for TMJ arthroscopy in humans.
Background:
Glenoid bone loss is a common finding in association with anterior shoulder instability. This loss has been identified as a predictor of failure after operative stabilization procedures. ...Historically, 20% to 25% has been accepted as the “critical” cutoff where glenoid bone loss should be addressed in a primary procedure. Few data are available, however, on lesser, “subcritical” amounts of bone loss (below the 20%-25% range) on functional outcomes and failure rates after primary arthroscopic stabilization for shoulder instability.
Purpose:
To evaluate the effect of glenoid bone loss, especially in subcritical bone loss (below the 20%-25% range), on outcomes assessments and redislocation rates after an isolated arthroscopic Bankart repair for anterior shoulder instability.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
Subjects were 72 consecutive anterior instability patients (73 shoulders) who underwent isolated anterior arthroscopic labral repair at a single military institution by 1 of 3 sports medicine fellowship-trained orthopaedic surgeons. Data were collected on demographics, the Western Ontario Shoulder Instability (WOSI) score, Single Assessment Numeric Evaluation (SANE) score, and failure rates. Failure was defined as recurrent dislocation. Glenoid bone loss was calculated via a standardized technique on preoperative imaging. The average bone loss across the group was calculated, and patients were divided into quartiles based on the percentage of glenoid bone loss. Outcomes were analyzed for the entire cohort, between the quartiles, and within each quartile. Outcomes were then further stratified between those sustaining a recurrence versus those who remained stable.
Results:
The mean age at surgery was 26.3 years (range, 20-42 years), and the mean follow-up was 48.3 months (range, 23-58 months). The cohort was divided into quartiles based on bone loss. Quartile 1 (n = 18) had a mean bone loss of 2.8% (range, 0%-7.1%), quartile 2 (n = 19) had 10.4% (range, 7.3%-13.5%), quartile 3 (n = 18) had 16.1% (range, 13.5%-19.8%), and quartile 4 (n = 18) had 24.5% (range, 20.0%-35.5%). The overall mean WOSI score was 756.8 (range, 0-2097). The mean WOSI score correlated with SANE scores and worsened as bone loss increased in each quartile. There were significant differences (P < .05) between quartile 1 (mean WOSI/SANE, 383.3/62.1) and quartile 2 (mean, 594.0/65.2), between quartile 2 and quartile 3 (mean, 839.5/52.0), and between quartile 3 and quartile 4 (mean, 1187.6/46.1). Additionally, between quartiles 2 and 3 (bone loss, 13.5%), the WOSI score increased to rates consistent with a poor clinical outcome. There was an overall failure rate of 12.3%. The percentage of glenoid bone loss was significantly higher among those repairs that failed versus those that remained stable (24.7% vs 12.8%, P < .01). There was no significant difference in failure rate between quartiles 1, 2, and 3, but there was a significant increase in failure (P < .05) between quartiles 1, 2, and 3 (7.3%) when compared with quartile 4 (27.8%). Notably, even when only those patients who did not sustain a recurrent dislocation were compared, bone loss was predictive of outcome as assessed by the WOSI score, with each quartile’s increasing bone loss predictive of a worse functional outcome.
Conclusion:
While critical bone loss has yet to be defined for arthroscopic Bankart reconstruction, our data indicate that “critical” bone loss should be lower than the 20% to 25% threshold often cited. In our population with a high level of mandatory activity, bone loss above 13.5% led to a clinically significant decrease in WOSI scores consistent with an unacceptable outcome, even in patients who did not sustain a recurrence of their instability.
