Background

Recent meta-analyses have shown reduced re-rupture rates for the surgical management of Achilles ruptures. However percutaneous repair has been demonstrated to lead to improved function, patient satisfaction but greater complications than open repair. In the current economic climate, we believe it is reasonable to consider the financial cost of rupture management for both the patient and the provider. We aimed to determine the cost effectiveness of operative treatment of ruptures of the Achilles tendon based upon theatre occupancy, clinic attendance and cast changes, operative complications and functional assessment score.

Methods

We audited the cost effectiveness of the surgical management of Achilles tendon ruptures between 2005–2011 in our unit by comparing 49 patients receiving percutaneous repair to 35 patients whom had open repairs (Retrospective cohort study level 3).

The percutanous repair of the Achilles tendon is a cost efficient method of restoring early limb function and may offer reduced risk of re-rupture and wound infection. This technique has been described in the elderly population and elite athletes; we present an evaluation of this technique in a District General Hospital setting. We have prospectively audited the outcome of 56 patients who have elected to have percutaneous repair for Achilles tendon rupture from 2009–2011. The majority were males (44) with mean age of 46 years (range 27–80). Twenty nine patients ruptured the right tendon and 27 the left. 82% (46) of injuries were sustained whilst exercising: e.g. football (22), badminton (7), running (5). All but 2 patients were managed on a Day Case basis and 4 requested general anaesthesia. Patients were immediately weight bearing in a brace following surgery and commenced physiotherapy at 2 weeks.

Functional outcome was measured using a modified Achilles Tendon Rupture Score (ATRS) at 3, 6, 9 and 12 months: 100 score equals maximal limitation. The mean ATRS scores a 3, 6, 9 and 12 months were 53 (7–82), 31 (0–74), 30 (0–67) and 15 (1–52) respectively. We have had 4 complications: 2 sural nerve injuries, 1 poor wound healing and 1 re-rupture at 8 weeks.

Overall complication rate was 7.1%, comparable to other studies. We have shown a good outcome following percutaneous Achilles tendon repair. The majority of patients show good restoration of function by 3 months and a minor limitation at 6 months. The majority of the improvement in function occurred between 3 and 6 months following surgery. Two patients reported ongoing tendinopathic pain following repair increasing mean scores.

We believe this technique can be introduced in District General Hospitals to give good outcome on a cost effective basis.

Purpose

To critically evaluate exciting new technology to reconstruct menisci for the treatment of post menisectomy pain and relate results to indication and surgical technique in a non-inventor's general knee practice.

Methods

We present our early experience of two non-comparative series with different meniscal implants.

Series 1: Thirteen patients received a Menaflex implant (Regen Bio, USA). Mean age 30, male/female 11/2, mean length of implant 44mm, mean chondral grade 1.9 (Outerbridge). At 24 months clinical scores showed improvement in 12. Second look arthroscopy in 5 however showed disappointing amounts of regenerative tissue. One patient has been revised.

Series 2: Twelve patients received an Actifit implant (Orteq, UK). Mean age 38, male/female 8/4, mean length implant 43 mm, mean chondral grade 1.3. At 12 months all have improved clinical scores. We have performed two second looks, one of these showed excellent integration. However one showed only 50% regeneration. Critical review of the initial implantation shows that there may not have been adequate preparation of the host meniscus tissue.

We reviewed professional sportsmen who had undertaken Anterior Cruciate Ligament reconstruction to determine their actual and perceived sporting performance and long term outcome. The specific aim was to determine whether the players returned to the same standard of play, following reconstructive surgery. After IRAS approval, a questionnaire survey was distributed to 55 professional players on the Sports Injury Surgery ACL database. 24players returned questionnaires (response rate of 43.6%). Dates of surgery ranged from January 1998-February 2006. The mean elapsed time following surgery was 48 months (range 13-120 months). 12 patients had injured their left knee, 8 their right and 4 both knees. The respondents played rugby league 37% (9), soccer 33.3% (8), rugby union 21% (5) and netball 8.3% (2). 12 respondents were playing in the top leagues in their sports. 15 were regular first team players and 6 were squad players.

62.5% (15) thought they had returned to their previous standard of play, 29% (7) said that they had not and 2 did not know. 71% (17) of respondents thoughts their knee returned to normal however 25% (6) did not. The mean time for RTP was 10 months (5-21 months). Those that returned to the same standard were younger (21yrs) compared to those who did not (25yrs) (P=0.108). 4 players had torn the ACL in the opposite knee or ruptured their reconstruction. Additional meniscal injuries did not influence outcome and at 4 years most players had no or only slight symptoms with sport or activities of daily living. The rupture of the ACL is no longer a career ending injury for the professional sportsman. The majority (62.5%) of players will return to their pre-injury standard of play following reconstruction. The age at injury and additional meniscal injuries were not shown to be significant factors in this series.

