Aims. Lumbar disc prolapse is a frequent indication for surgery. The few available long-term follow-up studies focus mainly on repeated surgery for recurrent disease. The aim of this study was to analyze all reasons for additional surgery for patients operated on for a primary lumbar disc prolapse. Methods. We retrieved data from the Swedish spine register about 3,291 patients who underwent primary surgery for a lumbar disc prolapse between January 2007 and December 2008. These patients were followed until December 2020 to record all additional lumbar spine operations and the reason for them. Results. In total, 681 of the 3,291 patients (21%) needed one or more additional operations. More than three additional operations was uncommon (2%; 15/906). Overall, 906 additional operations were identified during the time period, with a mean time to the first of these of 3.7 years (SD 3.6). The most common reason for an additional operation was recurrent disc prolapse (47%; 426/906), followed by spinal stenosis or degenerative spondylolisthesis (19%; 176/906), and segmental pain (16%; 145/906). The most common surgical procedures were revision discectomy (43%; 385/906) and instrumented fusion (22%; 200/906). Degenerative spinal conditions other than disc prolapse became a more common reason for additional surgery with increasing length of follow-up. Most patients achieved the minimally important change (MIC) for the patient-reported outcomes after the index surgery. After the third additional spinal operation, only 20% (5/25) achieved the MIC in terms of leg pain, and 29% (7/24) in terms of the EuroQol five-dimension index questionnaire visual analogue scale. Conclusion. More than one in five patients operated on for a lumbar disc prolapse underwent further surgery during the 13-year follow-up period. Recurrent disc prolapse was the most common reason for additional surgery, followed by spinal stenosis and segmental pain. This study shows that additional operations after primary disc surgery are needed more frequently than previously reported, and that the outcome profoundly deteriorates after the second additional operation. The findings from this study can be used in the shared decision-making process. Cite this article: Bone Joint J 2022;104-B(5):627–632

Aims. Repeated lumbar spine surgery has been associated with inferior clinical outcomes. This study aimed to examine and quantify the impact of this association in a national clinical register cohort. Methods. This is a population-based study from the Norwegian Registry for Spine surgery (NORspine). We included 26,723 consecutive cases operated for lumbar spinal stenosis or lumbar disc herniation from January 2007 to December 2018. The primary outcome was the Oswestry Disability Index (ODI), presented as the proportions reaching a patient-acceptable symptom state (PASS; defined as an ODI raw score ≤ 22) and ODI raw and change scores at 12-month follow-up. Secondary outcomes were the Global Perceived Effect scale, the numerical rating scale for pain, the EuroQoL five-dimensions health questionnaire, occurrence of perioperative complications and wound infections, and working capability. Binary logistic regression analysis was conducted to examine how the number of previous operations influenced the odds of not reaching a PASS. Results. The proportion reaching a PASS decreased from 66.0% (95% confidence interval (CI) 65.4 to 66.7) in cases with no previous operation to 22.0% (95% CI 15.2 to 30.3) in cases with four or more previous operations (p < 0.001). The odds of not reaching a PASS were 2.1 (95% CI 1.9 to 2.2) in cases with one previous operation, 2.6 (95% CI 2.3 to 3.0) in cases with two, 4.4 (95% CI 3.4 to 5.5) in cases with three, and 6.9 (95% CI 4.5 to 10.5) in cases with four or more previous operations. The ODI raw and change scores and the secondary outcomes showed similar trends. Conclusion. We found a dose-response relationship between increasing number of previous operations and inferior outcomes among patients operated for degenerative conditions in the lumbar spine. This information should be considered in the shared decision-making process prior to elective spine surgery. Cite this article: Bone Joint J 2023;105-B(4):422–430

The Royal College of Surgeons of England (RCS) Good Surgical Practice guidance identifies essential criteria for surgical operation note documentation. The current quality improvement project aims to identify if using pre-templated operation notes for documenting fractured neck of femur surgery results in improved documentation when compared to free hand orthopaedic operation notes. A total of fourteen categories were identified from the RCS guidance as required across all the operations identified in this study. All operations for the month of October 2021 were identified and the operation notes analysed. Pre-templated operation notes were compared to free hand operation notes. 97 cases were identified, of which 74 were free hand operation notes and 23 were pre-templated fractured neck of femur operation notes. All fourteen categories were completed in 13 (57%) of the templated operation notes vs 0 (0%) in the free hand operation notes (odds ratio 0.0052, 95% CI 0.0003 to 0.0945, p < 0.001). The median total number of completed categories was significantly higher in the templated op-note group compared to the free hand op-note group (templated median 14, range 12-14, vs. free hand median 11, range 9 to 13, p < 0.001). Logistic regression analysis of operation notes written by Registrars or Consultants identified Registrars as more likely to document the antibiotic prophylaxis given (p = 0.025). Use of pre-templated operation notes results in significantly improved documentation. Adoption of generic pre-templated operation notes to improve surgical documentation should be considered across all operations

Aim. To investigate the impact of waiting for surgical treatment for bone and joint infection (BJI) on patient self-reported quality of life (QoL). Method. Patients presenting to clinic between January 2019 and February 2020 completed the EuroQol EQ-5D-5L questionnaire. Patients were divided into three groups: surgery performed; on the waiting list for surgery; or decision for non-operative management. All patients were followed-up for 2 years. The EQ-index score was calculated and change from presentation to 1-year and 2-year follow-up was compared across the 3 groups. Mortality at final follow-up was measured in all groups. Results. 188 patients were included. Of these, 98 had an operation performed, 50 were on the waiting list for surgery but did not receive an operation and 40 were treated non-operatively. At presentation, all three groups had similar EQ-5D-5L index scores (surgery:0.412 SD0.351; waiting list:0.510 SD0.320; non-operative management: 0.467 SD0.354; p=0.269). There was a significant improvement in QoL in patients who underwent surgery when compared to their pre-operative state (mean increase of EQ-index score +0.241 in the first year (SD0.333, p<0.001) and +0.259 (SD0.294, p<0.001) in the second year. Patients on the waiting list for surgery had a small time-dependent decrease in EQ-index score at 1 year (−0.077, SD0.282, p=0.188) and 2 years (−0.140, SD0.359, p=0.401). Patients treated non-operatively had similar changes in EQ-index scores at 1 year (−0.052, SD0.309, p=0.561) and 2 years (−0.146, SD 0.234, p=0.221). Patients who had surgery had significantly better QoL at 2-years after treatment compared to other groups (mean EQ-index scores: surgery performed 0.671 vs. waiting list 0.431, p<0.001; surgery performed vs. non-operative management 0.348, p<0.001). Mortality in the operated group was 3.1%, which was similar to patients who were on the waiting list for surgery (6.5%, p=0.394) but lower than patients who were non-operatively managed (14.7%, p=0.014). Conclusions. The Covid-19 pandemic created long waiting times for some patients. Selecting patients with BJI who can safely wait for surgery is difficult. QoL for patients with BJI deteriorates over time if surgery is delayed or not performed. When patients decline surgery, they should be counselled that their QoL is likely to be impaired over time. The relationship between waiting time and mortality merits further study

The number of total knee arthroplasties continues to increase annually with over 90,000 total knee replacements performed in the United Kingdom in 2018. Multiple national bodies including the British Association for Surgery of the Knee (BASK) and the British Orthopaedic Association collaborated in July 2019 to produce best practice guidance for knee arthroplasty surgery. This study aims to review practice in a regional healthcare trust against these guidelines. Fifty total knee replacement operation notes were reviewed between January and February 2020 from 11 different consultant orthopaedic surgeons. Documents were assessed against 17 criteria recommended by the BASK guidance. Personnel names and grades were generally well documented. Tourniquet time and pressure were documented in over 98% of operation notes however, protection from spirit burns was not documented at all. Trialling and soft tissue balancing was well recorded in 100% and 96% of operation notes respectively. Areas lacking in documentation included methods utilised to optimise cementation technique and removal of cement debris. Protection of key knee structures was documented in only 56% of operation notes clearly. Prior to closure, final assessment of mechanism integrity, collateral ligament was not documented at all and final ROM after implantation of components was recorded 34% of the time. Subsequently authors have created a universal operation note template, uploaded onto the patient electronic notes, which prompts surgeons to complete documentation of the relevant criteria advocated by BASK. In conclusion, detailed and systematic documentation is vital to prevent adverse events and reduce the risk of litigation. By producing detailed operative templates this risk can be mitigated