Purpose: To report on our early experience with a synthetic meniscal substitute inserted for symptomatic post meniscectomy medial or lateral knee pain.

Methods and results: Six patients underwent underwent insertion of a collagen meniscal implant (Menaflex, Hospital Innovations, UK). These were inserted onto a trephinated rim of vascular meniscus to permit the structural incorporation of healing tissue. Specific rehabilitation included 8 weeks on crutches and restricted activity for 6 months. Patients were prospectively analysed documenting KOOS, IKDC, Lysholm and SF36 outcome scores.

All patients were male, 4 patients had deficiencies in the right knee, 2 the left knee and the mean patient age was 28.8years (range 17–45). Four CMI were inserted for lateral meniscal deficiencies, two medial. The mean length of implant sutured in place was 41mm (range 35–55). Median pre op scores were KOOS P/S/ADL/QOL 53/100, 54/100, 66/100, 25/100, 44/100, IKDC 49.43%, Tegner 3, SF-36 35.38 PCS and 27.48 MCS and Lysholm 87/100. The mean elapsed time post meniscectomy was 20 months (range 2–51). All but one of the implants used were 9.5mm in width and sizes ranged 35–45mm.

At early follow up there have been no complications and background pain has improved in all 6. MIR imaging has shown that none have separated. Post operative follow up suggest improved outcome.

Conclusion: Though this is very early data, close scuritny of new treatment options is essential. So far the clinical outcome is favourable and we believe that CMI may be beneficial in reducing post menisectomy pain. Hopefully, in the future CMI may become a means of preventing post meniscectomy osteoarthrtitis.

Introduction: Primary total hip replacement remains one of the commonest orthopaedic procedures performed. It is yet to be clearly demonstrated whether use of a postoperative drain is of benefit in these procedures.

Methods: We carried out a prospective randomised study comparing the use of autologous reinfusion drains, closed suction drains or no drain to determine their influence on allogenic blood transfusion requirements, length of hospital stay and infection rates. Stratification was carried out for confounding factors.

Results: 153 patients were recruited into the study and randomised to one of the three closely matched groups. There was no significant difference between the mean intra-operative blood loss or post-operative haemaglo-bin levels between the 3 groups. 42% of the suction drain group required post-operative transfusion as compared to 17% of the reinfusion drain group and 12% of the group with no drains. This difference was highly significant (P=0.02) Mean time for the wound to become dry was 3 days, 3.9 days and 4 days in the no drain, re-transfusion drain and suction drain groups respectively. This difference was statistically significant (P=0.03). There was no statistically significant difference in the mean length of inpatient stay.

Discussion: This study demonstrates a significantly higher transfusion rate with closed suction drains compared to reinfusion drains or no drains. With the drive to reduce hospital stay our study supports the considered use of no drain or a reinfusion drain.

It is well appreciated that thigh pain following recent arthroplasty surgery is likely to be due to prosthetic loosening or infection. Both these sequelae can lead to periprosthetic fracture presenting complex challenges to even experienced surgeons.

Revision arthroplasty patients are prone to both fatigue and insufficiency fractures as they may have reduced bone stock after previous surgery and reduced bone density secondary to medical and immobility reasons. The post operative painfree condition will frequently permit early load bearing leading to a relatively rapid increase in activity and load bearing.

Fatigue fractures occur in bone of normal quality subject to abnormal cyclical overloading, leading to resorption and eventual failure, before adequate time has passed to permit adaptive remodelling. Insufficiency fractures occur when normal physiological loads are applied to bone of abnormal quality.

Surprisingly few periprosthetic stress fractures are reported in the literature but a series notes lateral tensile stress fractures associated with varus prosthetic alignment. These all occurred near the tip of the prosthesis.

The case of an unusual Gruen Zone 2, Vancouver B1 stress fracture, 9 months following revision arthroplasty is reported. Initially loosening was suspected due to the development of load bearing thigh pain. Plain radiography revealed the development of a dreaded black line, consistent with a stress fracture. Bone scintigraphy revealed the typical appearance of a stress fracture in the absence of loosening or infection.

The unusual location of this stress fracture allowed consideration of conservative non weight bearing management which lead to the alleviation of symptoms rather than further revision surgery.

This report illustrates this unusual stress fracture and highlights the importance of careful loading practises to permit adequate remodelling following complex revision surgery.