Aims. This study explores data quality in operation type and fracture classification recorded as part of a large research study and a national audit with an independent review. Patients and Methods. At 17 centres, an expert surgeon reviewed a randomly selected subset of cases from their centre with regard to fracture classification using the AO system and type of operation performed. Agreement for these variables was then compared with the data collected during conduct of the World Hip Trauma Evaluation (WHiTE) cohort study. Both types of surgery and fracture classification were collapsed to identify the level of detail of reporting that achieved meaningful agreement. In the National Hip Fracture Database (NHFD), the types of operation and fracture classification were explored to identify the proportion of “highly improbable” combinations. Results. The records were reviewed for 903 cases. Agreement for the subtypes of extracapsular fracture was poor; most centres achieved no better than “fair” agreement. When the classification was collapsed to a single option for “extracapsular” fracture, only four centres failed to have at least “moderate” agreement. There was only “moderate” agreement for the subtypes of intracapsular fracture, which improved to “substantial” when collapsed to “intracapsular”. Subtrochanteric fracture types were well reported with “substantial” agreement. There was near “perfect” agreement for internal fixation procedures. “Perfect” or “substantial” agreement was achieved when the type of arthroplasty surgery was reported at the level of “hemiarthroplasty” and “total hip replacement”. When reviewing data submitted to the NHFD, a minimum of 5.2% of cases contained “highly improbable” procedures for the stated fracture classification. Conclusion. The complexity of collecting fracture classification data at a national scale compromises the accuracy with which detailed classification systems can be reported. Data around type of surgery performed show similar tendencies. Data capture, reporting, and interpretation in future studies must take this into account.

Aims. This study aimed to compare mortality in trochanteric AO/OTA A1 and A2 fractures treated with an intramedullary nail (IMN) or sliding hip screw (SHS). The primary endpoint was 30-day mortality, with secondary endpoints at 0 to 1, 2 to 7, 8 to 30, 90, and 365 days. Methods. We analyzed data from 26,393 patients with trochanteric AO/OTA A1 and A2 fractures treated with IMNs (n = 9,095) or SHSs (n = 17,298) in the Norwegian Hip Fracture Register (January 2008 to December 2020). Exclusions were made for patients aged < 60 years, pathological fractures, pre-2008 operations, contralateral hip fractures, fractures other than trochanteric A1/A2, and treatments other than IMNs or SHSs. Kaplan-Meier and Cox regression analyses adjusted for type of fracture, age, sex, cognitive impairment, American Society of Anesthesiologists (ASA) grade, and time period were conducted, along with calculations for number needed to harm (NNH). Results. In unadjusted analyses, there was no significant difference between IMN and SHS patient survival at 30 days (91.8% vs 91.1%; p = 0.083) or 90 days (85.4% vs 84.5%; p = 0.065), but higher one-year survival for IMNs (74.5% vs 73.3%; p = 0.031) compared with SHSs. After adjustments, no significant difference in 30-day mortality was found (hazard rate ratio (HRR) 0.94 (95% confidence interval (CI) 0.86 to 1.02(; p = 0.146). IMNs exhibited higher mortality at 0 to 1 days (HRR 1.63 (95% CI 1.13 to 2.34); p = 0.009) compared with SHSs, with a NNH of 556, but lower mortality at 8 to 30 days (HRR 0.89 (95% CI 0.80 to 1.00); p = 0.043). No differences were observed in mortality at 2 to 7 days (HRR 0.94 (95% CI 0.79 to 1.11); p = 0.434), 90 days (HRR 0.95 (95% CI 0.89 to 1.02); p = 0.177), or 365 days (HRR 0.97 (95% CI 0.92 to 1.02); p = 0.192). Conclusion. This study found no difference in 30-day mortality between IMNs and SHSs. However, IMNs were associated with a higher mortality at 0 to 1 days and a marginally lower mortality at 8 to 30 days compared with SHSs. The observed differences in mortality were small and should probably not guide choice of treatment. Cite this article: Bone Joint J 2024;106-B(6):603–612

Introduction:. Unicompartmental knee arthroplasty (UKA) is becoming an increasingly popular option in single compartment osteoarthritis. As a result, diverse second operations including revisions to total knee arthroplasty (TKA) will also increase. The objective of this study is to investigate the distribution of causes of second operations after UKA. Methods:. We retrospectively reviewed 695 UKAs performed on 597 patients between January 2003 and December 2011. Except in one case, all UKAs were replaced at the medial compartment of the knee. The UKAs were performed on 559 (80.4%) women's knees and 136 (19.6%) men's knees. The mean age at the time of UKA was 61.5 years. The mobile-bearing designs were those that were predominantly implanted (n = 628 mobile, 90.2%; n = 67 fixed). The mean interval between UKA and second operation was 14.1 months. Results:. In our study, the burden of a second operation after the initial UKA was 7.3%, and the total number of second operations was 51 (n = 45 mobile, n = 6 fixed). The most common cause of a second operation after a mobile-bearing UKA was the dislocation of the meniscal bearing (34.8%), followed by component loosening (21.7%), the formation of a cement loose body (15.2%), unexplained pain (13%), infection (6.5%), periprosthetic fracture (4.3%), and others (4.4%). For the fixed-bearing UKA, the causes of a second operation were loosening (n = 2), unexplained pain (n = 2), and bearing wear (n = 1). The main causes of either a revision UKA or a conversion to TKA were multiform operations that included bricement, internal fixation for a periprosthetic fracture, isolated bearing changes, open debridement with bearing changes, or implant removal due to early infection. Conversions to TKA during the second operation were performed in 17 cases. Discussion and conclusion:. The most common cause of a second operation after a mobile-bearing UKA was the dislocation of the bearing, followed by component loosening and the formation of a cement loose body. After a fixed-bearing UKA, component loosening and unexplained pain were the most common. A cause-based approach to the primary and failed UKA may be helpful to minimize the possibility of a second operation and to give rise to a successful outcome of a revision TKA

Introduction: Since 2004 we chose the arthroscopic method of therapy by the retrocalcaneal bursitis and problems caused by prominence of heel Haglund type. Materials and Method: We operated 48 patients (52 heel bones) by arthroscopic method. We do this operation on ventral position with using 2 or 3 paraachilear incisions, we commonly check the progress of the operation using X-rays sciascopy. After operation we recommend light exercises of the movement of the ankle and 3 week walking on crutches with limited weight. Antitrombotic prophylaxis is standard. Results: We checked the results after 2–48 months after operating procedure. The patients were examined clinically and with the help of VAS (Visual Analogue Scale). The condition of all patients has improved, most of them were very satisfied with the operation. We have not noticed any disorders in healing operation wounds, 1 deep trombosis has been diagnosed by the sonography. We compared this arthroscopy method with open operating method. We have been using since the year 2004 both operating methods, but we have been trying to separate the indications for the arthroscopy and for the open approach, because we are the meaning, that the arthroscopy technique is not the best choice in all cases. We have recently set clear indications for both methods in our orthopaedic department. The progress of rehabilitation was noticeably faster than by the open method, postoperative swelling and pain were markedly less as well

1. The operation of spinal fusion combined with Harrington rod instrumentation is often accompanied by severe blood loss. Factors affecting the degree of blood loss are discussed with emphasis on the adverse effects of partial or complete obstruction of the inferior vena cava during operation. 2. A new scoliosis operating frame is described which is designed to encourage normal venous return during spinal fusion with the patient prone. In addition, it stabilises the patient during the procedure. 3. A standard anaesthetic technique and method of supporting the patient have been used in forty major corrective operations in thirty-eight consecutive cases of scoliosis in the past nine months. The measured blood loss at operation encountered in this series compares favourably with the quantities lost in a previously reported series of cases in which alternative methods of anaesthesia and of support for the patients were used. 4. All operations in both series were performed by the same surgeon (J. E. H.). Although further experience with the surgical technique has helped in reducing the blood loss in the later series, the same basic method of exposure and performance of the instrumentation and fusion has been used in all cases

Objectives

To report the five-year results of a randomised controlled trial examining the effectiveness of arthroscopic acromioplasty in the treatment of stage II shoulder impingement syndrome.

Studies of operation notes have shown they can vary in quality and affect patient safety. This audit compares the quality of operation notes against standards set by the Royal College of Surgeons of England and the British Orthopaedic Association. Information from operation notes was collected prospectively over a two-week period. All operations performed were included and trainees from the region coordinated data collection in 9 hospitals. Data from 1091 operation notes was reviewed. A number of standards were nearly met including legibility (98.4%), the name of operating surgeon (99.3%) and operation title (99.1%). However a number of standards were not met and those with potential patient safety implications include availability on the ward (88.8%), documentation of type of anaesthetic used (78.6%), diagnosis (73.4%) and findings (80.1%). In addition, the postoperative instructions recorded the need for and type of postoperative antibiotics or venous thromboembolism prophylaxis in only 49.7% and 48.8% of cases respectively. The quality of operation notes studied across the region in this period was variable. Software programmes meant some hospitals had better results for date, time and patient identification details. Following this study, awareness of the standards combined with additional local measures may improve the quality of operation notes

Metal-on-metal (MoM) hip resurfacing was developed in the 1990s by surgeons in Birmingham, UK, as a surgical solution to the problem of osteoarthritis in younger, more active patients. Early results were promising and the procedure gained in popularity. However, adverse reports of soft-tissue reaction and failure started to appear from 2008 onwards. Surgeons may be asked to write medico-legal reports on the surgical aspects of an individual case for claimant lawyers or in defence for the NHSLA or indemnity insurers. The purpose of this article is to cover some of the aspects of the operation that may be considered in such medico-legal reports

Infection of the intervertebral space is a rare complication of operation on the disc (Ford and Key 1955). It occurred in five cases in a series of 650 operations for lumbar disc protrusion done by two of the authors of this paper--an incidence of 0-8%. Symptoms began between seven and twelve days after operation. After initial relief of the original sciatic pain, the patients developed severe back pain and muscle cramps in the legs. Straight-leg raising became much more limited than before operation. The erythrocyte sedimentation rate was raised in all cases. The diagnosis was confirmed by rescreening the Myodil, when an indentation was seen opposite the intervertebral space from which the disc had been excised. Early removal of infected material from the disc space resulted in complete relief of pain and cure of the infection

British military forces are heavily committed in Iraq and Afghanistan. Operation HERRICK, currently supported by a Role 2(Enhanced) medical facility at Camp Bastion, is predicted to continue for the next 10 years. There has been no large published series on surgical workload on Operation HERRICK. The aim of this study is to determine and plan future medical needs. A retrospective analysis of operating theatre records between 10th October 2006 and 31st Oct 2007 was performed. Data was collated on a monthly basis, to assess seasonal variation, and included patient demographics, operation type and time of operation. During the study period 968 cases required 1262 procedures. Thirty-four per cent were ISAF, 27% were Afghan soldiers, police or enemy forces and 39% were civilians, of which, 43% were children. Ninety-one per cent were secondary to battle injury and 50% were emergencies. The breakdown of procedures, by specialty, was 67% (841) were orthopaedic, 16% (199) general surgery, 8% (96) head and neck, 5% (55) burns surgery and a further 4% (50) were non-battle, non-emergency procedures. During the second half of the study period 655 cases were operated on compared to 313 in the preceding half (p< 0.05). Twenty-eight per cent of cases were performed between 6pm and 8am. Surgical workload remains consistently high throughout the study period, however there was significant seasonal variation with casualty rates being greater in the summer months, this may have bearing on the decision to deploy additional surgeons and trainees in the future

Introduction: Hypothesis:- Posterior lumbar interbody fusion (PLIF) produces improvement in the MOS Short Form 36 (SF36) scores comparable to that seen in total hip replacement. Current consensus holds the surgical treatment of lower back pain as less effective or predictable than interventions performed in most other orthopaedic subspecialties. Detailed clinical and economic outcome studies are vital to justify its use in routine practice. This prospective study presents medium to long-term clinical outcome scores for PLIF which are compared with those of an operation that might be considered a modern orthopaedic gold-standard: total hip arthroplasty. Methods: The authors present 100 consecutive PLIF operations performed by the senior author between 1997 and 2004. SF36, Oswestry Disability Index (ODI), Visual Analogue Scores (VAS) and walking distances were prospectively collected and analysed in the post-operative period. Results were compared to the SF36 healthy population norms and with the outcome scores of standard total hip replacement available in the literature. Results: The mean pre-operative ODI was 49. 12 months following surgery this improved to 22. All outcomes as measured by SF36 improved following surgery. The VAS for back pain improved from 8.5 pre-operatively to 3.21 post-operatively. Leg pain improved from 6.98 to 2.85. Improvements in the SF36 scores were similar to those seen in hip arthroplasty. Discussion: The hypothesis has been proven. The gains in function following spinal fusion are comparable with those seen in hip arthroplasty. In the authors’ opinion PLIF is an effective procedure in an appropriately selected patient population

1. In congenital absence of the fibula, the fibrous strip that replaces the bone, abnormal insertions of fibular muscles, and disturbances in the formation and growth of the tarsal bones all go to cause the valgus deformity of the foot and the complete or partial dislocation of the talo-tibial joint. 2. Conservative treatment is justified only for children less than a year old and then only as preparation for operation. 3. Between the second and seventh year of life operations upon the soft tissues are indicated, to eliminate the contractures occurring on the posterior and lateral sides, to restore the proper position of the foot in line with the axis of the tibia, and to restore the normal shape of the foot and muscular equilibrium. At the same time favourable conditions are created for operative reconstruction of the lateral malleolus. 4. Arthrodesis of the talo-tibial joint or reconstruction of the lateral malleolus by a bone graft with the aim of stabilising the foot in the axis of tibia is not advisable in the growing limb. 5. The results obtained in three cases described support the conclusion that the bifurcation operation recommended by Gruca produces a new lateral malleolus with an epiphysis that grows at the same rate as the remainder of the lower epiphysis of the tibia, does not affect the rate of growth of the tibial epiphysis, prevents the recurrence of the deformity, and preserves the mobility of the talo-tibial joint. 6. In early cases this reconstructive operation may be done at the same time as soft-tissue deformities are corrected and subluxation reduced. 7. It is probable that the bifurcation operation should be done on children aged between two and seven years in order to give the limb the best chance to develop normally

The records of 110 cases of ulnar neuritis in 100 patients have been reviewed an average of 4.4 years after anterior transposition, or release of the aponeurosis. Seventy of the patients were reviewed personally. In over half the cases no precipitating cause was apparent. At operation the nerve was constricted by the flexor carpi ulnaris aponeurosis in fifty cases but in twenty-five no abnormal pathology was found. Recovery was greatest when operation was performed within three months of the onset of symptoms. In those cases where no abnormality was found, and those in which adhesions in the postcondylar groove involved the nerve, simple release was less effective than anterior transposition. It is therefore recommended that release be restricted to patients with a short history and with an obvious aponeurotic constriction unaccompanied by adhesions. Anterior transposition is the operation of choice where no abnormality is seen or where the nerve is dislocated, compressed or tethered proximal to the aponeurosis of flexor carpi ulnaris

Dual mobility hip arthroplasty utilizes a freely rotating polyethylene liner to protect against dislocation. As liner motion has not been confirmed in vivo, we investigated the liner kinematics in vivo using dynamic radiostereometry.

16 patients with Anatomical Dual Mobility acetabular components were included. Markers were implanted in the liners using a drill guide. Static RSA recordings and patient reported outcome measures were obtained at post-op and 1-year follow-up. Dynamic RSA recordings were obtained at 1-year follow-up during a passive hip movement: abduction/external rotation, adduction/internal rotation (modified FABER-FADIR), to end-range and at 45° hip flexion. Liner- and neck movements were described as anteversion, inclination and rotation.

Liner movement during modified FABER-FADIR was detected in 12 of 16 patients. Median (range) absolute liner movements were: anteversion 10° (5–20), inclination 6° (2–12), and rotation 11° (5–48) relative to the cup. Median absolute changes in the resulting liner/neck angle (small articulation) was 28° (12–46) and liner/cup angle (larger articulation) was 6° (4–21). Static RSA showed changes in median (range) liner anteversion from 7° (-12–23) postoperatively to 10° (-3–16) at 1-year follow-up and inclination from 42 (35–66) postoperatively to 59 (46–80) at 1-year follow-up. Liner/neck contact was associated with high initial liner anteversion (p=0.01).

The polyethylene liner moves over time. One year after surgery the liner can move with or without liner/neck contact. The majority of movement is in the smaller articulation between head and liner.

A prospective trial has been carried out to determine the value of suction drainage in the operation of meniscectomy. One hundred operations were analysed, in half of which drains had been used. The use of the drain could not be shown to result in any sustained advantages. The demand for analgesics after the operation was reduced but not to a statistically significant level. The size of the early effusion was significantly reduced, but this benefit was lost when the knee was mobilised. The return of power to the quadriceps and of movement to the knee were not hastened. The average volume of fluid drained was 134 millilitres and it has been shown that forty-eight hours is a suitable time for removal of the drain. The use of suction drainage is not advocated for the uncomplicated operation of meniscectomy
